In this embodiment, MTC terminal can derive upstream data maximum repetition transmission times and the maximum repetition transmission times of downlink data of often kind of TDD time slot configuration support according to ad hoc fashion.MTC terminal also can to obtain by predetermined manner the upstream data maximum repetition transmission times and the maximum repetition transmission times of downlink data that often kind of TDD time slot configuration can support to base station.Wherein, the maximum repetition transmission times of upstream data can refer to that upstream data allows the maximum times repeating to send, and the maximum repetition transmission times of downlink data can refer to that downlink data allows the maximum times repeating to send.Uplink/downlink transmission under often kind of TDD time slot configuration can have different repetition transmission times, but the maximum repetition transmission times of uplink/downlink transmission is unique.The maximum repetition transmission times of upstream data that different TDD time slot configuration can be supported can be different, also can be identical; The maximum repetition transmission times of downlink data that different TDD time slot configuration can be supported can be different, also can be identical; The upstream data maximum repetition transmission times of same TDD time slot configuration and the maximum repetition transmission times of downlink data can be different, also can be identical, and the embodiment of the present invention is not construed as limiting.For example, TDD time slot configuration 1 time transmission 10 subframes " DSUUDDSUUD ", wherein, D represents descending sub frame, and U represents sub-frame of uplink, and S represents special subframe, can see special subframe S as descending sub frame here.In above-mentioned 10 subframes, descending maximum continuous print number of sub frames is 3, up maximum continuous print number of sub frames is 2, therefore the known maximum repetition transmission times of downlink data can supported for 1 time in TDD time slot configuration is 3, and the maximum repetition transmission times of the upstream data that can support is 2.
In this embodiment, after the upstream data maximum repetition transmission times getting the support of various TDD time slot configuration and the maximum repetition transmission times of downlink data, for each TDD time slot configuration, can determine according to the upstream data maximum repetition transmission times of this TDD time slot configuration support the maximum HARQ process number that uplink takies under this TDD time slot configuration, thus can obtain or upgrade the first corresponding relation of the maximum HARQ process number that different TDD time slot configuration and uplink take.Wherein, the maximum HARQ process number that uplink takies can refer to when uplink at most can the HARQ process number of parallel running.The maximum HARQ process number that the uplink that different TDD time slot configuration is corresponding in the first corresponding relation takies can be different, also can be identical.Wherein, the first corresponding relation between the maximum HARQ process number that takies of different TDD time slot configuration and uplink is as shown in table 1 below.
Table 1
In this embodiment, for each TDD time slot configuration, can determine according to the downlink data maximum repetition transmission times of this TDD time slot configuration support the maximum HARQ process number that downlink transfer takies under this TDD time slot configuration, thus can obtain or upgrade the second corresponding relation of the maximum HARQ process number that TDD time slot configuration and downlink transfer take.Wherein, the maximum HARQ process number that downlink transfer takies can refer to when downlink transfer at most can the HARQ process number of parallel running.The maximum HARQ process number that the downlink transfer that different TDD time slot configuration is corresponding in the second corresponding relation takies can be different, also can be identical, wherein, the second corresponding relation between the maximum HARQ process number that takies of different TDD time slot configuration and downlink transfer is as shown in table 2 below.
Table 2
As can be seen from Table 1, TDD time slot configuration is 0 ~ 6 totally seven kinds, the maximum HARQ process number that uplink corresponding under different TDD time slot configuration takies is 2, namely under each TDD time slot configuration, parallel running 2 HARQ processes can carry out uplink at most.
As can be seen from Table 2, TDD time slot configuration is 0 ~ 6 totally seven kinds, and the maximum HARQ process number that downlink transfer corresponding to different TDD time slot configuration takies has identical, also has difference.The maximum HARQ process number that the downlink transfer of TDD time slot configuration 0 ~ 4 correspondence takies is 3, namely TDD time slot configuration 0 ~ 4 time, parallel running 3 HARQ processes can carry out downlink transfer at most.The maximum HARQ process number that the downlink transfer of TDD time slot configuration 5 and 6 correspondence takies is 2, namely TDD time slot configuration 5 and 6 times, parallel running 2 HARQ processes can carry out downlink transfer at most.
In this embodiment, the first corresponding relation obtained and the second corresponding relation can be stored in MTC terminal this locality by MTC terminal, and in addition, the first corresponding relation and the second corresponding relation also can be sent to base station and store by MTC terminal.
