Fig. 3 is the method flow sketch map of another embodiment of the present invention, and present embodiment is that the feedback resources of the base station configuration special use of giving UE is an example with the PUCCH feedback resources.Referring to Fig. 3, present embodiment comprises:

Step 31:eNB issues RRC message to UE, is included as the SPS information of UE configuration in this RRC message.

Wherein, this SPS information comprises: SPS cycle and PUCCH feedback resources.In the present embodiment, be the PUCCH feedback resources of this UE configure dedicated, that is, each UE has the PUCCH feedback resources of oneself in the group.Whether UE identification is that the method that oneself has disposed special-purpose PUCCH feedback resources includes but not limited to following several kinds: whether eNB is that UE is special-purpose at this PUCCH feedback resources of RRC message indication; Or increase new parameter of distributing (promptly sharing in the group) PUCCH feedback resources of non-special use; If the PUCCH resource of using existing parameter to distribute; Then be the private resource of UE, if the PUCCH resource of distributing through new parameter then is not the private resource of UE; Or the PUCCH quantity of in RRC message, indicating as eNB is when being 1, and UE thinks that said PUCCH feedback resources is that UE is special-purpose, when quantity greater than 1 the time, think not to be special-purpose.

In addition; Can be UE configuration SPS group scheduling sign (like Group-SPS-RNTI) through RRC message also, perhaps, SPS group scheduling sign also can be the corresponding group id of beep-page message; Owing to carry group id in the beep-page message, therefore can directly this group id be identified as the SPS group scheduling; Also can be the mode that adopts static configuration, be pre-configured in the UE side.UE can adopt SPS group scheduling sign to separate the control signaling of covering out correspondence self, so that carry out Data Receiving according to separating the control signaling of covering.

Step 32:eNB sends on PDCCH through adding the control signaling of covering, and comprises the SPS order in this control signaling, and wherein, this SPS order is used for the UE in the said UE place grouping is carried out the SPS scheduling.In addition; ENB is at Physical Downlink Shared Channel (Physical Downlink Shared Channel; PDSCH) go up transmission MAC PDU, comprise the packet of at least one UE that divides into groups at this UE place among this MAC PDU, this packet can be one or more MAC service data units (MACService Data Unit; SDU) and/or one or more MAC Control Element (MAC ControlElements, CE).

Wherein, the SPS order comprises: SPS activation/modification order and SPS release command.The one or more territories that can adopt existing PDCCH to go up in the control signaling of transmitting show that this SPS order is SPS activation/modification order, or the SPS release command.For example, work as NDI=0, NDI=1 is worked as in expression SPS activation/modification order, expression SPS release command.

In the embodiment of the invention, can realize the SPS scheduling based on group, the number of the UE that promptly need dispatch is during more than one, can activate simultaneously/revise through the control signaling of PDCCH transmission or discharge the interior UE of this group.

Step 33:UE monitors PDCCH, adopts SPS group scheduling sign to separate and covers the control signaling of on PDCCH, transmitting, and wherein, the UE in the same grouping shares a SPS group scheduling sign.Wherein, the SPS group scheduling of UE side sign can be that eNB adopts the RRC message arrangement to give UE, also can be the corresponding group id of beep-page message, also can be pre-configured among the UE.

Step 34:UE receives the MAC PDU on the PDSCH according to said control signaling of separating after covering, and said MAC PDU comprises the packet of at least one UE in the said UE place grouping.

Wherein, separate and comprise UE corresponding physical channel resource in the control signaling after covering, go up and receive data so that UE can arrive the PDSCH of correspondence.

Particularly, the UE that has disposed SPS information can carry out corresponding SPS and receive operation after getting access to the SPS order.For example; If the SPS order is activation/modification order; Then UE is after receiving SPS activation/modification order; Then the time point of indication begins from the time point that receives SPS activation/modification order or SPS activations/modifications order, with SPS cycle of above-mentioned configuration be the cycle, order the mode of indicating (like employed modulation coding mode with SPS on the periodic PDSCH resource of attempting indication in the SPS order; The size of institute's data block transmitted etc.) carry out Data Receiving, and use the PUCCH resource of above-mentioned configuration to feed back according to the Data Receiving situation.If the SPS order is the SPS release command, then UE is follow-up no longer receives.

Step 35:UE is according to said SPS order and to the reception condition of said control signaling and said MAC PDU, on the indicated feedback resources of the SPS information of obtaining in advance, sends feedback information or do not feed back.

