Abstract

The embodiment of the invention provides a transmission method, user equipment (UE) and a base station. The method comprises the following steps that: if the UE does not receive uplink (UL)-grant corresponding to a physical uplink shared channel (PUSCH) of the highest priority, which is determined in advance, UE determines the current PUSCH of the highest priority, multiplexes acknowledgement (ACK) or negative acknowledgement (NACK) which is needed to be sent by the current subframe, and uplink data on the current PUSCH of the highest priority, then sends the multiplexed ACK or NACK and uplink data to the base station, and reserves the resources of ACK or NACK on other PUSCHs to ensure that the base station detects data on the basis of the existing condition of the resources of ACK or NACK. In the method, the UE and the base station send or detect data on the determined and same resources, so that the data detection errors caused by wrong rate matching modes can be avoided.

Embodiment

For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

In Long Term Evolution (Long Term Evolution is called for short LTE) system, base station and UE carry out transfer of data on a carrier wave.By base station scheduling to UE in each subframe, can comprise self Physical Downlink Control Channel (Physical Downlink Control Channel, be called for short PDCCH), PDCCH can be descending scheduling mandate (DL_grant) or, descending scheduling mandate and uplink scheduling authorization have carried respectively indication Physical Downlink Shared Channel (Physical DownlinkShared Channel, be called for short PDSCH) or the schedule informations such as time-frequency resource allocating of PUSCH, UE receives and decodes after PDCCH, by PDSCH downlink data receiving or send upstream data by PUSCH.If UE has correctly received after downlink data, to base station feedback uplink ACK; If UE does not have correct downlink data receiving, to the up NACK of base station feedback.If base station has correctly received the upstream data that UE sends, to UE feeding back downlink ACK; If base station does not have correctly to receive the upstream data that UE sends, to UE feeding back downlink NACK.

When not having upstream data to send, uplink ACK or NACK are carried on Physical Uplink Control Channel (PUCCH).When having upstream data to send, uplink ACK or NACK can, together with upstream data, transmit on PUSCH so that time-multiplexed mode is multiplexing.Particularly, be to place upstream data in the resource of first distributing at eNB, with uplink ACK or NACK, data are punched uplink ACK or NACK and data-reusing afterwards, that is, some part in data is got rid of, with uplink ACK or NACK, fill these parts.In LTE system, do not allow to send two or more waveforms simultaneously, can keep single-carrier property like this.

Base station needs to carry out dispatching downlink data according to the channel condition information obtaining from UE (Channel StatusInformation is called for short CSI).CSI comprises channel quality indication (ChannelQuality Indication is called for short CQI), pre-coding matrix indication (Precoding Matrix Indicator is called for short PMI) and grade indication (Rank Indication is called for short RI).

In LTE system, the CSI that UE feeds back to base station comprises periodically CSI and aperiodicity CSI.

Periodically the cycle of CSI is that RRC signal deployment is passed through to UE in base station.When UE does not have upstream data to send, periodically CSI can be carried on PUCCH.While having UE to have upstream data to send, periodically CSI with upstream data together, transmits on PUSCH so that time-multiplexed mode is multiplexing.

Can trigger bit by one in UL_grant and trigger aperiodicity CSI.If trigger bit, be set to 0, represent not need UE feedback aperiodicity CSI, if trigger bit, be set to 1, represent to need UE feedback aperiodicity CSI.When UE has upstream data to send, aperiodicity CSI can, together with upstream data, transmit on PUSCH so that time-multiplexed mode is multiplexing.When UE does not have upstream data, UE can send aperiodicity CSI by PUSCH.

In LTE system, when UE had at a time both needed to send periodically CSI, while needing again to send aperiodicity CSI, UE can only send aperiodicity CSI because aperiodic CSI priority higher than periodicity CSI.

Periodically or aperiodicity CSI and upstream data with multiplexing while transmitting on PUSCH together with time-multiplexed mode, periodicity or aperiodicity CSI and upstream data are to shine upon respectively resource on PUSCH, in the resource of specifically distributing at eNB, first place CSI, then place upstream data.

The LTE system (LTE-A) of evolution is supported carrier aggregation technology (Carrier Aggregation, be called for short CA), a plurality of member carriers (Component Carrier is called for short CC) can be distributed to a UE simultaneously, to improve the message transmission rate of UE.

In LTE-A system, on up direction, can send two or more waveforms simultaneously.This point is different with LTE system, in LTE system, can not send two or more waveforms simultaneously.

In LTE-A system, UE can support a plurality of PUSCH to transmit simultaneously, and can support PUSCH and PUCCH to transmit simultaneously.

The flow chart that is illustrated in figure 1 transmission method embodiment mono-of the present invention, comprising:

Step 101, UE have judged whether to receive UL_grant corresponding to PUSCH that predetermined priority is the highest;

If UE does not receive UL_grant corresponding to PUSCH that predetermined priority is the highest, UE execution step 102, step 102 comprise the steps (a1), (a2) and (a3) in a kind of:

(a1) if UE need to send success message ACK or send failed message NACK in current subframe, UE determines the PUSCH that current priority is the highest, upstream data corresponding to PUSCH that the ACK that UE need to be sent in current subframe or NACK are the highest with current priority multiplexingly sends to base station on the highest PUSCH of current priority; In PUSCH corresponding to each UL-grant that UE in current subframe is received, the upstream data corresponding to PUSCH of other except the highest PUSCH of current priority, on other the PUSCH except the highest PUSCH of current priority, send to base station respectively, and on other the PUSCH except the highest PUSCH of current priority the resource of reserved ACK or NACK.

