Description

The transmission method of ACK/NACK, method of reseptance and device thereof
Technical field
The present invention relates to wireless communication field, particularly relate to the transmission method of a kind of ACK/NACK, method of reseptance and dress thereof Put.
Background technology
For LTE-A(Long Term Evolution Advanced, long-term evolution upgrading) multicarrier system, for supporting Ratio LTE(Long Term Evolution, Long Term Evolution) the broader system bandwidth of system, such as 100MHz, one is probably directly Connect the frequency spectrum of distribution 100M bandwidth, single-frequency spectral system schematic as shown in Figure 1；Alternatively possible is to use CA(Carrier Aggregation, carrier aggregation) technology, some spectrum aggregatings of existing system will be distributed to, constitute the supply of big bandwidth long Phase evolution multicarrier system uses, and now in system, up-downgoing carrier wave can be with asymmetric arrangement, i.e. user may take N1 >=1 Individual carrier wave carries out downlink transfer, and N2 >=1 carrier wave carries out uplink, frequency spectrum polymerization system schematic diagram as shown in Figure 2.
Lte-a system determines at present at most can support that 5 carrier waves are polymerized, the UE(User Equipment of LTE-A, Subscriber equipment) need at the same multiple descending carrier of sub-frame of uplink internal feedback and the ACK of descending sub frame (Acknowledgment, positive acknowledgment)/NACK(Negative Acknowledgment, Negative Acknowledgement) feedback information.
On each descending carrier, corresponding same sub-frame of uplink carries out the descending sub frame of ACK/NACK feedback as shown in table 1, M Carry out the descending sub frame number of ACK/NACK feedback for a sub-frame of uplink corresponding on each descending carrier, M is to different up sons Frame and different TDD(Time Division Duplexing, time division duplex) uplink-downlink configuration value difference, it is shown in table 1 Descending sub frame set corresponding to each sub-frame of uplinkIn descending sub frame sum.Particularly, for Uplink-downlink configuration 0 and 5 is at conventional CP(Cyclic Prefix, Cyclic Prefix) under, and uplink-downlink configuration 0 and 4 is under extension CP Special descending sub frame, can not count, i.e. M may not include this subframe, and UE is not to this subframe feeding back ACK/NACK.
Table 1 Downlink association set index: for TDD
Lte-a system supports that ACK/NACK is at PUSCH(Physical Uplink Shared Channel, physical uplink Share channel) upper transmission, for there is no corresponding PDCCH(Physical Downlink Control Channel, physical down Control channel) SPS(Semi-persistent Scheduling, semi-continuous scheduling) PUSCH, owing to PUSCH is without corresponding UL grant(uplink scheduling is permitted), therefore UE cannot be according to the UL DAI(Downlink Assignment in UL grant Index, descending distribution indexes) (includeOr) determine the ACK/NACK feedback information of each descending carrier.For this The situation of kind, regulation UE transmission ACK/NACK on PUSCH as follows in existing standard:
(1) if UE is in the current sub-frame of uplink of correspondence carries out the descending sub frame of multiple descending carriers of ACK/NACK feedback Receive at least one PDSCH(Physical Downlink Shared Channel, Physical Downlink Shared Channel) or instruction Descending SPS resource release PDCCH, then UE according to following manner determine PUSCH on transmit ACK/NACK feedback information:
A, when ACK/NACK be configured use PUCCH (Physical Uplink Control Channel, physical uplink Control channel) format(form) 3 time, UE is to single codeword transmission mode or the many code words transmission mode carrying out space merging Each descending carrier produces M-bit ACK/NACK feedback information；To being not received by PDSCH or the release of indicating downlink SPS resource PDCCH descending carrier on descending sub frame produce 1 bit NACK as feedback information；To many code words transmission mode and do not enter Each descending carrier that row space merges produces 2M bit ACK/NACK feedback information；To being not received by under PDSCH or instruction Descending sub frame on the descending carrier of the PDCCH of row SPS resource release produces 2 bit NACK as feedback information, under each The ACK/NACK feedback information of row carrier wave cascades up and transmits on PUSCH, and wherein N is the descending carrier number of UE configuration/polymerization, M is the corresponding descending sub frame number carrying out ACK/NACK feedback at a sub-frame of uplink on each up-link carrier.
