Description

For determining the method and apparatus of feedback and scheduling sequential

Technical field

Embodiments of the present invention relate to communication technical field, and relate more specifically to for determining the method and apparatus of feedback and scheduling sequential.

Background technology

In current time division duplex (TDD) Long Term Evolution (LTE) system, by providing multiple different up link (UL)-down link (DL) TDD configuration to support asymmetrical UL-DL to distribute.In existing LTE agreement, stipulated the frame structure of seven kinds of TDD configurations as shown in table 1:

Table 1

Wherein, D represents DL subframe, subframe that S represents special (S), and U represents UL subframe.Conventionally, S subframe also can be transmitted for DL, therefore, for the sake of simplicity, also " S " subframe is considered as to " D " subframe in this article.As shown in table 1, these configurations can provide 40% to 90% DL subframe.

Along with UL and DL business change, can periodic variation TDD configuration.At present, can transmit TDD configuration information via system information block 1 (SIB1), and the minimal modifications cycle of SIB1 is 640ms, this possibly cannot match with the transient change situation of business, thereby causes the level of resources utilization low.Thereby, proposed shorter dynamic TDD UL-DL configuration of cycle, thereby can more promptly business changed and be made a response.

Yet, when TDD configuration dynamically changes or reshuffles, if mixed automatic retransfer (HARQ) feedback is still determined feedback sequential according to the TDD configuration before changing, the subframe that is reportedly input into row response feedback for logarithm may fall into the subframe of base station (for example eNB) Planning Change link direction.In the situation that there is this conflict, according to existing agreement, cannot in corresponding subframe, feed back.This can cause very large block transmission delay, and particularly when the time scale of dynamic-configuration only has a few tens of milliseconds long, can cause very poor business throughput.

Existing LTE standard has been stipulated the sequential for the answering/no answering (ACK/NACK) of physics DL shared channel (PDSCH), shown in the table 2 of specific as follows.

Table 2

If the index value in table 2 in the corresponding unit lattice of each subframe represents with K, for the corresponding PDSCH subframe numbers of subframe feeding back, be n-K+10i, wherein i equals 0,1 or 2, when i equals 0 feedback for subframe in present frame, when i equals 1 feedback for subframe in former frame, when i equals 2 feedback for subframe in second frame above.For example, the index value K that subframe #3 is corresponding is 6 and 5, so the PDSCH subframe numbers of the feedback correspondence of subframe #3 is 3-6+10=7 and 3-5+10=8, the subframe #3 in present frame carries out response feedback to the subframe #7 in former frame and #8.For configuration 5, the index value K that subframe #2 is corresponding comprises 13, so corresponding PDSCH subframe numbers is 2-13+10+10=9, the subframe #2 in present frame carries out response feedback to the subframe #9 in second frame above.

Below with reference to Fig. 1 (a) and Fig. 1 (b), illustrating that TDD configuration dynamically changes or reshuffles causes ACK/NACK sequential to occur the situation of conflict.In the example as shown in Fig. 1 (a) and Fig. 1 (b), suppose, because DL business increases, TDD configuration to be become to configuration 2 from configuration 3.Fig. 1 (a) shows TDD and configures the ACK/NACK sequential for PDSCH in unaltered situation.As shown in Fig. 1 (a), when TDD configuration is while configuring 3, respectively at the UL subframe #3 of the second frame of two successive frames (frame) with the physical hybrid automatic repeat request indicator channel (PHICH) in UL subframe #4 is upper that the PDSCH subframe #7 of the first frame (being former frame) and #8 and PDSCH subframe #9 and #10 are carried out to response feedback, wherein the subframe corresponding relation of above-mentioned response feedback as mentioned above reference table 2 determine.When the TDD of the second frame configuration is after configuration 3 becomes configuration 2, as shown in Fig. 1 (b), subframe #3 and the #4 of the second frame become D from U.In this case, these two subframes are unrenewable in PDSCH being carried out to UL ACK/NACK feedback.

Equally, the ACK/NACK feedback for physics UL shared channel (PUSCH) also there will be similar feedback mapping conflict when TDD configuration dynamically changes.

