Description

A kind of Notification Method and device of Physical Uplink Control Channel Power Control signaling

Technical field

The present invention relates to the communications field, in particular to a kind of Physical Uplink Control Channel (Physical Uplink Control Channel, abbreviation PUCCH) Power Control signaling Notification Method and device.

Background technology

Long evolving system (Long Term Evolution, abbreviation LTE) defines PDCCH (Physical Downlink control channel, Physical Downlink Control Channel) dispatching distribution and other control information are carried, each PDCCH is made up of several CCE (Control Channel Element, control channel unit), the CCE numbers of each subframe Determined by PDCCH quantity and downlink bandwidth.

UE (user equipment) by search space blind Detecting obtain PDCCH, search space is divided into public search space With UE dedicated search space, public search space refers to the region that all UE can be searched, and what this space carried is cell Proprietary Information.Dedicated search space is the spatial dimension that single UE can be searched, and multiple UE dedicated search space is possible to weight Folded, simply general initial searching position is different.Before blind check, UE mode of operations are notified and for PDCCH's by high-level signaling Radio Network Temporary Identifier (the Radio of CRC (Cyclic Redundancy Check, abbreviation CRC) scrambling Network Temporary Identity, abbreviation RNTI) type.

Search spaceWith aggregation level L and candidate's PDCCH quantity M^(L)Between relation be shown in Table 1.Aggregation level is PDCCH CCE number of occupancy.When carrying out blind Detecting in user's dedicated search space, user equipment identifies (UE ID) according to user first Blind check initial position Y is calculated with subframe numbers etc._k, then detected in search space, oneself given until detecting Untill PDCCH.

Table 1.PDCCH Candidate Sets

The correspondence of relative position of the first control channel unit of aggregation level and PDCCH in user's dedicated search space Relation is shown in Table 2.Relative position of the first control channel unit of PDCCH in user's dedicated search space refers to PDCCH occupancy First CCE indexes n_CCEWith blind check initial position Y_kRelative position, use n herein_{CCE, offset}Represent, n_{CCE, offset}=n_CCE- Y_k, n_{CCE, offset}Span be 0~6,8,10.

The aggregation level of table 2 and the corresponding relation of first CCE position

LTE uplink physical channel include Physical Random Access Channel (Physical Random Access Channel, Abbreviation PRACH), Physical Shared Channel (Physical uplink shared channel, abbreviation PUSCH), physical uplink control Channel (Physical Uplink Control Channel, abbreviation PUCCH) processed.

In LTE R8/R9/R10 protocol versions, PUCCH channel formats can be divided into three major types, totally seven kinds：The first kind includes Three kinds of forms, i.e. format1, format1a, format1b, the second class equally also include three kinds of forms, i.e. format2, Format2a, format2b, the 3rd class include a kind of form format3.First kind PUCCH asks for transmitting and scheduling (Scheduling Request, abbreviation SR) and confirm (Acknowledgement, abbreviation ACK)/non-acknowledgement (Negative Acknowledgement, abbreviation NACK) signaling.Second class PUCCH is mainly used in transmitting channel state information (Channel State Information, abbreviation CSI).3rd class PUCCH is mainly used in transmitting multiple ACK/NACK under carrier aggregation scene Signaling.

In LTE R8/R9/R10 protocol versions, the corresponding PUCCH channel of a user equipment, believe for PUCCH Road, different UE can be carried out by the mode of code division multiplexing (Code Division Multiplexing, abbreviation CDM) in cell Multiplexing, i.e., using different cyclically shifted sequences (CS) or different orthogonal code (OC).Here different cyclically shifted sequences refer to Be different cyclic shifts corresponding to same root sequence.Root sequence is the CG-CAZAC (Computer- of length=12 Generated Constant Amplitude Zero Auto-Correlation, the constant amplitude zero auto-correlation of computer generation) Sequence, it is orthogonal between the different cyclic shifts of same root sequence, it is nonopiate between different root sequences.According to current PUCCH signalings Collocation method, PUCCH sequence group # are determined by cell ID, therefore PUCCH root sequence corresponds with cell ID.Cause This, achievable orthogonal between the PUCCH in same cell, when cell ID is different, minizone PUCCH is nonopiate.