B, it is configured to use PUCCH format 1b with channel selection and being polymerized as ACK/NACK During 2 descending carriers, UE most transmission 4 bit informations on PUSCH:
As M=1, UE does not carry out space merging to the ACK/NACK feedback information of many code words, on each descending carrier The PDCCH of each code word or the release of indicating downlink SPS resource produces the ACK/NACK feedback information of 1 bit；To being not received by Each code word on the descending carrier of the PDCCH of PDSCH or the release of indicating downlink SPS resource or the release of indicating downlink SPS resource PDCCH produce NACK as feedback information, the ACK/NACK feedback information of each descending carrier is cascaded up on PUSCH Transmission；
As M=2, UE carries out space merging to the ACK/NACK feedback information of many code words, every on each descending carrier Individual subframe produces the ACK/NACK feedback information of 1 bit；To be not received by PDSCH or indicating downlink SPS resource release The ACK/NACK of each descending carrier, as feedback information, is fed back by the descending sub frame generation NACK on the descending carrier of PDCCH Information cascades up and transmits on PUSCH；
As M=3 or 4, UE carries out space merging, each descending carrier correspondence 2 to the ACK/NACK feedback information of many code words Bit information represents on descending carrier that first descending sub frame starts continuous print ACK number, wherein 4 ACK can with 1 ACK or Other ACK numbers share a feedback states of 2 bit informations, are cascaded up by 2 corresponding for each descending carrier bit informations PUSCH transmits；
(2) if UE carries out all descending son of multiple descending carriers of ACK/NACK feedback at the current sub-frame of uplink of correspondence All be not received by PDSCH or the PDCCH of indicating downlink SPS resource release in frame, then UE does not transmit ACK/NACK on PUSCH Feedback information.
Map, in the four of pilot tone both sides by carrying out upstream data punching on PUSCH in view of ACK/NACK After row symbols elder generation time domain, frequency domain is placed from low to high, and ascending control information as shown in Figure 3 is in PUSCH ascending physical signal resource Mapping schematic diagram, UE above-mentioned transmits the mode of ACK/NACK on PUSCH, and there are the following problems:
If base station exists PDSCH in the current sub-frame of uplink of correspondence carries out the descending sub frame of ACK/NACK feedback, scheduling passes Defeated or the release of indicating downlink SPS resource PDCCH transmits, it is contemplated that UE there may be loss PDSCH or indicating downlink SPS resource The situation of the PDCCH of release, base station and UE may be inconsistent to the understanding whether transmitting ACK/NACK on PUSCH.Therefore, base Station needs to carry out SPS PUSCH the DTX(Discontinuous Transmission of ACK/NACK feedback information, discontinuously Send) detection, to judge whether UE transmits ACK/NACK feedback information.
But, there is certain error probability in the DTX of ACK/NACK feedback information；If UE have sent this on PUSCH ACK/NACK, but base station is to when on PUSCH, the DTX testing result of ACK/NACK is DTX, and base station thinks that UE is not on PUSCH Send ACK/NACK, then base station lost the ACK/NACK information of UE feedback, will result in descending redundant retransmission, and by ACK/NACK Information is decoded as upstream data, thus affects being properly received of upstream data；If UE does not send out this on PUSCH Sending ACK/NACK, but base station is to when the DTX testing result of ACK/NACK is non-DTX on PUSCH, base station thinks that UE is on PUSCH Have sent ACK/NACK, then upstream data is decoded by base station as ACK/NACK information, has obtained the ACK/NACK of mistake Feedback information, will result in descending redundant retransmission or erroneous transmissions, also affects being properly received of upstream data simultaneously.
It addition, the resource that ACK/NACK transmits on PUSCH is according to different ACK/NACK feedback bits length and in advance The resource offset parameter of the ACK/NACK relative uplink data of configurationDetermine.Resource offset i.e. ACK/ RE(Resource Element shared by NACK feedback information, Resource Unit) number is relative to the upstream data on PUSCH The adjustment amount of shared RE number, to ensure the transmission reliability of the ACK/NACK under different upstream data MCS grade.
Owing to ACK/NACK is different, when PUSCH multi-code with many code words (2 code words) the upper transmission means of PUSCH in single codeword During word transmission, ACK/NACK is mapped in every layer and repeats transmission, and ACK/NACK is in single codeword transmission and many codeword transmission PUSCH Transmission performance is different, in order to avoid the wasting of resources, the PUSCH of single codeword and many codeword transmission is defined calculating respectively,It is pre-configured with for high-level signaling, i.e. based on the bandwidth of PUSCH transmission in a period of time With MCS(modulation and coding style, modulation coding mode) grade isoparametric change demand and set.