For example; When the SPS order is ordered for SPS activation/modification; If successfully separating, UE covers the control signaling that PDCCH goes up transmission; And the MAC PDU of the PDSCH that successfully decodes transmission, no matter whether the packet of oneself is arranged among the then successful decoded M AC PDU, then the PUCCH through above-mentioned configuration is to eNB feeding back ACK information; If successfully separating, UE covers the control signaling that PDCCH carries, but the MAC PDU that the PDSCH that successfully do not decode carries, then the PUCCH through above-mentioned configuration feeds back nack message to eNB; Do not cover the control signaling that PDCCH carries if UE successfully separates, then do not feed back.

Again for example, if SPS order during for the SPS release command, is then fed back according to the reception condition of control signaling, for example, when UE successfully receives this control signaling, promptly UE successfully separates and covers out the control signaling, feeding back ACK information then, otherwise, do not feed back.

Step 36:eNB carries out handled according to the feedback of UE.

For example, if dispatched the data of said UE: receive ACK then think that control signaling and data are all successfully received by UE; If receive NACK, think that then UE receives only PDCCH and do not solve PDSCH; If do not receive whatever, think that then UE does not receive PDCCH.After receiving ACK or NACK, think that UE receives PDCCH, follow-up data that can this UE of use group SPS resource transmission; If do not receive whatever, think that then UE does not receive PDCCH, the data of this UE of SPS transmitted over resources of the follow-up SPS order notice that can not on this PDCCH, transmit.Optional, in order to improve reliability, when certain or some UE did not feed back, the SPS activation command that eNB can resend on the PDCCH activated, and for the UE that receives this SPS activation command, can this SPS activation command be understood as SPS and revise order.

Wherein, after SPS successfully activated or revises, UE had the data of oneself in the follow-up MAC PDU that successfully receives in the PDSCH transmitted over resources that this SPS activation/modification order is indicated and this MAC PDU; At preset PUCCH resource feeding back ACK; If successfully receive MAC PDU but do not have 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; Can monitor the control signaling that possible SPS group scheduling sign adds the scheduling re-transmission of covering; Carry out SPS and retransmit, and on pre-configured PUCCH resource or at relative position, carry out respective feedback according to the shared CCE (Control Channel Element, control channel unit) of control signaling.Accordingly, in the eNB side, if eNB does not dispatch the data of said UE, then eNB can ignore the feedback of this UE.

Wherein, When eNB has dispatched the data of certain UE and received the NACK of UE feedback, then can dispatch re-transmission, when eNB retransmits the data of certain or some UE; The data that can continue to use the mode of group scheduling to dispatch UE perhaps notify the mode of specific schedule to retransmit the data of UE.

If UE has withdrawed from this group, or the corresponding SPS business of UE is released, and then this UE does not need the SPS of monitoring group again scheduling, can be that eNB passes through the signaling explicit notification and gives UE, also can be that UE judges according to configuration.

Being noted that of value, because different UEs is professional different, the SPS cycle is also different, but is satisfying under the certain condition, group SPS scheduling can realize the SPS group scheduling of a plurality of UE in different SPS cycles.Such as; Some UE is the SPS cycle of 20ms; Some UE is the SPS cycle of 40ms; During use group SPS scheduling, use the UE in the SPS cycle of 20ms only need carry out Data Receiving, and use the UE in the SPS cycle of 40ms only need carry out Data Receiving in the moment of activationary time point+40ms integral multiple in the moment of activationary time point+20ms integral multiple.

Generally, same UE group SPS scheduling and special-purpose SPS scheduling (add cover with SPS-RNTI) can not activate simultaneously.But the priority ratio group SPS optimizing scheduling level of special-purpose SPS dispatch is high, that is:

When UE is using special-purpose SPS scheduling to carry out Data Receiving, the signaling and the data of no longer monitoring group of UE SPS scheduling;

When UE use group SPS dispatches, can use special-purpose SPS release command to make amendment or discharge; When for modification, eNB and UE are according to special-purpose SPS order carrying out SPS transmission, and follow-up identical with prior art, UE is the signaling and the data of no longer monitoring group SPS scheduling also; When for release, use group SPS ordered pairing data before UE also no longer received, only if UE listens to group SPS activation command once more.

Owing to use the professional common data volume of SPS scheduling mode fewer, so need to use the UE of SPS scheduling to form one group, use group scheduling with a plurality of, can on the basis of minimizing PDCCH expense, further improve the resource utilization of PDSCH.

