Introduce the implementation procedure of downlink data transmission in detail below by embodiment.

Referring to Fig. 6, the method flow of asynchronous HARQ process is as follows in the present embodiment:

With the example that is transmitted as between UE and the base station.

Step 601: the base station sends the uplink scheduling signaling that comprises the HARQ progress information by PDCCH on descending sub frame n1.

Step 602:UE is according to sending data by PUSCH in the corresponding subframe of first sequential relationship on the HARQ process of HARQ progress information indication.

Step 603: the upstream data that UE sends is detected in the base station, if correct the reception then is left intact, otherwise continues step 604.

Step 604: the base station only sends the uplink scheduling signaling that comprises the HARQ progress information and retransmit indication information in described first kind subframe or described the 4th class subframe descending pilot frequency time slot.

Step 605:UE is according to first sequential relationship, data retransmission on corresponding available sub-frame of uplink.

For example, ascending HARQ sequential as shown in Figure 7.Uplink scheduling is initiated in subframe 0 (radio frame n) in the base station, and UE receives and calculates the transmission subframe according to the ascending HARQ sequential relationship and is: subframe 4 (radio frame n).UE sends upstream data in this subframe.The base station receives data in corresponding subframe, but receives mistake, and the base station selects a suitable subframe 0 (radio frame n+1) to initiate to be used for the PDCCH of uplink scheduling with the scheduling data retransmission according to the uplink-downlink configuration situation.UE receives PDCCH in corresponding subframe, and calculates the transmission subframe according to the ascending HARQ sequential relationship and be: subframe 8 (radio frame n+1).UE resends legacy data in this subframe.

Referring to Fig. 8, the method flow when synchronous HARQ mixes with asynchronous HARQ in the present embodiment is as follows:

With the example that is transmitted as between UE and the base station.

Step 801: the base station sends the uplink scheduling signaling that comprises the HARQ progress information by PDCCH on descending sub frame n1.

Step 802:UE is according to sending data by PUSCH in the corresponding subframe of first sequential relationship on the HARQ process of HARQ progress information indication.

Step 803: the upstream data that UE sends is detected in the base station, and judge that according to first sequential relationship whether the subframe that is used to transmit data on the HARQ process of HARQ progress information indication is the subframe that is used to transmit data of the synchronous HARQ process correspondence that disposes, if correctly receive and be not the subframe that is used to transmit data of synchronous HARQ process correspondence, then be left intact, if correctly receive and be the subframe that is used to transmit data of synchronous HARQ process correspondence, then continue step 804, if mistake receives and is not the subframe that is used to transmit data of synchronous HARQ process correspondence, then continue step 806, if mistake receives and is the subframe that is used to transmit data of synchronous HARQ process correspondence, then continue step 808.The base station can judge whether the subframe that is used to transmit data of asynchronous HARQ process correspondence for configuration in this step, judges whether to be the subframe that is used to transmit data of synchronous HARQ process correspondence of configuration with replacement.

Step 804: the base station sends ACK on subframe n2+k2.N2+k2 is determined by second sequential relationship shown in the table 3.N2 is the subframe of transmission data.

Step 805:UE receives ACK on the relevant position.UE judges that according to first sequential relationship whether the subframe that is used to transmit data on the HARQ process of HARQ progress information indication is the subframe that is used to transmit data of the synchronous HARQ process correspondence that disposes in advance, if the subframe that is used to transmit data of synchronous HARQ process correspondence, then continue step 805 or step 809, if not, then wait for and receive the uplink scheduling signaling, if receive, then continue step 807.

Step 806: the base station only sends the uplink scheduling signaling that comprises the HARQ progress information and retransmit indication information in described first kind subframe or described the 4th class subframe descending pilot frequency time slot.

Step 807:UE is according to first sequential relationship, data retransmission on corresponding available sub-frame of uplink.

Step 808: the base station sends NACK on subframe n2+k2.N2+k2 is determined by second sequential relationship shown in the table 3.

Step 809:UE is according to first sequential relationship, data retransmission on the nearest available sub-frame of uplink of distance subframe n2+k2.

For example, ascending HARQ sequential as shown in Figure 9.Uplink scheduling is initiated in subframe 1 (radio frame n) in the base station, and the transfer of data subframe of subframe 1 correspondence is a subframe 7, and subframe 7 corresponding synchronous HARQs.UE receives and calculates the transmission subframe according to the ascending HARQ sequential relationship: subframe 7 (radio frame n).UE sends upstream data in this subframe.The base station receives data in corresponding subframe, but receives mistake, then at subframe 1 (radio frame n+1) feedback NACK.UE receives the PHICH that has NACK in corresponding subframe, and retransmits in subframe 7 (radio frame n+1).Adopt different frequency domain resource and/or modulation coding mode if the base station needs UE to retransmit, then initiate to comprise that the PDCCH of uplink scheduling signaling is to carry out retransfer scheduling in subframe 1 (radio frame n+1).UE receives PDCCH in corresponding subframe, and retransmits in subframe 7 (radio frame n+1).If initiate to retransmit by UL grant (uplink scheduling signaling), be not limited to subframe 1 (radio frame n+1), can be the subframe 1 of follow-up any radio frames.

Sequential relationship shown in direct application drawing 5 or table 2 or the table 3, corresponding subframe may be configured to disabled subframe, then needs the sequential relationship shown in secondary application drawing 5 or table 2 or the table 3 to determine available subframe.Preferable mode is that the configuration of frame structure is just considered in the base station before scheduling, adjust the subframe at dispatch place, so that the sequential relationship shown in application drawing 5 of UE or table 2 or the table 3 can be determined available subframe.That is, receiving terminal sends before the uplink scheduling signaling, according to first sequential relationship of dispatch and transfer of data, judges whether the corresponding described second class subframe or described the 3rd class subframe of first sequential relationship indication be available; If then receiving terminal sends the uplink scheduling signaling on the corresponding subframe of first sequential relationship indication; Otherwise receiving terminal is searched next corresponding described second class subframe or described the 3rd class subframe according to first sequential relationship, and judges whether this subframe is available.

For the UE that does not support dynamic TDD uplink-downlink configuration, present embodiment can provide compatible scheme.The control information that the base station sends also comprises the uplink-downlink configuration type information.The base station is according to the sequential relationship of uplink-downlink configuration type correspondence and the dynamic synchronous HARQ sequential relationship of subframe systemic presupposition, with uplink data scheduling in two kinds of sequential relationships on the identical sequential.The configuration 1 of stipulating in sequential relationship shown in Figure 5 and the agreement at present in the present embodiment has to small part sequential compatibility.Referring to the HARQ sequential relationship of configuration shown in Figure 10 1, wherein the sequential relationship of square frame delineation is compatible sequential relationship.As shown in Figure 10, the sequential relationship in the present embodiment is compatible on sequential 5 and 6 with configuration 1.The base station is according to user's business demand, and uplink service can be dispatched on sequential 5 and 6.