Transmission bandwidth and MCS grade for SPS PUSCH, PUSCH were fixed, therefore, based on dynamically within a period of time The bandwidth of the PUSCH transmission of change and MCS grade determineIt is no longer desirable for the ACK/ on SPS PUSCH NACK transmits.
Additionally, for TDD system uplink-downlink configuration 0 or FDD system, owing to UL grant not existing 2 bit UL DAI, Therefore, when ACK/NACK transmits on PUSCH, there are the problems referred to above too.
During realizing the present invention, inventor finds at least to there is problems in that in prior art
In LTE-A CA system, for there is no the SPS PUSCH of corresponding PDCCH, or under TDD uplink-downlink configuration 0 PUSCH in PUSCH, or FDD system, if UE carries out all descending son of ACK/NACK feedback at the current sub-frame of uplink of correspondence All be not received by PDSCH or the PDCCH of indicating downlink SPS resource release in frame, then UE will not transmit ACK/ on PUSCH NACK feedback information.When UE downlink data is lost, will result in base station and the UE understanding to whether transmitting ACK/NACK on PUSCH Inconsistent, thus affect the detection performance of ACK/NACK and upstream data.

Detailed description of the invention
In LTE-A CA system, UE cannot be according to the UL DAI in UL grantOrDetermine each descending The ACK/NACK feedback information of carrier wave, if UE carries out all descending sub frames of ACK/NACK feedback at the current sub-frame of uplink of correspondence In be all not received by PDSCH or the PDCCH of indicating downlink SPS resource release, then not transmit ACK/NACK on PUSCH anti-for UE Feedforward information；Base station is to needing SPS PUSCH to carry out ACK/NACK DTX detection, to judge whether UE transmits ACK/NACK feedback letter Breath.If the ACK/NACK DTX detection of base station makes mistakes, then can affect base station to upstream data and the solution of ACK/NACK feedback information Tonality energy.
For the problems referred to above, the embodiment of the present invention proposes a kind of ACK/NACK feedback information transmission method at PUSCH, To avoid base station and UE to understand differently cause to whether transmitting ACK/NACK on PUSCH, and then avoid base station to ACK/ on PUSCH The DTX detection of NACK feedback information, improves upstream data and the transmission reliability of ACK/NACK feedback information.
Below in conjunction with the accompanying drawings the embodiment of the present invention is described in detail.
Embodiment one
The embodiment of the present invention provides the transmission method of a kind of ACK/NACK, and as shown in Figure 4, the method comprises the following steps:
Step 401, UE determines the ACK/NACK feedback information of transmission on PUSCH.
In the embodiment of the present invention, in lte-a system, when ACK/NACK feedback information is in PUSCH transmission, if UE is true The fixed PUSCH for transmitting uplink control information is the PUSCH of the PDCCH not having correspondence or joins for up-downgoing in TDD system PUSCH under setting to 0 or during for PUSCH in FDD system, no matter UE current sub-frame of uplink corresponding need carry out ACK/ Whether the descending sub frame of NACK feedback receives the PDCCH, UE of PDSCH or the release of indicating downlink SPS resource all on PUSCH Transmission ACK/NACK feedback information is (if the sub-frame of uplink that i.e. UE sends PUSCH in correspondence carries out the descending of ACK/NACK feedback The PDCCH, UE that are not received by PDSCH or the release of indicating downlink SPS resource in subframe are also required on PUSCH transmit ACK/ NACK feedback information).
Specifically, i.e. for not having UL DAI(to include but not limited toOr) PUSCH of information, no matter UE Current sub-frame of uplink corresponding need carry out whether all descending sub frames of all descending carriers of ACK/NACK feedback connect The PDCCH, UE that receive PDSCH or the release of indicating downlink SPS resource all transmit ACK/NACK feedback information on these PUSCH.
In the embodiment of the present invention, UE determines that the mode of the ACK/NACK feedback information of transmission includes on PUSCH:
Mode one: UE is according to current sub-frame of uplink corresponding on the descending carrier number N self configured and each descending carrier Carry out the descending sub frame number M of ACK/NACK feedback, determine that UE needs the ACK/NACK number of bits of feedback of transmission on PUSCH and anti- Feedforward information sequence.
