The cooperation of the 3GPP(third generationPartner's plan) LTE(Long Term Evolution) be the E-UMTS(evolution UMTS that uses E-UTRA)A part. This 3GPPLTE adopts OFDMA in downlink, and in up-linkMiddle employing SC-FDMA. Senior LTE(LTE-A) be the evolution version of 3GPPLTE. CanTo pass through IEEE802.16e(WirelessMAN-OFDMA frame of reference) and senior IEEE802.16m(WirelessMAN-OFDMA AS) explain WiMAX. For clearlyChu, explanation below focuses in 3GPPLTE and 3GPPLTE-A system. But, thisBright technical characterictic is not limited to this.

Fig. 1 exemplarily shows at third generation partner program Long Term Evolution (3GPPLTE)The radio frame structure using in system. Below with reference to Fig. 1, downlink (DL) is describedRadio frame structure. In cellular orthogonal frequency division multiplexing (OFDM) radio packet communication system,Carry out uplink/downlink data packet transmission taking subframe as unit. A subframe is by fixedJustice is the predetermined time interval that comprises multiple OFDM symbols. The support of 3GPPLTE standard is suitable forIn the Class1 radio frame structure of FDD (FDD) be applicable to time division duplex (TDD)Type 2 radio frame structures.

Fig. 1 (a) is the schematic diagram that the structure of Class1 radio frame is shown. Downlink wirelessElectricity frame comprises 10 subframes, and a subframe comprises two time slots at time zone. Sending outPenetrate the time interval in (TTI) and defined for launching the time that subframe is required. For example, oneIndividual subframe can have the length of 1ms, and time slot can have the length of 0.5ms.A time slot can comprise multiple OFDM symbols at time zone, and comprises at frequency domainMultiple Resource Block (RB). Because 3GPPLTE system is used OFDMA in downlink,So symbol duration of this OFDM symbol instruction. OFDM symbol can be called asSC-FDMA symbol or symbol duration. RB is resource allocation unit, and in the time of oneGap comprises multiple continuous carriers.

Can change the OFDM comprising at a time slot according to the configuration of Cyclic Prefix (CP)The quantity of symbol. CP comprises expansion CP and normal CP. For example,, if come by normal CPConfiguration OFDM symbol, the quantity of the OFDM symbol comprising at a time slot can be 7.If CP configures OFDM symbol by expansion, increase the length of an OFDM symbolDegree, the quantity of the OFDM symbol comprising at a time slot is less than the situation of normal CP. ExampleAs, the in the situation that of expansion CP, the quantity of the OFDM symbol comprising at a time slot canBeing 6. If channel status is unstable, for example, if subscriber equipment (UE) is to move at a high speedMoving, can use expansion CP to further reduce the interference between symbol.

In the situation that using normal CP, because a time slot comprises 7 OFDM symbols,So a subframe comprises 14 OFDM symbols. Now, the first two of each subframe or threeIndividual OFDM symbol can be assigned to physical downlink control channel (PDCCH), andRemaining OFDM symbol can be assigned to physical down link sharing channel (PDSCH).

In the structure of type 2 radio frames shown in Fig. 1 (b). Type 2 radio frames compriseTwo fields (half-frame), each field is by 5 subframes, down link pilot timeslot(DwPTS), protective time slot (GP) and uplink pilot time slot (UpPTS) form,Wherein, a subframe is made up of two time slots. , in the situation of not considering radio frame typeUnder, a subframe is made up of two time slots. DwPTS is used for carrying out search of initial zone, synchronousOr channel estimating. UpPTS is for carrying out the channel estimating of base station and subscriber equipment (UE)Line link transmitting is synchronous. Protect interval (GP) between up-link and downlink, withJust remove dry due to the multipath of down link signal producing of postponing to cause in up-linkDisturb. ,, in the situation that not considering radio frame type, a subframe is made up of two time slots.

The structure of radio frame is only exemplary. Therefore, can change in every wayThe quantity of the quantity of the subframe that radio frame comprises, the time slot comprising in subframe or at time slotThe quantity of the symbol comprising.

Fig. 2 is the schematic diagram that is illustrated in the resource grid in downlink time slots. Although at this figureIn downlink time slots comprise that in time domain 7 OFDM symbols and a RB are frequentlyTerritory comprises 12 subcarriers, but scope of the present invention or spirit are not limited to this. For example, existIn the situation of normal cyclic prefix (CP), a time slot comprises 7 OFDM symbols. But,The in the situation that of expansion CP, a time slot can comprise 6 OFDM symbols. At resource networkEach element on lattice is called as resource element. A RB comprises 12 × 7 resource elements.Determine the quantity of the RB comprising at downlink time slots based on downlink transmission bandwidthN^DL. The structure of uplink time slot can equal the structure of downlink time slots.

Fig. 3 is the schematic diagram that the structure of downlink subframe is shown. In a subframe firstAnterior maximum three control zones that OFDM symbol is assigned to corresponding to control channel of time slotTerritory. Remaining OFDM symbol is divided corresponding to physical down link sharing channel (PDSCH)The data area being fitted on. The base unit of transmitting becomes a subframe. In 3GPPLTE systemThe example of the downlink control channel using comprises for example physical control format indicator channel(PCFICH), physical downlink control channel (PDCCH), physical mixed are retransmitted automaticallyBid indicator channel (PHICH) etc. PCFICH is at an OFDM symbol place of subframeBe launched, and comprise the number about the OFDM symbol at subframe emission control channelThe information of amount. PHICH comprises the HARQ as the response for uplink transmitAck/nack signal. The control information of launching by PDCCH is called as downlink controlInformation (DCI). DCI comprises for the up-link of particular UE group or downlink scheduling letterBreath or up-link transmission power control command. PDCCH can comprise downlink sharied signal channel(DL-SCH) resource distribution and transmitting form, uplink shared channel (UL-SCH)Resource allocation information, PCH (PCH) paging information, about DL-SCH beSystem information, such as the higher level control of the accidental access response of launching on PDSCH (RAR)The resource of message distributes, for the one group of transmitting power control of each UE in particular UE groupThe activation of order, transmitting power control information, ip voice (VoIP) etc. Can be in control zoneThe multiple PDCCH of transmitting in territory. UE can monitor multiple PDCCH. Continuous at one or severalIn the set of control channel element (CCE), launch PDCCH. CCE is logical allocation unit,Its compiler rate for the state with based on radio channel provides PDCCH. CCE correspondenceIn multiple resource element groups. Between quantity based at CCE and the compiler rate that provided by CCECorrelation determine the form of PDCCH and the quantity of available bits. Base station basis will be to UEThe DCI of transmitting determines PDCCH form, and to the attached CRC of control information(CRC). According to the owner of PDCCH or make for utilizing the temporary transient identifier of radio net(RNTI) shelter CRC. If PDCCH, can be for CRC for particular UEShelter UE community-RNTI(C-RNTI). Alternatively, if PDCCH is used for pagingMessage, can shelter Paging Indicator identifier (P-RNTI) to CRC. If PDCCHFor system information (more specifically, system information block (SIB)), can cover to CRCCover system information identifier and system information RNTI(SI-RNTI). For indicate as forThe accidental access response of the response of the transmitting of the random access guiding of UE, can cover to CRCCover random access-RNTI(RA-RNTI).

Fig. 4 is the schematic diagram that the structure of uplink frame is shown. Uplink sub-frames can be frequentlyIn rate region, be divided into control area and data area. Comprise the thing of uplink control informationReason uplink control channel (PUCCH) is assigned to control area. Comprise user dataPhysical uplink link sharing channel (PUSCH) is assigned to data area. In order to keep single yearWave property, a UE launches PUCCH and PUSCH when different. For the PUCCH of a UEBe assigned to the RB couple in subframe. Belong to RB that this RB is right with respect to two Time Slot OccupanciesDifferent subcarriers. Therefore the RB, distributing to PUCCH at time slot edge place by " frequency hopping ".

Carrier aggregation

Although downlink and uplink bandwidth differ from one another, wireless communication system is commonUse a carrier wave. For example, can provide wireless communication system based on single carrier wave, this nothingLine communication system have for a carrier wave of each of downlink and up-link, withAnd symmetry between downlink and uplink bandwidth.

International Telecommunication Union asks the support of senior IMT candidate to compare traditional wireless communicationThe bandwidth that system is wider. But in the world most, the distribution of wide frequency bandwidth is tiredDifficult. Therefore, be called as carrier aggregation (bandwidth polymerization) or spectrum aggregating, for effectivelyRate ground uses the technology of the band of subsection to be developed to multiple physics bands are aggregated to widerLogical band.

Carrier aggregation is introduced into support the handling capacity of increase, prevents the introducing by broadband RF deviceCaused cost increases, and the compatibility of guarantee and legacy system. Carrier aggregation enable passCross the exchanges data of one group of carrier wave between UE and eNB, each tool in this group of carrier waveHave at the legacy wireless communication system (3GPPLTE for example,, at 3GPPLTE-A in the situation thatVersion 8 or version 9) the middle bandwidth unit defining. Each has in legacy wireless communication systemThe carrier wave of the bandwidth unit of middle definition can be called as component carrier (CC). Use one or manyThe carrier aggregation of individual CC can be applied to each in downlink and up-link. Carrier wavePolymerization can be supported the system bandwidth up to 100MHz by following manner: polymerization reaches 5Individual CC, each CC has 5,10 or the bandwidth of 20MHz.

Downlink CC and up-link CC can be represented as respectively DLCC and ULCC.Carrier wave or CC can be represented as community in the function in 3GPPLTE system. Therefore, DLCC and ULCC can be called as respectively HeUL community, DL community. Below, will use term" carrier wave ", " component carrier ", " CC " or " community " represent multiple years that carrier aggregation is applied toRipple.

Although illustrated example below ground uses eNB(BS) or community be used as downlinkTransmitting entity, and exemplarily use UE as uplink transmit entity, but the present inventionScope or spirit be not limited to this. , even when via node (RN) being used as from eNBTo the downlink transmission entity of UE or as the up-link receiving entity from UE to eNBTime, even if or can be used as for the uplink transmit entity of UE or be used as RNDuring from the downlink receiving entity of eNB, it should be noted that and can apply without difficulty thisBright embodiment.

Downlink carrier polymerization can be described as eNB be supported in time resource (taking subframe asUnit distributes) in frequency resource (subcarrier or the Physical Resource Block of one or more carrier wave bands[PRB]) in to the downlink transmission of UE. Uplink carrier polymerization can be described to UEThe frequency resource of the one or more carrier wave bands in time resource (distributing taking subframe as unit)In (subcarrier or PRB) to the uplink transmit of eNB.

Fig. 5 illustrates physical layer (ground floor, L1) and the MAC layer (of multicarrier back-up systemTwo layers, L2). Referring to Fig. 5, support eNB or the BS of the legacy wireless communication system of single carrierComprise a physical layer (PHY) entity that can support a carrier wave, and can be to eNBBe provided for controlling a media Access Control (MAC) entity of a PHY entity. For example,Can in PHY layer, carry out Base-Band Processing. For example, can in MAC layer, carry out not only bagDraw together the MACPDU(protocol Data Unit of transmitter) create and comprise MAC/RLC sublayerL1/L2 scheduler operation. The MACPDU grouping block of MAC layer is by logic transport layer quiltBe converted to transmission block, make the transmission block obtaining be mapped to physical layer input block. At Fig. 5In, MAC layer is represented as whole L2 layer, and at conceptive covering MAC/RLC/PDCPSublayer. Understand for convenience of description and better the present invention, can retouch at MAC layer of the present inventionIn stating, use interchangeably above-mentioned application.

On the other hand, multicarrier back-up system can provide multiple MAC-PHY entities. More detailedThin, can find out from Fig. 5 (a), can be so that a MAC-PHY entity be mapped toEach mode in n component carrier (n CC) is carried out sending out of allocating multiple carrier back-up systemEmitter and receiver. Assign independently PHY layer and independently MAC layer to each CC,Make the scope from MACPDU to PHY layer, to create for each CC'sPDSCH。

Alternatively, multicarrier back-up system can provide a public MAC entity and multiplePHY entity. , as shown in Figure 5 (b), the system that multicarrier is supported can be with following sideFormula comprises that transmitter and receiver: n PHY entity corresponds respectively to n CC, and canIn each of transmitter and receiver, there are public affairs for controlling this n PHY entityMAC entity altogether. In this case, can pass through from the MACPDU of a MAC layerTransport layer is branched to the multiple transmission blocks corresponding with multiple CC. Alternatively, when at MACWhile producing MACPDU in layer or when produce RLCPDU in rlc layer time, can be by MACPDU or RLCPDU branch into each CC. As a result, can in PHY layer, produce for everyThe PDSCH of a CC.

For launching the L1/L2 control signal control letter producing from the packet scheduler of MAC layerThe PDCCH of breath can be mapped to the physical resource for each CC, is then launched.Each CC place that can be launched at corresponding PDSCH/PUSCH in this case,The PDCCH that encodes respectively, this PDCCH comprise for to particular UE transmitting PDSCH orThe control information (DL assigns or UL license) of PUSCH. PDCCH can be called as independenceCompiling PDCCH. On the other hand, can in a PDCCH, configure several CC'sPDSCH/PUSCH emission control information, makes to launch configured PDCCH. ShouldPDCCH can be called as the PDCCH of associating compiling.

In order to support carrier aggregation, need to be based upon BS(or eNB) and UE(or RN) itBetween connection, and connection that need to be between BS and the UE preparation of setting up, passable to makeEmission control channel (PDCCH or PUCCH) and/or shared channel (PDSCH or PUSCH).In order to carry out above-mentioned connection or to connect foundation for particular UE or RN, need to be used for eachThe measurement of carrier wave and/or report, and can assign the CC as measurement and/or reporting objectives.In other words, CC assigns and represents: not only considering the UL/DLCC constructing in comfortable BSAmong particular UE (or RN) ability and also consider in the situation of system environments and set up and useIn the CC(of the DL/UL transmitting instruction quantity of CC and the index of CC).

In this case, when controlling in the 3rd layer of (L3) provided for radio resources management (RRM)When CC assigns, can use the specific or specific RRC signaling of RN of UE. Alternatively, canSpecific or the specific RRC signaling of cell cluster with use community. Need to be all if assigned for CCAs a series of CC activate/forbid the dynamic control arranging, predetermined PDCCH can be used forL1/L2 control signal, or, the special physics control of assigning control information for CC can be usedThe PDSCH of channel processed or L2MAC message format. On the other hand, if adjusted by groupingDegree device is controlled CC and is assigned, and predetermined PDCCH can be used for to L1/L2 control signal, canTo use the physical control channel that is exclusively used in CC appointment control information, or can use with L2The PDSCH of the form configuration of MAC message.

Fig. 6 is diagram downlink (DL) and up-link (UL) component carrier (CC)Concept map. Referring to Fig. 6, can be from eNB(community) or RN assign DL and ULCC.For example, the quantity of DLCC can be set to N, and the quantity of ULCC can be set upFor M.

By initial access or the initial deployment processing of UE, based on little for DL or UL(Area searching) a specific CC(for example, system information is obtained/is received, initial random access placeReason etc.) set up RRC connect after, can from dedicated signaling (the specific RRC signaling of UE orThe specific L1/L2PDCCH signaling of UE) the unique carrier wave that is provided for each UE sets up.For example, suppose conventionally taking eNB(community or cell cluster) realize the carrier wave for UE as unitSet up, also can pass through the specific RRC signaling in community or the public L1/L2 of community particular UEPDCCH signaling provides UE carrier wave to set up. In another example, in eNB, useCarrier component information can be signaled to by connecting for RRC the system information of setting upUE, or also can connect and be signaled to other system information while setting up completing RRCOr the specific RRC signaling in community.

Although having described DL/ULCC centered by the relation between eNB and UE buildsVertical, the invention is not restricted to this, but RN also can provide to the UE comprising in RN regionDL/ULCC sets up. In addition, with the RN comprising in eNB region explicitly, eNBAlso can provide the DL/ULCC of corresponding RN to set up to the RN in eNB region. For clearlyChu, although description is below by the relation based between eNB and UE and open DL/ULCCSet up, but it should be noted that at RN and UE(identical content also can be applied to,Access up-link and downlink) between relation or the relation between eNB and RN (returnJourney up-link or downlink), and do not depart from scope of the present invention or spirit.

In the time assigning above-mentioned DL/ULCC to each UE, can join by specific signalingNumber definition impliedly or clearly configures DL/ULCC link.

Channel condition information (CSI) feedback

In order correctly to carry out MIMO technology, receiver can feed back order designator to transmitter(RI), pre-coding matrix index (PMI) and CQI (CQI). RI, PMICan generally be called as where necessary channel condition information (CSI) with CQI. Alternatively, artLanguage " CQI " can be used as the concept of the channel information that comprises RI, PMI and CQI.

Figure 16 is the concept map of the feedback of diagram channel condition information.

Receiver can select preferably from code book based on received signalPre-coding matrix, and can feed back selected PMI to transmitter. In addition, receiverCan measure the Signal Interference and Noise Ratio (Signal-to-Interferenceplus of reception (Rx) signalNoiseRatio) (SINR), calculate channel quality information (CQI) and feed back to transmitterThe CQI calculating. In addition, receiver can measure reception (Rx) signal signal disturb make an uproarAcoustic ratio (SINR), calculates CQI and feeds back the SINR calculating to transmitter. In addition,Receiver can feed back to transmitter the order designator (RI) of Rx signal. Transmitter can useDetermine from RI and the CQI information of receiver feedback the layer being suitable for to the data transmission of receiverQuantity and time/frequency resource, MCS(modulation and compilation scheme) etc. In addition, receiverCan use by the pre-coding matrix (W from the PMI instruction of receiver feedback by multiple antennas_l）Launch precoding Tx signal.

Below will describe channel condition information in detail.

RI is information about the channel sequence quantity of the data transmission layer of transmitter (, for).Can pass through the quantity of distributed Tx layer and determine RI, and can be from the descending chain being associatedRI is obtained in road control information (DCI).

PMI is the information about the pre-coding matrix of the data transmission for transmitter. Can beConsider that the situation of quantity of the layer of being indicated by RI gets off to determine the precoding square feeding back from receiverBattle array. Can be in Closed-Loop Spatial Multiplexing (SM) and the large feelings that postpone cyclic delay diversity (CDD)Under condition, feed back PMI. In the situation that open loop is launched, transmitter can select according to pre-defined ruleSelect pre-coding matrix. For select for the processing of the PMI of each order (order 1 to 4) asUnder. Receiver can calculate the post processing SINR in each PMI, by calculated SINRBe converted to and capacity, and based on selecting best PMI with capacity. , can be by receptionThe PMI of device calculates the processing of regarding as for based on searching for best PMI with capacity. From connecingThe transmitter that receipts device receives PMI feedback can use the pre-coding matrix of being recommended by receiver.This fact can be used as 1 bit indicator and is comprised in the tune for the data transmission to receiverIn degree assignment information. Alternatively, transmitter can not use from the PMI of transmitter feedback and refer toThe pre-coding matrix showing. In this case, can in dispatching distribution information, comprise clearly useIn the pre-coding matrix information of the data transmission from transmitter to receiver. For the details of PMI,Can for example, referring to 3GPP normative document (, 3GPPTS36.211).

CQI is the information about channel quality. Can combine to represent CQI by predetermined MCS.Can provide CQI index, as shown in table 3 below.

[table 3]

Referring to table 3, represent CQI index (, CQI index 0 15) by 4 bits.Modulation scheme and compiler rate can be indicated in each CQI index.

CQI computational methods below will be described. For example, at 3GPP normative document (, 3GPPTS36.213) in, definition is for allowing UE to calculate hypothesis (1) below CQI index to (5).

(1) taken first three the OFDM symbol in a subframe by control signal.

(2) do not exist by master sync signal, auxiliary synchronous signal or Physical Broadcast Channel (PBCH)The resource element (RE) using.

(3) suppose the CP length of non-MBSFN subframe.

(4) redundancy versions is set to zero (0).

(5) PDSCH launching technique can depend on the current emission mode configuring in UE(for example, default mode).

(6) can be except ρ_AOutside provide the energy of the every resource element of PDSCHEPRE()Ratio with cell specific reference signal EPRE. (ρ_ADetailed description can follow belowSuppose. If it is specific to be set to have Si Ge community for the UE of any modulation schemeThe emission mode 2 of antenna port or can be set to have RI be that 1 He Sige community is specificThe emission mode 3 of antenna port, can pass through ρ_A=P_A+Δ_offset+10log₁₀(2)[dB]Represent ρ_A. In remaining situation, be associated with the quantity of any modulator approach and random layer,Can pass through ρ_A=P_A+Δ_offset[dB] represents ρ_A. Can be by by higher level signal deploymentNomPDSCH-RS-EPRE-Offset parameter provides Δ_offset）

The definition of above-mentioned hypothesis (1) to (5) can indicate CQI not only to comprise CQI, andComprise the various information of corresponding UE. , can be according under identical channel quality correspondingHandling capacity or the performance of UE feed back different CQI indexes, make to need definition forState the predetermined reference of hypothesis.

UE can be from eNB receiving downlink reference signal (DLRS), and based on connectThe DLRS receiving carrys out identification channel state. In this case, RS can be at traditional 3GPPLTEThe public reference signal (CRS) defining in system, and can be to there is the sky toe-in of expansionFor example, in the system (, 3GPPLTE-A system) of the structure channel state information reference signals of definition(CSI-RS). UE can meet for the channel place by reference to signal (RS) identificationCQI calculates the hypothesis providing, and calculates wherein piece error rate (BLER) simultaneously and be not more than 10%CQI index. UE can launch the CQI index calculating to eNB. UE can be not toCQI index calculation is processed application for improving the method for Interference Estimation.

According to UE implementation, define in every way for allowing UE identification channel stateWith the processing of calculating suitable MCS. For example, UE can use reference signal (RS) to countCalculate channel status or effective SINR. In addition, can be in whole system bandwidth (also referred to as " S set ")Upper measurement channel status or effectively SINR or also can be in some bandwidth (particular sub-band or specificRB) upper channel status or the effective SINR of measuring. CQI for S set can be called as wideBand WBCQI, and can be called as subband (SB) CQI for the CQI of some bandwidth.UE can channel status or effective SINR based on calculated calculate the highest MCS. The highestMCS can indicate and during decoding, meet CQI calculating hypothesis and be no more than 10% transmission block mistakeThe MCS of rate. UE can determine the CQI index relevant to calculated MCS, and canTo report determined CQI index to eNB.

