Fig. 3 is the method flow schematic diagram of another embodiment of the present invention, the present embodiment for PUCCH feedback resource for base station configures to the special feedback resources of UE.See Fig. 3, the present embodiment comprises:
Step 31:eNB issues RRC information to UE, is included as the SPS information of UE configuration in this RRC information.
Wherein, this SPS information comprises: SPS cycle and PUCCH feedback resource.In the present embodiment, be the PUCCH feedback resource of this UE configure dedicated, that is, in group, each UE has the PUCCH feedback resource of oneself.The UE method identified whether as oneself being configured with special PUCCH feedback resource includes but not limited to several as follows: whether eNB indicates this PUCCH feedback resource to be that UE is special in RRC information, or increase new parameter of distributing (namely sharing in group) PUCCH feedback resource of non-dedicated, if use the PUCCH resource of existing parametric distribution, it is then the private resource of UE, if by the PUCCH resource of new parametric distribution, be not then the private resource of UE; Or when the PUCCH quantity that eNB indicates in RRC information is 1, UE thinks that described PUCCH feedback resource is that UE is special, when quantity is greater than 1, not thinks it is special.
In addition, also can be that UE configures SPS group scheduling mark (as Group-SPS-RNTI) by RRC information, or, SPS group scheduling mark also can be the group mark that beep-page message is corresponding, owing to carrying group mark in beep-page message, therefore can directly this group mark be identified as SPS group scheduling; Also can be adopt the mode of static configuration, be pre-configured in UE side.UE can adopt SPS group scheduling to identify solution and cover out self control signal corresponding, so that the control signal covered according to solution carries out data receiver.
Step 32:eNB sends through adding the control signal covered on PDCCH, comprises SPS order in this control signal, and wherein, this SPS order is used for carrying out SPS scheduling to the UE in the grouping of described UE place.In addition, eNB is at Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) upper transmission MAC PDU, the packet of at least one UE of this UE place grouping is comprised in this MAC PDU, this packet can be one or more MAC service data unit (MACService Data Unit, and/or one or more MAC Control Element (MAC ControlElements, CE) SDU).
Wherein, SPS order comprises: SPS activates/revise order and SPS release command.The one or more territories in the control signal of transmission on existing PDCCH can be adopted to show, and this SPS order is that SPS activates/amendment order, or SPS release command.Such as, work as NDI=0, represent that SPS activates/amendment order, work as NDI=1, represent SPS release command.
In the embodiment of the present invention, can realize the SPS scheduling based on group, when namely needing the number of the UE dispatched more than one, the control signal that can be transmitted by PDCCH is activated simultaneously/revises or discharges the UE in this group.
Step 33:UE monitors PDCCH, adopts SPS group scheduling mark solution to cover the control signal transmitted on PDCCH, and wherein, the UE in same grouping shares a SPS group scheduling mark.Wherein, the SPS group scheduling mark of UE side can be that eNB adopts RRC information to configure to UE, also can be the group mark that beep-page message is corresponding, also can be pre-configured in UE.
Control signal after step 34:UE covers according to described solution, receives the MAC PDU on PDSCH, and described MAC PDU comprises the packet of at least one UE in the grouping of described UE place.
Wherein, solution cover after control signal in comprise physical channel resources corresponding to UE, so that UE can receive data to the PDSCH of correspondence.
Particularly, be configured with the UE of SPS information after getting SPS order, corresponding SPS can be carried out and receive operation.Such as, if SPS order is for activating/amendment order, then UE is after receiving SPS activation/amendment order, then from receive SPS activate/amendment order time point or SPS activate/amendment order in instruction time point, with the SPS cycle of above-mentioned configuration for the cycle, in the PDSCH resource that periodic trial indicates in SPS order with the mode of SPS order instruction (as the modulation coding mode that uses, the size etc. of the data block transmitted) carry out data receiver, and use the PUCCH resource of above-mentioned configuration to feed back according to data receiver situation.If SPS order is SPS release command, then UE is follow-up no longer receives.
Step 35:UE, according to described SPS order and the reception condition to described control signal and described MAC PDU, the feedback resources indicated by the SPS information obtained in advance sends feedback information or does not feed back.
Such as, when SPS order activates/revises order for SPS, if UE successfully solution covers the control signal of transmission on PDCCH, and the MAC PDU of PDSCH transmission of successfully decoding, no matter then whether have oneself packet in the decoded MAC PDU of success, then by the PUCCH of above-mentioned configuration to eNB feeding back ACK information; If UE successfully solution covers the control signal that PDCCH carries, but the MAC PDU that unsuccessful decoding PDSCH carries, then feed back nack message by the PUCCH of above-mentioned configuration to eNB; If the unsuccessful solution of UE covers the control signal that PDCCH carries, then do not feed back.