In addition, the dynamic change of TDD configuration also can cause occurring conflict for the scheduling mapping of PUSCH.Table 3 below shows the sequential of the mandate of the UL for PUSCH of existing LTE standard regulation.

Table 3

Similarly, represent the index value in the corresponding unit lattice of each subframe in table 3 with K, the corresponding PUSCH subframe of subframe of now authorizing for UL is n+K-10.For example, for configuration 4, as shown in table 3, the index value that subframe #8 is corresponding is 4, so the UL in subframe #8 authorizes corresponding PUSCH subframe numbers, is 8+4-10=2; And index value corresponding to subframe #9 is 4, so the UL in subframe #9 authorizes corresponding PUSCH subframe numbers, be 9+4-10=3.That is to say, in the subframe #8 in present frame and subframe #9, transmission is authorized for the UL of the PUSCH subframe #2 in a rear frame and #3.

Fig. 2 (a) and Fig. 2 (b) show and from configuring 0, authorize the conflict of sequential while dynamically changing into configuration 4 for the UL of PUSCH when TDD configuration, wherein Fig. 2 (a) shows the sequential chart of authorizing for configuring 4 UL according to table 3, and Fig. 2 (b) shows the conflict that TDD configures the UL mandate sequential causing after configuration 4 becomes configuration 0 because up-downgoing business changes.As above, with reference to as described in table 3, the UL subframe #2 of the second frame (frame) and the UL of #3 for two continuous frames in Fig. 2 (a) authorize respectively in the DL subframe #8 of the first frame (being former frame) and the upper transmission of the physics DL control channel (PDCCH) in #9.Yet as shown in Fig. 2 (b), when the first frame becomes configuration 0 time from configuring 4, the subframe #8 of the first frame and #9 correspondingly become DL subframe from UL subframe, authorize in transmission UL so unrenewable.

In existing protocol, for above-mentioned feedback mapping conflict and scheduling mapping conflict, do not provide feasible solution.

Embodiment

Below in conjunction with accompanying drawing, embodiments of the present invention are explained in more detail and are illustrated.Should be understood that, drawings and the embodiments of the present invention are only for exemplary effect, not for limiting the scope of the invention.

Below in conjunction with accompanying drawing, in the mode of example, describe the embodiments of the present invention in detail.

Fig. 3 show according to an embodiment of the invention for determining that logarithm is reportedly input into the flow chart of method 300 of the sequential of row response feedback.

As shown in Figure 3, method 300 is after starting, at step S301, when the TDD configuration change of the rear frame of two continuous frames, selection configures with reference to TDD, for determining the sequential of the transfer of data at least one frame before TDD configuration change being carried out to response feedback, the subframe set that comprises this direction in previous TDD configuration with the set of the equidirectional subframe of transfer of data in the reference TDD wherein selecting configuration with change after TDD configuration in the subframe of all these directions in the intersection of subframe set of this direction.

For example, when DL transfer of data is carried out to response feedback, all DL subframes in the intersection of the DL subframe set in the TDD configuration after the set of the DL subframe in the reference TDD of selection configuration comprises DL subframe set in previous TDD configuration and changes.

Below, in conjunction with Fig. 4 (a) and 4 (b), the sequential of according to the embodiment of the present invention PDSCH being carried out ACK/NACK feedback is described, wherein Fig. 4 (a) show according to an embodiment of the invention PDSCH is carried out to the sequential of ACK/NACK feedback, Fig. 4 (b) show according to another implementation of the invention PDSCH is carried out to the sequential of ACK/NACK feedback.

As shown in Fig. 4 (a), the second frame (frame) that TDD is configured in two continuous frames becomes configuration 2 from configuring 3.In configuration 3, the set of DL subframe is { #0, #1, #5, #6, #7, #8, #9}, and in configuration 2 after change, the set of DL subframe is { #0, #1, #3, #4, #5, #6, #8, #9}.Therefore, the intersection of two DL subframes set is { #0, #1, #3, #4, #5, #6, #7, #8, #9}.According to existing seven kinds of TDD configuration, the DL subframe set in configuration 5 be #0, #1, #3, #4, #5, #6, #7, #8, #9}, so option and installment 5 is as the reference configuration for definite response feedback sequential.Because the set of configuration 5 DL subframe comprises the DL subframe of configuration 3 and configuration 2, thus correspondingly configure 3 and the set of the UL subframe of configuration 2 all comprise the UL subframe of configuration 5.Therefore it is feasible, according to the feedback sequential of configuration 5, in the frame that uses configuration 3 and configuration 2, PDSCH being carried out to ULACK/NACK feedback.