(a2) if UE need to send periodical channel state information CSI in current subframe, PUSCH that each UL-grant that UE receives UE in current subframe is corresponding is upper sends to base station by upstream data, the resource of reservation period CSI not on PUSCH corresponding to UE receives in current subframe each UL-grant.

(a3) if UE need to send periodically CSI in current subframe, and need to send ACK or NACK, UE determines the PUSCH that current priority is the highest, the ACK that current subframe need to be sent or NACK, the multiplexing base station that sends on the highest PUSCH of current priority of upstream data that the PUSCH the highest with current priority is corresponding, the not resource of reservation period CSI; In PUSCH corresponding to each UL-grant that UE in current subframe is received, the upstream data corresponding to PUSCH of other except the highest PUSCH of current priority, on other the PUSCH except the highest PUSCH of current priority, send to base station respectively, and the resource of reserved ACK or NACK, the not resource of reservation period CSI on other the PUSCH except the highest PUSCH of current priority; Or the resource of reserved ACK or NACK, the not resource of reservation period CSI on other the PUSCH except the highest PUSCH of current priority.

In embodiment as shown in Figure 1, if UE has received UL_grant corresponding to PUSCH that predetermined priority is the highest, UE can perform step 103.

Step 103 specifically can comprise the steps (b1), (b2) and (b3) in a kind of:

The flow chart that is illustrated in figure 2 transmission method embodiment bis-of the present invention, comprising:

Step 201, base station have judged whether to dispatch the highest PUSCH of predetermined priority.

If the highest PUSCH of predetermined priority is not dispatched in base station, base station execution step 202, step 202 can comprise the steps (c1), (c2) and (c3) in a kind of:

(c1) if base station need to receive in current subframe ACK or the NACK that UE sends, the highest PUSCH of current priority in the PUSCH having dispatched is determined in base station, on the highest PUSCH of current priority, detect ACK or NACK, and detection data corresponding to PUSCH the highest with current priority; In the PUSCH having dispatched, the PUSCH of other except the highest PUSCH of current priority is upper, and the condition that the resource based on ACK or NACK exists detects other data corresponding to PUSCH except the highest PUSCH of current priority.

(c2), if base station need to receive in current subframe the periodicity CSI that UE sends, base station non-existent condition of the resource based on periodicity CSI on the PUSCH having dispatched, detects the data corresponding to PUSCH of having dispatched.

(c3) if base station need to receive in current subframe ACK or the NACK that UE sends, and need to receive the periodicity CSI that UE sends, the highest PUSCH of current priority in the PUSCH having dispatched is determined in base station, the non-existent condition of resource based on periodicity CSI on the highest PUSCH of current priority, detect ACK or NACK, and detection data corresponding to PUSCH the highest with current priority; In the PUSCH having dispatched, on the PUSCH of other except the highest PUSCH of current priority, resource based on ACK or NACK exists and the non-existent condition of resource of CSI periodically, detects other data corresponding to PUSCH except the highest PUSCH of current priority.

In embodiment bis-, if the highest PUSCH of predetermined priority of base station scheduling, base station execution step 203, step 203 can comprise the steps (d1), (d2) and (d3) in a kind of:

(d1) if base station need to receive in current subframe ACK or the NACK that UE sends, ACK or NACK are detected in base station on the highest PUSCH of predetermined priority, and detection data corresponding to PUSCH the highest with predetermined priority; In the PUSCH having dispatched, on the PUSCH of other except the highest PUSCH of predetermined priority, the condition that resource based on ACK or NACK exists, detects this other data corresponding to PUSCH except the highest PUSCH of predetermined priority.

(d2) if base station need to receive in current subframe the periodicity CSI that UE sends, base station sense cycle CSI on the highest PUSCH of predetermined priority, and detection data corresponding to PUSCH the highest with predetermined priority, in the PUSCH having dispatched, on the PUSCH of other except the highest PUSCH of predetermined priority, the non-existent condition of resource based on periodicity CSI, detects this other data corresponding to PUSCH except the highest PUSCH of current priority.

(d3) if base station need to receive in current subframe the periodicity CSI that UE sends, and need to receive ACK or NACK that UE sends, base station is on the highest PUSCH of predetermined priority, sense cycle CSI, detect ACK or NACK, and detection data corresponding to PUSCH the highest with predetermined priority; On the PUSCH of other in the PUSCH having dispatched except the highest PUSCH of predetermined priority, resource based on ACK or NACK exists and the non-existent condition of resource of CSI periodically, detects the data corresponding with other PUSCH except the highest PUSCH of predetermined priority.

The implementation procedure of above-described embodiment one and embodiment bis-is described below by concrete example.

When base station and UE carry out transfer of data, in each subframe, which UCI UE need to feed back to base station, and base station can know, UE also can be known.UCI can comprise periodically CSIACK and NACK.

Predetermined priority arrangement can be as follows: PUSCH-A > PUSCH-B > PUSCH-C > PUSCH-D > PUSCH-E.About this priority arrangement, can be by standard predefine, or can by high-level signaling or physical layer signaling, be configured to UE by base station.

(1) for (a1), (b1), (c1) and (d1) for example

Step (a1), (b1), (c1) and (d1) be in current subframe, need to send ACK or NACK to the situation of base station for UE.

When UE is when current subframe need to send ACK or NACK, UE has judged whether to receive UL-grant corresponding to PUSCH that predetermined priority is the highest.If UE is undetected UL-grant corresponding to PUSCH-A, UE can determine and not receive UL-grant corresponding to PUSCH that predetermined priority is the highest.

