Step 601: the base station sends the uplink scheduling signaling by PDCCH on descending sub frame n1.
Step 602:UE sends data by PUSCH according to first sequential relationship on the nearest sub-frame of uplink of distance subframe n1.
Step 603: the upstream data that UE sends is detected in the base station, if correct the reception continued step 604, otherwise continues step 606.
Step 604: the base station sends ACK on subframe n2+k2.N2+k2 is determined by second sequential relationship shown in the table 3.
Step 605:UE receives ACK on the relevant position.
Step 606: the base station sends NACK on subframe n2+k2.
Step 607:UE receives NACK on the relevant position.
Step 608:UE is according to first sequential relationship, data retransmission on the nearest available sub-frame of uplink of distance subframe n2+k2.
For example, at sequential relationship shown in Figure 4, a concrete example is referring to ascending HARQ sequential shown in Figure 7.Uplink scheduling is initiated in subframe 0 in the base station, UE receives and calculates available transmission subframe according to the ascending HARQ sequential relationship: subframe 4 (radio frame n), subframe 7 (radio frame n+1), subframe 8 (radio frame n+2), subframe 9 (radio frame n+3) ....Wherein, subframe 4 (radio frame n) is a descending sub frame by flexible configuration, can not be used for uplink, and then subframe 7 (radio frame n+1) is the sub-frame of uplink nearest apart from subframe 0, and UE selects this subframe to send upstream data.Because subframe be static or semi-static distribution in the prior art, HARQ sequential and sub-frame configuration binding, it is necessarily available therefore to pass through the definite subframe of HARQ sequential relationship, does not have the process of judging that corresponding subframe is whether available.And therefore present embodiment need judge whether corresponding subframe is available at the HARQ sequential relationship of the subframe design of dynamic assignment when using this sequential relationship.Afterwards, the base station receives data in corresponding subframe, but receives mistake, then feed back in subframe 1 (radio frame n+2), send NACK by PHICH,, perhaps send NACK and pass through PDCCH feedback scheduling signaling by PHICH simultaneously perhaps by PDCCH feedback scheduling signaling.UE receives PHICH or PDCCH or PHICH and PDCCH in corresponding subframe, and calculates according to the ascending HARQ sequential relationship and to retransmit subframe and be: subframe 8 (radio frame n+2), subframe 9 (radio frame n+3) ....Wherein, subframe 8 (radio frame n+2) is a descending sub frame by flexible configuration, can not be used for uplink, and then subframe 9 (radio frame n+3) is apart from the nearest sub-frame of uplink of subframe 1 (radio frame n+2), UE selects this subframe to resend legacy data, i.e. data retransmission.The base station receives data in corresponding subframe.
And for example, at sequential relationship shown in Figure 5, a concrete example is referring to ascending HARQ sequential shown in Figure 8.Uplink scheduling is initiated in subframe 0 in the base station, UE receives and calculates available transmission subframe according to the ascending HARQ sequential relationship: subframe 4 (radio frame n), subframe 8 (radio frame n+1), subframe 9 (radio frame n+2), subframe 3 (radio frame n+4) ....Wherein, subframe 4 (radio framen) is a descending sub frame by flexible configuration, can not be used for uplink, and then subframe 8 (radio frame n+1) is the sub-frame of uplink of and flexible configuration nearest apart from subframe 0, and UE selects this subframe to send upstream data.Because subframe be static or semi-static distribution in the prior art, HARQ sequential and sub-frame configuration binding, it is necessarily available therefore to pass through the definite subframe of HARQ sequential relationship, does not have the process of judging that corresponding subframe is whether available.And therefore present embodiment need judge whether corresponding subframe is available at the HARQ sequential relationship of the subframe design of dynamic assignment when using this sequential relationship.Afterwards, the base station receives data in corresponding subframe, but receives mistake, then feed back in subframe 5 (radio frame n+2), send NACK by PHICH,, perhaps send NACK and pass through PDCCH feedback scheduling signaling by PHICH simultaneously perhaps by PDCCH feedback scheduling signaling.UE receives PHICH or PDCCH or PHICH and PDCCH in corresponding subframe, and calculates according to the ascending HARQ sequential relationship and to retransmit subframe and be: subframe 9 (radio frame n+2), subframe 3 (radio frame n+4) ....Wherein, subframe 9 (radio frame n+2) is a descending sub frame by flexible configuration, can not be used for uplink, then subframe 3 (radio frame n+4) is the sub-frame of uplink of and flexible configuration nearest apart from subframe 5 (radio frame n+2), UE selects this subframe to resend legacy data, i.e. data retransmission.The base station receives data in corresponding subframe.
