Description
Technical field
The present invention relates to the control technology of discontinuous transmission (DTX) in time division duplex (TDD) system/discontinuous reception (DRX) activation moments, relate in particular to a kind of control method and device of activation moments.
Background technology
In order to improve message transmission rate, introduced high speed downlink packet access (HSDPA in the TDD system, High Speed Downlink Packet Access) technology and high speed uplink packet insert (HSUPA, HighSpeed Uplink Packet Access) technology.
Wherein, the data transmission procedure of HSDPA is: the base station is by the High-Speed Shared Control Channel (HS-SCCH in the down control channel, Shared Control Channel for HS-DSCH) sends control signaling, control informations such as the physical resource that takies to terminal notice high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH, High Speed Physical DownlinkShared Channel), transformat; Terminal after correctly having received described control information on the HS-SCCH, downlink data receiving on described physical resource; After terminal is decoded to described downlink data, on corresponding high-speed shared information channel (HS-SICH, Shared InformationChannel for HS-DSCH), feed back.
In the transmission course of above-mentioned HSDPA, the timing relationship between HS-SCCH and the HS-PDSCH is by preset parameters n
HS-SCCHDecision, n
HS-SCCHUnit be generally time slot, represent the slot time between last HS-SCCH and first HS-PDSCH.For example, in low spreading rate (LCR) TDD system, n
HS-SCCH〉=3 time slots (time slot), promptly HS-PDSCH and HS-SCCH in same subframe or HS-PDSCH in the next subframe of HS-SCCH, HS-PDSCH and the HS-SCCH position relation in subframe is as shown in Figure 1.
The transmission course of HSUPA is divided into two kinds of scheduled transmission and non-scheduled transmission, and wherein, the scheduled transmission process is: when terminal need send upstream data, send the scheduling of resource solicited message to the base station; Scheduling of resource is carried out according to the solicited message of receiving in the base station, and goes up the transmission resource license information in E-DCH absolute grant channel (E-AGCH, E-DCHAbsolute Grant CHannel); Terminal sends corresponding uplink strengthening data by E-DCH physical uplink channel (E-PUCH, E-DCH Physical Uplink CHannel) on the resource of resource license information appointment; Afterwards, terminal is according to the feedback of the E-PUCH that sets with the timing relationship that strengthens ascending HARQ answering indication signal channel (E-HICH) reception base station in corresponding Transmission Time Interval (TTI), and described feedback is carried on the E-HICH.Wherein, the timing relationship of E-PUCH and E-HICH is by the n of high level configuration
E-HICHDecision is because the n of LCR TDD
E-HICHValue is 4 to 15 time slots, supposes E-PUCH at subframe n, illustrates that then the feedback of E-HICH can be at subframe n or n+1 or n+2, and the timing relationship of E-PUCH and E-HICH can be as shown in Figure 2.And, in the scheduled transmission process,, just will continue to monitor the one group E-AGCH of network side for its appointment as long as terminal has upstream data to need to send.
Non-scheduled transmission process is specially: network side is a terminal distribution ascending physical signal resource by high-level signaling, after terminal receives described signaling, does not need to wait for the scheduling of base station, and directly sends upstream data on the E-PUCH of described ascending physical signal resource indication; Afterwards, terminal is according to E-PUCH that sets and the timing relationship n of E-HICH
E-HICHIn corresponding TTI, receive the feedback of base station.Identical with the scheduled transmission process, described feedback is carried on the E-HICH.
For network side is that the ascending physical signal resource of terminal distribution is exemplified below: for example, for LCR TDD (1.28Mcps TDD), described network side is the following resource allocation parameters of terminal configuration: time interval resource relevant information (TRRI, Timeslot Resource Related Information), activationary time (ActivationTime), subframe numbers (Subframe number), repetition period (Repetition period) and repeat length (Repetition Length).Wherein, the time interval resource relevant information adopts the mode of bit mapping to indicate in five ascending time slots which to distribute to non-scheduled transmission; Activationary time is Connection Frame Number (CFN, Connection Frame Number), and span is 0,1 ... 255.The unit of CFN is a radio frames, and for 1.28Mcps TDD, each radio frames is divided into two subframes again, and the TTI of E-DCH is exactly a subframe, which subframe among the subframe numbers indication CFN that network side disposed; Repetition period and repeat length all are unit with TTI, and the value of repeat length is 0 ..., repetition period-1.Describe below by concrete example.Suppose that network side is that the resource allocation parameters of terminal configuration is as follows: ActivationTime=1, Subframe number=1 (second subframe among the CFN), Repetition period=4, Repetition Length=1, TRRI indicates the 3rd ascending time slot, and then the non-scheduling resource of Fen Peiing is as shown below, here for simplicity, five ascending time slots that only draw in the subframe, as shown in Figure 3.