At this moment, UE can determine the PUSCH that current priority is the highest.In the embodiment of the present invention, for UE, the PUSCH that current priority is the highest is in the PUSCH that all UL-grant of receiving of UE are corresponding, according to predetermined priority arrangement, priority is the highest one.

Suppose base station at current subframe scheduling PUSCH-A, PUSCH-B, PUSCH-D and PUSCH-E, if UE is undetected UL-grant corresponding to PUSCH-A, UE has received only PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, according to above-mentioned priority arrangement, that current priority is the highest should be PUSCH-B.

In step (a1), if UE has received PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and UE does not receive the UL-grant that PUSCH-A is corresponding, UE can determine that the PUSCH that current priority is the highest is PUSCH-B, the ACK that current subframe need to be sent or NACK, the multiplexing base station that sends on PUSCH-B of the upstream data corresponding with PUSCH-B, concrete multiplex mode can be the mode that adopts punching.And, UE is by PUSCH corresponding to each UL-grant receiving in current subframe, the upper corresponding upstream data of PUSCH of other except PUSCH-B sends to base station respectively, and on other PUSCH, reserves the resource of ACK or NACK on other PUSCH.That is, on PUSCH-D and PUSCH-E, send upstream data to base station respectively, and on PUSCH-D and PUSCH-E, reserve the resource of ACK or NACK.

In step (b1), if UE has received PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and UE has received UL-grant corresponding to PUSCH-A, ACK or NACK that UE need to send current subframe, and the multiplexing base station that sends on PUSCH-A of upstream data corresponding to PUSCH-A, on PUSCH-B, PUSCH-D and PUSCH-E, send upstream data, and the resource of reserved ACK or NACK.

In step (c1), if base station scheduling PUSCH-B, PUSCH-D and PUSCH-E, and PUSCH-A is not dispatched in base station, base station determine current priority the highest be PUSCH-B, ACK or NACK are detected in base station on PUSCH-B, and detect data.Under the condition that resource based on ACK or NACK on PUSCH-D and PUSCH-E exists, detect data.

In step (d1), base station scheduling PUSCH-A, PUSCH-B, PUSCH-D and PUSCH-E, ACK or NACK are detected in base station on PUSCH-A, and detect data, under the condition that the resource based on ACK or NACK on PUSCH-B, PUSCH-D and PUSCH-E exists, detect data.

For base station, base station uncertain UE have received UL-grant corresponding to which PUSCH, undetected UL-grant corresponding to which PUSCH.UE also uncertain base station scheduling which UL-grant.

Adopt method of the prior art, can cause the Data Detection mistake of bringing due to wrong rate-matched mode.

For example, two UL_grant difference dispatching uplink P-PUSCH and up S-PUSCH for base station, UE has UCI to need to send just while sending PUSCH, and UE is multiplexed into the upper transmission of P-PUSCH by UCI, because according to aforementioned prioritization, the priority of P-PUSCH is greater than the priority of S-PUSCH.

If UE the is undetected UL-grant of dispatching uplink P-PUSCH, and only received the UL_grant of dispatching uplink S-PUSCH, UE can be multiplexed into S-PUSCH above UCI so, and does not send whatever on P-PUSCH, neither sends upstream data and does not also send UCI.And upstream data can be detected in base station on S-PUSCH, on P-PUSCH, detect UCI and upstream data.

Because UE does not send whatever on P-PUSCH, if UCI is detected according to existing mode in base station on P-PUSCH, wrong UCI and wrong upstream data can be detected.

Because UE is by UCI and upstream data is multiplexing transmits on S-PUSCH, if base station, according to existing mode, is only detected data, and do not considered UCI on S-PUSCH, base station can detect wrong data.Because UCI and upstream data are multiplexing to be transmitted on S-PUSCH, should consider the existence of UCI, and demodulating data is still carried out according to the rate-matched mode of only having data in base station during rate-matched, wrong upstream data can be detected.

Base station detects after upstream data, and UE data retransmission can be waited for upstream data buffer memory in base station, and the data of the data that UE is retransmitted and buffer memory merge.Because base station is detected by wrong rate-matched and buffer memory upstream data, can cause follow-up merging and retransmit a series of mistake occurs.

The method that adopts the embodiment of the present invention to provide, if current subframe UE need to send ACK or NACK to base station, UE is according to different situations so, can perform step (a1) or (b1), on each PUSCH, all reserve the resource of ACK or NACK, for the highest PUSCH of predetermined priority or the highest PUSCH of current priority, UE has not only reserved the resource of ACK or NACK, has also sent ACK or NACK; Base station is according to different situations, can perform step (c1) or (d1), the condition that while detecting data on each PUSCH, all the resource based on ACK or NACK exists detects (even if detect ACK or NACK in predetermined priority, being also that the condition that the resource based on ACK or NACK exists detects in fact).That is to say, although which PUSCH the uncertain UE in base station is carried at by ACK or NACK, UE also uncertain base station can detect ACK or NACK on which PUSCH, but, base station and UE send or detect data in definite, identical resource, rather than in inconsistent resource, send or detection data, no matter UE sends ACK or NACK on which PUSCH, mistake that can generation rate matching way when data are detected in base station, thereby the Data Detection mistake that can avoid the mode due to rate-matched to cause.

In addition, in the resource of reserved ACK or NACK, UE can send ACK or NACK, and for example, for step (a1), UE, except can send ACK or NACK on PUSCH-B, also can send ACK or NACK on PUSCH-D and PUSCCH-E.