In addition, can consider only CQI transmitting, wherein, UE only launches CQI. From eNBWhile receiving request, CQI transmitting aperiodic can be by Event triggered. Such from eNBRequest can be to be asked by the CQI of a bit definitions on DCI form 0. In addition, forOnly CQI transmitting can signal MCS index (I as shown in table 4 below_MCS）29. In this case, the CQI request bit of DCI form 0 is set to 1, can configure 4Redundancy versions 1(RV1 is indicated in individual RB or less transmitting in PUSCH data re-transmitting),And can be by order of modulation (Q_m) be set to 2. In other words, in the feelings of the transmitting of CQI onlyUnder condition, can be only by QPSK(QPSK) scheme is as modulation scheme.

Below will describe CQI report operation in detail.

In 3GPPLTE system, for example, when DL receiving entity (, UE) is coupled to DLFor example, when transmitting entity (, eNB), measure at any time the reference via downlink transmissionSignal received power (RSRP) and Reference Signal Received Quality (RSRQ), and can weekPhase ground or Event triggered ground are to eNB report measurement result.

In cellular OFDM radio packet communication system, each UE can be via uplinkThe channel information of the DL based on DL channel condition is reported on road, and eNB can determine time/Frequency resource and MCS(modulation and compilation scheme) to use the DL receiving from each UEChannel information comes to each UE transmitting data.

For example, in the situation of traditional 3GPPLTE system (, 3GPPLTE version 8 systems),Such channel information can be indicated by channel quality (CQI), precoding matrix indicators (PMI)Form with order instruction (RI). Can launch CQI, PMI according to the emission mode of each UEWith all or some of RI. Can determine CQI by the received signal quality of UE. Conventionally,Can determine CQI based on DLRS measurement. In this case, be in fact applied to eNBCQI value can be corresponding to MCS, in MCS, UE is at measured Rx signal qualityPlace's maintenance 10% or less piece error rate (BLER), and there is maximum handling capacity simultaneouslyOr performance. In addition, can be when receive request from eNB, by such channel information reportingScheme is divided into cycle report or report aperiodic.

By 1 bit that comprises the uplink scheduling information sending from eNB to UECQI request field is assigned the information about report aperiodic to each UE. Receive non-Cycle, each UE can pass through physical uplink link sharing channel (PUSCH) when report informationConsider the channel information of the emission mode of UE to eNB transmitting. If need, needn't lead toCross same PUSCH and launch RI and CQI/PMI.

In the situation that reporting aperiodic, can be with the unit of subframe to each UE signalNotice is wherein launched circulation, the skew in corresponding cycle etc. of channel information via upper layer signal,And can be with the interval of the scheduled time, by physical uplink control channel (PUCCH)Consider the channel information of transmitting (Tx) pattern of each UE to eNB transmitting. ThereinIn subframe channel information being transmitted at the interval of the scheduled time, there is UL transmitting dataIn situation, corresponding channel information can be not by PUCCH but by PUSCH and dataTransmitting together. In the case of the cycle report by PUCCH, compare with PUSCH,Can use the bit of limited quantity. Can by same PUSCH launch RI andCQI/PMI. If cycle report conflicts with report aperiodic, only can be in identical subframeCarry out report aperiodic.

In order to calculate WBCQI/PMI, can use up-to-date transmitting RI. Report at PUCCHIn announcement pattern, RI can be independent of another RI using in PUSCH Report mode. RIThe CQI/PMI place that can only use in corresponding PUSCH Report mode is effective.

CQI/PMI/RI feedback kind for PUCCH Report mode can be categorized as to four kindsFeedback kind (Class1 is to type 4). Class1 is the CQI for the subband of user's selectionFeedback. Type 2 is WBCQI feedback and WBPMI feedback. Type 3 is RI feedbacks. ClassType 4 is WBCQI feedbacks.

Referring to table 5, in the case of the cycle report of channel information, anti-according to CQI and PMIReport mode is categorized as four kinds of Report modes (pattern 1-0,1-1,2-0 and 2-1) by feedback type.

[table 5]

According to CQI feedback kind, Report mode is categorized as to broadband (WB) CQI and subband (SB)CQI. According to the transmitting of PMI or do not launch Report mode is categorized as without PMI and single PMI.Can be as seen from Table 5, " without PMI " can be corresponding to wherein using open loop (OL), transmitting pointThe exemplary cases of collection (TD) and single antenna, and " single PMI " can be corresponding to wherein usingThe exemplary cases of closed loop (CL).

Pattern 1-0 can indicate and wherein not launch PMI but only launch the exemplary of WBCQISituation. The in the situation that of pattern 1-0, can only spatial reuse (SM) in the situation that, launchRI, and can launch a WBCQI who is represented by 4 bits. If RI is greater than " 1 ",Can launch the CQI for first generation code word. The in the situation that of pattern 1-0, feedback kind 3Can be re-used at the different time points place within the predetermined report period with feedback kind 4, then byTransmitting. Above-mentioned pattern 1-0 launch scenario can be called as based on Time Division MultiplexingChannel information transmitting.

Pattern 1-1 can indicate the exemplary cases of wherein launching single PMI and WBCQI.In this case, can side by side launch 4 bit WBCQI and 4 bit WB with RI transmittingPMI. In addition, if RI is greater than " 1 ", can launch 3 bit WB space differential CQI.In the case of the transmitting of two code words, WB space differential CQI can be indicated for generationThe WBCQI index of code word 1 and for the difference value between the WBCQI index of code word 2.These difference values can be assigned to set 4 ,-3 ,-2 ,-1,0,1,2,3}, and everyA difference value can be assigned to any one in the value comprising in this set, and by 3Individual bit represents. The in the situation that of pattern 1-1, feedback kind 2 and feedback kind 3 can be in advanceSurely report that the different time points place in the period is multiplexing, be then launched.

Pattern 2-0 can indicate the CQI that does not have PMI to be launched and launch the band of UE selection.In this case, can Open-Loop Spatial Multiplexing (OLSM) in the situation that, only launch RI, canThe WBCQI being represented by 4 bits with transmitting. In each portions of bandwidth (BP), canWith transmitting Best-1CQI, and can represent Best-1CQI by 4 bits. In addition,Can further launch the designator of L the bit that is used to indicate Best-1. If RI is greater than " 1 ",Can launch the CQI for first generation code word. The in the situation that of pattern 2-0, above-mentioned feedbackClass1, feedback kind 3 and feedback kind 4 can be in the predetermined different time points of reporting in the periodPlace is re-used, and is then launched.

Pattern 2-1 can indicate and wherein launch the single PMI of band and the showing of CQI that UE selectsExample implementations. In this case, side by side launch the WBCQI, 3 of 4 bits with RI transmittingThe WB space differential CQI of bit and the WBPMI of 4 bits. In addition, can be at eachPortions of bandwidth (BP) locates to launch the Best-1CQI of 4 bits simultaneously and the Best-1 of L bit refers toShow symbol. If RI is greater than " 1 ", can launch the Best-1 space differential CQI of 3 bits.During the transmitting of two code words, can indicate at the Best-1CQI of code word 1 index andDifference value between the Best-1CQI index of code word 2. In pattern 2-1, above-mentioned is anti-Feedback Class1, feedback kind 2 and feedback kind 3 can be at the predetermined different times of reporting in the periodPoint place is re-used, and is then launched.

In the SBCQI Report mode of selecting at UE, define BP(band by table 6 belowWide part) size of subband.

[table 6]

Table 6 illustrates according to the BP of big or small each portions of bandwidth (BP) of system bandwidth joinsPut and subband size. UE can be chosen in the preferred subband in each BP, and calculates and useIn the CQI of corresponding subband. In table 6, if system bandwidth is set to 6 or 7, thisMean the quantity of the size of applying subband not and portions of bandwidth (BP). , 6 or 7 systemBandwidth means WBCQI only, there is no the application of the BP of subband state and 1.

Figure 17 illustrates the example of the CQI Report mode of UE selection.

The quantity of the RB of whole bandwidth. Whole bandwidth can be divided into N CQISubband (1,2,3 ..., N). A CQI subband can be included in the k of definition in table 6Individual RB. If do not represent the quantity of the RB of whole bandwidth by the integral multiple of k, canDetermine at last CQI subband (, N CQI subband) by equation 14 belowIn the quantity of the RB that comprises.

[equation 14]

In equation 14,Represent floor (floor) operation, andOr floor (x) representsBe not more than the maximum integer of " x ".

In addition, N_JA BP of CQI subband structure, and whole bandwidth can be divided into JIndividual BP. UE can calculate a preferred Best-1CQI for comprising at a BPThe CQI index of subband, and launch calculated CQI index by PUCCH. At thisIn situation, also can launch and be used to indicate in a BP, to select which Best-1CQI subbandBest-1 designator. Best-1 designator can be made up of L bit, and L can by underThe equation 15 of face represents.

[equation 15]

In equation 15,Can represent ceiling (ceiling) operation, andOrCeiling (x) can represent to be not more than the smallest positive integral of " x ".

In the CQI Report mode of selecting at above-mentioned UE, can be identified for CQI index meterThe frequency band of calculating. Below, will be discussed in more detail below CQI transmitting circulation.

Each UE can carry out reception information by RRC signaling, and this information is by channel informationTransmitting circulation and constituting with respect to the skew on upper strata. UE can be based on received channelInformation transmitting cyclical information comes to eNB transmitting channel information.

Figure 18 is that diagram is for making UE can launch periodically the concept of the method for channel informationFigure. For example, if receiving wherein channel information transmitting circulation, UE is set to 5 and skewBe set to 1 combined information, UE launches channel information taking 5 subframes as unit,On the augment direction of the subframe index based on the 0th subframe, assign a sub-vertical shift, and canTo carry out assigned channels information by PUCCH. In this case, subframe index can be by system-frameQuantity (n_f) and 20 time slot index (n existing in this system-frame_s, 0～19) combinationForm. A subframe can be made up of 2 time slots, makes to pass through 10 × n_f+floor(n_s/2)Represent subframe index.

Can according to CQI feedback kind classify for only launch one type of WBCQI andFor launching the two another kind of type of WBCQI and SBCQI. Only for launching WBIn the situation of the first kind of CQI, launching with each CQI transmitting circulation corresponding subframe placeFor the WBCQI information of whole band. WB cycle CQI feedback transmitting circulation can be arrangedBe 2,5,10,16,20,32,40,64,80 or 160ms in any one, orCan not set up the transmitting of WB cycle CQI feedback transmitting circulation. In this case, if neededTo launch PMI according to the PMI feedback kind of table 5, launch PMI information together with CQI.In the case of for launching the two the second type of WBCQI and SBCQI, Ke YijiaoFor ground transmitting WBCQI and SBCQI.

Figure 19 be diagram according to the embodiment of the present invention for launch WBCQI and SBCQI thisThe concept map of both methods. Figure 19 illustrates the example system being made up of 16 RB. IfBand system band is made up of for example 16 RB, and supposition can configure two portions of bandwidth (BP)(BP0 and BP1), each BP can be by 2 subbands (SB) (SB0 and SB1)Form, and each SB can be made up of 4 RB. In this case, as at table 6In aforesaid, determine the quantity of BP according to the quantity of the RB comprising in whole system bandWith the size of each SB, and can be according to the quantity of the quantity of RB, BP and SBSize is determined the quantity of the SB comprising in each BP.

In the case of for launching the two type of WBCQI and SBCQI, WBCQIBe launched into CQI transmitting subframe. In next one transmitting subframe, be transmitted in the SB0 at BP0 placeWith a SB(with good channel status in SB1, Best-1) CQI and phaseThe index (, Best-1 designator) of the SB answering. In other next one transmitting subframe,Be transmitted in a SB(with good channel status among SB0 and the SB1 at BP1 place,Best-1) index (, Best-1 designator) of CQI and corresponding SB. In transmittingAfter WBCQI, sequentially launch the CQI of each BP. In this case, comply with for one to four timeOrder transmitting is positioned at a transmitting WBCQI once and will launches after a WBCQIThe CQI of BP between the 2nd WBCQI. For example, if between two WBCQI timeBetween the once CQI of each BP of interim transmitting, can with WBCQI → BP0CQI →The order of BP1CQI → WBCQI is launched CQI. In another example, if at twoDuring the time interval between WBCQI, launch the CQI of four each BP, can be withWBCQI→BP0CQI→BP1CQI→BP0CQI→BP1CQI→BP0CQIThe order of → BP1CQI → BP0CQI → BP1CQI → WBCQI is launched CQI. LogicalCrossing higher level signals about the BP during the time interval between two WBCQIThe information of the sequentially emitting times of CQI. In the situation that not considering WBCQI or SBCQI,Can launch the group that circulates and be offset with the channel information signaling from the higher level of Figure 18In the corresponding subframe of the information of closing, launch the sequentially transmitting about BPCQI by PUCCHThe above-mentioned information of number of times.

In this case, if also need to launch PMI according to PMI feedback kind, necessaryLaunch PMI information and CQI simultaneously. If exist for UL data and send out in corresponding subframeThe PUSCH penetrating, CQI and PMI can come and number by PUSCH instead of PUCCHAccording to transmitting together.

Figure 20 be diagram when launch WBCQI and SBCQI the two time exemplary CQI send outPenetrate the concept map of scheme. More specifically, wherein will if signaled as shown in Figure 18Channel information transmitting circulation be set to 5 and skew be set to 1 combined information, and comply withThe once BP information between two WBCQI/PMI parts of order transmitting, Figure 20 illustrates UEThe example of channel information firing operation.

On the other hand, in the situation that RI launches, can by being used to indicate how many WBCQI/PMI transmitting is cycled to used in a signal of RI transmitting and the skew of corresponding transmitting circulationThe information of combination signals RI. In this case, skew can be defined as forThe relativity shift of CQI/PMI transmitting skew. For example,, if CQI/PMI is launched to the inclined to one side of circulationMove be set to 1 and the skew of RI transmitting circulation be set to 0, the skew of RI transmitting circulationCan be identical with the skew of CQI/PMI transmitting circulation. Can be by the skew definition of RI transmitting circulationFor negative value or zero.

Figure 21 is the concept map of the transmitting of diagram WBCQI, SBCQI and RI. In more detail,The lower RI transmitting of the CQI/PMI transmitting circulation that Figure 21 is illustrated in Figure 20 is WBCQI/PMI transmittingOne times of circulation, and the skew of RI transmitting circulation is set to " 1 ". Because RI launches circulationBe one times that WBCQI/PMI transmitting circulates, follow so RI transmitting circulation has the identical timeRing. Relative mistake between the RI of Figure 20 deviant " 1 " and CQI skew " 1 " is set to " 1 ",Make to launch RI based on subframe index " 0 ".

In addition, if RI transmitting is overlapping with WBCQI/PMI transmitting or SBCQI/PMI transmitting,WBCQI/PMI or SBCQI/PMI can decline. For example,, if RI skew is set to " 0 "Instead of " 1 ", WBCQI/PMI transmitting subframe and RI transmitting subframe are overlapping. In this situationUnder, WBCQI/PMI can decline, and can launch RI.

By above-mentioned combination, can launch CQI, PMI and RI, and can be by higherThe RRC signaling of layer is launched such information from each UE. BS(or eNB) can considerTo the channel situation of each UE with at BS(or eNB) in the distribution situation of the UE that comprisesLaunch suitable information to each UE.

Therebetween, can represent to be associated with PUCCH Report Type by table 7 belowThe payload size of SBCQI, WBCQI/PMI, RI and WBCQI.

[table 7]

Below, will be described in CQI, the PMI on PUSCH and launch the aperiodic of RI.

In the situation that reporting aperiodic, can by same PUSCH launch RI andCQI/PMI. In aperiodic Report mode in the situation that, RI report can be only for accordinglyCQI/PMI report in aperiodic Report mode effectively. Can be right shown in table 8 belowThe CQI-PMI combination being supported in all order values.

[table 8]

The pattern 1-2 of table 8 can indicate WB feedback. In pattern 1-2, can only existUnder the hypothesis of the transmitting in corresponding subband, select to be used for the excellent of each subband from code book subsetThe pre-coding matrix of choosing. UE can report a WBCQI at each code word place, andCan under following hypothesis, calculate WBCQI: on the subband of whole system bandwidth (S set)Transmitting data, and on each subband, use the corresponding pre-coding matrix of selecting. UE canTo report for the selected PMI of each subband. In this case, can be as belowShown in table 9, provide subband size. In table 9, if system bandwidth is set to 6 or 7,This means not applying subband size. , 6 or 7 system bandwidth means and only applies WBCQI and not applying subband state.

[table 9]

In table 8, mode 3-0 and mode 3-1 show by higher level (being also referred to as upper strata)The subband feedback of configuration.

In mode 3-0, UE can be reported in the total system bandwidth of set-S() on subbandThe WBCQI value of calculating under the hypothesis of data transmission. UE also can report for each subbandA subband CQI value. Can only under the hypothesis at the data transmission at corresponding subband place, countOperator band CQI value. Even at RI > 1 in the situation that, WBCQI and SBCQI can indicateFor the channel quality of code word 1.

In mode 3-1, under the hypothesis of data transmission that can be on set-S subband from codeThis subset is selected single pre-coding matrix. UE can report for each generation on each subbandA SBCQI value of code word. Single pre-coding matrix that can use in all subbands andUnder the hypothesis of the data transmission on corresponding subband, calculate SBCQI value. UE can report and be used forThe WBCQI value of each code word. Single precoding square that can use in all subbandsUnder the hypothesis of battle array and the data transmission on set-S subband, calculate WBCQI value. UE can reportAccuse the precoding matrix indicators of a selection. Can use 2-ratio by difference WBCQI valueSpecial subband differential CQI is offset to represent the SBCQI value for each code word. , canSubband differential CQI skew is defined as to poor between SBCQI index and WBCQI indexScore value. Can to four values, { 2,0 ,+1, any one in+2} assigns subband differential CQI inclined to one sideMove. In addition, can as shown in table 7 below, provide subband size.

In table 8, pattern 2-0 and pattern 2-2 illustrate the subband feedback that UE selects. Pattern2-0 and pattern 2-2 illustrate the report of best-M mean value.

In pattern 2-0, UE can select one group among whole system bandwidth (S set)M preferred subband (, best-M). The size of a subband can be given as k, andCan as shown in table 10 below, provide k and M value for each set-S scope.In table 10, if system bandwidth is set to 6 or 7, this means that applying subband is not largeLittle and M value. , 6 or 7 system bandwidth means only applies WBCQI, and does not applySubband state.

UE can report a CQI value, and only at best-M subband (, this CQI value reflectsM the subband of selecting) data transmission located. This CQI value can be indicated even at RI > 1 feelingsUnder condition for the CQI of code word 1. In addition, UE can be reported in the data on set-S subbandThe WBCQI value of calculating under the hypothesis of transmitting. WBCQI value can be indicated even at RI > 1In situation for the CQI of code word 1.

[table 10]

In pattern 2-2, UE can be from set-S subband (wherein, the size quilt of a subbandAmong being set to k), select one group of M preferably subband (, best-M). Meanwhile, canAmong code book subset, select the subband of a preferred pre-coding matrix for selecting at MOn data transmission. UE can report for each code word under following hypothesisCQI value: on M the subband of selecting, realize data transmission, and in each of M subbandPre-coding matrix is selected in individual middle use. UE can report that of selecting for M subband prelistsThe designator of code matrix. In addition, can under following hypothesis, among code book subset, select oneIndividual pre-coding matrix is (, different from the pre-coding matrix of M the subband of selecting for above-mentionedPre-coding matrix): on set-S subband, realize data transmission. UE can be in each generationCode word place is reported in the WBCQI calculating under following hypothesis: on set-S subband, realize dataTransmitting, and in all subbands, use a pre-coding matrix. UE can with all subband phasesReport the designator of a selected pre-coding matrix associatedly.

The entirety of the subband feedback model (pattern 2-0 and pattern 2-2) of selecting with UE is associatedGround, UE can use combined index (r) to report the part of M the subband of selecting, wherein,Can represent r by equation 16 below.

[equation 16]

In equation 16, set(1≤s_i≤N，s_i＜s_i+1) can compriseThe subband index of M classification. In equation 14,Binomial coefficient that can indication extension,It is set to the in the situation that of x >=y $\left(\begin{array}{c}x\\ y\end{array}\right),$ And be set to zero in the situation that of x < y. CauseThis, r can have unique tags, and can be by $r\&Element;\{0,\&CenterDot;\&CenterDot;\&CenterDot;,\left(\begin{array}{c}N\\ M\end{array}\right)-1\}$ Represent.

In addition, can represent for each by the relative mistake score value being associated with WBCQIThe CQI value of the M of individual code word the subband of selecting.

Can represent to be used to indicate M subband (, the best-M selecting by L bitSubband) each the label of position, wherein, pass throughRepresent L.

For the feedback information of many MIMO emission mode

As mentioned above, need channel condition information (CSI) to come to launch for MIMO. CanFeed back CSI from receiver to transmitter. Transmitter can obtain from CSI can be in response to channel shapeState and the precoding weighting that used adaptively. In addition, transmitter can be from by precodingThe CSI that adds weight update obtains signal transmitting information and launches for MIMO. For example, this signalTransmitting information can comprise order of modulation, compiler rate, transport block size, scheduling band etc.

Receiver can use the reference signal (RS) from transmitter receipt to obtain at transmitterAnd channel condition information (CSI) between receiver, and can feed back to transmitter (orReport) CSI that obtains. In this case, can reduce to feed back by several different methodsThe quantity of CSI. For example, can represent channel quality information/index by the bit quantizing(CQI), pre-coding matrix index (PMI), order designator (RI) etc., make to reduce anti-The quantity of feedforward information, causes the effectively realization of transmitting.