In this example, the set of DL subframe comprises that the TDD configuration of all DL subframes in intersection only has a configuration 5.And in some cases, the set that may have several TDD configurations all to meet DL subframe wherein comprises this criterion of all DL subframes in intersection.In this case, according to an embodiment of the invention, the set of selecting DL subframe is to comprise that the TDD of the minimal set of all DL subframes in this intersection configuration is as reference configuration.Table 4 below shows the configuration of the reference UL-DL for PDSCH HARQ according to this execution mode of the present invention.

Table 4

In the execution mode as shown in Fig. 4 (a), when the TDD configuration of the second frame is from configuring 3 while becoming configuration 2, according to the reference configuration 5 of selecting, determine the sequential of the PDSCH of the first frame being carried out to response feedback.Particularly, as shown in Fig. 4 (a), for the ACK/NACK of PDSCH subframe #0, #1, #5, #6, #7, #8 and the #9 of the first frame, be mapped to the subframe #2 of the second frame, wherein above-mentionedly for the subframe corresponding relation feeding back, can determine with reference to above-described table 2.

In the example of Fig. 4 (a), for PDSCH, carry out ACK/NACK feedback and carry out across two frames.Yet, in fact can there is situation about feeding back across three frames.For example, if previous TDD configuration is configuration 5, as previously mentioned, according to the feedback sequential shown in table 2 above, in the subframe #2 of the subframe #9 in the second frame (the namely former frame of the first frame in Fig. 4 (a)) before TDD configuration change in will the frame after TDD configuration change, feed back.In this case, according to the embodiment of the present invention, also according to configure to determine the sequential that the PDSCH subframe in the second frame before TDD configuration change is fed back with reference to TDD.

According to the criterion for selecting to configure with reference to TDD of the present invention, when DL transfer of data is carried out to response feedback, selected will be more than the DL number of sub frames in the TDD configuration before and after changing with reference to the DL number of sub frames in TDD configuration, accordingly, the UL number of sub frames in the reference TDD of selection configuration is relatively less.Therefore, likely can cause producing larger delay.For example,, if carry out ACK/NACK feedback according to 5 couples of PDSCH of reference configuration as shown in Fig. 4 (a), because only have a UL subframe in a frame of configuration 5, so can produce the feedback delay up to 13 subframes at most as mentioned above.

Fig. 4 (b) show according to another implementation of the invention PDSCH is carried out to the sequential of ACK/NACK feedback.In this embodiment, when the response feedback that will carry out in the former frame of two continuous frames that TDD configuration change occurs for the DL transfer of data of at least one frame before TDD configuration change is determined in configuration according to previous TDD, according to previous TDD configuration, determine the sequential of carrying out this response feedback in former frame; When the response feedback of carrying out in will the frame TDD configuration change after for the DL transfer of data of this at least one frame is determined in configuration according to previous TDD, according to the reference TDD selecting, configure and determine the sequential of carrying out this response feedback in the frame after TDD configuration change.

Particularly, as shown in Fig. 4 (b), if determine feedback sequential according to previous configuration 3, according to the feedback sequential of table 2, the subframe #4 that is mapped to the first frame for the feedback of the subframe #0 of the first frame is upper, and is all mapped on the second frame for subframe #1, #5, #6, #7, #8 and the #9 of the first frame.In this case, the feedback sequential of determining for the subframe #0 of the first frame according to configuration 3, and the feedback sequential of determining for subframe #1, #5, #6, #7, #8 and the #9 of the first frame according to the reference configuration 5 of selecting.That is to say, the PDSCH subframe #0 to the first frame on the subframe #4 of the first frame carries out ACK/NACK feedback, and PDSCH subframe #1, #5, #6, #7, #8 and the #9 to the first frame carries out ACK/NACK feedback on the subframe #2 of the second frame.In this way, can effectively reduce the delay of HARQ feedback.