The research contents of HSPA+ is for optimizing the support to real-time small data packets VOIP business, and for this class business, the signaling consumption of HS-SCCH is excessive, therefore can use for reference the HS-SCCH-less operation of FDD, reduces the expense of HS-SCCH.Transmission method is: network side is the HS-PDSCH physical resource that terminal distribution is monitored, and each TTI of terminal receives the decode the physical resource of distribute of monitoring.
The important research contents of in HSPA+ another is to save terminal electric quality, therefore, has introduced DTX and DRX operation.At present, DTX that is proposed and DRX scheme are: introduce the DRX operation of the DTX and the HS-SCCH of non-scheduling E-PUCH, and make them harmonious.Specifically, in the DTX of non-scheduling E-PUCH operation, can dispose a timer T1 in terminal, terminal periodically sends data with a predetermined cycle on E-PUCH, and receives corresponding E-HICH, keeps to guarantee uplink synchronous.This timer T1 can be set to the integral multiple of non-scheduling E-PUCH channel frame assignment period.In the DRX of HS-SCCH operation, the base station enters into the DRX accepting state by the form notice terminal of physical layer command.DRX also needs the predefine one-period usually, and in order to reduce the power consumption of terminal as much as possible, generally the cycle with DRX is provided with consistent with activation moments.In addition, a timer T2 is set also in the base station generally, the cycle of this timer and startup are constantly in full accord with the timer T1 of above-mentioned end side.If end is at the DRX state, the base station sent control information on corresponding HS-SCCH channel at certain terminal according to the moment of timer T2 appointment.
As seen from the above description, there is following problem for above-mentioned DTX and DRX operation:
DTX and DRX adopt the mode of timer, can occur understanding differently of network side and terminal in some cases and cause, and also are that the activation moments of definite activation DRX operation of network side and end side or DTX operation is inconsistent.In addition, the activation moments of DTX operation and DRX operation is placed in the TTI, in fact, as long as E-PUCH and E-HICH be not in (son) frame, terminal need receive HS-SCCH except the activation moments in the DRX operation so, in the TTI that timing relationship is determined, also need to receive again E-HICH, well do not reach purpose of power saving.In addition, HS-SCCH has only been considered in descending DRX operation, and terminal still needs continue monitoring to down channel E-AGCH, therefore, does not really reach and makes the terminal purpose of power saving.

Below, be described with reference to the accompanying drawings the realization of activation moments control method of the present invention and device by specific embodiment.
In the following description, high level is upper layer node RNC etc. for example of base station, and network side then comprises high level and base station.Discontinuous operation comprises that described down control channel comprises HS-SCCH and E-AGCH for the DTX of non-scheduling E-PUCH operation, for the DRX operation of down control channel and for the DRX operation of HS-PDSCH.Active information comprises: cycle, subframe numbers and the initial activation moment etc. that discontinuous operation is corresponding.
Fig. 4 is the control method schematic flow sheet of the present invention for the DTX activation moments of non-scheduling E-PUCH, and as shown in Figure 4, this method comprises:
Step 401: terminal configuration non-scheduled transmission, when high level determine to activate DTX operation for non-scheduling E-PUCH, determine the cycle of DTX, and with described cycle notice terminal and base station.
Wherein, during the cycle of high-rise definite described DTX, determine according to factors such as type of service, data volume and network loads.After determining, high level can be by high-level signaling or physical control channel notice terminal and described cycle of base station.
In addition, how high level determines to activate the DTX operation can be used correlation technique of the prior art to finish, and repeats no more here.
Step 402: terminal and base station receive all after dates of described DTX, determine the initial activation moment of DTX separately, and each follow-up activation moments.
Wherein, terminal and base station determine that the concrete grammar of DRX activation moments can be the activation moments of determining DTX according to the non-scheduling resource configuration parameter.For example, with the TTI at first non-scheduling E-PUCH resource place as the initial activation of DTX constantly, and follow-up activation moments is determined constantly by DTX cycle and initial activation.Further, when the repeat length of non-scheduling resource of configuration is not equal to 0, i.e. resource of having distributed a plurality of TTI in repetition period, the activation moments of DTX can only be got a TTI in the repetition period, in this TTI, if what distribute is the resource of a plurality of time slots, can also further only get a time slot so.
In addition, this step in the specific implementation process, when with first TTI of non-scheduling resource configuration as the initial activation of DTX constantly the time, terminal and base station can use formula (1) to calculate each activation moments of DTX operation:
[2×(CFN-ActivationTime)+subframenumber-S]％DTX_cycle＝0(1)
DTX_cycle wherein represents the cycle of DTX; S is the pairing subframe numbers of activation moments, and then each activation moments of DRX operation is S subframe in CFN the radio frames that satisfies (1) formula.In actual applications, general respectively with 0 and 1 first of representing in the radio frames and second subframe.