Specifically, change about the letter of order that is suitable for MIMO transmitting according to long-term fadingBreath, makes to compare with other CSI, does not change for a long time above-mentioned order information. AnotherAspect, PMI or CQI reflect the channel status suddenling change by short-period fading, make relatively shortTemporally by its change. Therefore, compare with PMI/CQI and can report for a long time RI,And, compare with RI and can report for a long time PMI and CQI. In addition, according to forThe order of transmitting is determined PMI and CQI, makes to calculate PMI and CQI based on determined RI,Until reach the next RI report period.

As mentioned above, need first to determine order value in the time calculating channel condition information (CSI). CanDetermine order value to consider MIMKO launch scenario. MIMO launching technique can be classifiedFor multiuser MIMO (MU-MIMO) and Single User MIMO (SU-MIMO). IfAssign the space channel that can set up by multiple antennas, this expression to multiple usersMU-MIMO. On the contrary, if assign all space channels to unique user, this expressionSU-MIMO。

MU-MIMO launch scenario can be categorized as: for use non-unitary matrice method,Such as, dirty paper code (DPC), ZF etc.; And, for using the side of unitary pre-coding weightingMethod, such as each user speed at tenth of the twelve Earthly Branches control (PU2RC). These two kinds of methods it is characterized in that fromThe viewpoint of unique user is seen, the precoding weighting of calculating based on limited transmitting order to transmitter report.For example, the many antenna emitters that comprise M transmitting (Tx) antenna can produce maximum 8 skiesBetween channel, and can transmit. Can be assigned to and participate in connecing of MU-MIMO transmittingThe quantity of receiving the space channel of device can be set to M or less. In this case, to eachThe maximum quantity of the space channel that individual user assigns is limited to N(wherein, N < M), make passableN of reception or space channel still less. Suppose and can assign maximum N to transmit space to userChannel, UE selects to be best suited for the order of transmitting. , UE can be from N or order still less (,1 to N order) select optimal order. Can calculate precoding according to selected order addsPower and channel quality information (CQI).

For example, if the quantity of the space channel of assigning to a receiver is limited to 2, receiveDevice can be measured channel shape under the hypothesis that can assign to receiver one or two space channelState information (CSI). In this case, can greatly reduce and must measure and report by received deviceThe quantity of channel condition information. That is, order information is limited to N or 2, makes the number of required bitAmount is reduced to log2 (2) from log2 (N).

Determine PMI quantity according to the code book collection limiting. Suppose and defined from order 1 to orderThe L of N code book collection, and defined from order 1 to the K(of order 2 wherein, K < L)Individual code book collection, has reduced PMI report institute in the case of the maximum order that is limited to N 2The quantity of the feedback information needing.

Must calculate CQI according to each code word (CW). If there are multiple code words(MCW) system comprises maximum 2 CW in order 2 transmitting, should be for order 2 or2 CQI are reported in higher transmitting. If assign maximum 2 space channels, can reportAccuse the CQI(of equal number, 2 CQI).

Transmitter can be considered the quantity of emission layer and calculate CQI. If launched at MCWMiddle use order 2, the second layer is considered in the time calculating the CQI of the CW launching by ground floorDisturb and calculating SINR. Similarly, identify by receiver the space of simultaneously being set up by transmitterThe quantity of channel, the maximum quantity of the space channel that receiver measurement is suitable for being set up by transmitterChannel condition information (CSI). In this case, can increase the precision of CQI. For example,If form maximum 2 space channels by transmitter, and assign each to two usersSpace channel, receiver can calculate under the hypothesis that has interfere with layer in CQI calculatesCQI。

On the other hand, SU-MIMO transmitting is characterized in that a user uses and is set up by transmitterAll space channels. Receiver can (BS) report be suitable for the order information of launching to base station,And receiver can be reported the PMI and the CQI that calculate based on order information. For example, if byThe maximum quantity of the space channel that transmitter is set up is set to N, and receiver is from 1 to NOrder selects to obtain the transmitting order of maximum transmitting efficiency, and selected to the report of e Node BOrder.

Transmitter can be supported SU-MIMO transmitting and MU-MIMO transmitting simultaneously. Can be rightIn independently SU-MIMO and the special control signal of MU-MIMO transmission requests. For example,Can in SU-MIMO transmitting, receive maximum N order, and, for MU-MIMO orderTransmitter can produce maximum N space channel. If receiver is believed maximum N spacesThe useful space channel corresponding with isolated user regarded in road as, can launch for each transmittingThe control signal that pattern is optimized. In this case, transmitter is launched about transmitting mould to receiverThe indication information of formula, makes receiver can identify in advance which emission mode for transmitterSignal transmitting. Thereafter, the control signal of the information that transmitting is suitable for identifying in advance, makes passableReport SU-MIMO transmitting and MU-MIMO transmitting simultaneously.

On the other hand, transmitter not to receiver provide SU-MIMO emission mode andThe Indication message of MU-MIMO emission mode, makes transmitter can allow receiver identification twoAny one of individual emission mode and the corresponding data of decoding. In this case, transmitter canTo notify the quantity of the layer that must be received by current UE to receiver. In this case, UE is notMay identify SU-MIMO pattern and MU-MIMO pattern. Therefore, can use identicalControl signal is supported MIMO transmitting. But, need receiver different to transmitter reportFeedback information, to support SU-MIMO and MU-MIMO. For example,, in order to supportSU-MIMO launches, and can consider the maximum number of the space channel that can produce in transmitterAmount report is best suited for the transmitting order of transmitting. In order to support MU-MIMO transmitting, can considerSelect to the reception of the layer of the limited quantity of seeing from the viewpoint of receiver from limited order and reportBe suitable for the order of transmitting.

Many orders PMI feedback

At the multiple MIMO moulds of system smoothly support for allowing the antenna configuration of supporting expansionIn the feedback method of formula, can use many orders PMI feedback.

For example, can under following hypothesis, determine PMI: receiver is scheduled at SU-MIMODuring order-r, receive r layer from e Node B, and carry out order-rSU-MIMO transmitting. AnotherAspect, although a receiver can receive a layer during MU-MIMO transmitting,In fact transmitter can launch multiple layers.

Many orders PMI feedback can indicate the PMI of order-r for the transmitting of SU-MIMO pattern, andAnd restriction order (for example, order-1 or order-2) is launched for MU-MIMO pattern. For example, shouldWork as attention, can during order-rSU-MIMO transmitting, feed back the order-r based on SU-MIMOPMI. Otherwise, there is the restriction order (for example, order-1 or order-2) based on SU-MIMO hypothesisPMI/CQI can be fed back to MU-MIMO paired. Below detailed description is had limitedThe method of PMI of order (or low-rank).

The limited PMI of low-rank value (order-1 or order-2) is attached to regular order-rPMI, withJust promote the dynamic translation between SU-MIMO pattern and MU-MIMO pattern. In order to prop upBe held in the dynamic SU-MIMO/MU-MIMO conversion from all orders of order-1 to order-8, useMust be supported in the single emission mode of order 1 to 8 on the basis of each subframe dynamicallySU-MIMO and MU-MIMO conversion. In other words, should be in SU-MIMO scheduling andMU-MIMO dispatches in both and uses same UE to feed back (up to order-8PMI/CQI).

Because the unidentified actual transmission pattern of UE or actual transmission order, thus one naturally askTopic is for example to report high order PMI/CQI(, order 3 to 8 as UE) time how at low-rank MU-MIMOFor example, in emission mode (, order-1 or order-2) scheduling UE. A kind of possible solution is to carryFrom the high order PMI(of UE feedback for example get, order 3 is to any one of order 8PMI) front twoRow are dispatched for MU-MIMO. But such " PMI of brachymemma " do not used sometimesDo for example, to suppose the lower best order-1/2PMI calculating at low-rank (, order-1 or order-2). Certainly,Although the PMI of brachymemma may adversely affect MU-MIMO performance, likely use inferiorGood " PMI of brachymemma ". In addition, because be conventionally suitable for MU-MIMO emission modeSituation under the Hypomobility setting (, low-rank adaptation) seen, so once UE can reportAccuse order-rPMI, UE can report order-rPMI continuously for a long time, and without any order-1PMI.Therefore, the benefit of many orders PMI suggestion is to allow UE to supplement best low-rank PMI, makes realityNow for enough CSI precision of order-1 or order-2MU-MIMO pairing. From this visual angle,Many orders PMI also strengthens CSI except promoting dynamic SU-MIMO and MU-MIMO conversionPrecision.

3GPPLTE system can launch maximum 8 layers for SU-MIMO, and can makeTransmit for MU-MIMO with maximum 2 layers. From the viewpoint of receiver, canCarry out restituted signal with identical operation, and irrelevant with SU-MIMO and MU-MIMO.

Receiver provides signal transmitting information (for example, CSI) to transmitter. Conventionally, supposeSU-MMO transmitting is used to CSI report. Conventionally, in the feelings of not considering the interference between communityUnder condition, calculate the CSI based on SU-MIMO, make using the CSI based on SU-MIMO to comeUnder the hypothesis of trial MU-MIMO transmitting, may there is because CQI does not mate performance degradation.Therefore,, in order to improve MU-MIMO emitting performance, can consider to be suitable for for reportThe method of the precoder of MU-MIMO transmitting.

If UE can obtain maximum effect to eNodeB notice during SU-MIMO transmittingThe transmitting order of rate, for example, if calculated and code book index and the CQI of report based on order 8,Feedback information can be used as and be suitable for the information that order 8 is launched, but, above-mentioned feedback letterBreath may be not suitable for MU-MIMO transmitting, in MU-MIMO transmitting, wherein eachThe UE with order-1 and order-2 is re-used and launches. Therefore, should report not only forThe CSI of SU-MIMO and for the CSI of MU-MIMO, to prevent performance degradation.

Conventionally, consider that two kinds of methods are for reporting CSI by receiver to transmitter. These two kindsOne of method is to report the method for CSI by the resource of promising to undertake for the time promising to undertake, andAnd another kind of for report CSI at special time when from transmitter receipt to Indication messageMethod. As the illustrative methods of the time report CSI for promising to undertake, can use at 3GPPIn LTE version 8 by PUCCH report the CQI report information of period method (but,If in the CSI in cycle report time point transmitting PUSCH data, by CSI and data-reusing,And launch multiplexing result). As for when from transmitter receipt to Indication message specificThe method of time report CSI, the uplink transmit control comprising in downlink control channelIn information processed, set up CSI report aperiodic request field, make to report by PUSCHThe result of setting up.

Embodiment 1

The present invention relates to a kind of for the CSI report aperiodic report reporting by PUSCHAccuse the method for CSI information, this CSI information can effectively support SU-MIMO andMU-MIMO. Embodiment 1 can be divided into CSI and the limit of reporting that UE recommends substantially simultaneouslyThe reality of one of the CSI that the embodiment 1-A of order CSI processed and report UE recommend and restriction order CSIExecute routine 1-B.

Embodiment 1-A

Embodiment 1-A relates to for report the UE CSI recommending and the side that limits order CSI simultaneouslyMethod.

Suppose that the order scope that can be received device (, UE) measurement is set to order N, connectsReceive device and calculate order-1 to the CQI of order-N, make it can select can maximize throughput oneIndividual order. But, suppose receiver selection order-M or higher order (for example, M=3), canReport that in addition MU-MIMO launches the information of the order that required ratio order-M is little. In this case,If configurable limit order and the order adaptation in maximum order are possible, ask order designator(RI). If restriction order is set to the restriction order such as order-1 or order-2, can be in nothingNeed only to report PMI and CQI value in the situation of order designator (RI).

For example, if the order that UE recommends is set to M or less (, M=2), only reportThe CSI that UE recommends. For example, if the order that UE recommends is set to M or higher (, M=2),Can not only report the CSI that UE recommends, and report restriction order CSI.

Embodiment 1-B

Embodiment 1-B relates to for only reporting the CSI that UE recommends and limiting one of order CSI'sMethod.

Be set to order-N if can be received the order scope of device measurement, receiver calculates order-1 to order-N CQI make it can select can maximize throughput an order. But,For example, if receiver is selected order M or larger order (, M=3), transmitter can be askedMU-MIMO for example launches required CQI(, the CSI of M or less order). Transmitter canWith request, than being received, device calculates and the information of the order that the order scope of report is little. For this behaviourDo, below will describe multiple embodiment of the present invention in detail.

Embodiment 1-B-1

Can use indicating means, wherein, with the DCI formal definition designator of PDCCH,Make to report the order of being expected by e Node B information.

In UL emission control information, definition is used to indicate the designator of CQI attribute, makes to connectReceive the CQI that device can be reported in the order comprising in the scope of being indicated by transmitter.

In the DCI of 3GPPLTE version 8 form 0, define CQI request field. IfCQI request field is set to 1, UE transmitting CSI. In this case, the CSI launchingInformation comprises order, PMI and CQI. Conventionally be that UE is preferably worth by order Information Selection.

For example,, for example, for thering is system (, the 3GPPLTE version of antenna configuration of expansionThis 10 systems) in the DCI form (for example, DCI format 4) of the new definition of UL transmitting in,The preferred order of flagship report UE in the time of e Node B (or eNB) report CQI. If eNBInstruction order, UE can report CQI in response to the order of eNB configuration. Indicated by eNBOrder can be specified specific order value, can indicate maximum order value, can indicate for maximum order valueIndex, can be the designator of the order value (or predetermined order value) for using promise, orIt can be the designator of the maximum order value for using promise.

Can in DCI form, comprise the order of the order (or restriction order) for using eNB configuration.For example, if activate the CQI request field in the field defining in DCI form, also canThe untapped field of corresponding DCI form is interpreted as to order for using eNB configurationDesignator. Alternatively, above-mentioned designator also can be used as the order for using eNB configurationBe used as the designator of the combination of other field.

For example, can be as the bit field of the DCI format 4 of giving a definition.

[table 19]

In table 19, if start CQI request field, for the second transmission block (TB)MCS and RV field may do not used. In this case, for the MCS of the 2nd TBCan be used to indicate with RV field the order (or restriction order) that eNB configures.

Embodiment 1-B-2

Can be by the method for set up report order scope according to PDCCHDCI form.

Can will be categorized as the DCI for supporting individual layer transmitting for the control information of UL transmittingForm and the DCI form for supporting that multilayer is launched. For example, individual antenna transmitting is that individual layer is sent outPenetrate, for this operation, definition DCI form 0. In addition, although in order to be individual layer transmittingBe also to support specific distribution method, for example can define new DCI form 0A(, DCI form0A). Although be individual layer transmitting, can define and comprise the new of individual layer precoder designatorDCI form (for example, DCI form 0B). In addition, can define for MIMO and launchDCI form, and can for example, for new DCI form (, the DCI of many TB transmitting definitionFormat 4).

Can in each DCI form, define CQI request field. In this case, ifActivate the CQI request field of the DCI form of supporting a transmission block (TB), UE is in limitIn order processed, calculate and report CQI. In addition, if activate the DCI form of supporting multiple transmission blocksCQI request field, UE calculates and reports in the order that can be measured and receive by UECQI。

In other words, if with identical in DCI form " 0 ", " 0A " or " 0B "Mode receive CQI request instruction from the DCI form of supporting single TB, in restriction orderCalculate CQI. If with mode identical in DCI form " 4 " from supporting multiple TB'sDCI form receives CQI solicited message, and UE counts at the order place that can be measured and receive by UECalculate and report CQI.

In this case, restriction order can be established as to the value that is independent of the measurable order of UE.Can be by RRC signaling restriction order, or can limit order and be set to fixed value. ExampleAs, can limit order and be set to maximum order 2.

Embodiment 1-B-3

Can use for setting up the information type of report according to the quantity of transmitting PUSCHMethod.

When the CQI request field of DCI form 0 in 3GPPLTE version 8 is set to 1Time, with k the n+k that subframe is corresponding of the time from receive DCI by PDCCHTime point transmitting PUSCH. The in the situation that of FDD, k is set to 4(k=4).

Can based on receive have activation, for asking the CQI request word of CQI aperiodicThe n frame of the DCI form of section is the CSI that even number or odd number change report according to " n ".For example, if n subframe is even number subframe, can report the CSI of the order of UE recommendation. SeparatelyIf n subframe is odd number, can report the CSI of restriction order outward. Alternatively, ifN subframe is odd number subframe, reports the CSI of the order of UE recommendation. In addition, if n subframeBe even number, can report the CSI of restriction order.

Activating and the DCI that wherein asks the CQI request field for asking CQI aperiodicThe n subframe place corresponding to time of reception of form can be even number or strange according to the value of n+kNumber changes reported CSI. For example, if n+k subframe is even number subframe, can reportAccuse the CSI of the order of UE recommendation. In addition, if n+k subframe is odd number, can report limitThe CSI of order processed. Alternatively, if n+k subframe is odd number subframe, can report that UE pushes awayThe CSI of the order of recommending. In addition, if n+k subframe is odd number subframe, can report restriction orderCSI.

Can by for be effectively supported in SU-MIMO that embodiment 1 proposes andThe CSI method for reporting of MU-MIMO transmitting is applied in the system of supporting the antenna configuration of expandingFor example, in (, the 3GPPLTE-A) emission mode of new definition.

Embodiment 2

Ring higher than use under the condition of restriction order for the order of recommending at UE a kind of description belowThe precoder that should select in the order of UE recommendation selects to be suitable for limiting the precoder of orderMethod.

There is precoder the constituting by N precoding vector of order-N. Can use NSome vectors in individual vector are launched low-rank. Use some vectors of precoder to be claimedFor subset is selected.

Can use many that the subset of the precoder for carrying out from UE to eNB report selectsKind method. For example, can use: 1) for the random method of vector arbitrarily of selecting; 2) useIn the method for selecting subset according to rule predetermined or that promise to undertake; And, 3) for reporting by reportingAccuse the method for the preferred vector of side (, UE). In this case, said method (1) (is usedIn selecting the arbitrarily method of vector) and (2) (for select subset according to the rule of promiseMethod) needn't use other signal. On the other hand, according to preferably vectorial for reporting UEMethod (3), report side (IE) must to report side (eNB) provide subset select information.

Below, description is applicable to above-mentioned for select subset according to the rule of promising to undertakeState rule and the example of method (2).

For example, can use the spy for start sequentially to select row from the first row of precoderSet pattern. The in the situation that of order-1, can select first row. The in the situation that of order-2, canSelect the first and second row.

In another example, can use to be used for considering and to be mapped to transmission block (TB)Layer is selected the another kind rule of subset. Can select be mapped to TB layer in MThe precoder that layer is corresponding. For example, suppose 2 TB(TB1 and TB2) be mapped to 4 layers(layer 1, layer 2, layer 3 and layer 4), a TB(TB1) be mapped to first and second layers(layer 1 and layer 2), and, the 2nd TB(TB2) be mapped to third and fourth layer. ?In this situation, if provide M=1 in precoder subset is selected, can be by with mappedTo subset corresponding to the ground floor of TB1 (layer 1) and with the ground floor (layer that is mapped to TB23) corresponding subset is chosen as two precoders.

The side that can be applied to at the preferred vector of report side report will be described in detail belowThe exemplary Signalling method of method.

For example, can be used as bitmap format and report precoder subset. The in the situation that of order-N,By N the bitmap that bit forms by for showing N vector, can close to eNB reportAnd so on information in the preferred precoder vector of UE.

In another example, if report from precoder subset preferred one toAmount, can be used log₂(N) bit (wherein, N is order) is reported about UE to eNBThe information of one of preferred precoder vector.

If select precoder according to such scheme, can calculate and report and selectThe CQI that precoder is corresponding. For SU-MIMO transmitting, can select order-N precoder,And, can calculate CQI in response to selected precoder. In this case, from order-NPrecoder is selected some precoder vectors, can recalculate corresponding with selected subsetCQI. For example, if selected the precoder for order-4, can prelist by thisCode device calculates the CQI for order-4. In addition, if select two based on order-4 precoderIndividual precoder vector, the order-2CQI that can calculate.

Below detailed description is applicable to the various exemplary feedback side that above-mentioned precoder is selectedMethod.

According to the first feedback method, can use for feedback " RI – PMI1 – CQI1 – PMI2– CQI2 " method. In the first feedback method, RI is and PMI1(or precoder 1)Corresponding order information, and calculate CQI1 based on PMI1. PMI1 selects from PMI1Precoder, and, calculate CQI2 based on PMI2. In this case, can be onceOr launch in multiple times each of PMI1, PMI2, CQI1 and CQI2.

According to the second feedback method, can use for feedback " RI – PMI1 – CQI1 –CQI2 " method. In the second feedback method, RI is and PMI1(or precoder 1) rightThe order information of answering, and calculate CQI1 based on PMI1. Can be based on PMI2(or precodingDevice 2) calculate CQI2. PMI2 is the precoder of selecting from PMI1. If by holdingPromise rule is selected PMI2, does not report PMI2. By this way, can one or manyEach of ground transmitting PMI1, CQI1 and CQI2.

According to the 3rd feedback method, can use for feedback " RI – PMI1 – CQI1 – PSI(precoder is selected designator) – CQI2 " method. In the 3rd feedback method, RI isWith PMI1(or precoder 1) corresponding order information, and calculate CQI1 based on PMI1.PMI2(or precoder 2) be the precoder of selecting from PMI1, and can reportWhich value PSI to indicate be selected as PMI2. In this case, can send out on one or many groundPenetrate each of PMI1, CQI1 and CQI2.

In the case of the above-mentioned feedback method of application, can be according to the channel of report (for example,PUSCH or PUCCH) report feedback information simultaneously, or can be at different circulation reportsAccuse feedback information. For example, in the case of by the feedback report of PUSCH, can pass through oneIndividual channel is reported RI, PMI and CQI. If report is selected as some subsets of PMI1PMI2, can report PMI2 and CQI2 by a channel only simultaneously. Alternatively,In the case of by the feedback report of PUCCH, can different circulation place report RI,PMI and CQI. If report is selected as the PMI2 of some subsets of PMI1 as mentioned above,Also can be at different circulation report PMI2 and CQI2.

Embodiment 3

Anti-by describing in detail for determining in the time that transmitting is used for limiting the precoder information of order belowThe method that put the launch time of feedforward information.