In step (d1), ACK or NACK can also be in the PUSCH having dispatched be detected on the PUSCH of other except the highest PUSCH of predetermined priority in base station, the ACK that each PUSCH from having dispatched is detected or the likelihood value of NACK compare, select likelihood value maximum, or select likelihood value to surpass ACK on PUSCH certain threshold value, that there is limit priority or NACK as ACK or the NACK of UE feedback in current subframe.

For example, the ACK that base station can detect from PUSCH-A, PUSCH-B, PUSCH-D and PUSCH-E or the likelihood value of NACK compare, select likelihood value maximum, or select likelihood value to surpass ACK on PUSCH certain threshold value, that there is limit priority or NACK as ACK or the NACK of UE feedback in current subframe.

In this way, even if which PUSCH the uncertain UE in base station has been carried at above by ACK or NACK, base station still can correctly detect ACK or NACK.

(a1) (b1) (c1) and (d1) in, that need that UE sends is ACK or NACK, therefore, does not relate to the problem of the resource of CSI.

(2) for (a2), (b2), (c2) and (d2) for example

Step (a2) is (c2) and (d2) be in current subframe, need to send periodically CSI to the situation of base station for UE (b2).

In step (a2), if UE has received PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and do not receive the UL-grant that PUSCH-A is corresponding.When current subframe UE need to send periodicity CSI, UE sends upstream data to base station respectively on PUSCH-B, PUSCH-D and PUSCH-E, and the resource of reservation period CSI not on PUSCH-B, PUSCH-D and PUSCH-E, that is to say, in current subframe, to base station, do not send periodically CSI, but only sent upstream data to base station.

In step (b2), if UE has received PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and receive UL-grant that PUSCH-A is corresponding when current subframe UE need to send periodically CSI, the multiplexing base station that sends to of upstream data that the periodicity CSI that UE need to send current subframe and PUSCH-A are corresponding on PUSCH-A.On PUSCH-B, PUSCH-D and PUSCH-E, send upstream data to base station, and on PUSCH-B, PUSCH-D and PUSCH-E the resource of reservation period CSI not.

In step (c2), if base station scheduling PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and do not dispatch PUSCH-A, resource based on periodicity CSI on PUSCH-B, PUSCH-D and PUSCH-E non-existent condition in base station detects data so.

In step (d2), if base station scheduling PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and dispatched PUSCH-A, base station sense cycle CSI and data on PUSCH-A so, the non-existent condition of resource based on periodicity CSI on PUSCH-B, PUSCH-D and PUSCH-E detects data.

The method that adopts the embodiment of the present invention to provide, if current subframe UE need to send periodically CSI to base station, UE is according to different situations so, can perform step (a2) or (b2), base station is according to different situations, can perform step (c2) or (d2).Although the uncertain UE in base station is carried at periodicity CSI on which PUSCH, UE also uncertain base station can detect ACK or NACK on which PUSCH, but, base station and UE send or detect data in definite, identical resource, rather than in inconsistent resource, send or detection data, no matter UE sends periodically CSI on which PUSCH, mistake that can generation rate matching way when data are detected in base station, thereby the Data Detection mistake that can avoid the mode due to rate-matched to cause.

At (a2) with (c2), that need UE transmission is periodicity CSI, therefore, does not relate to the problem of the resource of ACK or NACK.

(3) for (a3), (b3), (c3) and (d3) for example

Step (a3) (a3), (b3), (c3) and (d3) be to need UE to send ACK or NACK for current subframe, and need to send periodically CSI to the situation of base station.

In step (a3), if UE has received PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and do not receive the UL-grant that PUSCH-A is corresponding.When current subframe UE need to send ACK or NACK, and while needing to send periodicity CSI, the ACK that UE need to send current subframe or NACK, the multiplexing base station that sends on PUSCH-B of the upstream data corresponding with PUSCH-B, the resource of reservation period CSI not on PUSCH-B.On PUSCH-D and PUSCH-E, send data, and on PUSCH-D and PUSCH-E the resource of reserved or reserved ACK or NACK, the also resource of reservation period CSI not.

In step (b3), if UE has received PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and receive the UL-grant that PUSCH-A is corresponding, when current subframe UE need to send periodically ACK or NACK, and while needing to send periodicity CSI, the ACK that UE need to send current subframe or NACK, and periodicity CSI and the multiplexing base station that sends on PUSCH-A of upstream data corresponding to PUSCH-A.On PUSCH-B, PUSCH-D and PUSCH-E, send upstream data to base station, and on PUSCH-B, PUSCH-D and PUSCH-E, reserve or do not reserve the resource of ACK or NACK, the not resource of reservation period CSI.

In step (c3), if base station scheduling PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and do not dispatch PUSCH-A, resource based on periodicity CSI on PUSCH-B non-existent condition in base station detects ACK or NACK so, and detects data.Base station resource based on ACK or NACK on PUSCH-D and PUSCH-E exists and the non-existent condition of resource of periodicity CSI detects data.

In step (d3), if base station scheduling PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and dispatched PUSCH-A, base station sense cycle CSI and data on PUSCH-A so, and detect ACK or NACK.Base station resource based on ACK or NACK on PUSCH-B, PUSCH-D and PUSCH-E exists and the non-existent condition of resource of periodicity CSI detects data.

In step (d3), ACK or NACK can also be in the PUSCH having dispatched be detected on the PUSCH of other except the highest PUSCH of predetermined priority in base station, the ACK that each PUSCH from having dispatched is detected or the likelihood value of NACK compare, select likelihood value maximum, or select likelihood value to surpass ACK on PUSCH certain threshold value, that there is limit priority or NACK as ACK or the NACK of UE feedback in current subframe.