Table 5 is below distortion of table 2, wherein shows concisely the exemplary criteria of determining whether HARQ feedback procedure will carry out across frame.

Table 5

If represent the index value in the corresponding unit lattice of each subframe in table 5 with K, the subframe numbers for feed back corresponding with subframe n is n+K-10i, and wherein i equals 0,1 or 2.If n+K > 9, shows to feed back and will carry out in the frame below, otherwise carry out at present frame.For example, for configuration 3 subframe #0, n+K=0+4=4, because 4 < 9, so carry out at present frame for the feedback of the subframe #0 of configuration 3.And for configuration 3 subframe #1, n+K=1+11=12, because 12 > 9, so the frame below carries out for the feedback of the subframe #1 of configuration 3.

Described above and according to the embodiment of the present invention PDSCH has been carried out the sequential of ACK/NACK feedback, the method according to this invention 300 is as shown in Figure 3 equally applicable to determine the situation of PUSCH being carried out to the sequential of ACK/NACK feedback.When to UL link data, response feedback is carried out in transmission, according to the embodiment of the present invention, all UL subframes in the intersection of the UL subframe set in the TDD configuration of the set of the UL subframe in the reference TDD of selection configuration after comprising UL subframe set in previous TDD configuration and changing.

Equally, when having several TDD configurations all to meet above-mentioned criterion, according to an embodiment of the invention, the set of selecting UL subframe is to comprise that the TDD of the minimal set of all DL subframes in this intersection configuration is as reference configuration, and the concrete configuration of the exemplary reference UL-DL for PDSCH HARQ as shown in Table 6 below.

Table 6

In embodiments of the present invention, according to the reference TDD configuration of selecting, determine the sequential of the UL transfer of data of at least one frame before TDD configuration change being carried out to response feedback.Can determine that feedback is replied sequential accordingly according to the sequential of the ACK/NACK for PUSCH of the existing LTE agreement regulation shown in table 7 below.

Table 7

Wherein, if represent the index value in the corresponding unit lattice of each subframe in table 6 with K, for the corresponding UL transfer of data of the subframe subframe of feeding back, be n+K-10i, wherein i equals 0 or 1.For example, for configuration 5, the index value that subframe #2 is corresponding is 6, so the DL subframe numbers feeding back for subframe #2 is 2+6=8.That is to say, in the subframe #8 for the response feedback of subframe #2 in present frame, carry out.

Similarly, determining when PUSCH is carried out to the sequential of ACK/NACK feedback, according to the embodiment of the present invention, when the response feedback that will carry out in the former frame of two continuous frames that TDD configuration change occurs for the UL transfer of data of at least one frame before TDD configuration change is determined in configuration according to previous TDD, according to previous TDD configuration, determine the sequential of carrying out this response feedback in former frame; When the response feedback of carrying out in will the frame TDD configuration change after for the UL transfer of data of this at least one frame is determined in configuration according to previous TDD, according to the reference TDD selecting, configure and determine the sequential of carrying out this response feedback in the frame after TDD configuration change.

Select detailed process and feature and similar above with reference to the feedback procedure for PDSCH of Fig. 4 (a) and 4 (b) description thereof for determining that the reference TDD of the feedback sequential of PUSCH configures and determine feedback sequential according to the TDD configuration of selecting, do not repeat them here.

In TDD LTE, be not that all DL subframes can be supported the PHICH for HARQ feedback.For example, configuration 5 comprises a UL subframe and 9 DL subframes, yet as described with reference to table 6, only has subframe #8 for UL subframe #2 is fed back above, and other 8 DL subframes all can not be for transferring ACK/NACK feedback.If directly according to the DL subframe that configures to be identified for feeding back with reference to TDD, likely cause definite DL subframe in fact there is no PHICH because reference configuration is different from actual disposition, thus cannot transferring ACK/NACK feedback.