Conventionally, see and use low-rank precoder to realize MU-MIMO from a user's viewpointTransmitting, and preferably, conventionally multiplexing have with transmitting the user that low spatial is relevant. EvenIn the situation that MU-MIMO launches, UE adopts SU-MIMO, and not at MU-MIMOBetween transmitting and SU-MIMO transmitting, distinguish, and then determine and be reported in it and expect that maximum gulps downThe order value of the amount of telling. At the sum of ranks precoder of selecting and report is recommended in response to the UE of corresponding orderCondition under, can calculate and report high order precoder and the CQI being associated. High when reportingWhen order precoder, the subset configuration low-rank precoder of precoder that can operation report withFor MU-MIMO transmitting, or, can use for report low-rank precoder in additionMethod.

First,, will describe in detail for allowing eNB to select from the precoder of UE reportSubset is to carry out the method for MU-MIMO transmitting. If depend on the pre-of order that UE recommendsEncoder subset, for MU-MIMO transmitting, needs CQI to carry out the MU-MIMO for eNBTransmitting. The CQI's calculating because eNB receives the precoder of the order of recommending based on UEReport information, this CQI can be used as MU-MIMOCQI. But, based on UEThe channel status of the order precoder of recommending and the CQI that calculates can with use corresponding precodingThe required channel status difference of data of device subset transmitting. Therefore, therein eNB use based onThe CQI that the order precoder that UE recommends calculates is used as in the situation of MU-MIMOCQI,CQI does not mate and may occur. Preferably, the CQI that report is calculated based on precoder subsetTo improve MU-MIMO handling capacity.

Secondly, below use description to allow UE to report in addition the method for low-rank precoder.In the time of report low-rank precoder, preferably side by side report based on prelisting with low-rank precoderThe CQI that code device calculates.

Distribute to carry out the PUCCH of reporting channel information with traditional scheme from eNB to UEResource is limited, and, can report the precoder of order that UE recommends by PUCCHWith the CQI being associated. Therefore, in order to report precoder subset and the CQI being associated or to beReport restriction order precoder and the CQI that is associated, need one to be used for redefining like thisThe report time point of other feedback information and/or the method for resource.

Embodiment 3-A

By the method for describing in detail for setting up skew, in this skew place, report is based on limit belowThe precoder of order processed and CQI.

The in the situation that of cycle PUCCH feedback report, definition is for RI and PMI/CQI transmittingTime point. Conventionally, in different subframe place report sum of ranks PMI/CQI information. Specifically,At the circulation place report RI longer than PMI/CQI. If report order, in response to corresponding transmittingThe PMI/CQI information corresponding with the order of previously reporting is reported in circulation, until arrive next orderReport time.

If report as mentioned above higher rank, need to report low-rank PMI and the CQI being associatedOr the subset of high value precoder and the CQI being associated. Low-rank precoder/CQI information canTo be called as the PMI/CQI information that limits order.

The time point of report restriction order PMI/CQI can be another of report higher rank PMI/CQIThe some parts of individual timing. , can be by the high order PMI/CQI report between the order report periodThe special time of accusing in timing is worked as the report timing that is restricted order PMI/CQI. Can be than UEThe long circulation report of report timing of the order PMI/CQI recommending limits order PMI/CQI(, canDo not report continually restriction order PMI/CQI with the order PMI/CQI recommending than UE), or canSentence predetermined migration with the order PMI/CQI report time point of recommending at UE and report restriction orderPMI/CQI. The order PMI/CQI that can recommend than UE especially, puts lately and report launch timeThe skew of restriction order PMI/CQI point launch time.

On the other hand, can be to push away based on UE for the timing slip of the subframe of order information transmittingThe identical subframe of the order PMI/CQI subframe of recommending, or can be before being positioned at above-mentioned subframeSubframe place is launched. In order to prevent limiting order PMI/CQI transmitting and launch the son of order information at itFrame conflict (, in order to prevent at the subframe place transmitting restriction order PMI/CQI identical with order information),Can than the reference subframe of order PMI/CQI of recommending at its transmitting UE late report restriction orderPMI/CQI. In addition, can be established for limiting the skew of putting the launch time of order PMI/CQIBe set to just (or negative) integer except " 0 ".

Figure 22 and 23 illustrates the example of restriction order PMI/CQI transmitting timing and skew.

Below with reference to Figure 22 and 23, described showing of restriction order PMI/CQI transmitting timing and skewExample. In Figure 22 and 23, N_sTime slot index, and can be 0,1 ..., Ns. ,At the radio frame being formed by 10 subframes shown in Figure 22 and 23, and,It is subframe index.

In Figure 22, the CQI/PMI of the order of recommending based on UE in the transmitting of Np interval,Integral multiple (Np × the M of the CQI/PMI circulation of the order of recommending based on UE_RI) interval transmittingRI, and, predetermined migration before CQI/PMI point launch time of order that is positioned at UE recommendation（N_offset,RI) time point transmitting RI. As described in the above-described embodiments, UE can be positioned atPredetermined migration (N after CQI/PMI point launch time of the order of recommending_offset,CQI) time point send outPenetrate restriction order PMI/CQI, and can use the order CQI/PMI transmitting circulation of recommending than UERestriction order PMI/CQI is launched in long circulation.

Can be as can be seen from Figure 23, the order that WBCQI/PMI and SBCQI are recommended as UECQI/PMI launches. WBCQI/PMI and SBCQI are alternately launched in interval with Np,And transmitting circulation that can WBCQI/PMI is set to (H × Np). Can push away at UEThe interval of the integral multiple of the WBCQI/PMI circulation of the order of recommending is (, at (H × Np × M_RI)Interval) transmitting RI. Predetermined before CQI/PMI point launch time of order that is positioned at UE recommendationSkew (N_offset,RI) time point transmitting RI. As in the above-described embodiments previously as described in, canPredetermined migration (N after CQI/PMI point launch time of order that is positioned at UE recommendation_offset,CQI）Time point place transmitting restriction order PMI/CQI, and can use the order of recommending than UERestriction order PMI/CQI is launched in the long circulation of CQI/PMI transmitting circulation.

The example of the feedback model that limits order PMI/CQI will be described in detail below.

According to embodiment 3-A-1, the feedback model of restriction order PMI/CQI can be recommended based on UEThe feedback model of order PMI/CQI. For example,, if the feedback of the order PMI/CQI that UE recommendsPattern is the pattern for launching WBPMI and WBCQI, also can be by restriction orderPMI/CQI is as WBPMI and WBCQI transmitting. Alternatively, if UE recommendThe feedback model of order PMI/CQI is the pattern for launching WBPMI and SBCQI, alsoRestriction order PMI/CQI can be launched as WBPMI and SBCQI.

In addition, if to report SBCQI with mode identical in band circulation, can useA circulation, wherein, report WBCQI, and report is for each portions of bandwidth (BP)All SBCQI. Can report therein the WBCQI of each BP and of SBCQICycle period report restriction order PMI/CQI. , can will in RI report circulation, there is oneOr the circulation of the band in multiple cycles reports that at least one circulation in the period is set to limit orderThe report period of PMI/CQI.

W1 andW2 can be made up of various code books. Therefore, eNB can receive the difference feedback of precoderThe report information of designator (W1 and W2), and then select whole precoder. CanDifferent information (W1 and W2) in different time point place reports for precoder. For example,Can report W1 long-term, and can report W2 in short-term. When at long-term report W1,Can report W1 together with order information. Alternatively, can report W1 and W1 simultaneously. ,In the situation that using many granularities precoder, can set up some launch time of feedback information,As shown in table 20 below.

[table 20]

	T1	T2
			Pattern (1)	Order+W1(broadband)	W2(broadband)+CQI(broadband)
Pattern (2)	Order	W1(broadband)+W2(broadband)+CQI(broadband)

Can find out from the pattern of table 20 (1), at one time point (T1) transmitting orderInformation (RI) and WBW1, and, can be in the random time T2 of hysteresis T1 time transmittingWBW2 and WBCQI. Alternatively, can find out from pattern (2), can be in the timeT1 transmitting order information (Ri), and, can be in the random time T2 of hysteresis T1 time transmittingWBW1, WBW2 and WBCQI.

By this way, the designator for precoder in identical or different time point reportUnder the condition of (W1 and W1), can feed back restriction order PMI/CQI. If report restriction orderPMI/CQI, can select and feed back the W1 and the W2 that are suitable for limiting order. In addition, canThe CQI of feedback based on selected W1 and W2 calculating. In this case, can be for the moment sameBetween some place (, at a subframe place) report W1, W2 and CQI.

The restriction order being included under many granularities precoder is described below with reference to Figure 25 and 26The feedback method of PMI/CQI.

In Figure 25, launch RI and PMI1(at a time point place, WBW1 simultaneously),And launch WBPMI2(, WBW2 at time point place subsequently) and WBCQI. ?In this situation, PMI1, PMI2 and CQI can be that the order of recommending according to UE is selected and calculatesFeedback information. In addition, can be after being positioned at order CQI/PMI launch time that UE recommendsPredetermined migration (N_offset，CQI) time point place transmitting restriction order PMI/CQI. In Figure 25,WithPMI1, PMI2 and the CQI of the time point place transmitting restriction order of=2 correspondences.

In Figure 26, after transmitting RI, launch WBPMI1(, WBW1 simultaneously),WBPMI2(, WBW2) and WBCQI. The PMI1 that launches in this case,,PMI2 and CQI can be the order selection of recommending according to UE and the feedback information calculating. In addition,Predetermined migration (N after order CQI/PMI point launch time of UE recommendation can be positioned at_offset,CQI）Time point place transmitting restriction order PMI/CQI. In Figure 26, withCorrespondingPMI1, PMI2 and the CQI of time point place transmitting restriction order.

Embodiment 3-B-2

Embodiment 3-B-2 relates to the feedback method under the condition of many granularities of definition precoder.

If report many granularities precoder designator (, W1 and W2) to eNB, canIndicate different feedback models to use precoder type instruction (PTI) bit.

In a feedback model, at different transmitting R1, the W1 of subframe place and W2/CQI,And W1, W2 and CQI are established as to WB information. In other feedback model, sameThe report W2 of subframe place and CQI, W2/CQI frequency granularity can be WB according to the subframe of reportOr SB. Feedback model that, can definition list 21.

[table 21]

	T1	T2	T3
				Pattern (1)	PTI(0)+order	W1(broadband)	W2(broadband)+CQI(broadband)
Pattern (2)	PTI(1)+order	W2(broadband)+CQI(broadband)	W2(subband)+CQI(subband)

In table 21, if PTI is set to zero (0), at time point T1 transmitting RI,And put at any time T2 place transmitting WBW1. Thereafter, can be according to for WBW2Put at any time T3 with the pattern of WBCQI transmitting and carry out feedback function. In table 21,If PTI is set to 1, at time point T1 place transmitting RI, and can be then arbitrarilyTime point T2 transmitting WBW1 and WBCQI. Thereafter, can be according to for SBW2 and SBThe pattern of CQI transmitting is put at any time T3 place and is carried out feedback function.

Can be according to the feedback of order information (RI) circulate deterministic model (1) or pattern (2).After by PTI deterministic model (1) or pattern (2), can circulate to report in response to CQIAccuse WBW1, WBW2 and WBCQI(referring to pattern (1)), or can be in response toCQI circulates to report that WBW2/WBCQI and SBW2/SBCQI(are referring to pattern (2)).The reference of the circulation of report can be set to some launch time of WBW2 and WBCQI. ItsThe transmitting timing of its feedback information can be confirmed as launching regularly for WBW2/WBCQISkew.

In the feedback method of this embodiment, below will describe in detail for setting up and be used for like thisThe circulation of WBW1 feedback and the method for skew.

According to first method, can be with the interval of the special time longer than PTI/RI transmitting circulationSet up WBW1 transmitting circulation. , can not set up continually than PTI/RI transmitting circulationWBW1 launches circulation. In addition, WBW1 circulation can be sending out of WBW2 and WBCQIPenetrate the integral multiple of circulation. In addition, with reference to timing (, WBW1 transmitting timing can be established asThe transmitting subframe of WBW2 and WBCQI) deviant.

According to second method, with reference to timing (, WBW1 transmitting timing can be established asThe transmitting subframe of WBW2 and WBCQI) deviant. In addition, if PPTI/RI feedbackThe PTI of information is set to particular value (0 or 1), can after PTI/RI transmitting, send out immediatelyPenetrate WBW1.

In the feedback method of this embodiment, below detailed description is used for feeding back restriction orderThe method of PMI/CQI. Above-mentioned WBW1, WBW2, WBCQI, SBW2 and SBCQIThe feedback information that the order that is used as recommending according to UE is selected and calculated, or can further launchRestriction order PMI/CQI.

If the PTI reporting together with RI is set to 0, can be by WBPMI and WBCQI is reported as restriction order PMI/CQI. Can put at one time report restriction order WBW1,WBW2 and WBCQI. Report therein (WBW2+WBCQI) of the order of UE recommendationSubframe in some subframes in, can report simultaneously restriction order WBW1, WBW2 andWBCQI。

Alternatively, if the PTI reporting is set to 1, can report restriction together with RIOrder PMI/CQI. In this case, can report restriction order by two kinds of methods belowPMI/CQI。

In first method, only can be by WBW1, WBW2 and the WBCQI of restriction orderBe reported as restriction order PMI/CQI.

In the second approach, can be at WBW1, the WB of a subframe place report restriction orderW2 and WBCQI, and, can be at the SBW1 of different subframe place report restriction order andSBCQI. Can set up according to the band circulation report period point launch time of above-mentioned factor.

Embodiment 4

Embodiment 4 discloses a kind of for determining to construct the different precoders of whole precoderThe method of the amount of bits of index.

Table 11 illustrates for making 8 the Tx antennas that have in 3GPPLTE system to 18BS(or eNB) can report the code book of CSI. At table 11 to the CSI shown in 18Report code book can decide code book element according to two kinds of feedback reports. Although table 11 is to 18Two feedback reports are expressed as to i1 and i2, but i1 and i2 correspond respectively to a precoderIndex W1(or PMI1) and another precoder index W2(or PMI2). Two reportsAnnouncement value can have different time points, and can be established to have different frequency granularity.For data transmission, the quantity of the Constitution Elements of code book (# of element) can push away according to UERecommend the quantity of order and there is different value, as shown in table 22 below.

[table 22]

In table 2, i1 can be defined the element according to order with 16,4 or 1, and i2 canBe defined according to order have 16,8 or 1 also have element. For feedback, can be by 0Represent i1 to 4 bits, and can represent i2 by 0 to 4 bit. Can lead toCross the maximum quantity that table 23 below represents to express according to order the bit of i1 and i2.

[table 23]

Order	1	2	3	4	5	6	7	8
									For maximum bits of i1	4	4	2	2	2	2	2	0
For maximum bits of i2	4	4	4	3	0	0	0	0

Because be defined to report that the control channel of feedback information holds quantitative limitation, so can limitSystem can represent for the i1 of CSI report and the bit of i2. , must transmitting i1 and i2 valueWith report CSI. If for the designator of i1 value and/or can be with for the designator of i2 valueRI or CQI launch together, can realize and be reported in traditional 3GPPLTE version 8 or versionThe similar error rate of error rate of the RI of definition or the channel of CQI in basis 9, and simultaneously, canWith in transmitting feedback information as required.

In transmitting simultaneously together with RI or CQI for the designator of i1 value and/or for i2 valueIn the situation of designator, for example, can report RI by a subframe, and can pass throughAnother subframe is reported for the designator of i1 value, for designator and the CQI of i2 value simultaneously.In another example, report designator and the RI for i1 by a subframe simultaneously, andAnd can launch designator and the CQI for i2 by another subframe simultaneously.

Traditional 3GPPLTE version 8 or version 9 are supposed sending out for maximum 2 bits of RIPenetrate. In the case of the RI transmitting by PUCCH, can use with at ACK/NACKIdentical Compilation Method in transmitting. In addition, suppose that maximum 11 bits of transmitting are with report CQI/PMI,Make to use can support maximum 13 bits Reed-Muller (Reed-Muller) (RM)Code is carried out compiling.

For example, if system (, the 3GPPLTE version 10 of the antenna structure of expansion is supported in suppositionSystem) report i1, i2 and CQI(i1/i2/CQI simultaneously), can for order-1 or order-2Need maximum 15(=4+4+7) individual bit. In order to launch 15 bits, can use for expandingOpen up the Compilation Method of traditional RM code, or can report control with traditional convolutional codeSignal processed. In addition, in order to realize the level identical with the maximum bits that define in legacy system,Can use where necessary for reducing the big or small method for the indicator bit of i1 and i2.

Table 24 illustrates for report i1, i2 and CQI(i1/i2/CQI simultaneously) required bitQuantity. If the indicator bit for i1 and i2 is set to 0～4, in table 24Be illustrated in the quantity of the bit of launching in a subframe. In addition, according to order, for i1 or i2The quantity of indicator bit can be complete or collected works or subset. For example, if i1 indicator bit establishedBe set to 4 and i2 indicator bit be set to 4, can use all complete or collected works of code bookLaunch order-1 and order-2. Alternatively, 2 bits are for i1 or (W1) and 4 thereinBit is for i2(or W2) situation under, can in order-1 or order-2, use the subset of i1,The complete or collected works of i2 can be used, and all complete or collected works of i1 and i2 can be in order-3, used. ?In table 24, F can represent complete or collected works, and S can represent subset. In addition, every with table 21An expression formula (F/F, F/S, S/F or S/S) explicitly, be positioned at special symbol (/) itBefore number represent for the bit of i1, and be positioned at symbol (/) another number afterwards and represent to useIn the bit of i2.

[table 24]

In order to apply traditional Compilation Method or acquisition and traditional feedback letter to the transmitting of PUCCH feedbackThe similar error rate of error rate in road can be launched 13 bits or still less in a subframe. ?In this situation, in the time using the subset that only comprises the code book element of quantity very little, accordinglyIn subset, comprise the probability of the code book element for expressing the CSI that is suitable for actual channel stateReduce gradually, cause launching reducing of handling capacity. Therefore, must reduce the quantity of feedback bits,And must use the subset of proper level.

For example, for order-1 and order-2, can ask maximum 4 for each in i1 and i2Individual bit. Can use where necessary wherein " (for the bit of i1 designator/indicate for i2The bit of symbol) " be set to (4/3), (4/2), (3/3), (3/2), (2/3),Etc. (2/2) subset of any one index in.

In addition, can make according to order complete or collected works or the subset of index of reference. For example, for realize withThe corresponding level of maximum 11 bits, " 2 bit/2 bit " can be for i1 and i2(i1/i2).In this case, can use " 2 bit/2 bit " at order 1 to 4 place, can be in order 5 to 7Place is used " 2 bit/0 bit ", and can use " 0 bit/0 bit " at order 8 places. Can replaceSelection of land, in order to realize the level corresponding with maximum 13 bits, " 3 bit/2 bit " can be usedIn i1 and i2(i1/i2). In this case, can use at order 1 and 2 places " 3 bit/2 ratiosSpecial ", can use at order-3 place " 2 bit/4 bit ", can use at order-4 place " 2 bit/3Bit ", can use " 2 bit/0 bit " at order 5 to 7 places, and can make at order-8 placeWith " 0 bit/0 bit ". Table 22 illustrates for each order and can be used in i1 and i2(i1/i2)Exemplary amount of bits.

[table 25]

Table 26 illustrates the preferred compositions of the quantity of the bit of the i1/i2 of table 25.

[table 26]

Table 27 illustrates simultaneously when launch RI and i1 index in a subframe time or works as at anotherRequired bit while simultaneously launching i2 index and CQI in subframe.

[table 27]

If according to the maximum order that can receive at UE place or next from the maximum order of eNB transmittingDetermine the maximum quantity of the order of being reported by UE, can be identified for the bit of order instruction. IfCombine and launch RI and i1 simultaneously, for the maximum quantity that feeds back required bit can beThe minimum number of 7(=3+4) individual bit, and bit can be 5(=1+4) individual bit.

Order information, substantially for selecting/calculate other feedback information, makes to need robust and launchesOrder information. Therefore, preferably, reduce as much as possible and launching corresponding subframe with orderIn the quantity of the bit that comprises. For such transmitting, can use where necessary for reducingThe method of the quantity of the bit of i1 designator. Consider above-mentioned condition, table 28 exemplarily illustratesCan be used in i1 and i2(i1/i2 for each order) amount of bits.

[table 28]

In the case of the subset of i1/i2 designator is set, for example, can establish according to preferred rankMeter i1 and i2 subset are to have different sizes. In another example, i1 and i2 subset canBe designed to the classification according to UE and there is different sizes. Can classify according to UE abilityUE classification.

Embodiment 5

To describe in detail according to of the present invention for passing through different precoder indexes below(i1/i2) method of code book subset is set.

Table 29 illustrates and is suitable at another of the code book of the order shown in table 11-1CSI reportIndividual example. Can be based on 4TxDFT vector (v_m) configure order-1 code word, and canBy 4TxDFT vector (v_m) and phase place () combination represent order-1 code word. AsFruit is defined as 0 to 15 and i2 index is defined as to 0 to 15 by i1 index, can pass throughThere is 32PSK(phase-shift keying (PSK)) v of phase place_mWith there is the orthogonal PSK of QPSK() phase placeThe two carrys out configuration code originally. In this case, can between the continuity index of i1 value, repeatIdentical element.

[table 29]

Therefore,, for configuration code subset originally, can consider: for limit structure v_mToAmount orThe method of phase place of DFT matrix of phase place; And, for using an i1 valueIn this yuan of different code at different i1 indexes place of the code book element that comprises usually construct i1 valueMethod. By this way, can construct subset of codewords.

According to whether using i1 or i2 subset, can determine v_mDFT vector sumPhase place.For example, suppose in order to indicate i1 value, can use 3 bits, and can use 8 idolsNumber index (0,2,4,6,8,10,12,14). Also supposition, in order to indicate i1 value, canTo use 3 bits, and can use 8 indexes (0,1,2,3,8,9,10,11). Under these hypothesis, can configure and have for v_mValue 16PSK phase place and for phasePosition () the 4TxDFT vector of QPSK.

As mentioned above, in the time determining for the indication bit of i1 value with for the indication bit of i2 value,Can represent for constructing v by table 30 below_mA phase place of the 4TxDFT vector of valueWith for construct according to the combination of index that is suitable for each bit phase place () anotherPhase place.