From embodiment shown in Figure 6 as can be seen, sequential relationship shown in direct application drawing 4 (or Fig. 5) or table 1 (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 4 (or Fig. 5) or table 1 (or table 2) or the table 3 to determine available subframe.Preferable mode is, 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 an application drawing 4 of UE (or Fig. 5) or table 1 (or table 2) or the table 3, can determine available subframe, referring to the following examples.
Referring to Fig. 9, the method flow when transmitting uplink data is determined by table 1 (or table 2) in the present embodiment is as follows:
With the example that is transmitted as between UE and the base station.
Step 901: the base station is determined fixedly sending the uplink scheduling signaling by PDCCH on the descending sub frame n1 (as certain radio frames t).
Step 902: corresponding subframe is determined according to the sequential relationship shown in the table 1 (or table 2) in the base station, and judge whether this corresponding subframe is available, judge promptly whether corresponding described second class subframe or described the 3rd class subframe be available, if, then continue step 903, otherwise continue step 904.
Step 903: the base station sends the uplink scheduling signaling on the fixedly descending sub frame of determining.Continue step 905.
Step 904: next corresponding subframe is searched according to first sequential relationship in the base station.Continue step 902.
Step 905:UE is according to the 3rd sequential relationship (perhaps first sequential relationship and second sequential relationship), sends data by PUSCH on nearest available second class subframe of distance subframe n or the 3rd class subframe.Subframe n in this step is the subframe of final transmission uplink scheduling signaling, and this subframe may be the n1 in the step 901, also may be other subframe after searching through step 904.
Step 906: the upstream data that UE sends is detected in the base station, if correct the reception continued step 907, otherwise continues step 907 and step 908.
Step 907: the base station sends ACK on subframe n2+k2.N2+k2 is determined by second sequential relationship shown in the table 2.Subframe n2 is the subframe of transmit ascending data.
Step 908: the base station is by PDCCH feeding back uplink dispatch.This step can realize in same subframe with ACK, also can fixedly realize in the descending sub frame at other.This moment, the base station can judge according to the subframe of transmission PDCCH and by table 1 (or table 2) whether corresponding subframe is available earlier, if it is available, then on current definite subframe, transmit the uplink scheduling signaling, otherwise next first kind subframe or described the 4th class subframe descending pilot frequency time slot at the indication of first sequential relationship are judged, can use until corresponding subframe, then transmission uplink scheduling signaling on corresponding subframe.
Step 909:UE receives ACK on the relevant position.This moment, UE did not do other processing.
Step 910:UE receives the uplink scheduling signaling by PDCCH on the relevant position, and determines corresponding subframe according to the sequential relationship shown in the table 1 (or table 2).
Step 911:UE is data retransmission on the subframe of determining.