In Rel-10 version LTE protocols, uplink power control be mainly used in compensate channel path loss (Path Loss, Abbreviation PL) and shadow fading, and for suppressing inter-cell interference.When subframe i sends PUCCH to serving cell c, transmit power Control process formula is：

The unit of above formula is dBm, wherein,

P_{CMAX, c}(i)：The maximum allowable transmit power determined by UE power grade.

h(n_CQI, n_HARQ, n_SR) it is the value related to PUCCH format, determined by the PUCCH specifying information bit numbers carried.

P_{O_PUCCH}：Represent to meet that channel passes when considering path loss impacts (assuming that in base station side UE) on this carrier wave Defeated UE when requiring minimum emissive power, P_{O_PUCCH}=P_{O_NOMINAL_PUCCH}+P_{O_UE_PUCCH}, wherein,

P_{O_NOMINAL_PUCCH}：It is the parameter proprietary for determining the cell of UE minimum emissive powers, to institute in same cell There is UE that identical value is set, by proprietary (cell-specific) RRC of cell (Radio Resource Control, wireless money Source controls) signal, span：[- 127, -96]；It is the amount (cell specific) related to cell, to same All UE set identical value in cell, and scope is [- 126,24] dBm, and granularity is 1dB, it is possible to is represented with 8bit.

P_{O_UE_PUCCH}：It is the parameter proprietary for determining the user of UE minimum emissive powers, by the proprietary (UE- of user Specific) RRC signaling notifies, span：[- 8,7].

Δ_{F_PUCCH}(F)：It is the bias relative with PUCCH format 1a, is notified by the proprietary RRC signaling of cell, it is right Answer different PUCCH formats to have different values, configured by high level.

Δ_TxD(F’)：Notified by the proprietary RRC signaling of user whether launched by PUCCH using transmitting diversity mode The parameter value of decision；

G (i) is UE close-loop power control parameters, according to RRC and TPC (Transmission Power Control, transmission Power Control) synthesis obtain, have accumulation and current absolute value two types, this parameter is closed-loop power control and minizone in cell The synthesis result of power control.

PL_cIt is the downlink path loss value calculated on this carrier wave, is lost and estimates for up path.UE is descending by measuring Path loss obtains.Pilot signal power and base station that UE is received by calculating are indicated to UE pilot transmission work(by signaling The difference of rate can be obtained by downlink path loss value, and the above-mentioned path loss values being calculated are used as into upward signal power Path loss compensation during control.

Path loss estimation formula can be expressed as：

PL=referenceSignalPower-higher layer filtered RSRP,

Wherein, referenceSignalPower is the cell common reference signal power configured by high-level signaling；

Higher layer filtered RSRP are the connecing by high-rise filtered reference signal that UE terminations receive Receive power (Reference Signal Received Power, abbreviation RSRP).

Cooperative multipoint transmission (Coordinated Multi Point Transmission/Reception, abbreviation CoMP) Technology is to realize at cell edge the higher capacity of Radio Link and reliable using the transmitting antenna cooperation transmission of multiple cells Transmission, can effectively solve cell edge interference problem.CoMP technologies are divided into DL CoMP (down collaboration multi-point) and UL CoMP (uplink coordinated multicast communication) technology, it both can largely improve the average spectral efficiency (ase) and cell of cell The service quality of edge customer.