(1) for each descending carrier, when this descending carrier is single codeword transmission mode or many code words transmission mode and adopts When merging with space, UE needs to produce this descending carrier the ACK/NACK feedback information of M-bit；When this descending carrier is multi-code Word transmission mode and when not using space to merge, UE needs to produce this descending carrier the ACK/NACK feedback information of 2M bit. Wherein M is the descending sub frame number that corresponding current sub-frame of uplink carries out ACK/NACK feedback.
(2) descending sub frame of the UE PDCCH to being not received by PDSCH or the release of indicating downlink SPS resource produces NACK As ACK/NACK feedback information；Wherein, for each descending carrier, when this descending carrier is single codeword transmission mode or many When codeword transmission pattern and employing space merge, UE produces 1 bit NACK to descending sub frame；When this descending carrier is that many code words pass Defeated pattern and when not using space to merge, UE produces 2 bit NACK to descending sub frame.
For above-mentioned two situations, when UE transmits ACK/NACK feedback information on PUSCH, this UE is by each descending carrier Corresponding ACK/NACK feedback information is concatenated together, and is transmitted on PUSCH.
Mode two: UE according to the PUCCH transformat of the transmission ACK/NACK feedback information being currently configured or using and/ Or ACK/NACK merges mode, determine ACK/NACK number of bits of feedback and the feedback information sequence of transmission on PUSCH；I.e. UE root Merge the difference of mode according to PUCCH transformat and ACK/NACK, use distinct methods to determine the ACK/NACK of transmission on PUSCH Feedback information bits number and feedback information sequence.
(1) the PUCCH transformat that UE is currently configured or uses is that the PUCCH i.e. UE of format 3(uses on PUCCH PUCCH format 3 format transmission ACK/NACK feedback information) time, UE determines the ACK/NACK feedback letter of transmission on PUSCH The mode of breath includes:
For each descending carrier, when this descending carrier is single codeword transmission mode or many code words transmission mode and employing When space merges, UE needs to produce this descending carrier the ACK/NACK feedback information of M-bit；When this descending carrier is many code words Transmission mode and when not using space to merge, UE needs to produce this descending carrier the ACK/NACK feedback information of 2M bit.Its Middle M is the descending sub frame number that corresponding current sub-frame of uplink carries out ACK/NACK feedback.
The descending sub frame of the UE PDCCH to being not received by PDSCH or the release of indicating downlink SPS resource produces NACK conduct ACK/NACK feedback information；Wherein, for each descending carrier, when this descending carrier is single codeword transmission mode or many code words When transmission mode and employing space merge, UE produces 1 bit NACK to descending sub frame；When this descending carrier is many codeword transmission mould Formula and when not using space to merge, UE produces 2 bit NACK to descending sub frame.
When UE transmits ACK/NACK feedback information on PUSCH, this UE is by anti-for ACK/NACK corresponding for each descending carrier Feedforward information is concatenated together, and is transmitted on PUSCH.
(2) the PUCCH transformat that UE is currently configured or uses is PUCCH format 1b with channel Selection(i.e. UE uses PUCCH format 1b with channel selection format transmission ACK/ on PUCCH NACK feedback information) time, UE determines that the mode of the ACK/NACK feedback information of transmission includes on PUSCH:
As M=1, UE does not carry out space merging to the ACK/NACK feedback information of many code words；To on each descending carrier The PDCCH of each code word or the release of indicating downlink SPS resource produces the ACK/NACK feedback information of 1 bit, i.e. to each descending Carrier wave produces this descending carrier of M(when being single codeword transmission) or time this descending carrier of 2M(is many codeword transmission) bit ACK/NACK Feedback information；Wherein, UE to be not received by PDSCH or indicating downlink SPS resource release PDCCH descending carrier on every The PDCCH of individual code word or the release of indicating downlink SPS resource produces NACK as ACK/NACK feedback information；By each descending load The ACK/NACK feedback information of ripple cascades up and transmits on PUSCH.
As M=2, UE carries out space merging to the ACK/NACK feedback information of many code words；Every on each descending carrier Individual descending sub frame produces the ACK/NACK feedback information of 1 bit, i.e. raw to each descending carrier common property M-bit ACK/NACK feedback Information；Wherein, the descending son on the descending carrier of the UE PDCCH to being not received by PDSCH or the release of indicating downlink SPS resource Frame produces NACK as ACK/NACK feedback information；The ACK/NACK feedback information of each descending carrier is cascaded up The upper transmission of PUSCH.
As M=3 or 4, UE produces, to each descending carrier, the ACK/NACK feedback information that Z bit merges, and this Z bit is believed Breath represents that on this descending carrier, first descending sub frame starts continuous print ACK number, the descending sub frame number being properly received the most continuously.