[table 30]

Table 31 illustrates and is suitable at another of the code book of the order shown in table 12-2CSI reportIndividual example. In the report of order-2CSI, 16 are defined for each in i1 and i2 valueIndex (0 to 15).

[table 31]

When determine to be used for the indication bit of i value and the finger for i2 value in the configuration of code book subsetWhile showing bit, can represent to construct v by table 30_mPhase place and the root of the 4TxDFT vector of valueAccording to the combination of index that is suitable for each bitPhase place.

Determine v according to whether by i1 or i2 subset_mDFT vector sumPhase place. AsShown in table 31, in the time determining for the indication bit of i1 value with for the indication bit of i2 value,Can represent for constructing v by table 32 below_mA phase place of the 4TxDFT vector of valueWith for construct according to the combination of index that is suitable for each bit phase place () anotherIndividual phase place.

[table 32]

Be similar to above-mentioned scheme, can be to the generation that is suitable for order-3 to order-8 of table 13 to 18The method of the subset of the code book that code book application is represented by " i1/i2 " for selection.

For example, the i2 value of order-3 code book of table 13 can be by 16 elements (0～15) structureBecome, and can be made up of matrix, this matrix produces three orthogonal beams with two vectors.Can configure with two vectors order-3 code book of Four types.

For example, if i2 forms by 0,1,2 and 3, can use four order-3 code books(type-A, type-B, type-C and type-D), and will describe below that it is detailed in detailExplanation.

The in the situation that of type-A, first row is by having (+) homophase justForm secondRow are by having negative (-) homophaseForm, and the 3rd row are by having negative (-) homophaseForm. [A: first row (has (+) homophase), secondary series (has (-) homophase's) and the 3rd row (there is (-) homophase）。

The in the situation that of type-B, first row is by having (+) homophase justForm, theTwo row are by having negative (-) homophaseForm, and the 3rd row are by having negative (-) homophaseForm. [B: first row (has (+) homophase), secondary series (has (-)Homophase), the 3rd row (have (-) homophase）。

The in the situation that of type-C, first row is by having (+) homophase justForm secondRow are by having (+) homophase justForm, and the 3rd row are by having negative (-) homophaseForm. [C: first row (has (+) homophase), secondary series (has (+) homophase's), the 3rd row (have (-) homophase）。The in the situation that of type-D, first row is by having (+) homophase justForm, theTwo row are by having (+) homophase justForm, and the 3rd row are by having negative (-) homophaseForm. [D: first row (has (+) homophase), secondary series (has (+)Homophase), the 3rd row (have (-) homophase）。In above-mentioned example, two vectors that use in code book are vectorsSeparatelyA vector. The in the situation that of i2=0 and i2=2,Vector is for first row. At i2=1In the situation of i2=3,Vector is for first row. In addition, in the feelings of i2=0 and i2=1Under condition, be listed as two different vectors of application (, to second and the 3rdWithVector),Make between two row, to realize orthogonality. On the other hand, the in the situation that of i2=2 and i2=3,Can be listed as a vector of application (, to second and the 3rdOrVector), make passableUse different in-phase component (, (+) and (-) homophase) to obtain orthogonality.

When by a kind of situation of (i2=0,1,2,3) at the code book place, order-3 at table 13 withIn the time that the situation of (i2=4,5,6,7) at code book place, order-3 of table 13 is made comparisons, canThe formation vector of recognizing code book differs from one another. , with the situation of (i2=0,1,2,3)Explicitly, useWithVector. Another kind of situation with (i2=4,5,6,7)Explicitly, useWithVector.

By the above-mentioned type (type-A, type-B, type-C and type-D), also can lead toCross table 33 below and represent that order-3 code book produces matrix.

[table 33]

As the big or small method of indicating required bit for reducing code book, can use sonSampling application.

For example, 2 indication bit that form order-3 code book can be reduced to institute in table 34The exemplary bit showing.

[table 34]

I1	I2	Total bit size
			2	4	6
1	4	5
			2	3	5
0	4	4
			1	3	4
2	2	4

For the whole bit size that is allowed for code book instruction is made up of 4 bits, canUse where necessary three kinds of schemes (, i1+i2=0+4,1+3,2+2). From these three kinds of schemesAmong, if " i1 " is made up of 0 bit, that is, if " i1 " is made up of an element, wave beamResolution deteriorates, causes the reduction of performance or handling capacity. Next,, detailed description is removedUse the residue scheme outside the scheme of " i1 " that formed by 0 bit.

First, below use description to construct under the following conditions the various of i1 subset and i2 subsetMethod: assign a bit (1 bit) to " i1 ", and assign 3 bits to " i2 ".

In the case of from select among all indexes of i1 and i2/use subset, can basisThe element of the code book of having selected which index and produce is changed to another element, makes excellentChoosing, suitably selects index with structure high-performance code book.

If i1 is made up of 1 bit, can from several indexes of the i1 that formed by 1 bit (0,1,2,3) among, select two indexes. According to selecting among (0,1,2, the 3) index from i1The vectorial quantity of selecting which index and can be used as the Constitution Elements of code book is set to 12Or 16. For example, if can select (0,1) among the index of i1 (0,1,2,3),Can use12 vectors (m=0,2,4,6,8,10,12,14,16,18,20,22). In another example, if can be from the index of i1 (0,1,2,3)Among select (0,2), can use（m=0、2、4、6、8、10、12、14,16,18,20,22,24,26,28,30) 16 vectors. , if i1 quiltBe set to (0,1) [, i1=(0,1)], can be in i1=0 and i1=1 everyAn application copies or overlapping vector. If i1 be set to (0,2) [, i1=(0,2)], can apply different vectors to each in i1=0 and i1=2. Therefore, preferred, can use i1=(0,2 from the viewpoint of beam resolution).

On the other hand, if i2 is assigned 3 bits, can be from from 0 to 15 16Among i2 index, select 8 indexes. For selecting the first method of 8 indexes to be designed to choosingSelect the i2 index that comprises various vectors, to increase beam resolution. Be used for selecting 8 indexesThe second method execution index select to comprise all Four types (types of structure order-3 element-A, type-B, type-C, type-D).

For example, the first method from four i2 index-group [(0,1,2,3), (4,5,6,7),(8,9,10,11), (12,13,14,15)] among select two groups, make it passableUse 8 indexes. For example, if by 8 indexes [(0,2), (4,6), (8,10),(12,14)] be chosen as i2 index, can produce based on type-A with 8 vectorsAnd the order-3 code book element of type-C. In another example, if by 8 indexes [(1,3), (5,7), (9,11), (13,15)] be chosen as i2 index, can use8 vectors produce the order-3 code book element based on type-B and type-D.

For example, the second method can from four groups [(0,1,2,3), (4,5,6,7),(8,9,10,11), (12,13,14,15)] among select two groups, make it canTo use 8 indexes. In the case of the matrix of structure order-3 code book, can be by+1 and-1As in-phase component. In addition, existence can form 8 TxDFT vectors by in-phase componentVector. For example, if in the case of be numbered 0,8,16 and 24 vectorial by (+1)As homophase element, can form 8 TxDFT vectors. In another example, ifIn the case of be numbered 4,14,20 and 28 vectorial by (1) as homophase element,Can form 8 TxDFT vectors. Consider the antenna structure of co-polarization, 8 TxDFTThe use of vector can realize high-throughput or performance.

Because the in-phase component using in the matrix of structure order-3 code book is set to (+1)(1), preferably, becomes to comprise by i2 index selection to use above-mentioned in-phase componentForm the 0th, 8,16,4,14,20 and 28 vectors of 8TxDFT vector. For example, canSo that (0,1,2,3) and (8,9,10,11) are chosen as to i2 index.

Next, therein 2 bits are assigned to " i1 ", and 2 bits are assigned to " i2 "In situation, below will describe in detail for constructing the whole bag of tricks of i2 subset. Because i1 comprises volumeNumber be 0,1,2 and 3 index, so can represent all indexes by 2 bits.

For example, for when by i2 index 0 to 15 be categorized as four groups [(0,1,2,3), (4,5,6,7), (8,9,10,11) and (12,13,14,15)] time select i2 ropeThe subset of drawing is selected one group among four groups, makes to use four elements of corresponding group.Among each of four groups, select an index, make to configure four elements. Can alternativeGround is selected two groups, and can among selected group, be selected two ropes among four groupsDraw, make to configure four elements.

Wherein each can optionally use the Four types of structure order-3 code book elementThe quantity of the situation of two in (type-A, type-B, type-C and type-D) is set upBe 6, corresponding situation be (A, B), (A, C), (A, D), (B, C),(B, D) and (C, D).

In addition, wherein each can optionally use the feelings of two in four groups of i2 indexThe quantity of condition is set to 6. If the most front vector among i2 index-group refers to accordinglyGroup, can represent corresponding group by being numbered 0,4,8 and 12 group. Wherein eachThe corresponding situation of two in four groups of individual selection be (0,4), (0,8), (0,12),(4,8), (4,12) and (8,12).

As six kinds of situations of the method about for constructing order-3 code book element and about forSelect the combination of six kinds of situations of the method for Vector Groups, realize for structure 36 i2 indexes altogetherThe method of subset.

According to above-mentioned example, assign 1 ratio to " i1 " explicitly with order-3 code book thereinSpy also assigns 3 bits to " i2 ", and assigns 2 bits and assign 2 to " i2 " to " i1 "In the situation of individual bit, can represent to construct showing of i2 and i2 subset by table 35 belowExample.

[table 35]

Even if configure therein in the situation of order-4 code book, can use sub sampling below.For example, can as shown in table 36 below, reduce to construct two of above-mentioned order-3 code bookDesignator (i1 and i2).

[table 36]

I1	I2	Total bit size
			2	3	5
1	3	4
			2	2	2

With order-4 code book explicitly, can with order-3 code book for from above-mentioned amongSelect the similar mode of scheme of subset to select the subset of i1 and i2 index. For the side illustratingJust with clear, can omit identical part at this.

In the code book of order-4, assigning 1 bit to " i1 " and assigning 3 bits to " i2 "Situation under, and assigning 2 bits to " i1 " and assigning another of 2 bits to " i2 "In kind of situation, can represent for constructing i2 subset and i2 subset by table 37 belowExample.

[table 37]

On the other hand, can report PUSCH by selected code book subset. For example,As shown at PUSCH Report mode 1-2 for reporting the PMI for each subbandPattern during, i1 and i2 subset can be for reducing PMI feedback overhead. In this case,With " i1 " explicitly, can be at an index of WB place report, and with " i2 " explicitly,Can report the index for each SB.

In addition, 3GPPLTE version 10 systems can be used for reporting as new PUSCHThe SBCQI of Report mode and the AD HOC of SBPMI. Even in above-mentioned Report mode,Can reduce by code book subset the quantity of the report bit that is used to indicate code book. At thisIn situation, with " i1 " explicitly, can be at an index of WB place report, and with " i2 " phaseAssociated ground, can report the index for each SB.

Embodiment 6

In embodiment 6, define for reporting periodically multi-control information by PUCCHPattern, and will describe in detail for determining that to be applicable to the transmitting of control information report excellent belowThe first method of level.

As previously described in table 5, can according to PUCCH Report mode (pattern 1-0,1-1,2-0 and 2-1) feed back periodically various control informations (RI, PMI, CQI). Can pass throughHigh level is semi-statically set up the periodic feedback of UE. Can whether be single antenna according to DL transmittingTransmitting, transmit diversity transmitting, Closed-Loop Spatial Multiplexing (SM) transmitting or double-deck transmitting etc. come correctGround is to corresponding DL transmitting application PUCCH Report mode. In addition, can PUCCH will be used forThe CQI/PMI/RI feedback kind of Report mode is categorized as Class1, type 2, type 3 and classType 4. Class1 is the CQI feedback for the subband of UE selection. Type 2 is WBCQIFeedback and WBPMI feedback. Type 3 is RI feedbacks. Type 4 is WBCQI feedbacks.

On the other hand, defined can be at it for traditional 3GPPLTE version 8 or version 9In various control informations in UL transmitting each other conflict in the situation that (, therein at same sonIn frame in the situation of emission control information) control information that is dropped.

In more detail, in the case of passing through the feedback of PUCCH, as RI transmitting and WBWhen CQI/PMI conflict (, when launch RI and WBCQI/PMI in same subframe time),Can abandon WBCQI/PMI. Alternatively, if situation about feeding back at such PUCCHLower RI transmitting conflicts with SBCQI, can abandon SBCQI. In addition, if positive SR andRI/PMI/CQI conflicts each other, can abandon RI/PMI/CQI. In addition, if subframe bindingThe uplink shared channel (UL-SCH) that operation is applied to and the RI/PMI/CQI in cycleReport conflict can abandon the RI/PMI/CQI report in cycle in corresponding subframe. CycleCQI/PMI and/or RI can be not multiplexing with the PUSCH transmitting of corresponding subframe. In addition,Suppose HARQ-ACK and RI/PMI/CQI and do not launch therein in the subframe of PUSCH thatThis conflict, if the predefined parameter providing from higher level (simultaneousAckNackAndCQI)Be set to 1, on PUCCH by multiplexing to CQI/PMI/RI and HARQ-ACK, otherwise,Can abandon CQI/PMI/RI.

As mentioned above, suppose and can in 3GPP version 8/9, launch a sub-image duration simultaneouslyMultiple control informations, must the limited control information of report. Can with SR, HARQ-ACK,UL-SCH(is the in the situation that of subframe bundling operation) > RI > WBCQI/PMI, WBCQI,The order of SBCQI is arranged the transmitting priority that is applied to control information conflict. Supporting expansionIn the system of exhibition antenna configuration, can feed back the different index (i1 and i2) for precoder.Therefore, need to determine the transmitting priority running in the conflict between RI, I1, I2 and CQI.Before determining the transmitting priority of such control information, must define to be used for defining controlling and believeThe Report mode of the report timing of breath.

Exemplary PUCCH Report mode

First, during the CQI/PMI/RI transmitting in cycle, cycle that can be based on final report (FR)RI calculate CQI, CQI/PMI, preferably subband is selected and CQI information, and can baseCalculating subband in the WBPMI in cycle of final report (FR) and RI selects and CQI value. In addition,Can be at different time points or same time point place two precoder indexes of report (I1 and I2).Consider above-mentioned situation, for example, can consider shown in table 38 for feedback information transmittingReport mode.

[table 38]

In table 38, I1 and I2 can indicate the rope of the code book being made up of precoder elementDraw, and PTI can indicate precoder type indication bit.

In the pattern 1-1-1 described in table 38, precoder index I1 can indicate based onThe precoder index that the RI launching in current subframe calculates/selects. Precoder index I2The precoder that can indicate the I1 of RI based on final report (FR) and final report (FR) and calculate/selectIndex. CQI can indicate the I1 of RI based on final report (FR), final report (FR) and current reportI2 and the value calculated.

In the pattern 1-1-2 shown in table 38, precoder index I1 and I2 can indicateRI based on final report (FR) and the precoder index that calculates/select. CQI can indicate based onThe value that the RI of rear report and the I1 of current report and I2 calculate.

At the pattern 2-1(1 shown in table 38) in, precoder index I1 can indicate baseThe precoder index that calculates/select in the RI of final report (FR). Precoder index I2 canThe I1 of the RI of instruction based on final report (FR) and final report (FR) and the precoder index that calculates/select.CQI can indicate RI, the I1 of final report (FR) based on final report (FR) and the I2 of current report and countThe value of calculating. When report (I1) between (RI+PTI) transmitting circulation and (I2+CQI) time,Can only report once (I1), and can report (I2+CQI) several times. Alternatively,When report (I1) between (RI+PTI) transmitting circulation and (I2+CQI) time, can only reportAccuse 2 times (I1), and can report (I2+CQI) several times. In another example, canWith report (I1) continuously where necessary, or, can alternately report (I1) and (I2+CQI).Otherwise, can be only report (I1) after (RI+PTI) report time, or can be only underReport (I1) before (RI+PTI) report time.

At the pattern 2-1(2 shown in table 38) in, precoder index I2 can indicate baseThe precoder index that calculates/select in the RI of final report (FR). Precoder index I2 can refer toThe precoder index that shows the I1 of RI based on final report (FR) and final report (FR) and calculate/select.SBCQI and SBI2 can indicate the I1 of RI based on final report (FR) and final report (FR) and calculate/Value and the index selected.

Pattern 2-1 shown in table 38 will be described in detail in below.

At the pattern 2-1[pattern 2-1(1 shown in table 38) and pattern 2-1(2)] can be rightYing Yu is with the report mould of the extend type configuration of the PUCCH Report mode 2-1 described in table 5Formula. Can be at 3GPPLTE version at the PUCCH Report mode 201 shown in table 5The PUCCH Report mode defining in 8/9 system, and be defined for report WBThe pattern of PMI/CQI and SBCQI. In this case, SBCQI selects among BPThe CQI of the SB selecting. Term " BP " can indication mechanism bandwidth subset. With the order of timeCyclically be chosen in the BP defining in system bandwidth, make to report the CQI of BP, andAnd also can report multiple SBCQI. In other words, can with identical time sequencing (RI) →(WBPMI/CQI) → (at the SBCQI of a BP) → (at the SB of the 2nd BPCQI) → ... → (at the SBCQI at nBP place) reports RI/PMI/CQI. At thisIn situation, if determine report circulation and the skew of PMI/CQI by RRC signaling, canTo circulate to report WBPMI/CQI and SBCQI in response to set report. Can be based onThe report of WBPMI/CQI circulates to set up RI to have the circulation corresponding with integral multiple. WithWBPMI/CQI compares launch time, can use offset indicator, with arrange skewBefore corresponding subframe, report RI.

For example, for the system (, 3GPPLTE version 9 systems) supporting the antenna structure of expandingThe PUCCH Report mode of middle use, can be defined in the PUCCH report mould shown in table 5The extended report pattern of formula 2-1.

As the PUCCH Report mode for using in 3GPPLTE version 8/9 systemCQI/PMI/RI feedback kind, can define four kinds of feedback kind (type-1, type-2, classesType-3, type-4). Type-1st, the CQI feedback of the subband of selecting for UE, type-2WBCQI feedback and WBPMI feedback, type-3rd, RI feedback, and type-4th,WBCQI feedback. Be similar to above-mentioned Four types, can be defined in 3GPPLTE versionFour kinds of CQI/PMI/RI feedback kind that use in the PUCCH Report mode of 10 systems. For example,Report Type 1 is RI/PTI feedback, and Report Type 2 is WBI1 feedbacks, and Report Type 3 isWBI1/CQI feedback, and Report Type 4 is SBI2/CQI feedbacks. According to type-1PTIArrange, can determine Report Type. For example, if type-1PTI is set to zero (PTI=0),Type-1, type-2 and type-3 can be for such reports. If type-1PTI is establishedBe set to 1(PTI=1), type-1, type-3 and type-4 can be for such reports.Therefore, can be defined in the pattern 2-1(1 shown in table 38) and pattern 2-1(2).

If with use one at 2Tx antenna transmission or the identical mode of 4Tx antenna transmissionPrecoder element indicated in precoder index, and PTI is always set to 1, makes type-1, type-3 and type-4 can be for reports. With in 3GPPLTE version 8/9 system, makeWith report scheme difference, can be at type-4 place transmitting SBPMI/CQI. For make forType-4 transmitting of 3GPPLTE version 10 systems operates similarly with 3GPPLTE version 8/9,Can cyclically be reported in the one or more BP in system bandwidth, and can report forThe PMI/CQI of preferred SB in (one or more) BP. In this case, can be withCome really with mode identical in the PMI/CQI of 3GPPLTE version 8/9 system circulation arrangesDetermine type-3 and type-4 report circulation. For example, can be according to following of arranging for PMI/CQIRing comes Report Type-3 and type-4. In addition, also can with for 3GPPLTE versionDuring the RI circulation of 8/9 system arranges, identical mode is identified for the circulation of type-1. For example,Can represent type-1 report circulation by the integral multiple of type-3 report circulation. In addition, canTo set up in the following manner deviant: can be before being positioned at type-3 reports subframe, withEmission type-1, subframe place of the corresponding preset distance of the subframe of predetermined quantity.

On the other hand, when coming with two precoder indexes as in 8Tx antenna transmissionWhen instruction precoder element, can report according to PTI value (Class1-type 2-type 3)Or (Class1-type 3-type 4). When select the set of two feedback kind according to PTI valueTime, must determine the report circulation for each feedback kind. Below detailed description is used in reference toShowing will be to the method detailed of the report period of each feedback kind application.

In first method, if independently set up Class1 (RI+PTI) with PTI instructionCycle (or circulation), can be the in the situation that of PTI=1 based on type 3(, in classThe type 3 using in type 1-type 3-type 4 Report modes) and set up Class1 (RI+PTI)Cycle.

In the second approach, if independently set up Class1 (RI+PTI) with PTI instructionCycle (or circulation), can be the in the situation that of PTI=0 based on type 3(, in classThe type 3 using in type 1-type 2-type 3 Report modes) and set up Class1 (RI+PTI)Cycle.

In the third method, if independently set up Class1 (RI+PTI) with PTI instructionCycle (or circulation), can be the in the situation that of PTI=0 based on type 2(, in classThe type 2 using in type 1-type 2-type 3 Report modes) and set up Class1 (RI+PTI)Cycle.

In the 4th kind of method, can differently set up Class1 (RI+PTI) according to PTI instructionCycle. For example,, the in the situation that of PTI=1, when foundation is used for launching a type 3(WBI2/CQI) or at least one type 4(SBI2/CQI) a circulation time, can be by Class1(RI+PTI(=1) cycle) is set to the integral multiple of an above-mentioned circulation. On the other hand,The in the situation that of PTI=0, when foundation is used for launching a type 2(WBI1) and a typeCirculation time 3(WBI2/CQI), can be by Class1 (RI+PTI(=0)) weekPhase is set to the integral multiple of an above-mentioned circulation. Can differently set up for PTI=0 and PTIThe minimal circulation of=1 request.