Wherein, when determining that by terminal and base station initial activation constantly, must guarantee terminal and the identical definite strategy of base station use, thereby guarantee that the initial activation of determining in terminal and base station is constantly consistent.
Step 403: at each corresponding activation moments, terminal sends upstream data on the E-PUCH of high level indication, and according to the timing relationship n of E-PUCH and E-HICH
E-HICH, the feedback of reception base station on corresponding E-HICH.
In the control method shown in Figure 4, the initial activation of DTX operation also can be finished by high level constantly, afterwards, directly notify terminal and base station, high-rise determine that terminal and base station determine that the method and the principle in the initial activation moment can be identical in initial activation method constantly and principle and the step 402, repeat no more here.
Fig. 5 is the control method schematic flow sheet of the present invention for the DRX activation moments of down control channel, and as shown in Figure 5, this method comprises:
Step 501: no matter scheduled transmission or non-scheduled transmission, when high level determine to activate DRX for down control channel, determine the cycle and the initial activation moment of DRX, and cycle and the initial activation of above-mentioned DRX waited DRX active information notice terminal and base station constantly.
Wherein, high level can be by high-level signaling or physical control channel notice terminal and the described information in base station.
The high-rise cycle of determining DRX and initial activation be constantly the time, preferably with moment of terminal monitoring down control channel E-AGCH and HS-SCCH as far as possible and the moment of monitoring E-HICH be arranged in same TTI.Concrete grammar can for: according to the timing relationship between non-scheduling resource configuration parameter and E-PUCH and the E-HICH, determine the subframe at the employed E-HICH of the feedback place of non-first TTI of scheduling E-PUCH, as the initial activation of DRX constantly with this subframe; Perhaps, directly as the initial activation of DRX constantly with first TTI of non-scheduling E-PUCH.
Wherein, how high level determines that the DRX that activates for down control channel can use correlation technique of the prior art to finish, and repeats no more here.
Step 502: after terminal and base station receive described DRX active information, determine each activation moments of DRX separately.
Wherein, initial activation constantly can be represented with for example CFN number and a subframe numbers, be designated as DRX_Activation_CFN and DRX_subframe_number respectively, then based on the moment described in the step 501 with terminal monitoring down control channel E-AGCH and HS-SCCH, be arranged in the principle of same TTI with the moment of monitoring E-HICH as far as possible, each activation moments of DRX is the S work song frame that satisfies among the CFN of following formula: [2 * (CFN-DRX_Activation CFN)+DRX_subframe_number-S] %DTX_cycle=0, wherein, DTX_cycle is the DTX cycle.
Step 503: at each corresponding activation moments, terminal is downlink data receiving on corresponding downstream control channel HS-SCCH and/or E-AGCH.
Wherein,, terminal can be set, perhaps, terminal also can be set monitor corresponding HS-SCCH and E-AGCH simultaneously at each activation moments at each activation moments corresponding monitoring HS-SCCH or E-AGCH according to practical application.
Further, when terminal configuration during non-scheduled transmission, step 501 cycle that also can only determine DRX on the middle and senior level, the initial activation of DRX is then determined by terminal and base station constantly, control method determines that with principle and the high level described in Fig. 5 described initial activation method and principle constantly is identical, repeats no more here.
In addition, in step 501, the active information of high-rise notice terminal and base station can also be DRX cycle and DRX subframe numbers, afterwards, terminal and base station are in step 502, and ((2 * connexon frame number+DRX subframe numbers-S) each activation moments of DRX is calculated in %DRX cycle=0 for %DRX cycle=0 of 2 * connexon frame number-DRX subframe numbers+S) or formula according to formula.Wherein, the subframe numbers same meaning in meaning that the DRX subframe numbers is represented and the prior art in the non-scheduling resource configuration parameter, all the previous subframe or a back subframe of radio frames used in indication.Perhaps, the DRX subframe numbers also can replace with information such as DRX side-play amount, can finish control method shown in Figure 5 equally.
In addition, for the HS-SCCH-less operation down, during terminal monitoring HS-PDSCH physical resource, also can use the DRX operation, be illustrated in figure 6 as the present invention for the HS-SCCH-less operation down, for the DRX activation moments control method schematic flow sheet of HS-PDSCH, this method comprises:
Step 601: during the high-rise DRX operation of determining to activate for HS-PDSCH, determine to monitor cycle of DRX operation of HS-PDSCH physical resource and initial activation constantly, and above-mentioned DRX active information is sent to terminal and base station.
Step 602: each activation moments of DRX operation is separately determined according to described active information in terminal and base station.
When determining the activation moments of DRX operation, the activation moments of DRX also can independently be adjusted in the base station, promptly adjusts the cycle and the initial activation moment of DRX, and by the signaling terminal, afterwards, data transmit-receive is carried out at the new DRX activation moments of adjusting in terminal and base station.