The method that adopts the embodiment of the present invention to provide, if current subframe UE need to send periodicity CSI to base station, and need to send ACK or NACK, UE is according to different situations so, can perform step (a3) or (b3), base station is according to different situations, can perform step (c3) or (d3).Although the uncertain UE in base station is carried at periodicity CSI and ACK or NACK on which PUSCH, UE also uncertain base station can detect ACK or NACK on which PUSCH, and periodicity CSI, but, base station and UE are determining, in identical resource, send or detect data, rather than in inconsistent resource, send or detection data, no matter UE sends periodically CSI on which PUSCH, and ACK or NACK, mistake that can generation rate matching way when data are detected in base station, thereby the Data Detection mistake that can avoid the mode mistake due to rate-matched to cause.

The embodiment of the present invention also provides a kind of transmission method, can comprise the steps:

When current subframe need to send ACK or NACK, UE is by ACK or NACK and upstream data is multiplexing on the highest PUSCH of predetermined priority, sends to base station, or by ACK or NACK and upstream data is multiplexing sends to base station on the highest PUSCH of current priority, on other PUSCH, send upstream data, and the resource of not reserved ACK or NACK.

When UE need to send ACK or NACK in current subframe, and periodically during CSI, UE is by ACK or NACK, and periodicity CSI upstream data multiplexing on predetermined PUSCH send to base station corresponding to PUSCH the highest with predetermined priority, in each UL-grant receiving at UE, except PUSCH corresponding to predetermined priority, on corresponding PUSCH, all do not reserve the resource of ACK or NACK.

When base station is when current subframe need to receive ACK that UE sends or NACK, ACK or NACK are first detected in base station, likelihood value is compared, or likelihood value is surpassed to ACK on the highest PUSCH of priority of certain threshold value or NACK as ACK or the NACK of UE feedback, the normal upstream data that detects on other PUSCH, does not need the resource of supposing ACK or NACK to exist.

When base station need to receive in current subframe ACK or the NACK that UE sends, and in the time of need to receiving the periodicity CSI of UE transmission, base station at current subframe scheduling each PUSCH on first detect ACK or NACK, likelihood value is compared, or likelihood value is surpassed to ACK on the highest PUSCH of priority of certain threshold value or NACK as ACK or the NACK of UE feedback, follow sense cycle CSI and upstream data on this PUSCH, the normal upstream data that detects on other PUSCH, do not need the resource of supposing ACK or NACK to exist, do not need the resource of assumption period CSI exist or do not exist yet.

Be illustrated in figure 3 the flow chart of transmission method embodiment tri-of the present invention, this embodiment tri-also comprises on the basis of embodiment mono-:

The number of the current PUSCH being scheduled that step 100-1, UE judgement base station sends is 1 or is greater than 1.If the number of the current PUSCH being scheduled that base station sends is 1, execution step 100-2; If the number of the current PUSCH being scheduled that base station sends is greater than 1, execution step 101.

At least one in the periodicity CSI that step 100-2, UE need to send current subframe, ACK and NACK sends to base station on the current PUSCH being scheduled.

In embodiment tri-, if the number of the PUSCH of base station scheduling only has one in current subframe, so no matter whether this PUSCH being scheduled is the highest PUSCH of predetermined priority, and periodicity CSI, the ACK that UE can need to send current subframe and at least one in NACK send to base station by this PUSCH being scheduled in current subframe.

Be illustrated in figure 4 the flow chart of transmission method embodiment tetra-of the present invention, this embodiment tetra-also comprises on the basis of embodiment bis-:

Step 200-1, base station judge current subframe scheduling the number of PUSCH equal 1 and be still greater than 1.If current subframe scheduling the number of PUSCH equal 1, execution step 200-2; If current subframe scheduling the number of PUSCH be greater than 1, execution step 201.

Step 200-2, base station at current subframe scheduling PUSCH at least one in sense cycle CSI, ACK and NACK, and detect data.

In embodiment tetra-, if the number of the PUSCH of base station scheduling only has one in current subframe, so no matter whether this PUSCH being scheduled is the highest PUSCH of predetermined priority, base station can be at current subframe scheduling PUSCH at least one in sense cycle CSI, ACK and NACK, and detect data.

In aforementioned each embodiment, if UE has reserved the resource of ACK or NACK, UE can send ACK or NACK in reserved resource, also can not send ACK or NACK.Preferably scheme can be in reserved resource, to send ACK or NACK.

ACK or NACK can be in the PUSCH having dispatched be detected on except the highest PUSCH of predetermined priority in base station, the ACK that each PUSCH from having dispatched is detected or the likelihood value of NACK compare, select likelihood value maximum or likelihood value surpass ACK on the PUSCH of limit priority of certain threshold value or NACK as ACK or the NACK of UE feedback in current subframe.

The implementation procedure of above-described embodiment four and embodiment five is described below by concrete example.

When base station and UE carry out transfer of data, in each subframe, which UCI UE need to feed back to base station, and base station can know, UE also can be known.UCI can comprise periodically CSI, aperiodicity CSI, ACK and NACK.

Predetermined priority arrangement can be as follows: PUACH-A > PUSCH-B > PUSCH-C > PUSCH-D > PUSCH-E.About this priority arrangement, between base station and UE, can consult in advance, or can be configured to UE by base station.