In Lung biopsy, if launch required one at PTI=1 place for CQI/PMIThe individual duration with at PTI=0 place be used for CQI/PMI launch another required duration notWith, can by two duration compared with long duration with for referencial use, andTransmitting feedback information repeatedly in the short duration. For example, needing one for PTI=0Type 2(WBI1) and a type 3(WBI2/CQI) transmitting, and for PTI=1 request type 4(SBI2/CQI) the situation of multiple transmittings under, the situation of PTI=0 canWith the duration corresponding to shorter, and the situation of PTI=1 can be corresponding to long continuingTime. In this case, the shorter duration can be repeated several times, make the knot of repetitionFruit can be corresponding to the longer duration. , can the in the situation that of PTI=0, repeatedly send outPenetrate type 2 and/or type 3. In the time that execution type 2 is reported, repeatedly Report Type 3.Alternatively, repeatedly Report Type 2 and type 3.

In the 6th kind of method, if for required one of the CQI/PMI at PTI=1 placeDuration with at PTI=0 place be used for CQI/PMI launch another required duration notWith, can be by the shorter duration in these two duration with for referencial use. LongerIn duration, can abandon for launching some required report contents or can be at nextIn individual Class1 emission duration, transmitting is for launching some required report contents. For example,Needing a type 2(WBI1 for PTI=0) and a type 3(WBI3/CQI)Transmitting, and for PTI=1 request type 4(SBIE/CQI) multiple transmittings and typeIn the situation of transmitting 3(WBI2/CQI), the situation of PTI=0 can continue corresponding to shorterTime, and the situation of PTI=1 can be corresponding to the longer duration. In this case,Have PTI=1 compared with long duration in, can abandon some information (for example, type 4),And can report a type 3 and a type 4. In addition, if type 4 is used band circulationReport CQI/PMI, also can launch another BP according to Class1 emission durationCQI/PMI.

On the other hand, below, can be applied to above-mentioned 3GPPLTE version by describing in detailThe example of the PUCCH Report mode of 10 systems.

Because defined multiple DL emission mode in 3GPPLTE version 10 systems, soCan define multiple PUCCH feedback report pattern to report for DL and to send out by PUCCHThe CSI penetrating. In this case, can use for use two precoder indexes (I1 andI2) (in the situation that of the present embodiment, I1 and I2 also can be called as PMI1 and PMI2 orW1 and W2) method and fixed for usually using at traditional 3GPPLTE version 8/9The method of the PUCCH Report mode of justice. Because limited PUCCH transmission resources, so needDesign PUCCH Report mode, wherein, the report bandwidth of consideration use code book sub sampling etc.Optimize.

Below, by detailed description according to an embodiment of the invention for being applicable to 3GPPLTEThe various examples of the PUCCH feedback report pattern of version 10 systems.

First, the size of PUCCH report bit can be no more than 11 bits (as at 3GPPLTEIn version 8). Consider this situation, must suitably set up each PUCCH reportThe bit size of pattern. In addition, be applied to the PUCCH of 3GPPLTE version 10 systemsReport mode can be defined in 3GPPLTE version 8 systems for PMI transmittingThe expansion (referring to PUCCH Report mode 1-1 and the 2-1 of table 5) of PUCCH Report mode.Therefore, can define three kinds of PUCCH Report modes.

PUCCH pattern-A is defined as the one expansion of the PUCCH Report mode 1-1 of table 5,PUCCH pattern-B is defined as the another kind expansion of the PUCCH Report mode 1-1 of table 5,And PUCCH pattern-C is defined as the expansion of PUCCH Report mode 2-1. Mode A,Mode B and pattern C can correspond respectively to pattern 1-1-1, pattern 1-1-2 and the pattern of table 382-1. In above-mentioned three kinds of PUCCH Report modes, can express one by Report TypeThe control information of individual time point place (, at a subframe place) transmitting. Below will describe in detailAt the Report Type of each PUCCH Report mode A, B and the transmitting of C place.

In PUCCH Report mode-A, can use two kinds of Report Types (type-5 and classesType-2a). Type-5 report is the feedback of RI and the W1 of associating compiling, and type-2a reportAnnouncement is the feedback of WBCQI and W2.

In PUCCH Report mode-B, can use two kinds of Report Types (type-3 and classesType-2b). Type-3rd, RI feedback, and type-2b is the anti-of WBCQI, W1 and W2Feedback.

In PUCCH Report mode-C, can use four kinds of Report Types (type-6, classesType-2a, type-7 and type-8). Type-6 report is the feedback of RI and the PTI of associating compiling,Type-2a is the feedback of WBCQI and W2. Type-7th, WBW1 feedback, and typeThe-8th, there is the SBCQI of designator and the feedback of W2 of selected band.

In different subframes, report above-mentioned Report Type, therefore need multiple subframes (TTI)Determine whole pre-coding matrix W in the situation that of PUCCH pattern-A and pattern-C andThe CQI being associated.

The sub sampling of PUCCH Report mode will be described in detail below. Below will describe withPUCCH Report mode-A that the extended version of PUCCH Report mode 1-1 is corresponding andPUCCH Report mode-B.

Therein not to PUCCH Report mode-A and PUCCH Report mode-B application codeIn the situation of this sampling, can be according to summing up for report type as the order value as shown at table 39The feedback overhead (quantity of the bit of, asking) of type.

[table 39]

In table 39, exceed 11 ratios for some type-2 reports of PUCCH pattern-BSpy, makes them also exceed the restriction of PUCCH transmitting bit. Therefore, can be at PUCCHThis sub sampling of type-2 report application code at pattern-B place, as shown at table 40.

[table 40]

Can find out from table 39, type-2a report is no more than 11 bits, makes to use sonSampling, and type-5 report can need the twice of the bit of type-3 report. Because type-5 and type-3 reports carry order information, so type-5 and type-3 type should have robustReliability. Therein order information have for the high priority of PUCCH report and need toIn one subframe, report in the situation of several types, CQI and PMI can launch subframe from RI and decline.Consider the problems referred to above, also can be to this sub sampling of type-3 report application code, to increaseThe reliability of order feedback.

Can for example represent to apply sub sampling to type-5 report to 44 by table 41. Table 41With 42 exemplary cases that maximum order 2 is shown. Table 43 illustrates the exemplary cases of maximum order 4.Table 44 illustrates the exemplary cases of maximum order 8.

[table 41]

[table 42]

[table 43]

[table 44]

In the example of table 41, can be fixed to 5 bits for type 5 bits of RI,And W1 can be used as complete or collected works, cause the systematic function or the handling capacity that increase.

In the example of table 42, can be used as 4 bits for type-5 bit of RI,Make can than the example of table 40 more robust many RI that launch. On the other hand, because use sonThe W1 of sampling instead of the complete or collected works of W1, so the systematic function of table 42 or handling capacity are lower than table40 systematic function or handling capacity. Therebetween, can find out from table 42,43 and 44, not examineConsider in the situation of maximum order, those of the W1 of order 1 and W2 and order 2 are identical, cause nested spyThe realization of property.

Make comparisons with above-mentioned PUCCH pattern-A and PUCCH pattern-B, can be by usingCode book sub sampling in PUCCH pattern-A keeps homophase attribute, and simultaneously, canReduce wave beam granularity. On the other hand, although by the code book for PUCCH pattern-BSampling provides the more accurate wave beam granularity than PUCCH pattern-A, but homophase attribute can notAvoid deteriorated.

Corresponding with the extended version of conventional P UCCH Report mode 2-1 by describing in detail belowPUCCH Report mode-C.

Can represent the feedback overhead for PUCCH pattern-C request by table 45 below(quantity of feedback bits).

[table 45]

Can find out from table 45, if be set to 1(, PTI for type-6 report PTI=1), exceed 11 bits for the type-8 required bit of report at order 2 to 4 places,Making can be to too much this sub sampling of bit application code. With for above-mentioned PUCCH pattern-BThe similar principle of principle of code book sub sampling can be applied to the W2 of type-8. In addition,As shown at table 45, because the PTI of bit instruction, so PUCCH pattern-CRI feedback reliability can be lower than the RI feedback reliability of above-mentioned PUCCH pattern-B. In addition,The dutycycle that the dutycycle of W1 report is longer than RI. Consider this attribute, can determine reportReport time point and the priority of type.

The priority of feedback information

If will describe the report mould that has defined as mentioned above feedback information transmitting timing in detail belowThe control information that formula will abandon when the conflict between the control information in every kind of pattern.

Can report by UL channel the CQI/PMI/RI information of DL channel. Can basisAttribute (, report period, the bandwidth that apply and other control letter of single control informationSelection/calculating basis of breath) the next transmitting priority of determining for each control information, andLike this, below in detail, the attribute of single control information will be described. Can be according to being reportedLayer maximum quantity determine RI bit. RI compares generally when longer with CQI/PMIBetween locate to be reported, and see from the viewpoint of a carrier wave can be taking system bandwidth (WB) as unitBe employed.

Can be used as the designator transmitting PMI of code book, code book is as answering to DL transmittingWith the set of pre-coding matrix. Can represent by single index maybe can be by two notSame index (, i1 and i2) represents this code book. For example,, at 3GPPLTEIn the situation of the code book of the 2Tx in version 8/9 or the definition of 4Tx antenna transmission, can usePrecoder element determined in single index. At the 3GPP for supporting the antenna configuration of expandingIn the situation of the 8Tx antenna transmission of new definition in LTE version 10 and the code book that defines, canUse two different designators (I1 and I2) to determine precoder element. Using instructionIn the situation of symbol (I1 and I2), can differently define report period and the institute of each indexThe frequency bandwidth of application. For example, I1 can indicate the line index of code book. Can be relatively longOr short time report I1, and I1 can be applied to and from the viewpoint definition of a carrier wave beCommand wide (WB). For example, I2 also can indicate the column index of code book. Can be shorterTime report I2, can apply I2 to the system bandwidth (WB) of the viewpoint definition from a carrier wave,And can on subband (SB) basis, apply I2.

If see the time report I1 comparing with I2 designator longer from the viewpoint of transmitting circulationDesignator, can report I1 designator with the priority higher than I2 designator. In other wordsSay, in same subframe, set up under the condition of I1 and I2 report, can launch I1, and canAbandon I2.

Can calculate CQI based on determined precoder, and can with I2 designator onePlay report CQI.

The transmitting of describing feedback information below with reference to the PUCCH Report mode of table 38 is preferentialLevel.

In the pattern 1-1-1 of table 38, can be in long-time report to the RI of WB application andI1, and I2 and the CQI that can apply to WB in short time report. Therefore, can be from table38 pattern 1-1-1 finds out, if (R1+I1) launch time point with (I2+CQI) launch timePoint conflict, can abandon (I2+CQI). , can be at the I2 and the CQI that report than the short timeRI and the I1 of the higher long-time report of priority report.

In the description 1-1-2 of table 38, can report for a long time to the RI of WB application, andAnd, can report in short time to I1, I2 and the CQI of WB application. In the pattern of table 38In 1-1-2, if the RI report period conflicts with report period (I1+I2+CQI), can abandon(I1+I2+CQI). , can provide than I1, the I2 of short time report to the RI of long-time reportThe priority high with CQI.

In the pattern 2-1 of table 38, RI can have the priority higher than PMI/CQI. ,At the pattern 2-1(1 of table 38) in, if (RI+PTI) the report period with (I1) or (I2+CQI)Report period conflict, can abandon (I1) or (I2+CQI). In addition, at the pattern 2-1 of table 38(2), in, if (RI+PTI) conflicted with (I2+CQI) _ WB or (I2+CQI) _ SB, canAbandon (I2+CQI) _ WB or (I2+CQI) _ SB.

In addition, in the pattern 2-1 of table 38, can determine report subsequently according to PTI instructionThe attribute of information. If instruction PTI=0(is, pattern 2-1(1)), can reportTo the I1 of WB application and the I2 and the CQI that apply to WB. In this case, can be than I2The time report I1 long with CQI, or can be at the time report I1 identical with I2 and CQI.If PTI indicated value 1(is, pattern 2-1(2)), report to the I2 of WB application andCQI, and report is to I2 and the CQI of subband (SB) application. In this case, than toI2 and CQI that the long time report of the I2 of SB application and CQI is applied to WB. At pattern 2-1In, report PTI together with RI, and at long-time report PTI.

In pattern 2-1, about (RI, PTI), (I1) _ WB, (I2, CQI) _ WB and (I2,CQI) _ SB launches circulation, can be at time report (I1) _ WB longer than (RI, PTI). Therefore,In pattern 2-1, can be at time report (the I1) _ WB longer than (RI, PTI) _ WB. , asReally (I1) _ WB and (RI, PTI) _ WB conflict, can abandon (RI, PTI) _ WB.

Embodiment 7

Embodiment 7 relates to a kind of for determining energy under the condition in application multicarrier or carrier aggregationEnough be applied to the method for the transmitting priority of multiple control information reports. In the following description,Multicarrier or carrier aggregation represent to configure one or more carrier waves, and (or one or more service is littleDistrict). , embodiment 7 can be applied to that wherein in UE, to configure multiple carrier waves (or multipleCommunity) situation.

In the situation that multicarrier is launched, when reporting to eNB by uplink carrier from UEWhen the control information of the multicarrier configuring in downlink, can be specific by being arranged toA carrier wave (for example, ULP-community) of object is reported control information. In this case,Can for each carrier wave be configured for independently each DL carrier wave control information send outPenetrate circulation. , positive SR, HARQ-ACK and CQI/PMI/RI etc. can have for singleThe independent transmission circulation of carrier wave, and can be reported by uplink carrier. If logicalCross a UL carrier wave and carry out emission control information, dissimilar control information may be rushed each otherProminent, make to determine to which control information and assign transmitting priority. Below will describe in detailFor effectively supporting the various control information transmitting scheme of DL multicarrier transmitting.

In first method, if report is for the HARQ-ACK of positive SR or DL multicarrierA time point of information is identical with another time point of report CQI/PMI/RI, can loseAbandon CQI/PMI/RI.

In the second approach, can report for each DL independently launching circulation placeThe CQI/PMI/RI information of carrier wave, and, can determine according to DL carrier wave priorityCQI/PMI/RI reports priority. For example,, if carrier wave-A has higher preferential than carrier wave-BLevel, if the CQI/PMI/RI of carrier wave A conflicts with the CQI/PMI/RI of carrier wave B, canAbandon the CQI/PMI/RI for carrier wave B.

In the third method, in multicarrier transmitting, can determine about working as CQI, PMITo abandon in the time that CQI/PMI/RI report circulation place for multiple DL carrier waves conflicts each other with RIThe information of which information. With DL carrier type independently, can refer to according to feedback information attributeSend priority. Can calculate and select CQI/PMI by the RI based on final report (FR). If forPrecoder is reported multiple indexes (for example, I1 and I2), RI that can be based on final report (FR)Calculate and select each precoder, and RI that can be based on final report (FR), last reportThe I1 accusing and the I2 of current transmitting calculate the CQI launching together with I2. Alternatively, canCalculate and report together with I1/I2 with the I1/I2 of the RI based on final report (FR) and current reportCQI. Consider above-mentioned situation, can assign to the control information in long-time report higher excellentFirst level. For example, I1 has limit priority, and RI has the priority lower than I1, and I2Can there is the priority lower than RI with CQI. If identical with high priority control informationThe control information of time point place transmitting low priority, can abandon low priority control information, andAnd can abandon high priority control information.

About priority upper of CSI report in cycle that uses PUCCH on multiple carrier wavesThe method of stating can be expressed as follows.

First,, if configure one or more Serving cells in UE, UE can be anyIn given subframe, transmitting is used for the only channel condition information of a Serving cell (CSI).

If the feedback information of first service community is according to the feedback information attribute in any subframeAnd there is the priority higher than second service community, the feedback information of this Serving cell can toolThere is lower priority, and can be dropped. About feedback information priority, for example, bagDraw together RI or PIM(or WBPMI(W1 or the I1 with long report circulation)) CSI canTo there is the priority higher than other CSI. From other CSI, long report circulation (or WBAttribute) PMI and/or CQI can have higher than short time report cycle P MI and/or CQIPriority.

Embodiment 8

Embodiment 8 relates to and a kind ofly losing for reporting wherein under the condition of the multiple control informations of reportAbandon the method for the situation of specific control information, and relate to abandoning RI or I1(PMI or W1)Situation under the detailed report method that uses.

Although embodiment 8 illustrates therein from the viewpoint of a carrier wave and sees and abandon RI or I1The method for reporting using in exemplary cases, but it should be noted that scope or the essence of embodiment 8God is not limited to this, and also can be applied to other example. For example, it should be noted that enforcementExample 8 also can be applied to following example: in this example, and when occur feedback information in UEFor example, when (, CSI) conflict, abandon feedback on reservation information based on priority, in this UE,Configure disclosed multiple carrier wave (or one or more Serving cell) in the present embodiment. ExampleAs, as for wherein in response to the priority of CSI information attribute or pre-for Serving cellDefinition priority and the information that abandons be RI or I1(, PMI or the W1 of long-term WB attribute)The detailed CSI method for reporting of situation, can use example below.

According to pattern 2-1(, pattern 2-1(1) and pattern 201(2)) PUCCH passed throughReport periodically under the hypothesis of CQI/PMI/RI, below detailed description is abandoned to control thereinThe method for reporting using in the situation of information.

In Figure 27, be described in transmitting control in the situation of pattern 2-1 below with reference to table 46The method of information processed. When Figure 27 illustrates the RI/PMI/CQI report in the situation that of pattern 2-1

Between point example. Table 46 illustrates the RI/PMI/CQI report time in the situation that of pattern 2-1

Point and attribute.

[table 46]

Can determine I1, I2 and CQI according to the instruction of the RI of report. The feelings of reference table 46Condition 1, if report order-N information is selected and then report from the code book for order-NI1. , select I2 based on selected I1 thereafter, and calculate based on selected I1 andReport CQI. Thereafter, if change make RI value as order-M of order value report, based on order-M selects I1 and I2, and then calculates CQI.

On the other hand, illustrate and abandoning RI at the situation 2-1 shown in table 46 and situation 2-2Condition under control feedback information attribute.

The situation 2-1 of table 46 and situation 202 illustrate in the time abandoning RI by I1, I2 and CQIThe RI information of quoting. If select and calculate I1, I2 and CQI based on the most newly reported RI,Although it is still no problem in select/calculating I1, I2 and CQI to have abandoned RI. In other wordsSay, in situation 2-1, if abandoned the RI that is used to indicate order-M, UE can be based onI1, I2 and CQI are selected/calculated to the most newly reported RI order value (, N). In addition, althoughPTI is set to 0 or 1 as in situation 2-2, can be according to the most newly reported order valueSelect and calculate I1, I2 and CQI. In this case, preferably, in the feelings of PTI=1RI under condition can report the same with the order information of the IR report the PTI=0 in the situation thatOrder information.

On the other hand, it should be noted that and may unexpectedly lose I1. Can be by effect for I1 informationIn the information that I1 selects and CQI calculates. If order information abandons I2 once changing into another,May in I2 selection and CQI calculating, there are some difficulties. For example,, as at table 46The condition shown in situation 3-1 and situation 3-2, order information being changed from N order to M order,In the I2 that will select subsequently/calculate and CQI, do not comprise the I1 based on order-M, cause select/The appearance of unexpected problem in calculating. Therefore, in the situation that abandoning I1, need specially treated to holdRow 11 is selected and CQI calculates.

By describing in detail, for selecting in the time abandoning I2/calculating, I2 and CQI's is of the present invention belowExample.

Embodiment 8-A

Calculate if must carry out based on order M I2/CQI, can be based in previously reportThe most newly reported I1(in the I1 value of order-M is for order-M) calculate I2 and CQI. Can replaceSelection of land, in the situation that must carrying out I2/CQI calculating based on order M, can predefine and makeUse the I1 based on order-M. In other words, therein the most newly reported I1(, a PMI)Have in the situation of the RI different from the most newly reported RI, or there is no therein (abandoning)In the situation of the most newly reported I1, can be based on predefined I1(, a PMI) selectSelect and calculate I2(, the 2nd PMI) or CQI. For example, can be by predefined I1(One PMI) be defined as I1(the one PMI), this I1 have based on the most newly reported RIThe minimum allowing in code book subset restriction (codebookSubsetRestriction) bitmap parameterIndex. Therefore,, although symbol is for the I1 of the order-M of draft report, can select and countCalculate I2 and CQI for order-M, as shown in table 47 below.

[table 47]

Embodiment 8-B

If order is changed into order M from order N, if abandon the I2 for order-M, can weighWrite the order information of the most newly reported I1.

For example, transmitting is therein used to indicate the RI of order-M, abandons the I1 report for order-M,And must select and calculate in the situation of the I2/CQI based on order-M, the most newly reported I1 canTo be the designator of selecting based on order-N. In this case, ignore the most newly reported RI and phaseAssociated order information (, order-M), and can be based on the most newly reported I1 and order value (order thereof-N) calculate I2 and CQI. In addition, even when necessary basis is at next RI(instruction order-M)When in transmitting circulation, the PTI of report indicates to report WBI2, CQI and SBI2/CQI, abandonBased on the selected I1 of order-M, make the order based on the most newly reported I1 and I1 to calculate I2And CQI, as shown in table 48 below.

[table 48]

Embodiment 8-C

If abandoned I1,, at next RI report circulation place instruction PTI=0, making canWith report I1, and the explanation that shown in table 49 below, it is associated.

[table 49]

Embodiment 8-D

If abandon I1, postpone I1 report, and, can report the I1 drawing. For example,Can report I1 in the N subframe place after I1 report time.

For example, can set up in the following manner the value of N: N subframe is set in original I 1Any one of CQI report time point after report time. Following for the promise of CQI reportRandom time point place in ring, can replace control information that must original transmitted and report and abandonI1. For example, as shown in Figure 28 (a), if carrying out I1 when report planning report I2/CQI,Can replace report I2/CQI and report I1. Alternatively, carrying out initial after abandoning of I1CQI report time place, can report the I1 abandoning. As shown at Figure 28 (b), can be withFollowing manner is set up N value: also can report at the initial subframe place after original I 1 report timeThe I1 abandoning, as shown in table 50 below.