In this case, according to an embodiment of the invention, when according to reference to TDD configuration, determine for carrying out the DL subframe of response feedback while not supporting the transmission of response feedback, if the response feedback of transmission is NACK, determine that in this subframe, transmitting UL authorizes, for indication NACK; If the response feedback of transmission is affirmative acknowledgement, determine that do not transmit UL authorizes, for example, for subscriber equipment (UE), according to having UL to authorize to determine, to media access control layer, not transmit affirmative acknowledgement from its oneself physical layer.Although according to existing LTE agreement, the sequential that sends UL mandate is consistent with the sequential of HARQ, that is to say, do not have the DL subframe of PHICH to authorize for transmitting UL, but because of having PDCCH in DL subframes all in TDDLTE, for authorizing to UE transmission DL, so can realize the transmission that UL authorizes with this PDCCH.

More than described according to an embodiment of the invention for determining that logarithm is reportedly input into the method for the sequential of row response feedback.The method can solve the problem that TDD configuration dynamically changes how to confirm HARQ feedback sequential while causing feedback mapping conflict occurs.

Above-mentioned feedback sequential determines that method can for example, locate to carry out at network element (eNB), then by eNB, by system message, sequential relevant information is offered to UE.Alternatively, this feedback sequential determines that method also can locate to carry out at terminal (as UE).For example, UE can select the configuration with reference to TDD according to the TDD configuration information obtaining from eNB, and correspondingly determines sequential.Can use identical sequential to determine criterion at eNB and UE place, so just not need extra signaling to transmit relevant information.

It should be noted that, it may occur to persons skilled in the art that embodiments of the present invention are not limited to the concrete regulation of above-mentioned LTE agreement, particularly concrete TDD configuration and the concrete feedback as shown in table 2 and table 7 as shown in table 1 shone upon sequential, but can be applied to exist in the situation of any TDD configuration and feedback mapping sequential.

Fig. 5 shows the flow chart for the method 500 of the sequential of the UL mandate of PUSCH for definite transmission according to an embodiment of the invention.

As shown in Figure 5, method 500, after starting, at step S501, when the TDD of two continuous frames configuration is different, is determined and in the former frame of two continuous frames, is transmitted the sequential that UL authorizes according to the TDD configuration of a rear frame of two continuous frames.

For example, as shown in Fig. 2 (a) and 2 (b), the TDD of the first frame of two continuous frames configuration becomes configuration 0 from configuring 4.According to the embodiment of the present invention, still according to configuration 4, determine and in the first frame, transmit the sequential that UL authorizes, concrete sequential mapping relations can be determined with reference to previously described table 3.In this embodiment, according to configuration 4 still by the UL authorization configuration of the subframe #2 for the second frame and #3 on the subframe #8 and #9 of the first frame.

Now, because the TDD of the first frame configuration becomes configuration 0 from configuring 4, its subframe #8 and #9 correspondingly become U from D, and UL subframe cannot be transmitted UL mandate, so this can cause producing mapping conflict.In this case, according to an embodiment of the invention, when being identified for transmitting subframe that UL authorizes and being UL subframe according to determined sequential, this subframe is not defined as to the subframe of authorizing for transmitting UL in former frame.This execution mode has solved the problem that dynamically changes how to confirm scheduling sequential while causing scheduling mapping conflict to occur as TDD, but because cannot transmitting UL, the subframe #8 of the first frame and #9 authorize, correspondingly the subframe #2 of the second frame and #3 also just cannot be for carrying out UL transfer of data, so can cause the UL wasting of resources.

In addition, as mentioned above, in TDD LTE, not all DL subframes are all configured for to transmission UL and authorize.In this case, if determine and transmit the sequential that UL authorizes in former frame according to the TDD configuration of a rear frame of two continuous frames, equally likely because to cause definite DL subframe be to be configured to be not used in the subframe that transmission UL authorizes for the TDD configuration of determining scheduling sequential is different with actual TDD configuration, thereby occur that scheduling mapping conflicts.