Under CoMP scenes, up-downgoing node can be selected independently, wherein, descendant node selects according to receiving power, Downlink reception quality can be ensured, upstream node is selected according to path loss, and such UE can save power overhead, therefore is existed upper The inconsistent situation of descendant node, and upstream node may be transparent to UE, will cause the ginseng according to the transmission of descending sending node It is not larger to the PL value differences between UE to examine the uplink receiving node of PL values that signal estimates and reality, uses downlink estimation PL values out compensate come the transmit power of the UE sides signal to up-link, will result in UE end signal transmission powers and estimate Inaccurate, the waste UE transmission powers of meter, increase UE battery losses, influence the reception of UE upward signal and increase to other use The interference at family.Meanwhile under CoMP scenes, upstream node may be in multiple minizone switching at runtime, therefore ascending power also needs Dynamically to adjust.

In existing Rel-10 standards, power adjustment can be carried out according to TPC, but because this is a kind of fine setting means, it is adjusted Synchronizing length is shorter, it is necessary to which base station repeatedly issues closed loop power control command instruction UE is adjusted just up path can be lost Error compensation is returned, and expense is larger, and the time is longer so that UE is sent out in longer period of time with inappropriate power Penetrate, UE ascending power cannot be utilized rationally, and increase the interference to other users.

In view of the above-mentioned problems, each company proposes several schemes at present：

Scheme one, proprietary path loss biasing (pathloss offset) PL of user_offset, i.e.,

P_PUCCH(i)=min { P_{CMAX, c}(i), P_{0_PUCCH}+PL_c+PL_offset+h(n_CQI, n_HARQ, n_SR)+Δ_{F_PUCCH}(F)+Δ_TxD (F’)+g(i)}[dBm]；

Scheme two, the proprietary road loss compensation factor α for PUCCH of user, i.e.,

P_PUCCH(i)=min { P_{CMAX, c}(i), P_{0_PUCCH}+αPL_c+h(n_CQI, n_HARQ, n_SR)+Δ_{F_PUCCH}(F)+Δ_TxD(F’)+g (i)}[dBm]；

Scheme three, the P of enhancing_{O_PUCCH}, that is, expand P_{O_PUCCH}Span；

Scheme four, the proprietary reference signal power of user (referenceSignalPower), i.e.,：

Path loss：PL_c=UE-specific referenceSignalPower-higher layer filtered RSRP；

Scheme five, the proprietary power offset parameter of user (Poweroffset), i.e.,

Path loss：PL_c=referenceSignalPower-higher layer filtered RSRP+ Poweroffset。

Meanwhile the UE that up-downgoing node is inconsistent, the parameter according to descendant node is sent into PUCCH, if up-downgoing The cell ID (cell ID) of node is different, nonopiate between the PUCCH in the PUCCH and upstream node of transmission, between each other Interfere, influence receptivity.Have at present with the solution of proposition, scheme one, the scheme of multiple resource areas, for example, The inconsistent UE of up-downgoing node is configured in a newly-increased resource area, other UE are put into traditional resource region.It is newly-increased Resource area can be biased by UE-specific resourceTo realize, even resource indexScheme two, UE-specific roots sequence and CS hopping schemes, can be by setting UE-specific virtual subdistricts ID is put to realize, such as sets the cell ID that virtual subdistrict ID is equal to upstream node, makes up-downgoing section The inconsistent UE's of point is calculated PUCCH using virtual subdistrict ID and sends parameter, can thus realize with upstream node Other UE between it is orthogonal；Scheme three, the combination of the first two scheme, i.e., the user device configuration that needs strengthen to newly spending more money on Source region, while to the user equipment distribution virtual subdistrict ID in newly-increased region, the user equipment in newly-increased region is allowed using virtual small Area ID be calculated PUCCH send parameter, so can both ensure enhancing UE between orthogonality, can ensure again enhancing UE and Orthogonality between the UE not strengthened.

The UE inconsistent to up-downgoing node, PUCCH enhanced scheme and the enhanced scheme of PUCCH power controls can be combined Consider, in addition, during using above-mentioned PUCCH power controls enhanced scheme, required parameter is notified to UE, mesh using what kind of signaling method It is preceding also without certain standardization.