(1) for (e1), (e4), (f1), (g1), (h1), (h4), (I1) and (J1) for example

Step (e1), (e4), (f1), (g1), (h1), (h4), (I1) and (J1) be to need UE to send ACK or NACK to the situation of base station for current subframe.

Suppose base station at current subframe scheduling PUSCH-A, PUSCH-B, PUSCH-D and PUSCH-E, PUSCH-D is for triggering the UL-grant of UE feedback aperiodicity CSI.If UE is undetected UL-grant corresponding to PUSCH-A, UE has received only PUSCH-B, PUSCH-D and UL-grant corresponding to PUSCH-E, and according to above-mentioned priority arrangement, that current priority is the highest should be PUSCH-B.

In step (e1), if UE has received PUSCH-B, the UL-grant that PUSCH-D and PUSCH-E are corresponding, for triggering the UL-grant of UE feedback aperiodicity CSI, be the UL-grant that PUSCH-D is corresponding, and UE does not receive the UL-grant that PUSCH-A is corresponding, when current subframe need to send ACK or NACK, UE can determine that the PUSCH that current priority is the highest is PUSCH-B, the ACK that current subframe need to be sent or NACK, the multiplexing base station that sends on PUSCH-B of the upstream data corresponding with PUSCH-B, concrete multiplex mode can be the mode that adopts punching.And, the upper corresponding upstream data of PUSCH of UE other except PUSCH-B by PUSCH corresponding to each UL-grant receiving in current subframe, on other PUSCH, send to base station respectively, and on other PUSCH, reserve the resource of ACK or NACK.That is, on PUSCH-D and PUSCH-E, send upstream data to base station respectively, and on PUSCH-D and PUSCH-E, reserve the resource of ACK or NACK.

The method that adopts the embodiment of the present invention to provide, if current subframe UE need to send ACK or NACK to base station, UE is according to different situations so, can perform step (e3), (e7), (e8), (f4), (f5), (g4) or (g5); Base station is according to different situations, can perform step (h3), (h7), (h8), (I4), (I5), (J4) or (J5); .Although the uncertain UE in base station is by ACK or NACK, or which PUSCH aperiodicity CSI is carried at, UE also uncertain base station can detect ACK or NACK on which PUSCH, or aperiodicity CSI, but, base station and UE are determining, in identical resource, send or detect data, rather than in inconsistent resource, send or detection data, no matter UE sends ACK or NACK on which PUSCH, or aperiodicity CSI, mistake that can generation rate matching way when data are detected in base station, thereby the Data Detection mistake that can avoid the mode due to rate-matched to cause.

Be illustrated in figure 7 the flow chart of transmission method embodiment seven of the present invention, this embodiment six also comprises on the basis of embodiment five:

The number 1 of the current PUSCH being scheduled that step 300-1, UE judgement base station sends is still greater than 1.If the number of the current PUSCH being scheduled that base station sends is 1, execution step 300-2; If the number of the current PUSCH being scheduled that base station sends is greater than 1, execution step 301.

At least one in the aperiodicity CSI that step 300-2, UE need to send current subframe, ACK and NACK, sends to base station with upstream data is multiplexing at the current PUSCH being scheduled; The resource of reservation period CSI not on the current PUSCH being scheduled; Or the resource of the periodicity CSI of the descending carrier that the aperiodicity CSI that reserved current subframe need to be fed back is corresponding, upstream data that all the other that current subframe need to be sent the PUSCH that periodically CSI are the highest with current priority is corresponding is multiplexing sends to base station on the current PUSCH being scheduled.

In embodiment seven, if the number of the PUSCH of base station scheduling only has one in current subframe, so no matter whether this PUSCH being scheduled is the highest PUSCH of predetermined priority, and periodicity CSI, the ACK that UE can need to send current subframe and at least one in NACK send to base station by this PUSCH being scheduled in current subframe.

Be illustrated in figure 8 the flow chart of transmission method embodiment eight of the present invention, this embodiment six also comprises on the basis of embodiment six:

Step 400-1, base station judge current subframe scheduling the number of PUSCH be 1 or be greater than 1.If current subframe base station scheduling the number of PUSCH be 1, and for trigger PUSCH corresponding to UL-grant of UE feedback aperiodicity CSI be current subframe by base station scheduling PUSCH, perform step 400-2.If current subframe base station scheduling the number of PUSCH be greater than 1, perform step 401.

Step 400-2, base station in current subframe by base station scheduling PUSCH on the non-existent condition of resource based on periodicity CSI detect at least one in aperiodicity CSI, ACK and NACK, and detect data; Or base station in current subframe by base station scheduling PUSCH on the non-existent condition of resource of periodicity CSI of descending carrier corresponding to the aperiodicity CSI that need to feed back based on current subframe detect at least one in aperiodicity CSI, ACK and NACK, and detect data and except when the CSI periodically of other outside the periodicity CSI of descending carrier corresponding to aperiodicity CSI that front subframe need to be fed back.

In aforementioned each embodiment, if UE has reserved the resource of ACK or NACK, UE can send ACK or NACK in reserved resource, also can not send ACK or NACK.

In aforementioned each embodiment, the number that base station sends to the current PUSCH being scheduled of UE, can carry by UL_grant, and also (as RRC or MAC contour level signaling) carries by other means.Concrete grammar can be a kind of in following method:

(1) can in PDCCH, increase a bit, for representing that the number of the current PUSCH being scheduled is 1 or is greater than 1.For example, this newly-increased bit is set to 1, represents that the number of the current PUSCH being scheduled is greater than 1, and this newly-increased bit is set to 0, represents that the number of the current PUSCH being scheduled equals 1.