Fig. 6 (a) and 6 (b) show the example of the UL mandate sequential while there is this conflict.As shown in Fig. 6 (a), the TDD of the first frame of two continuous frames configuration is configuration 3, and the TDD of the second frame configuration is configuration 1.According to the embodiment of the present invention, according to configuration 1, determine and in the first frame, transmit the sequential that UL authorizes.As shown in Fig. 6 (a), according to the sequential of table 3, the UL that the subframe #6 of the first frame should transmit for the subframe #2 of the second frame authorizes, but according to the TDD configuration (configuring 3) of the first frame reality, subframe #6 has been configured to be not used in transmission UL and has authorized.

In this case, according to the embodiment of the present invention, in former frame, according to determined sequential, being identified for transmitting subframe that UL authorizes is while being configured to be not used in the DL subframe that transmission UL authorizes, and this subframe is not defined as to the subframe of authorizing for transmitting UL, as Fig. 6 (b).Equally, this execution mode also can cause the UL wasting of resources.

Below in conjunction with Fig. 7, the method for the sequential of the UL mandate of PUSCH for definite transmission is according to another implementation of the invention described.

As shown in Figure 7, method 700 is after starting, at step S701, when the TDD of two continuous frames configuration is different, selection configures with reference to TDD, for determining, in two continuous frames, transmit the sequential that UL authorizes, the set of the UL subframe in the reference TDD wherein selecting configuration comprise the TDD of the set of UL subframe and a rear frame of two continuous frames in the TDD configuration of former frame of two continuous frames configure in UL subframe in the intersection of UL subframe set.

With above-mentioned similar for the feedback sequential of PUSCH for determining, when having several TDD configurations all to meet above-mentioned criterion, according to an embodiment of the invention, the set of selecting UL subframe is to comprise that the TDD of the minimal set of all DL subframes in this intersection configuration is as reference configuration.The reference TDD configuration of authorizing according to the UL for PUSCH of this execution mode is selected with reference to table 6 too.

In one embodiment, according to the reference TDD configuration of selecting, determine that transmission is for the sequential of the UL mandate of UL transfer of data in two continuous frames.Fig. 8 (a) shows according to determine the example of scheduling sequential with reference to TDD configuration.As shown in Fig. 8 (a), when the TDD configuration of two continuous frames is respectively configuration 3 and configuration 1, the reference configuration of selecting is according to the embodiment of the present invention configuration 6, so determine and transmit the sequential that UL authorizes on the first frame and the second frame according to the scheduling sequential of configuration 6.

According to configure the sequential of determining that transmission UL authorizes with reference to TDD, equally likely because to cause definite DL subframe be the subframe that has been configured to be not used in transmission UL mandate with reference to TDD configuration is different with actual TDD configuration.According to an embodiment of the invention, when according to reference to TDD configuration, determine when transmitting DL subframe that UL authorizes and be configured to be not used in transmission UL and authorize, this subframe is defined as to the subframe of authorizing for transmitting UL.Equally, because have PDCCH in all DL subframe in TDD LTE, for authorizing to UE transmission DL, so can realize the transmission that UL authorizes with this PDCCH.Can effectively utilize UL subframe in this way, avoid the waste of UL resource.

Equally in order to reduce dispatch delay, according to an embodiment of the invention, when determining that according to the TDD configuration of a rear frame UL that will transmit for the UL subframe in a rear frame authorizes in a rear frame, according to the TDD configuration of a rear frame, determine the sequential of transmitting this UL mandate in a rear frame; And when determining that according to the TDD configuration of a rear frame UL that will transmit for the UL frame in a rear frame authorizes in former frame, according to determine the sequential of transmitting this UL mandate in former frame with reference to TDD configuration.Fig. 8 (b) shows the example of determining scheduling sequential according to this execution mode.

Selection with reference to TDD configuration and determine the scheduling process and character of sequential and the process of above-described definite feedback sequential similar, do not repeat them here.

Scheduling sequential for PUSCH according to the present invention determines that method equally both can carry out at network element place, also can carry out in end.That in specific implementation and method 300, describes is similar, does not repeat them here.Equally, it may occur to persons skilled in the art that for determining that the embodiment of scheduling sequential is not limited to the concrete scheduling mapping sequential shown in the concrete TDD configuration shown in table 1 and table 3, but can be applied to exist in the situation of any TDD configuration and feedback mapping sequential.