For TDD time slot configuration 1 in table 1 and table 2, its uplink maximum HARQ process number is 2, and downlink transfer maximum HARQ process number is 3.MTC system specifies, PDSCH transmission is at least one subframe after corresponding down control channel transmission.10 subframes " DSUUDDSUUD " of TDD time slot configuration 1 time transmission, being 3 by the maximum repetition transmission times of the known downlink data of descending maximum continuous print number of sub frames, is 2 by the maximum repetition transmission times of the known upstream data of up maximum continuous print number of sub frames.When carrying out downlink transfer with the maximum repetition transmission times of downlink data, subframe 0/1 pair of subframe 4/5/6 is dispatched, consider that downlink data feedback needs first sub-frame of uplink transmission after at least 4ms, therefore the feedback of subframe 4/5/6 occurs in the subframe 2 of next frame the earliest.And according to the regulation of LTE system, before a HARQ process release, other subframes can not be distributed to transmit, therefore need to subframe 0/1,4/5/6,9/0/1 (next frame) is each distributes a HARQ process respectively, thus show that the maximum HARQ process number taken in TDD time slot configuration 1 time downlink transfer is 3.In like manner, sub-frame of uplink 2/3,7/8 needs each distribution HARQ process, is therefore 2 at the maximum HARQ process number that the 1 time uplink of TDD time slot configuration takies.
As the optional execution mode of one, step 22) embodiment of the MTC terminal upstream data maximum repetition transmission times and the maximum repetition transmission times of downlink data that obtain the support of TDD time slot configuration from base station can comprise:
MTC terminal obtains maximum repetition transmission times physically row shared channel PUSCH of upstream data that TDD time slot configuration supports and the maximum repetition transmission times of downlink data in Physical Downlink Shared Channel PDSCH from base station.
Wherein, the transmission of upstream data is carried out in PUSCH channel, and the transmission of downlink data is carried out in PDSCH channel.
S203, MTC terminal are to base station uplink transmission data block, and wherein, the HARQ process number shared by uplink transmission data block is not more than the maximum HARQ process number that uplink under current TDD time slot configuration takies.
S204, MTC terminal receive the data block of base station down transmission, and wherein, the HARQ process number shared by the data block of downlink transfer is not more than the maximum HARQ process number that downlink transfer under current TDD time slot configuration takies.
As the optional execution mode of one, the method described by Fig. 2 can also comprise the following steps:
25) after MTC terminal receives the target-subframe of base station down transmission, the N number of subframe after target-subframe transmission transmits HARQ feedback information for target-subframe, wherein, N be not less than 4 positive integer, N number of subframe is sub-frame of uplink.
In this embodiment, owing to being limited to system processing delay and propagation delay time, it is 4ms that downlink data feeds back minimum time delay, therefore, after MTC terminal receives the target-subframe of base station down transmission, N number of subframe of MTC terminal after the transmission of this target-subframe is transmitted the HARQ feedback information for this target-subframe.HARQ feedback information can comprise ACK (Acknowledgement determines) feedback or NACK negative feedback.When feeding back for ACK, can show that MTC terminal receives and resolves target-subframe success, now base station can the next subframe of downlink transfer; When feeding back for NACK, can show that MTC terminal is resolved unsuccessfully to target-subframe, now base station can repeat to send this target-subframe, and the number of times repeating to send can not exceed the maximum repetition transmission times of downlink data that current TDD time slot configuration is supported.MTC terminal sends after feedback information to base station, then can the HARQ process of release busy.
In this embodiment, the feedback information of the target-subframe of downlink transfer is transmitted by sub-frame of uplink, and therefore N number of subframe is sub-frame of uplink.Now N can be 4,5,6 ...
In this embodiment, because downlink data transmission is carried out in PDSCH channel, the feedback for downlink data is carried out in PUCCH (PhysicalUplinkControlChannel, Physical Uplink Control Channel) channel; The transmission of upstream data is carried out in PUCCH channel, and the feedback for upstream data is carried out in PDCCH (PhysicalDownlinkControlChannel, Physical Downlink Control Channel) channel.After MTC terminal receives the target-subframe of base station downlink transfer in PDSCH channel, PUCCH channel corresponding to N number of subframe after target-subframe transmission is for the HARQ feedback information of target-subframe.
As the optional execution mode of one, N can be 4, and namely N is numerical value minimum in the scope of permission, and the 4th sub-frame of uplink after this downlink transfer sends feedback information, HARQ sequential relationship is redesigned, thus makes the time delay of HARQ information feed back minimum.