[table 50]

Embodiment 9

Embodiment 9 illustrates preferential when the control information transmitting of report when multiple control informationLevel, and the control information also illustrating for being based upon multicarrier transmitting use is launched preferentialThe method detailed of level. In the following description, multicarrier or carrier aggregation application represent configuration oneIndividual or multiple carrier waves (or one or more Serving cell). , embodiment 9 can be employedTo the situation that wherein configures multiple carrier waves (or multiple community) in UE.

When 3GPPLTE systematic survey DL channel and by UL channel reporting it time, canAs DL channel information reporting RI, PMI, CQI etc. In this case, when passing through PUCCHWhile reporting DL channel information, passable for carry out the method for reporting channel information by PUCCHSubstantially be divided into two kinds of patterns according to the frequency granularity based on CQI/PMI. For reporting to WBThe pattern of the CQI/PMI of application can be called as PUCCH Report mode 1-1, and for reportThe pattern of accusing WBCQI/PMI and SBCQI can be called as PUCCH Report mode 2-1.PUCCH has the limited channel capacity that can once be launched, and making can be when differentBetween some report order, WBCQI/PMI and SBCQI. Figure 29 illustrates for reporting independently channelThe exemplary time point of information number. Ratio between the report circulation of single channel information number, at longer time report RI, and can be at shorter time report SBCQI/PMIAnd SBCQI.

Consider multicarrier (carrier aggregation) transmitting, must measure and report that each DL carriesRipple information. Can for example, report DL channel by a UL carrier wave (, ULP-community)Information, and, the time point of each DL carrier information of report can be set up to have for oftenThe independent transmission circulation of individual DL carrier wave. In this case, may produce a kind of situation, wherein,Must report that the DL carrier information that will report by a DL carrier wave (, can be simultaneously simultaneouslyReport the information number of different DL carrier waves). In order to solve the above problems, be identified for everyA CSI(RI, PMI, CQI) priority make to launch high priority message, andAnd can abandon low priority information. As shown in Figure 29, can report order letter in the long periodBreath, can report CQI/PMI information in the short period, makes to refer to long period report informationDistribute the information of penetrating, and therefore, can report up-to-date channel information.

In order to indicate the precoding information for the 8Tx antenna transmission in 3GPPLTE-system,Definition is used for using two indexes (I1 and I2(or PMI1 (W1) and PMI2 (W2))) generationCode book. Must report two indexes, make precoder component information become clear and definite. Can beLong period is as WB information reporting I1, and can be in the short period as SB information reportingI2. Compare with the CSI report using in traditional 3GPPLTE version 8/9, need in additionDefinition is about the information which scheme to report two code book designators by. For report RI,I1, I2 and CQI, can apply the pattern 2-1(1 such as table 38) and pattern 2-1(2)PUCCH Report mode below.

Can find out from the pattern of table 38 201, according to precoder type indicator (PTI)Determine the attribute of the information of Next Report. , if the PTI launching together with RI is establishedBe set to 0, launch W1, and then launch WBW2 and CQI. In this case, baseSelect and calculate W2 and CQI in the W1 of previous report. If PTI is set to 1,Transmitting WBW2/CQI, and then launch SBW2/CQI. Figure 30 is illustrated in pattern 2-1In at the CSI report time point at PTI=0 and PTI=1 place.

Consider CSI report circulation, slow (not continually) reports W1 as shown in Figure 30,And, the report (RI+PTI) comparatively continually of comparing with W1. In addition, report continually WBW2/CQI and SBW2/CQI. Therefore, as mentioned above, when being chosen in multicarrier transmitting spyWhile fixing time the CSI that will launch, can be W1 by the transmitting priority definition of each CSI >RI+PTI>W2=CQI。

On the other hand, also can use such as the pattern 1-1-1 of table 38 and pattern 1-1-2PUCCH Report mode. Can come really according to the report circulation of such PUCCH Report modeDetermine the transmitting priority of CSI information. ,, in the pattern 1-1-1 of table 38, can define(RI+I1) _ WB > priority of (I2+CQI) _ WB. In the pattern 1-1-2 of table 38, canDefinition (RI) _ WB > priority of (I1+I2+CQI) _ WB.

In this case, (the RI+I1) _ WB of DL carrier wave transmitting and the second carrier wave(RI) _ WB transmitting can conflict each other in the time that multicarrier is launched.

Because reporting I1 than the relative longer time of RI, so the impact that I1 abandons can be largeThe impact abandoning in RI, makes I1 can have the priority higher than R1. , Ke YishiExisting (RI+I1) > priority (RI).

Consider three feedback models (pattern 1-1-1, pattern 1-1-2 and pattern 2-1) of table 38,(I1) _ WB can have limit priority.

Can be by the CSI report priority for using PUCCH when multiple carrier wave above-mentionedProject expressing is as follows.

First,, when configure one or more Serving cell in UE time, UE can give anyThe only CSI of a Serving cell of transmitting in fixed subframe.

The feedback information of supposing first service community is according to the feedback information attribute of subframe arbitrarily and toolHave the priority higher than second service community, the feedback information of second service community can haveLower priority, and be dropped. For example, about feedback information priority, RI,(RI+I1) _ WB, (RI+PTI) or I1_WB can have the priority higher than other CSI.

Embodiment 10

Embodiment 10 illustrates preferential when the control information transmitting of report when multiple control informationLevel, and embodiment 10-A and 10-B illustrate the feedback that will use in the time abandoning RI and PTIMethod.

Embodiment 10-A

In the case of the PUCCH Report mode of the pattern 2-1 such as table 38, may becauseA variety of causes and abandon (RI+PTI). In this case, can be according to the most newly reported (RI+PTI)Instruction is determined will be in the upper once information of report.

For example, if report RI+PTI (=0), report (W1) _ WB, and then report(W2+CQI) _ WB. In this case, if abandon RI+PTI (=0), can be according toThe PTI value of rear report is determined the information that will report subsequently. Can be as can be seen from Figure 31, if lostAbandon RI+PTI (=0), the PTI of final report (FR) is set to 1, makes report (W2+CQI) _ WB, and then report (W2+CQI) _ SB.

Embodiment 10-B

In the case of the PUCCH Report mode of the pattern 2-1 such as table 38, if abandoned(RI+PTI), can will be with according to being calculated by the order value of the most newly reported RI instruction and selectingThe information of rear report.

For example, if report RI (=M)+PTI, must select based on order-M/calculate andThen be reported in W1, the W2 and the CQI that after RI (=M)+PTI, launch. In this case,If abandon RI (=M)+PTI, can the RI order value based on final report (FR) select and calculate and wantThe information of report subsequently. In Figure 32, if abandon RI (=M)+PTI, last based on basisReport RI(=N) order-N instead of order-M select and report W1_WB. In these feelingsUnder condition, can select and calculate W1/CQI subsequently based on order-N and the W1 based on order-N.If determine PTI instruction time, can report PTI instruction according to the determined time.

Embodiment 11

Embodiment 11 illustrates and can be applied to PUCCH Report mode and MU-MIMO situationCode book sub-sampling methods and the definition of PUSCH Report mode.

Embodiment 11-A

For example, as the system (, 3GPPLTE version 10 systems) of supporting the antenna structure of expandingThe extended version of conventional P UCCH Report mode, can be applied in three kinds shown in table 39PUCCH Report mode [(pattern 1-1-1, pattern 1-1-2, pattern 2-1) or (pattern-A,Pattern-B, pattern-C)].

RI and the I1 of pattern 1-1-1 report associating compiling, and report broadband CQI and broadband I2.Pattern 1-1-2 is the pattern for transmitting (RI) _ WB and (I1+I2+CQI) _ WB. MouldFormula 2-1 can launch different feedback informations. If PTI is set to zero (PTI=0),Can launch (RI+PTI(0)), (I1) _ WB and (I2+CQI) _ WB. IfPTI is set to 1(PTI=1), can launch (RI+PTI(1)), (I2+CQI)_ WB and (I2+CQI) _ SB. On the other hand, in the present embodiment, also can pass through respectivelyW1 and W2 represent two precoder index I1 and I2.

The method that realizes report bandwidth optimization by following manner will be described in detail below: to oftenIndividual this sub sampling of PUCCH Report mode application code, and resemble at traditional 3GPPLTE simultaneouslyIn version 8/9, keep like that PUCCH feedback to cover.

Shown in table 39, opening for the signaling of PUCCH Report mode 1-1-1 and 1-1-2 requestPin. In table 39, pattern-A is corresponding to PUCCH Report mode 1-1-1, and pattern-BCorresponding to PUCCH Report mode 1-1-2.

Can find out from table 39, for the type at PUCCH Report mode 1-1-1 place-5(connectionCompile in collaboration with the RI and the WI that translate) need to 6 bits. Because owing to combining the RI of compiling and WI and toRI and WI distribute 6 bits, be less than widely traditional 3GPP for the covering of RI transmittingLTE version 8 systems. As a result, RI be can run into and failure or performance degradation detected. Therefore, canIncreasing RI with WI sub sampling covers. In pattern 1-1-1, can report than type-5Updating type-2a(W2 and CQI more continually) report, make to recognize and needn't always protectProtect type-2a. Therefore, the bandwidth of just reporting is no more than the limit of a bit, needn't useW2 sampling.

In PUCCH Report mode 1-1-2, do not combine compiling together with other CSI informationRI, makes to keep RI with mode identical in traditional 3GPPLTE version 8 systemsCover. But, as shown at table 39, the in the situation that of order-1, order-2, order-3 and order-4,For type-2b(W1+W2+CQI) report need to exceed the signaling consumption of 11 bits. Therefore,In order to reuse the PUCCH form 2 of 3GPPLTE version 8 systems, need code book to adoptSample.

First, in detail, the son that can be applied to PUCCH Report mode 1-1-1 will be describedThe method of sampling.

W1 candidate can be quantitatively different according to launching order. , as at table 11 to 18Shown in, can be respectively for the quantity of order 1 to 8 W1 candidate be set to 16,16,4,4,4,4,4 and 1. If combine compiling and report RI and W1, by 6 bits (=Ceiling (log2 (53))) represent asked signaling consumption. Cover in order to expand RI, canBy W1 sub sampling, signaling consumption is reduced to 4 or 5 bits. Shown in table 51 belowThe example of W1 sub sampling.

[table 51]

In twin-stage code book structure, between wave beam group, there is overlapping wave beam. Can be from table51 Alt-1 scheme is found out, although come to answer to W1 by only get rid of odd number W1 value from code bookWith sub sampling, still can keep all wave beams of code book. But, from other subframe transmittingFor constructing W1 and the W2 of whole code book, make and the whole code that is not employed sub samplingThis use is compared, and there will be performance degradation. Meanwhile, can be from the Alt-2 scheme of table 51Find out, if application can be got rid of from code book the sub sampling of more wave beam, can not be withWherein can keep the Alt-1 scheme of all wave beams of code book differently to use some of code bookWave beam, causes the appearance of performance degradation.

Table 52 be illustrated in 8 × 2SU-MIMO transmitting based on the application of code book sub samplingThe system level performance of PUCCH Report mode 1-1-1. Table 52 is illustrated in (4+4) and is used asFor the W1 of order-1 and order-2 and W2 bit and to its application Alt-1 and Alt-2 schemeThe average frequency spectrum effect of the antenna structure for cross-polarized antenna structure and co-polarization under conditionRate (SE) and cell edge SE. The Alt-1 scheme of table 52 is on limit, all average SEHe communitiesIn edge SE, produce performance bounds deteriorated. And Alt-2 scheme produces relatively in cell edge SEHigh performance degradation.

[table 52]

Can find out from table 52, the code book keeping system performance of the sub sampling of 5 bits, and anotherThe code book of the sub sampling of 4 bits reduces systematic function and maximum 7% corresponding being scheduled toQuantity. Therefore, although covering the RI lower than Alt-2 scheme relatively, the RI of Alt-1 scheme covers,But from the viewpoint of systematic function, Alt-1 scheme than Alt-2 scheme more preferably.

Below, the sub sampling that can be applied to PUCCH Report mode 1-1-2 will be described in detailMethod.

In PUCCH Report mode 1-1-2 (W1+W2+CQI) report, at same sonIn frame, report W1 and W2. Therefore, can keep 11 bits or less with sub samplingReport bandwidth. As mentioned above, (example in the case of the sub sampling for W1 value being reduced to 1 bitAs, among 16 indexes, select the situation of 8 subset of indices therein), can keepAll wave beams of code book, making can minimization system performance degradation. But, if passed throughThe bit that exceedes 1 bit carrys out sub sampling W1 value, gets rid of the wave beam group of specific direction from code book,Make the systematic function can be by greatly deteriorated. Therefore, may be preferably, with order-2 to order-4 phaseAssociated ground, carries out 1-bit sub sampling at W1 place, and gets rid of more bit at W2 place.

Table 53 below illustrates and can be applied to the exemplary of PUCCH Report mode 1-1-2Sub-sampling methods.

[table 53]

Referring to table 53, according to Alt-1 scheme and Alt-2 scheme, only for order-1 to order-4W1 place reduce 1 bit so that the wave beam group that prevents loss all. Therefore, according to askBandwidth carry out sub sampling W2.

Table 54 be illustrated in 8 × 2SU-MIMO transmitting based on the application of code book sub samplingThe level of the systematic function of PUCCH Report mode 1-1-1. Table 54 is illustrated in (4+4) and is usedAct on the W1 of order-1 and order-2 and W2 bit and to its application Alt-1 and Alt-2 schemeCondition under the average frequency spectrum of the antenna structure for cross-polarized antenna structure and co-polarizationEfficiency (SE) and cell edge SE.

[table 54]

Can find out from table 54, from W2 sub sampling get rid of 8 Tx antennas some guiding toAmount (steeringvector), makes the performance degradation of the antenna structure of co-polarization relatively be greater than friendshipThe performance degradation of the antenna structure of fork polarization. On the other hand, in cross-polarized antenna structureThe performance bounds producing is deteriorated.

Therefore, can recognize, can be adapted to by the W1 using by 3 bit sub samplingsCondition under use the code book of sub sampling and the performance degradation that causes. Therefore, preferably,Alt-1 scheme is applied to PUCCH Report mode 1-1-2.

Below, the sub sampling side that can be applied to PUCCH Report mode 2-1 will be described in detailCase.

In PUCCH Report mode 2-1, can feed back four kinds of Report Types [(RI+PTI),(W1) _ WB, (W2+CQI) _ WB, (W2+CQI) _ SB]. Can be according to PTISelect to change each Report Type. Table 45 is illustrated in PUCCH pattern 2-1(by showingPattern-C in 45 represents) situation under the required signaling consumption of each Report Type. SupposeIn the case of (W2+CQI) _ SB report at PTI=1 place, in table 45, comprise forThe L-bit indicator of the subband that UE selects.

In table 45, the situation of order-2, order-3 and order-4 under the condition of instruction PTI=1Under, for reporting the L-bit indicator for each of (W2+CQI) _ SB and SBRequired expense exceedes 11 bits. The signaling consumption that can reduce to be associated makes again to makeWith the PUCCH form 2 of 3GPPLTE version 8. In order to reduce signaling consumption, can useTwo kinds of methods (option one and option 2) below. Option one can newly define and not use L bitThe selected predetermined SB circulation with designator. Option 2 is carried out W2 sub sampling, makes to weighThe band designator that the new L-of use bit is selected.

The in the situation that of option one, can by PUCCH form 2 report SBCQI andSBW2. But, according to option one, increase the CQI report circulation for each subband, makeCan use the predefined SB period, to produce more delicately performance at selection of time channel place badChange. In addition, should be in BP(portions of bandwidth) report WBCQI between period of report durationAnd WBW2, the CQI report that can increase widely at each subband place is circulated, leadCause the performance degradation of increase.

The in the situation that of option 2, report SBCQI together with the bandwidth indicator of selecting with L-bitAnd SBW2, make for carrying out in order-2, that order-3 and order-4 place carry out such report is requiredThe quantity of bit exceed 11 particular value. Therefore, can apply W2 sub sampling, and table55 illustrate the example of W2 sub sampling.

[table 55]

Alternative	W2
		Order-1	2 bits: (0,1,2,3)
Order-2	2 bits: (0,1,8,9)
		Order-3	2 bits: (0,2,8,10)
Order-4	2 bits: (0, Isosorbide-5-Nitrae, 5)
		Order-5～8	0 bit

Table 56 is illustrated in using in option 2 and option 2 in 8 × 2SU-MIMO transmittingThe level of the systematic function of PUCCH Report mode 2-1. Table 56 is illustrated in two kinds of method (options1 and option 2) situation under flat for the antenna structure of cross polarised antenna structure and co-polarizationAll spectrum efficiency (SE) and cell edge SE. Suppose for measure of system performance, 5ms'sEach report circulation place report SBCQI and SBW2, and upgrade at the interval of 45msWBW1. In addition, suppose the W2 that applies 2-bit sub sampling to option 2.

[table 56]

Can find out from table 56, the average SE of option one than the average SE of option 2 low 3% to4% system performance degradation, because during for the report operation of the WBCQI/WBW2 of option oneSection is greater than the report operation time period of the WBCQI/WBW2 of option 2. For example, with diagramThe Figure 33 of report period in the situation of the predefined SB circulation at the system bandwidth place of 5MHzIn identical mode, option one is reported the CSI of all subbands, makes WBCQI/WBW2'sReport circulation is greater than option 2.

As mentioned above, option 2 has the performance higher than option one, makes in systematic function excellentChoosing, comprises the L-bit indicator of the band of selecting for UE, and applies to option 2W2 sub sampling. In addition, in legacy system (3GPPLTE version 8 systems), useUE is with selection function, makes also to reduce the complexity for option 2 implementations.

Therefore, according to the code book sub sampling of innovation that is applied to each PUCCH patternScheme, reuses conventional P UCCH form 2, and can minimization system performance degradation.

On the other hand, table 57 illustrates the systematicness being applied to shown in table 52,54 and 56The parameter of the emulation of energy. In addition, table 58,59 and 60 illustrates and is applied to PUCCH formThe ginseng of the emulation of the systematic function of 1-1-1, PUCCH form 1-1-2 and PUCCH form 2-1Number.

In MU-MIMO transmitting, the quantity of transmitting (Tx) layer of transmitter and receiverReceive the quantity difference of (Rx) layer. In addition, receiver is reported under the hypothesis of SU-MIMOCSI, make the channel information reported by receiver can be different from actual channel information (, byThe channel information of receiver report may not mate with actual channel information). For example, usingIn the situation of conventional P USCH Report mode 3-1, feed back mistakenly the CSI of MU-MIMO,Make to need a kind of for improving the method for CQI report.

As a solution for eliminating the problems referred to above, can be in conflict PUSCH reportIn mode 3-1, consider the method for reporting in addition MU-MIMOCQI. Therefore, allowFlexible dispatching between SU-MIMO and MU-MIMO pattern is with optimization system performance. But,In order to be supported in the dynamic translation between SU-MIMO and MU-MIMO pattern, MU-MIMOMust be attached to SU-MIMOCQI, and must feed back attached result, make to need to useIn the other expense of MU-MIMOCQI feedback.

As another kind of solution, can use new PUSCH Report mode. For example, canTo use PUSCH Report mode 3-2, wherein, transmitting is for first generation code word (CW)WBCQI and for WBCQI, WBW1 and the SBW2 of the 2nd CW. Pass through PUSCHReport mode 3-2, can feed back the PMI for more accurate frequency granularity, makes to improveThe precision of feedback information. Although 3-2 does not need other for PUSCH Report modeMU-MIMOCQI feedback, but feedback overhead increased to improve more accurate PMI feedbackFrequency granularity.

Table 61 below illustrates the PUSCH Report mode 3-1 institute in 4Tx antenna transmissionThe feedback overhead, PUSCH Report mode 3-1 needing and other MU-MIMOCSI are requiredFeedback overhead and the required feedback overhead of PUSCH Report mode 3-2. In table 61, NBe the quantity of subband (SB), and L is used to indicate the required bit of selected subbandQuantity.

[table 61]

Can find out from table 61, at two kinds of CQI report improvement method (MU-MIMOCQILaunching technique and for using the method for PUSCH Report mode 3-2) use feedbackExpense is greater than the feedback overhead using in PUSCH Report mode 3-1. Therefore, on applyingThe CQI report improvement scheme of stating, needs enough performance gains.

Table 62 illustrates for the single CQI in 4 × 2MU-MIMO transmitting and changes to 64The system level performance of kind method. Table 62 to 64 in, only suppose to a UE and assign one deck.In table 62 and 63, the maximum quantity of the UE of MU-MIMO scheduling is set to 2. At tableIn 64, the maximum quantity of the UE of MU-MIMO scheduling is set to 4. For MU-MIMOCQI calculates, and supposes that UE is to search for preferred wave beam with the similar mode of SU-MIMO schemeVector, and predefined other interfering beam vector. Therefore, by a preferred wave beam toMeasure and consider that other interfering beam vector of common-channel interference forms precoder, and,Precoder based on forming is carried out MU-MIMOCQI and is calculated.

Embodiment 14 illustrates for reporting the method detailed for the CSI of multicarrier transmitting, andAnd the transmitting priority that is configured in the feedback information using in multicarrier transmitting, makes to identifyIn the time that conflicting each other, different feedback information numbers to abandon which feedback information. Saying belowIn bright, multicarrier or carrier aggregation represent to configure one or more carrier waves (or one or more clothesBusiness community). , embodiment 14 can be applied to wherein in UE, configure multiple carrier waves (orMultiple communities) situation.

In the CQI/PMI/RI in the cycle for the transmitting of DL multicarrier report, can pass throughIn tradition 3GPPLTE version 8, the higher level configuration parameter of definition comes for each DL carrier waveSet up independently the feedback scheme in cycle.

If set up PUCCH and PUSCH when different, can report use in a subframeCarry the CQI/PMI/RI of wave period in a DL only. Which can assign about to customizing messagesIndividual DL carrier wave reports with the CQI/PMI/RI in cycle the priority being associated. With priority settingExplicitly, can set up according to Report mode or type the priority of carrier wave. If reportPattern/type is mutually the same, for example, sets up the preferential of carrier wave by higher level (, RRC)Level. The configuration of such feedback transmitting priority can not only be applied to wherein do not use PUSCH andThe situation of transmitting feedback, and be applied to the another kind that wherein causes transmitting feedback with PUSCHSituation. Because report, can only for the CQI/PMI/RI of a DL carrier wave in a subframeTo abandon the CQI/PMI/RI of another DL carrier wave. Be associated with a DL carrier wave that will feed backGround, in 3GPPLTE version 8, RI, WBCQI/PMI and the SBCQI of definition rush each otherUnder prominent condition, can configure according to priority (, RI > WBCQI/PMI, WBCQI,SBCQI) carry out transmitting feedback information.