(2) a UL_grant signaling format 0 ' can be set, combine differentiation with existing UL_grant form 0 and DL_grant form 1A.For example, Head Section proportion by subtraction is specially for 0 presentation format 0, and Head Section proportion by subtraction is specially for 10 presentation format 1A, and Head Section proportion by subtraction is specially for 11 presentation formats 0 '.Now can represent that the number of the current PUSCH being scheduled is 1, represents that with UL_grant form 0 number of the current PUSCH being scheduled is greater than 1 with UL_grant form 0 '; Or vice versa.

(3) can with PDCCH, implicitly carry the information of the number of the current PUSCH being scheduled, for example, can adopt the mode of CRC scrambling to represent the number of the current PUSCH being scheduled.Concrete, with scrambler 1, come the CRC of scrambling PDCCH to represent that the current PUSCH number being scheduled is 1, with scrambler 2, come the CRC of scrambling PDCCH to represent that the current PUSCH number being scheduled is greater than 1, vice versa; Can adopt the CCE label of PDCCH in search volume to represent the number of the current PUSCH being scheduled.Concrete, the PDCCH that takies the initial CCE label of odd number in search volume represents that the current PUSCH number being scheduled is 1, and the PDCCH that takies the initial CCE label of even number in search volume represents that the current PUSCH number being scheduled is greater than 1, and vice versa; Can adopt the label of Resource Block of the PUSCH of PDCCH scheduling to represent the number of the current PUSCH being scheduled.Concrete, the initial Physical Resource Block of odd number that the PUSCH of scheduling takies represents that the current PUSCH number being scheduled is 1, the initial Physical Resource Block of even number that the PUSCH of scheduling takies represents that the current PUSCH number being scheduled is greater than 1.

(4) to indicate the current PUSCH number being scheduled be 1 or be greater than 1 can to trigger with CSI aperiodic in UL_grant form 0 bit.Specifically be divided into two scenes as follows:

(4a) scene: restriction CSI aperiodic and periodicity CSI cannot occur simultaneously.

When not being the moment that periodically CSI need to feed back, CSI aperiodic in UL_grant form 0 triggers bit can be as normal CSI triggering aperiodic; When to the moment that periodically CSI need to feed back, CSI aperiodic in UL_grant form 0 triggers bit and is just not used as CSI triggering aperiodic, and be 1 or be greater than 1 as the current PUSCH number being scheduled of indication, for example being set to the current PUSCH number being scheduled of 0 expression is 1, be set to the current PUSCH number being scheduled of 1 expression and be greater than 1, vice versa.

(4b) scene: aperiodic and cycle, CSI can occur simultaneously.

To indicate the current PUSCH number being scheduled be 1 or be for example greater than 1. with CSI aperiodic in UL_grant form 0, to trigger bit, it is 1 that this triggering bit is set to the current PUSCH number being scheduled of 0 expression, be set to the current PUSCH number being scheduled of 1 expression and be greater than 1, vice versa.

Now, aperiodic, whether the triggering of CSI can indicate by other method, for example:

Can adopt the mode of CRC scrambling to represent that current aperiodic, whether CSI triggered.Concrete, with scrambler 1, come the CRC of scrambling PDCCH to represent that current aperiodic, CSI was not triggered, with scrambler 2, come the CRC of scrambling PDCCH to represent that current aperiodic, CSI was triggered, vice versa.

Or, can adopt the CCE label of PDCCH in search volume to represent that current aperiodic, whether CSI triggered.Concrete, the PDCCH that takies the initial CCE label of odd number in search volume represents that current aperiodic, CSI was not triggered, and the PDCCH that takies the initial CCE label of even number in search volume represents that current aperiodic, CSI was triggered, and vice versa.

Or, can adopt the label of Resource Block of the PUSCH of PDCCH scheduling to represent that current aperiodic, whether CSI triggered.Concrete, the initial Physical Resource Block of odd number that the PUSCH of scheduling takies represents that current aperiodic, CSI was not triggered, and the initial Physical Resource Block of even number that the PUSCH of scheduling takies represents that current aperiodic, CSI was triggered.

Or, can adopt state in modulation coding mode in PDCCH (Modulation Coding Scheme, be called for short MCS) field to represent that current aperiodic, whether CSI triggered.Concrete, when dispatching uplink new data packets, MCS in PDCCH can be set to 29 or 30 or 31 and represent that current aperiodic, CSI was triggered, now modulation system can be defaulted as QPSK or 16QAM or 64QAM, select the code rate (code rate can be that standard is predefined, or is configured to UE by eNB) of acquiescence; When dispatching uplink retransmission data packet may, MCS value in PDCCH can be set to a kind of in 0 to 28 and represent that current aperiodic, CSI was triggered, identical when now the resource of retransmission data packet may and MCS can be with this packet initial schedule or last re-transmissions, or, if when the distribution of the resource of current notice and MCS have guaranteed that the transmission block size of this packet is constant, this retransmission packet also can be used in the resource of current PDCCH notice and distribute and MCS.

In the situation that having, a plurality of PUSCH that support for UE may not have prioritization.If UE is undetected certain UL_grant, UE carries the PUSCH of UCI and PUSCH that base station is prepared detection in advance may not be same, can cause like this base station to detect data and make a mistake.For example, if base station has sent two UL_grant, correspond respectively to a PUSCH and the 2nd PUSCH.If UE the is undetected UL_grant corresponding with a PUSCH, UCI can be carried to the 2nd PUSCH upper for UE so, and UCI and upstream data are sent to base station in multiplexing mode by the 2nd PUSCH.And base station presets and will detect UCI from a PUSCH, so just caused base station to detect error in data.

