Embodiment
Fig. 1 illustrates the mobile communication system comprising base station and subscriber equipment.Physical channel between subscriber equipment and base station can be divided into downlink channel and uplink channel.Downlink channel comprises physical down link sharing channel (PDSCH, Physical Downlink Shared Channel) for bearing downlink link shared channels (DL ?SCH, Downlink Shared Channel) and paging channel (PCH, Paging Channel), and uplink channel comprises physical uplink control channel (PUCCH, Physical Uplink ControlChannel) for carrying the feedback information in response to downlink transmission, dispatch request (SR, and channel quality indicator (CQI SchedulingRequest), Channel Quality Indicator).
Fig. 2 illustrate LTE ?the frame structure of TDD system.In this example, a radio frames (radio frame), i.e. system-frame, length be such as 10ms, and each radio frames is divided into two length is the field of 5ms.Each field comprises the time slot and 3 special domain that 8 length are 0.5ms; i.e. descending pilot frequency time slot (DwPTS; Downlink Pilot frequency Time Slot), protection interval (GP; Gap of Protection;) and uplink pilot time slot (UpPTS, Uplink Pilot frequency Time Slot).As shown in the figure, each radio frames is made up of 10 subframes (subframe), and these 10 subframes comprise 2 special subframes and each special subframe is made up of above-mentioned 3 special domain.In this example, the length of 3 special domain is 1ms.In one example, chronomere Ts=1/ (15000 × 2048) second.
LTE ?TDD on same carrier wave by time separated transmission and receive channel, therefore can have the frame structure of different uplink/downlink configurations.Table 1 illustrate 7 kinds of different LTE ?the configuration of TDD uplink/downlink, wherein, D represents descending sub frame, and U represents sub-frame of uplink, and S represents the above-mentioned special subframe comprising 3 special domain.
Table 1
As shown in table 1, for LTE ?TDD uplink/downlink configuration 2, have subframe 2 and 7 for ul transmissions in 10 subframes in 1 frame (i.e. system-frame), subframe 0,3,4,5,8,9 is for downlink transmission, and subframe 1 and 6 is for the transmission of special subframe.
In LTE version, such as Rel ?8/9, open down link association index in following table 2, illustrate wherein sub-frame of uplink n and descending/special subframe n ?the associating of k.Particularly, complete to descending/special subframe n ?k decoding after, by sub-frame of uplink n to base station feedback this descending/special subframe n ?k transmission data the need of the signaling be retransmitted.Table 2 shows the value of k, and it depends on the uplink and downlink configuration of mobile communication system and concrete subframe numbers n.
Table 2
As shown in table 2, for LTE ?the value of TDD uplink/downlink configuration 2, k be 8,7,4,6, namely sub-frame of uplink 2 feeds back the 8th, 7,4,6 descending/special subframe before.Such as, for sfn(System Frame Number, system frame number)=m, subframe(subframe)=the sub-frame of uplink of 2, feedback/special subframe descending with following associates:
（sfn=m‐1，subframe=4），
（sfn=m‐1，subframe=5），
（sfn=m‐1，subframe=8），
（sfn=m‐1，subframe=6）；
For sfn(System Frame Number) sub-frame of uplink of=m, subframe=7, feedback/special subframe descending with following associates:
（sfn=m‐1，subframe=9），
（sfn=m，subframe=0），
（sfn=m，subframe=3），
（sfn=m，subframe=1）。
Fig. 3 illustrate for LTE ?TDD uplink/downlink configuration 2, sub-frame of uplink with in feedback window descending/the associating of special subframe.
In LTE version, such as Rel ?8/9, define a kind of multiplexing ACK/NACK feedback model.This pattern utilizes different PUCCH(physical uplink control channel) different modulation symbols represents the feedback states be made up of the feedback information of descending/special subframe on channel and this channel.Particularly, for LTE ?TDD uplink/downlink configuration 2, multiplexing ACK/NACK feedback model uses the index of PUCCH channel and the 2bit information b (0) of PUCCH format 1b and b (1) to represent feedback states, and this is also referred to as PUCCH format 1b Channel assignment (PUCCH format1b channel selection).Feedback information comprises: ACK, NACK and DTX(Discontinuous Transmission, discontinuous transmission).
As mentioned above, for LTE ?TDD uplink/downlink configuration 2, need to feed back 4 descending/special subframes in 1 sub-frame of uplink, as shown in Figure 3.Table 3 be LTE Rel ?ACK/NACK multiplexing transmission mapping form in 8/9.In this form, feedback information (namely, HARQ ?ACK, HARQ is replied) HARQ ?ACK (0), HARQ ?ACK (1), HARQ ?ACK (2), HARQ ?4 the descending/special subframes of ACK (3) respectively in corresponding feedback window.Feedback window refer to be associated with same sub-frame of uplink multiple descending/special subframe.In the table,
represent the PUCCH channel resource selected, and 2bit information b (0) and b (1) is for the formation of different modulation symbols.Be understandable that table 3 can be used to any compatible LTE Rel ?8/9 Rel ?10 and above system in.
Table 3
2 are configured to, when downlink transmission uses normal cyclic prefix pattern at LTE ?TDD uplink/downlink, special subframe is configured to 0 or 5, or when downlink transmission uses extended cyclic prefix pattern, when special subframe is configured to 0 or 4, when all descending sub frames of the feedback window transmitted at physical down link sharing channel are all by decoding success, following feedback information will be generated:
HARQ‐ACK(0)=ACK，
HARQ‐ACK(1)=ACK，
HARQ‐ACK(2)=ACK，
HARQ‐ACK(3)=DTX。
With reference to Fig. 3, for the sub-frame of uplink 2 of sfn=m, these feedback informations correspond respectively to sfn=m ?1 feedback window in subframe 4,5,8,6.Can see, now will feed back DTX(Discontinuous Transmission for special subframe 6).This is because take on a different character sub-frame configuration and different cyclic prefix modes special subframe in descending pilot frequency time slot there is specific length, as shown in table 4 below.When under normal cyclic prefix pattern, special subframe is configured to 0 or 5, or when under extended cyclic prefix pattern, when special subframe is configured to 0 or 4, descending pilot frequency time slot can not be used to physical down link sharing channel transmission due to specific length.
For sub-frame of uplink 7, feedback and sub-frame of uplink 2 similar, the sub-frame of uplink 7 of the subframe 9,0,3,1 in corresponding feedback window also will feed back (ACK, ACK, ACK, DTX), and wherein subframe 1 is special subframe.