Fig. 4 is the method flow sketch map of another embodiment of the present invention, and present embodiment is that to give the feedback resources of sharing of UE be example to base station configuration with the PUCCH feedback resources.Referring to Fig. 4, present embodiment comprises:

Step 41:eNB issues RRC message to UE, is included as the SPS information of UE configuration in this RRC message.

Different with step 31 is that the PUCCH feedback resources that disposes in the present embodiment is that the UE in said group shares.

Step 42:eNB sends on PDCCH through adding the control signaling of covering, and comprises the SPS order in this control signaling, and wherein, this SPS order is used for the UE in the said UE place grouping is carried out the SPS scheduling.In addition, eNB sends MAC PDU on PDSCH, comprises the packet of at least one UE that divides into groups at this UE place among this MAC PDU, and 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 sign to separate and covers the control signaling of on PDCCH, transmitting, and wherein, the UE in the same grouping shares a SPS group scheduling sign.

Step 44:UE receives the MAC PDU on the PDSCH according to said control signaling of separating after covering, and said MAC PDU comprises the packet of at least one UE in the said UE place grouping.

The particular content of step 42-44 can be referring to step 32-34.

Step 45:UE is according to said SPS order and to the reception condition of said control signaling and said MAC PDU, on the indicated feedback resources of the SPS information of obtaining in advance, sends feedback information or do not feed back.

For example; When the SPS order is ordered for SPS activation/modification; If successfully separating, UE covers the control signaling that PDCCH goes up transmission, and the MAC PDU of the PDSCH transmission of successfully decoding, and; The packet that oneself is arranged among the success decoded M AC PDU, then the PUCCH feedback resources through above-mentioned configuration is to eNB feeding back ACK information; If successfully separating, UE covers the control signaling that PDCCH goes up transmission, and the upward MAC PDU of transmission of PDSCH that successfully decodes, still; Do not have the packet of oneself among the success decoded M AC PDU, perhaps, cover the control signaling that PDCCH carries if UE successfully separates; But the MAC PDU that the PDSCH that successfully do not decode carries; Perhaps, do not cover the control signaling that PDCCH carries, then do not feed back if UE successfully separates.

Because PUCCH shares, adopt special-purpose SPS release command to discharge the resource of UE usually.

In the present embodiment; UE has the data of oneself in the follow-up MAC PDU that successfully receives in the PDSCH transmitted over resources that this SPS activation/modification order is indicated and this MAC PDU; At corresponding PUCCH resource feeding back ACK, if successfully receive MAC PDU but do not have oneself data, perhaps through calculating; If UE does not successfully receive MAC PDU, then do not feed back; Simultaneously; If UE does not successfully solve MAC PDU; Can monitor possible group SPS and retransmit, and on pre-configured PUCCH resource or at relative position, carry out respective feedback according to the shared CCE (Control Channel Element, control channel unit) of control signaling.

Such as, above pre-configured 10 PUCCH resources, the UE data of current scheduling are 2, then first UE uses first PUCCH resource, second UE uses second PUCCH resource.

Step 46:eNB carries out handled according to the feedback of UE.

For example, if the data that eNB has sent the control signaling and dispatched certain UE: receive ACK then think that control signaling and data are all successfully received by UE; Otherwise, think that UE does not receive PDCCH, the follow-up data that can not should order this UE of SPS transmitted over resources of notice again.In order to improve reliability, when certain or some UE did not feed back, eNB can resend the PDCCH order and activate, and for the UE that receives this order, can this order be understood as and revise order.

Again for example; If sent the control signaling and successfully received this control signaling before according to top judgement UE for UE; Current transmitted over resources data of just indicating in said control signaling; Then eNB does as judging: if eNB has dispatched the data of certain UE, receive that ACK thinks that then data are all successfully received by UE; If do not receive feedback, think that then data are not successfully received by UE, need scheduling to retransmit; If eNB does not dispatch the data of certain UE, then eNB can ignore the feedback of this UE.

When eNB retransmitted the data of certain or some UE, the data that can continue to use the mode of group scheduling to dispatch UE perhaps notified the mode of specific schedule to retransmit the data of UE.

In the present embodiment, UE receives at the PDSCH on this SPS resource and after the data of oneself are arranged follow-up, feeds back in the PUCCH resource through the correspondence that calculates; Simultaneously, UE can monitor possible group SPS and retransmit, and carries out respective feedback.

If UE has withdrawed from this group, or the corresponding SPS business of UE is released, and then this UE does not need the SPS of monitoring group again scheduling, can pass through the signaling explicit notification, can judge according to configuration yet.