For fear of above-mentioned situation, produce, UE can carry UCI indication information in carrying the PUSCH of UCI.This UCI indication information is used for showing whether this PUSCH carries UCI.

This UCI indication information can implicitly carry.For example, can adopt CRC scrambling mode, malice adopts the CCE label of PDCCH in search volume, can adopt the label of Resource Block of the PUSCH of PDCCH scheduling.Concrete grammar can be:

(1) can in PDCCH, increase a bit, for representing whether the current PUSCH being scheduled carries UCI.For example, this newly-increased bit is set to 1, represents to carry UCI in the current PUSCH being scheduled, and this newly-increased bit is set to 0, represents not carry UCI in the current PUSCH being scheduled.

(2) a UL_grant signaling format 0 ' can be set, combine differentiation with existing UL_grant form 0 and DL_grant form 1A.For example, Head Section proportion by subtraction is specially for 0 presentation format 0, and Head Section proportion by subtraction is specially for 10 presentation format 1A, and Head Section proportion by subtraction is specially for 11 presentation formats 0 '.Now can represent to carry UCI in the current PUSCH being scheduled with UL_grant form 0 ', with UL_grant form 0, represent not carry UCI in the current PUSCH being scheduled; Or vice versa.

(3) can implicitly carry in the current PUSCH being scheduled and carry UCI whether information with PDCCH, for example, can adopt the mode of CRC scrambling to represent whether carry UCI in the current PUSCH being scheduled.Concrete, with scrambler 1, come the CRC of scrambling PDCCH to represent to carry UCI in the current PUSCH being scheduled, with scrambler 2, come the CRC of scrambling PDCCH to represent not carry UCI in the current PUSCH being scheduled, vice versa; Can adopt the CCE label of PDCCH in search volume to represent whether carry UCI in the current PUSCH being scheduled.Concrete, the PDCCH that takies the initial CCE label of odd number in search volume represents to carry UCI in the current PUSCH being scheduled, and the PDCCH that takies the initial CCE label of even number in search volume represents not carry UCI in the current PUSCH being scheduled, and vice versa; Can adopt the label of Resource Block of the PUSCH of PDCCH scheduling to represent whether carry UCI in the current PUSCH being scheduled.Concrete, the initial Physical Resource Block of odd number that the PUSCH of scheduling takies represents to carry UCI in the current PUSCH being scheduled, and the initial Physical Resource Block of even number that the PUSCH of scheduling takies represents not carry UCI. in the current PUSCH being scheduled.

(4) can trigger bit with CSI aperiodic in UL_grant form 0 and indicate in the current PUSCH being scheduled whether carry UCI.Specifically be divided into two scenes as follows:

When not being the moment that periodically CSI need to feed back, CSI aperiodic in UL_grant form 0 triggers bit can be as normal CSI triggering aperiodic; When to the moment that periodically CSI need to feed back, CSI aperiodic in UL_grant form 0 triggers bit and is just not used as CSI triggering aperiodic, and as whether carrying UCI in the current PUSCH being scheduled of indication, for example be set in the current PUSCH being scheduled of 0 expression and carry UCI, be set in the current PUSCH being scheduled of 1 expression and do not carry UCI, vice versa.

(4b) scene: aperiodic and cycle, CSI can occur simultaneously.

With CSI aperiodic in UL_grant form 0, trigger bit and indicate in the current PUSCH being scheduled whether carry UCI. for example, this triggering bit is set in the current PUSCH being scheduled of 0 expression and carries UCI, be set in the current PUSCH being scheduled of 1 expression and do not carry UCI, vice versa.

Or, also can adopt following method to avoid the generation of above-mentioned situation.

When the uplink transmission mode of UE is single antenna mouth, base station can be cyclic shift CS1 and the CS2 of reserved two the uplink demodulation pilot tones of each UE, or be reserved two the ascending pilot frequency time domain spreading code OC1 of each UE and OC2, wherein reservation mode can be notified for explicit signaling, for example can pass through PDCCH signaling, also can notify by other high-level signalings.Or, can notify for implicit expression, the CS1 that for example UE can notify based on existing eNB, calculates another CS2 according to certain relation, and physical relationship can be CS2=CS1+i, and the value of i can arrange according to actual needs.

When UE sends CS1 or OC1, represent not carry UCI in this PUSCH, when UE sends CS2 or OC2, represent to carry UCI in this PUSCH.

Blind Detecting, before detecting data, is first carried out to two CS or OC in base station, and which CS that determine UE transmission is, which OC, thus determine on this PUSCH whether carry UCI, and correspondingly according to definite result, detect the upstream data on PUSCH.

When the uplink transmission mode of UE is many antennas, cyclic shift CS1 and the CS2 of two uplink demodulation pilot tones can be reserved at least one antenna opening of each UE in base station.Wherein, reservation mode can be notified to UE by explicit signaling, for example, can pass through PDCCH signaling, or other high-level signaling is notified to UE.Or, can notify for implicit expression, the CS1 that for example UE can notify based on existing eNB, calculates another CS2 according to certain relation, and physical relationship can be CS2=CS1+i, and the value of i can arrange according to actual needs.

When UE sends CS1, represent not carry UCI in this PUSCH, when UE sends CS2, represent to carry UCI in this PUSCH.

When the uplink transmission mode of UE is many antennas, also can whether represent in PUSCH with UCI by OC1 and OC2.