If configure PUCCH and PUSCH when different time without HARQA/N informationSituation under only launch the CQI/PMI/RI in cycle, can be at the bar that can not obtain PUSCHUnder part, launch CQI/PMI/RI by PUCCH. On the contrary, if can obtain PUSCH,Can launch CQI/PMI/RI by PUSCH.

By in the cycle CQI/PMI/RI of PUCCH, can configure above-mentioned variousPUCCH Report mode and PUCCH Report Type.

For 2Tx or 4Tx antenna transmission, can be used as PUCCH Report mode and set up pattern1-0, pattern 1-1, pattern 2-0 or pattern 2-1. For 8Tx antenna transmission, can set up mouldFormula 1-1-1, pattern 1-1-2 and pattern 2-1.

Below detailed description is applicable to the priority of above-mentioned PUCCH Report Type. At single yearIn the CSI report in the cycle on ripple, PUCCH Report Type 3,5 or 6 can have the longestReport circulation. In addition, the RI based on reported, wb the one PMI or PTI determine PUCCHReport Type 1,1a, 2,2a, 2b and 4 feedback information. Therefore, if PUCCH reportAccuse type 3,5 or 6 and conflict with PUCCH Report Type 1,1a, 2,2a, 2b, 2c or 4,Can abandon PUCCH Report Type 1,1a, 2,2a, 2b and the 2c with low priority.

On the other hand, described at embodiment 6, can be with SR, HARQ-ACK, UL-SCH(in the situation that of subframe bundling operation) > RI > WBCQI/PMI, WBCQI, SBCQIOrder arrange to the transmitting priority of the conflict application of multiple control informations. For example, ifSR control information conflicts with CQI/PMI/RI in same subframe, abandons CQI/PMI/RI,And can launch SR.

Based on above-mentioned explanation, below use description to the present embodiment of feedback priority level configuration.

In method 1, can determine feedback priority level based on Report Type.

In method 2, if during the feedback of different DL carrier waves identical Report Type thatThis conflict, can determine feedback priority level according to Report Type.

In method 3, marshalling feedback kind, makes to determine instead according to feedback kind groupFeedback priority.

In method 4, if during the feedback of different DL carrier waves identical Report Type thatThis conflict exists, and CQI/PMI can determine feedback priority level according to Report Type.

Above-mentioned PUCCH Report mode can be by the constituting of Report Type, as belowTable 71 shown in. In table 71, wb is broadband (WB) feedback information, and sb is subband(SB) feedback information, a PMI is that precoding index is (, corresponding to the explanation above-mentionedIn i1 or W2), and the 2nd PMI be precoder index 2(, corresponding to upperState i2 or W2 in bright).

[table 71]

Can as shown in report 72 below, organize into groups according to transmitting circulation and feedback information attributeReport Type.

[table 72]

In table 71, Report Type group A is set or the gathering that comprises the feedback information of RI.Report Type group B is set or the gathering that comprises the feedback information of wb the one PMI. Report typeType group C is set and the gathering that comprises the feedback information of wbCQI. Report Type group D is bagDraw together set or the gathering of the feedback information of sbCQI.

Therefore,, as proposed in said method 3, can come according to Report Type groupDetermine feedback priority level. To describe in detail for the attribute based on each feedback information belowSet up the example of the present invention of priority.

Report off and on RI information. If do not report RI information, RI has quite long reportAccuse circulation, make before next RI report, to apply long (or wrong) order information, leadCause Signal Degrade. Compare with other feedback information, RI can be established as and have high priority.As the group A(that comprises RI as shown at Report Type 3,5 and 6, RI report group) canTo there is the feedback priority level higher than the group that comprises CQI/PMI.

Subsequently, wb the one PMI indicates based on wbCQI/wb the 2nd PMI/sbCQI/sb secondThe customizing messages of selection/calculating of PMI etc. If do not report wb the one PMI, will be subsequentlyThe CQI/PMI information of report has difficulty on selecting/calculating. Therefore, wb the one PMI canTo there is the higher feedback priority level than wbCQI/wb the 2nd PMI/sbCQI/sb the 2nd PMI.Can determine wb the one PMI report circulation by RRC signaling in the following manner: passableIn the circulation of RI information reporting, repeatedly report RI information.

In the time determining the priority of wbCQI and sbCQI information, can consider each reportFrequency and dependence. At the PUCCH feedback model 2-1 for 2Tx and 2Tx antenna transmissionIn, can after the transmitting of wbCQI+wbPMI information, calculate by the wbPMI based on reportSbCQI. Therefore, sbCQI can have the dependence for wbCQI+wbPMI. In addition,SbCQI can be identified as to supplementary to improve performance, and by it than wbCQI more frequentlyLaunch numerously. Therefore, can set up wbCQI to there is the priority higher than sbCQI.As in Report Type 4,2,2b and 2c, comprise the group C(of wbCQI, wbCQIReport group) can have such as the group D(that comprises like that sbCQI in Report Type 1 and 1a,SbCQI report group) higher feedback priority level.

Based on above-mentioned explanation, when different Report Type group A, B, C and D are in identical subframeIn while conflicting each other, can define in every way the excellent of each Report Type group A～DFirst level. Table 73 below illustrates the example of priority configuration.

[table 73]

Ex1	A>B>C>D
		Ex2	A=B>C>D
Ex3	A>B=C>D
		Ex4	B>A>C>D

Referring to the example 1(Ex1 of table 73), comprise that the group of RI has limit priority, and,Can with comprise wb the one PMI group, comprise the group of wbCQI and comprise the group of sbCQIOrder sequentially arrange ensuing priority. At example 2(Ex2) in, comprise the group of RIThere is the priority identical with the group that comprises wb the one PMI, and, to comprise wbCQI'sGroup and comprise that the order of the group of sbCQI sequentially arranges ensuing priority. In example 3(Ex3) in, comprise that the group of RI has limit priority, comprise the combination of wb the one PMIThere is identical priority with the group that comprises wbCQI, and comprise that the group of sbCQI hasLow priority. At example 4(Ex4) in, comprise that the group of wb the one PMI has the highest preferentialLevel, and can with comprise RI group, comprise the group of wbCQI and comprise the group of sbCQIOrder is sequentially arranged ensuing priority.

On the other hand,, can set up according to feedback model described in embodiment 4 as previouslyBe used for the feedback priority level of the feedback information that belongs to same Report Type group.

For example, can have than for 2Tx for the Report mode 2-1 of 8Tx antenna transmission orReport mode 1-0,1-1,2-0 or the 2-1 of 4Tx antenna transmission or for 8Tx antenna transmissionThe priority that Report mode 1-1-1 or 1-1-2 are high. Therefore, can be in a Report Type groupDetermine the priority of independent Report Type.

For example, group A(, comprise the Report Type group of RI) in comprise Report Type 3,5With 6. Can operation report type 6 be configured for the feedback model 2-1 of 8Tx antenna transmission.Can operation report type 3 be configured for 2Tx or 4Tx antenna transmission Report mode 1-0,1-1,2-0 and 2-1. Can operation report type 5 be configured for the report of 8Tx antenna transmissionPattern 1-1-1 and 1-1-2. At the Report mode 2-1 for 8Tx antenna transmission, according toThe PTI value that RI launches is together determined Next Report precoding type. Therefore, RI+PTI canLaunch high priority to have than RI transmitting or RI+PMI.

In addition, group C(, comprise the Report Type group of wbCQI) in comprise Report Type4,2,2b and 2c. Report Type 4,2 and 2b are for the Report mode 2-1 of 8Tx antenna transmission.In addition, Report Type 4,2 and 2b can be for the wbCQI Report modes of 8Tx antenna transmission1-0 and 1-1 and Report mode 1-1-1. In this case, the report using in sbCQI reportAccuse type 4,2 and the always feedback information for reporting subsequently of 2b, making can be toEach Report Type 4,2 or 2b assign high priority. Therefore, although use same typeFeedback information, but can according to which feedback model for transmitting be identified for eachThe priority of feedback information. Therefore, shown in table 74 below, in Report Type group, compriseThe example of priority of each Report Type.

[table 74]

Group	Priority
		A	Type 6 > type 5 > type 3
A	Type 6 > type 5, type 3
		C	For the type 2b of Report mode 2-1 > for the type 2b of Report mode 1-1-1
C	For the type 2 of Report mode 2-1 > for the type 2 of Report mode 1-1
		C	For the type 4 of Report mode 2-0 > for the type 4 of Report mode 1-0

Proposed in addition by the present invention explicitly describing in detail with the configuration of feedback priority level belowEmbodiment.

In method 5, assign unique to each Report Type or each Report Type groupPriority. In the Report Type comprising in same Report Type group, can be according to by for oftenThe RRC of a DL carrier wave configures the priority providing and sets up the priority of each Report Type.

In method 6, to each Report Type or each Report Type group assigned priority,And can configure and be based upon the excellent of the Report Type that comprises in same Report Type group by RRCFirst level.

If as set up Report Type group as shown at table 72 and as in the example 1 of table 73(Ex1) shown in, set up Report Type group priority (, A > B > C > D),Can be based upon in the feedback report of each DL carrier wave according to the priority of Report Type groupThe priority of the independent Report Type using.

For example,, if Report Type 3,5 or 6 and Report Type 1,1a, 2,2a, 2b, 2cOr 4 conflicts, can abandon have low priority Report Type 1,1a, 2,2a, 2b,2c or 4. If Report Type 2a conflicts with Report Type 1,1a, 2,2b, 2c or 4,Can abandon Report Type 1,1a, 2,2b, the 2c or 4 with low priority. If reportType 2,2b, 2c or 4 conflict with Report Type 1 or 1a, can abandon have low preferentialRear a kind of Report Type 1 or the 1a of level.

Next, if as set up Report Type group as shown at table 72 and as at table 73Example 2(Ex2) shown in set up Report Type group priority (, A > B > C > D),Each DL can be based upon multicarrier transmitting according to the priority of Report Type group timeThe priority of the independent Report Type on the feedback report of carrier wave.

For example,, if Report Type 3,5,6 or 2a and Report Type 4,2,2b, 2c, 1Or 1a conflict, can abandon have low priority Report Type 4,2,2b, 2c, 1 or1a. In addition, if Report Type 4,2,2b or 2c conflict with Report Type 1 or 1a, canTo abandon Report Type 1 or the 1a with low priority.

Next, if if set up Report Type group and as showing as shown at table 7273 example 3(Ex3) shown in set up Report Type group priority (, A > B > C> D), each can be based upon multicarrier transmitting according to the priority of Report Type group timeThe priority of the independent Report Type on the feedback report of individual DL carrier wave.

For example,, if Report Type 3,5 or 6 and Report Type 2a, 4,2,2b, 2c, 1Or 1a conflict, can abandon have low priority Report Type 2a, 4,2,2b, 2c,1 or 1a. In addition, if Report Type 2a, 4,2,2b or 2c and Report Type 1 or 1aConflict, can abandon Report Type 1 or the 1a with low priority.

Which will describe in detail for carrier wave having for the cycle in multicarrier transmitting aboutThe above-mentioned explanation of the permanent customizing messages of CSI report. The cycle using in multicarrier transmittingCSI report in, be identified for independently the PUCCH report in cycle for each DL carrier waveThe higher level parameters of accusing, makes to compare and increase significantly report type with single carrier transmitThe quantity of type conflict.

Can see from table 71, suppose for DL emission mode 9 and other emission mode and set upPUCCH Report mode and Report Type. For example,, although in the cycle for single carrier transmitIn CSI report, PUCCH Report Type 1 does not conflict with PUCCH Report Type 2, butIn multicarrier transmitting, PUCCH Report Type 1 may conflict with PUCCH Report Type 2, makesMust need the solution for eliminating such conflict.

In the cycle CSI report for multicarrier transmitting, can be according to the report based on above-mentionedThe priority of pattern is selected DL carrier wave (HuoDL community). But, based on Report modeApply under the hypothesis of the priority of selecting for the DL carrier wave of cycle CQI/PMI/RI report,Can abandon continually the necessary report information number of the DL carrier wave for activating. In addition, withIdentical mode in Report Type conflict, can be according to for cycle CQI/PMI/RI reportRRC configuration rule application DL carrier wave is selected priority. Therefore, if based at multicarrierReport mode when transmitting and apply DL carrier wave select priority, occur fuzzy. On the other hand,Only determine that based on Report Type report priority can prevent from abandoning important feedback information, makesMust be able to easily realize such report priority determines.

Therefore, in table 72, organize into groups Report Type, and can be by excellent the feedback of report set typeFirst level is defined as A > B=C > D. For example, the in the situation that of carrier aggregation, there is Gao YouFirst the Report Type (Report Type 3,5 and 6) of level keeps their priority, and canDetermine DL carrier wave with the order of the priority based on independent Report Type.

Next,, determine by describing in detail the PUCCH report that comprises wb the one PMIThe priority of type 2a.

Figure 34 illustrates the cycle PUCCH Report mode 2-1 for the emission mode 9 of table 71Report circulation. Can configure the cycle of determining emission mode 9 according to Report Type and PTIThe report circulation of PUCCH Report mode 2-1. Referring to Figure 34, Report Type 6(RI+PTI)Can there is report circulation (JK+1) N_pd·M_RI. Referring to Figure 34 (a), in the situation of PTI=0Under, Report Type 2a(wb the one PMI) can there is report circulation MN_pdwhereM＝{2,4}，And N that can be after mission report type 2a_pdTime point place report Report Type 2b(wb theTwo PMI and wbCQI). The in the situation that of PTI=1, Report Type 2b can have reportAccuse circulation (JK+1) N_pd, and N that can be after mission report type 2b_pdThe report of time point placeReport Type 1a(sb the 2nd PMI and sbCQI). Figure 34 illustrates for passing through at M=2The PUCCH Report mode 2-1 of the DL emission mode 9 of the CSI-RS of 8 beamwidths of antenna at placeIllustrative report circulation.

As shown at Figure 34 (a), the in the situation that of PTI=0, Report Type 2a can toolThere is the circulation identical with Report Type 2b. As shown at Figure 34 (b), in the feelings of PTI=1Under condition, the report circulation of Report Type 2a can be than the report circulation much shorter of Report Type 2b.

If easily application wherein has the long Report Type of reporting circulation and has higher priorityPriority rule, Report Type 2b can have the priority higher than Report Type 2a.But, at the code book structure for 8Tx antenna PMI/CQI, Report Type 2a(wbThe one PMI) can comprise long-time spatial channel information, and Report Type 2b(wb secondPMI and wbCQI) relevant more closely to short time spatial channel information. Preferably, reportAccusing type 2a can have than except Report Type 6(RI+PTI) other Report TypeHigher priority. Therefore, at the PUCCH of the emission mode 9 in the time that multicarrier is launchedIn the situation of Report mode 2-1, Report Type 2a can have than Report Type 1,1a, 2,2b, 2c or 4 higher priority.

As mentioned above, below, will describe in detail for the cycle in the time that multicarrier is launchedThe entirety rule of the priority that the DL carrier wave (HuoDL community) of CQI/PMI/RI report is selected.

As the priority which DL carrier wave will be used for CSI feedack about, Ke YijiDetermine the priority of the DL carrier wave being activated in CSI feedback report type. For this object,As shown at table 72, Report Type is categorized as: comprise RI group A(Report Type 3,5 and 6); Comprise wb the one PMI and the group B(Report Type 2a of symbol CQI); CompriseThe group C(Report Type 2 of wbCQI, 2b, 2c and 4); And, comprise the group of sbCQID(Report Type 1 and 1a), and the priority of Report Type group independently can be defined asA > B > C > D. If the priority of Report Type is mutually the same, can be according to being swashedThe priority of the RRC configuration between the DL carrier wave of living determines which DL carrier wave is for CSIFeedback. By this way, can launch the CQI/PMI/RI for determined DL carrier wave,And can abandon the CQI/PMI/RI of different DL carrier waves.

If identical PUCCH Report Type conflicts each other, be reported in by higher level and startDL carrier wave (DL community) between the PUCCH of the DL carrier wave with limit priorityReport Type, and can abandon the CQI/PMI/RI of other DL carrier wave. For example, ifThe CSI of particular point in time x (DL community) #1 using PUCCH Report Type 6 as DL carrier waveTransmitting can suppose using PUCCH Report Type 6 at identical time point x as different DLThe CSI transmitting of carrier wave (DL community) #2. In this case, if for DL carrier wave #1The priority of RRC configuration higher than DL carrier wave #2, can launch for DL carrier wave #1'sPUCCH Report Type 6, and can abandon the PUCCH report for different DL carrier wave #2Accuse type 6.

According to above-mentioned suggestion of the present invention, if the priority of Report Type group is defined as to A > B> C > D, can be (or one or more by being used to indicate in one or more DL carrier wavesOn DL community) which DL carrier wave method that will be used for the priority of CSI transmitting be expressed as follows.

If PUCCH Report Type 3,5 or 6 and PUCCH Report Type 1,1a, 2,2a, 2b, 2c or 4 conflicts, can abandon rear a kind of PUCCH report with low priorityType (1,1a, 2,2a, 2b, 2c or 4).

If PUCCH Report Type 2a and PUCCH Report Type 1,1a, 2,2b, 2cOr 4 conflict, can abandon have low priority rear a kind of PUCCH Report Type (1,1a, 2,2b, 2c or 4).

If PUCCH Report Type 2,2b, 2c or 4 and PUCCH Report Type 1 or1a conflict, can abandon rear a kind of PUCCH Report Type 1 or the 1a with low priority.

If identical PUCCH Report Type conflicts each other, report has by activatingDL carrier wave (DL community) between the PUCCH report of the limit priority set up of higher levelAccuse type, and can abandon the CQI/PMI/RI for other DL carrier wave.

On the other hand, can find out from table 72, Report Type is categorized as to the group A that comprises RI(Report Type 3,5 and 6), comprise wb the one PMI and there is no the group B(report of CQIAccuse type 2a), comprise group CI(Report Type 2,2b, the 2c and 4 of wbCQ) and compriseGroup D(Report Type 1 and the 1a of sbCQI). Below will describe in detail and work as based on Report TypeWhile deciding the priority of the DL carrier wave being activated for other of Report Type group priorityThe present embodiment of configuration.

In one embodiment, if the priority of Report Type group is defined as to A=B > C=D, if Report Type 3,5,6 or 2a and Report Type 4,2,2b, 2c, 1 or 1a punchingProminent, can abandon the Report Type 4,2,2b, 2c, 1 or 1a with low priority. AsThe priority of fruit PUCCH Report Type is mutually the same, can be according to the DL carrier wave activatingThe priority of the RRC configuration between (DL community) is determined feedback priority level. Can abandonThe CQI/PMI/RI of other DL carrier wave.

In another embodiment, if the priority of Report Type group is defined as to A > B > C=D, if PUCCH Report Type 3,5 or 6 and PUCCH Report Type 2,2a, 2b,2c, 4,1 or 1a conflict, can abandon have low priority PUCCH Report Type 2,2a, 2b, 2c, 4,1 or 1a. In addition, if PUCCH Report Type 2a and PUCCHReport Type 2,2b, 2c, 4,1 or 1a conflict, can abandon the PUCCH with low priorityReport Type 2,2b, 2c, 4,1 or 1a. If the priority of middle Report Type is mutually the same,Can be according to the priority of the RRC configuration between the DL carrier wave being activated (DL community)Determine feedback priority level. Can abandon the CQI/PMI/RI of other DL carrier wave.

In embodiment 14, can the cycle CSI of PUCCH will be used in multicarrier configurationThe said method of the priority of report is expressed as follows.

First,, if assign one or more Serving cells to UE, UE can be anyIn given subframe, transmitting is used for the only channel condition information of a Serving cell (CSI).

In any subframe, if according to the feedback information of feedback information attribute first service communityThere is the priority higher than second service community, can abandon and there is second of lower priorityThe feedback information of Serving cell.

For example,, below with reference to the example 2(Ex2 of table 73) report based on table 70 describedThe priority of the CSI feedback information of type (or PUCCH Report Type).

In any subframe, if the PUCCH Report Type of a Serving cell 3,5,6Or the PUCCH Report Type 1 of 2a and another Serving cell, 1a, 2,2b, 2 or 4 punchingsProminent, can abandon there is lower priority rear a kind of CSI(, PUCCH Report Type1 or 1a).

In any subframe, if PUCCH Report Type 2,2b, the 2c of a Serving cellOr 4 conflict with PUCCH Report Type 1 or the 1a of another Serving cell, can abandonThere is rear a kind of CSI(of lower priority, PUCCH Report Type 1 or 1a).

If there is the difference service of equal priority PUCCH Report Type in any subframeThe CSI report section of community conflicts each other, reports that special services community (, has basisThe Serving cell of the high priority of RRC configuration, for example, has the clothes of minimum service cell indexBusiness community) CSI, and can abandon the CSI of remaining Serving cell.

Figure 35 is the flow chart of diagram for the method for transmitting channel state information. Below with reference toFigure 22 describes the side for reporting channel status information (CSI) according to the embodiment of the present inventionMethod.

With from BS(or eNB) launch explicitly to the DL of UE, UE measures DL channelState, and feed back measurement result by up-link. For example,, if sent out to the DL of BSPenetrate 8 Tx antennas of application, BS can pass through 8 antenna ports (antenna port index 15-22)Launch CSI-RS(channel condition information-reference signal). UE can send out by CSI-RSPenetrate DL channel status measurement result (RI, PMI, CQI etc.). Above-mentioned each of the present invention showsExample can be applied to the method detailed for selecting/calculate RI/PMI/CQI. BS can basisThe channel condition information (RI/PMI/CQI) receiving is determined quantity, the precoding of DL emission layerDevice and MCS(modulation compilation scheme) level etc., make it can launch DL signal.