Again such as, if when SPS order is SPS release command, then feed back according to the reception condition of control signal, such as, when UE successfully receives this control signal, namely UE successfully solution cover out control signal, then feeding back ACK information, otherwise, do not feed back.
Step 36:eNB carries out respective handling according to the feedback of UE.
Such as, if scheduled the data of described UE: receive ACK, think that control signal and data are all successfully received by UE; If receive NACK, then think that UE receives only PDCCH and do not solve PDSCH; If do not received whatever, then think that UE does not receive PDCCH.After receiving ACK or NACK, think that UE receives PDCCH, the follow-up data that can use this UE of group SPS resource transmission; If do not received whatever, then think that UE does not receive PDCCH, the data of this UE of SPS transmitted over resources of the follow-up SPS order notice can not transmitted on this PDCCH.Optionally, in order to improve reliability, when certain or some UE do not feed back, the SPS activation command that eNB can resend on PDCCH activates, and for the UE receiving this SPS activation command, this SPS activation command can be understood as SPS amendment order.
Wherein, after SPS successful activation or amendment, UE activates/revises at this SPS the MAC PDU and the data having oneself in this MAC PDU that order the PDSCH transmitted over resources of instruction follow-up successfully receiving, the PUCCH resource feeding back ACK preset, if successfully receive MAC PDU but there is no oneself data, can not feed back or feed back NACK or feeding back ACK, if UE does not successfully receive MAC PDU, then can not feed back, or feedback NACK; Simultaneously, if UE does not successfully solve MAC PDU, the control signal that possible SPS group scheduling mark adds the Schedule retransmission covered can be monitored, carry out SPS re-transmission, and respective feedback is carried out in pre-configured PUCCH resource or at the relative position of the CCE (Control Channel Element, control channel unit) shared by control signal.Accordingly, in eNB side, if eNB does not have the data of execution cost UE, then eNB can ignore the feedback of this UE.
Wherein, scheduled the data of certain UE as eNB and receive the NACK of UE feedback, then can carry out Schedule retransmission, when eNB retransmits the data of certain or some UE, can continue to use the mode of group scheduling to dispatch the data of UE, or the mode of notice specific schedule retransmits the data of UE.
If UE has exited this group, or SPS business corresponding to UE is released, then this UE does not need monitoring group SPS to dispatch again, can be eNB by signaling explicit notification to UE, also can be that UE judges according to configuration.
It is noted that because the business of different UEs is different, the SPS cycle is also different, but is meeting under certain condition, group SPS scheduling can realize the SPS group scheduling of multiple UE in different SPS cycle.Such as, some UE is the SPS cycle of 20ms, some UE is the SPS cycle of 40ms, when use group SPS dispatches, use the UE in the SPS cycle of 20ms only to need to carry out data receiver in the moment of activationary time point+20ms integral multiple, and use the UE in the SPS cycle of 40ms only to need to carry out data receiver in the moment of activationary time point+40ms integral multiple.
Under normal circumstances, same UE group SPS scheduling and special SPS scheduling (add with SPS-RNTI and cover) can not activate simultaneously.But the priority ratio group SPS optimizing scheduling level of special SPS dispatch is high, that is:
When UE is using special SPS scheduling to carry out data receiver, UE is the signaling of monitoring group SPS scheduling and data no longer;
When UE use group SPS dispatches, special SPS release command can be used to modify or discharge; When for amendment time, eNB and UE carries out SPS transmission according to special SPS order, follow-up same as the prior art, UE also no longer monitoring group SPS dispatch signaling and data; When for release, the data before UE also no longer receives corresponding to use group SPS order, unless UE listens to group SPS activation command again.
Owing to using the usual data volume of business of SPS scheduling mode fewer, so use the UE of SPS scheduling to form one group multiple needs, use group scheduling, on the basis of reducing PDCCH expense, the resource utilization of PDSCH can be improved further.
Fig. 4 is the method flow schematic diagram of another embodiment of the present invention, the present embodiment for PUCCH feedback resource for base station configure to UE share feedback resources.See Fig. 4, the present embodiment comprises:
Step 41:eNB issues RRC information to UE, is included as the SPS information of UE configuration in this RRC information.
That UE in described group shares with step 31 unlike, the PUCCH feedback resource configured in the present embodiment.
Step 42:eNB sends through adding the control signal covered on PDCCH, comprises SPS order in this control signal, and wherein, this SPS order is used for carrying out SPS scheduling to the UE in the grouping of described UE place.In addition, eNB sends MAC PDU on PDSCH, and comprise the packet of at least one UE of this UE place grouping in this MAC PDU, this packet can be one or more MAC SDU and/or one or more MAC CE.
Step 43:UE monitors PDCCH, adopts SPS group scheduling mark solution to cover the control signal transmitted on PDCCH, and wherein, the UE in same grouping shares a SPS group scheduling mark.
Control signal after step 44:UE covers according to described solution, receives the MAC PDU on PDSCH, and described MAC PDU comprises the packet of at least one UE in the grouping of described UE place.