For example, at sequential relationship shown in Figure 4, a concrete example is referring to ascending HARQ sequential shown in Figure 10.The base station has upstream data to need scheduling in subframe 0 (radio frame n), but because the directly corresponding transmission subframe 4 (radio frame n) of subframe 0 is configured to descendingly, can't send upstream data, and scheduling can only lag behind.A nearest available scheduling subframe 0 (radio frame n+1) is found in the base station, sends UL grant (uplink scheduling signaling) dispatching uplink data.UE receives and calculates the transmission subframe according to the ascending HARQ sequential relationship in corresponding subframe: subframe 7 (radio frame n+1), UE selects this subframe to send upstream data.The base station receives data in corresponding subframe, but receives mistake, then feeds back in subframe 1 (radio frame n+2).Because it is descending that the directly corresponding transmission subframe 8 (radio frame n+2) of subframe 1 (radio frame n+2) is configured to, and can't send upstream data.So the base station sends ACK, and retransmit by the PDCCH scheduling afterwards.UE receives PHICH in corresponding subframe, is found to be ACK, does not do any processing.Available scheduling subframe 5 (radio frame n+3) is recently found in the base station in subsequent subframe, and sends UL grant triggering UE re-transmission in this subframe.UE detects PDCCH and calculates the re-transmission subframe according to the ascending HARQ sequential relationship in the relevant position: subframe 9 (radio frame n+3), UE selects this subframe to resend legacy data.The base station receives data in corresponding subframe.
And for example, at sequential relationship shown in Figure 5, a concrete example is referring to ascending HARQ sequential shown in Figure 11.The base station has upstream data to need scheduling in subframe 0 (radio frame n), but because the directly corresponding transmission subframe 4 (radio frame n) of subframe 0 is configured to descendingly, can't send upstream data, and scheduling can only lag behind.A nearest available scheduling subframe 0 (radio frame n+1) is found in the base station, through judging, determine that corresponding subframe is sub-frame of uplink 8 available and flexible configuration (radio frame n+1), therefore send PDCCH with the dispatching uplink data in subframe 0 (radio frame n+1).UE receives and calculates the transmission subframe according to the ascending HARQ sequential relationship in corresponding subframe: subframe 8 (radio frame n+1), UE selects this subframe to send upstream data.The base station receives data in corresponding subframe, but receives mistake, then feeds back in subframe 5 (radio frame n+2).Because it is descending that the directly corresponding transmission subframe 9 (radio frame n+2) of subframe 5 (radio frame n+2) is configured to, and can't send upstream data.So the base station sends ACK, and retransmit by the PDCCH scheduling afterwards.UE receives PHICH in corresponding subframe, is found to be ACK, does not do any processing.Available scheduling subframe 5 (radio frame n+3) is recently found in the base station in subsequent subframe, and sends PDCCH triggering UE re-transmission in this subframe.UE detects PDCCH and calculates the re-transmission subframe according to the ascending HARQ sequential relationship in the relevant position: subframe 3 (radio frame n+4), UE selects this subframe to resend legacy data.The base station receives data in corresponding subframe.
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 sequential relationship of subframe systemic presupposition, with uplink data scheduling in two kinds of sequential relationships on the identical sequential.Configuration 0, configuration 1, the configuration 3 of stipulating in sequential relationship shown in Figure 4 and the agreement at present in the present embodiment and dispose 6 and have to small part sequential compatibility.Referring to configuration 0, configuration 1, the configuration 3 of Figure 12-shown in Figure 15 with dispose 6 HARQ sequential relationship, wherein the sequential relationship of square frame delineation be the sequential relationship of compatibility.As shown in Figure 12, the sequential relationship in the present embodiment is compatible fully with configuration 0.As shown in Figure 13, the sequential relationship in the present embodiment is compatible on sequential 2 with configuration 1.As shown in Figure 14, the sequential relationship in the present embodiment is compatible on sequential 1 with configuration 3.As shown in Figure 15, the sequential relationship in the present embodiment is compatible on sequential 2,3 with configuration 6.Therefore, transmitting terminal can also carry progress information (as process number) etc. in dispatch.
Concrete, if the base station is employing TDD UL/DL configuration0 to the Rel-8/9/10UE notice, uplink service can be dispatched on the subframe 2,3,4,7,8 or 9 of all processes.
If for adopting TDD UL/DL configuration1, uplink service can be dispatched on the subframe 7 of all processes to the Rel-8/9/10UE notice in the base station.