The particular content of step 42-44 can see step 32-34.
Step 45:UE, according to described SPS order and the reception condition to described control signal and described MAC PDU, the feedback resources indicated by the SPS information obtained in advance sends feedback information or does not feed back.
Such as, when SPS order activates/revises order for SPS, if UE successfully solution covers the control signal that PDCCH sends, and the MAC PDU of PDSCH transmission of successfully decoding, and, have oneself packet in the decoded MAC PDU of success, then by the PUCCH feedback resource of above-mentioned configuration to eNB feeding back ACK information; If UE successfully solution covers the control signal of transmission on PDCCH, and the MAC PDU of transmission on the PDSCH that successfully decodes, but, there is no oneself packet in the decoded MAC PDU of success, or, if UE successfully solution cover the control signal that PDCCH carries, but the MAC PDU that unsuccessful decoding PDSCH carries, or, if the unsuccessful solution of UE covers the control signal that PDCCH carries, then do not feed back.
Because PUCCH is shared, usually adopt the resource of special SPS release command release UE.
In the present embodiment, UE activates/revises at this SPS the MAC PDU and the data having oneself in this MAC PDU that order the PDSCH transmitted over resources of instruction follow-up successfully receiving, at the corresponding PUCCH resource feeding back ACK by calculating, if successfully receive MAC PDU but there is no oneself data, or, if UE does not successfully receive MAC PDU, then do not feed back; Simultaneously, if UE does not successfully solve MAC PDU, possible group SPS can be monitored retransmit, and carry out respective feedback in pre-configured PUCCH resource or at the relative position of the CCE (Control Channel Element, control channel unit) shared by control signal.
Such as, above pre-configured 10 PUCCH resource, the UE data of current scheduling are 2, then first UE uses first PUCCH resource, and second UE uses second PUCCH resource.
Step 46:eNB carries out respective handling according to the feedback of UE.
Such as, if eNB have sent control signal and scheduled the data of certain UE: receive ACK, think that control signal and data are all successfully received by UE; Otherwise, think that UE does not receive PDCCH, follow-up can not the data of this UE of SPS transmitted over resources of this order notice again.In order to improve reliability, when certain or some UE do not feed back, eNB can resend PDCCH order and activate, and for the UE receiving this order, this order can be understood as amendment order.
Again such as, if before for UE have sent control signal and according to judging that UE successfully receives this control signal above, the current uploading resource transmission of data just indicated at described control signal, then eNB does following judgement: if eNB scheduled the data of certain UE, receives ACK and then thinks that data are all successfully received by UE; If do not receive feedback, then think that data are not successfully received by UE, need Schedule retransmission; If eNB does not dispatch the data of certain UE, then eNB can ignore the feedback of this UE.
When eNB retransmits the data of certain or some UE, can continue to use the mode of group scheduling to dispatch the data of UE, or the mode of notice specific schedule retransmits the data of UE.
In the present embodiment, UE is at subsequently received PDSCH in this SPS resource and after having the data of oneself, feed back in the PUCCH resource of the correspondence by calculating; Meanwhile, UE can monitor possible group SPS and retransmit, and carries out respective feedback.
If UE has exited this group, or SPS business corresponding to UE is released, then this UE does not need monitoring group SPS to dispatch again, and can pass through signaling explicit notification, can judge according to configuration yet.
It is noted that because the business of different UEs is different, the SPS cycle is also different, but is meeting under certain condition, group SPS scheduling can realize the SPS group scheduling of multiple UE in different SPS cycle.Such as, some UE is the SPS cycle of 20ms, some UE is the SPS cycle of 40ms, when use group SPS dispatches, use the UE in the SPS cycle of 20ms only to need to carry out data receiver in the moment of activationary time point+20ms integral multiple, and use the UE in the SPS cycle of 40ms only to need to carry out data receiver in the moment of activationary time point+40ms integral multiple.
Under normal circumstances, same UE group SPS scheduling and special SPS scheduling (add with SPS-RNTI and cover) can not activate simultaneously.But the priority ratio group SPS optimizing scheduling level of special SPS dispatch is high, that is:
When UE is using special SPS scheduling to carry out data receiver, UE is the signaling of monitoring group SPS scheduling and data no longer;
When UE use group SPS dispatches, special SPS release command can be used to modify/discharge; After amendment, eNB and UE carries out SPS transmission according to special SPS order, follow-up same as the prior art, UE also no longer monitoring group SPS scheduling signaling and data; After release, the data before UE also no longer receives corresponding to use group SPS order, unless UE listens to group SPS activation command again.
Owing to using the usual data volume of business of SPS scheduling mode fewer, so use the UE of SPS scheduling to form one group multiple needs, use group scheduling, on the basis of reducing PDCCH expense, the resource utilization of PDSCH can be improved further.