Wherein, M is the descending sub frame number that corresponding current sub-frame of uplink carries out ACK/NACK feedback.
Such as, each descending carrier is produced the ACK/NACK feedback information of Z=2 bit merging (first to many code words ACK/NACK carries out space merging), wherein 4 ACK can share of 2 bit informations with 1 ACK or other ACK numbers 2 corresponding for each descending carrier bit informations are cascaded up and transmit on PUSCH by feedback states；As shown in table 2, for The merging feedback bits of each carrier wave that channel selection time domain merges.
Table 2
(3) ACK/NACK merges mode and includes that time domain ACK/NACK merges mode, and this time domain ACK/NACK merges mode and is: M descending sub frame on each carrier wave is divided into L(1≤L≤M) individual descending sub frame group, Ti(1≤Ti in each descending sub frame group ≤ M, 1≤i≤L) individual subframe, to corresponding same code in the multiple descending sub frames in descending sub frame group each on same descending carrier The ACK/NACK feedback information of sub-position merges.When UE uses above-mentioned time domain ACK/NACK to merge mode on PUCCH, Descending sub frame packet count L that UE merges according to time domain on each descending carrier used on PUCCH, every group on each descending carrier A bit ACK/NACK feedback information after the merging that descending sub frame is corresponding and the descending carrier number N of UE polymerization/activation, determine The ACK/NACK feedback information bits number transmitted on PUSCH and feedback information sequence.
Further, above-mentioned time domain ACK/NACK is used to close the ACK/NACK feedback information on each descending carrier as UE And during mode, UE can obtain A bit ACK/NACK feedback information that each descending sub frame group on each descending carrier is corresponding, will be many A bit ACK/NACK feedback information after the merging that on individual descending carrier, each descending sub frame group is corresponding is concatenated together, and obtains A × L × N-bit ACK/NACK feedback information, transmits on PUSCH.
In the embodiment of the present invention,, when M descending sub frame on each descending carrier is divided into L group, often The descending sub frame number Ti that group comprises can be identical, it is also possible to different；Descending sub frame packet mode on different descending carriers is permissible Identical, it is also possible to different；Preferably, the descending sub frame packet mode on each descending carrier is that T=M, L=1, i.e. UE are by under one All M descending sub frames on row carrier wave are divided into one group to carry out time domain merging, and finally give A × N-bit ACK/NACK feedback Information is transmitted on PUSCH.
Additionally, carry out the descending sub frame group of space merging for single codeword transmission or many code words ACK/NACK feedback information, ACK/NACK number of bits of feedback A=1 after the merging of its correspondence；For many codeword transmission and many code words ACK/NACK feedback information Do not carry out the descending sub frame group of space merging, ACK/NACK number of bits of feedback A=2 after the merging of its correspondence；M be UE current on The maximum of the corresponding descending sub frame number carrying out ACK/NACK feedback on row subframe row carrier wave in each of the lower.
For above-mentioned situation, time domain as shown in Figure 5 merges the time domain shown in schematic diagram and Fig. 6 and merges schematic diagram, figure 5 and Fig. 6 merging modes giving two kinds of descending sub frame packets, in Fig. 5, T=4, L=1；In Fig. 6, T1=2, T2=1, L=2.
(4) ACK/NACK merges mode and includes that frequency domain ACK/NACK merges mode, and this frequency domain ACK/NACK merges mode and is: N number of descending carrier that UE configures is divided into K(1≤K≤N) individual downstream carrier group, Pi(1≤Pi≤N in each downstream carrier group, 1 ≤ i≤K) individual carrier wave, the ACK/NACK feedback corresponding to same descending sub frame on descending carriers multiple in same downstream carrier group Information merges.When UE uses above-mentioned frequency domain ACK/NACK to merge mode on PUCCH, UE is according to employing on PUCCH B bit ACK/NACK feedback letter after descending carrier packet count K that frequency domain merges and often group merging corresponding to descending carrier Breath, determines ACK/NACK feedback information bits number and the feedback information sequence of transmission on PUSCH.
Further, as UE, the ACK/NACK often organizing same subframe position on multiple descending carriers in descending carrier is fed back When information uses above-mentioned frequency domain ACK/NACK to merge mode, UE can obtain the B ratio after the merging of correspondence to each downstream carrier group Special ACK/NACK feedback information, the B bit ACK/NACK feedback information after often organizing the merging of descending carrier is concatenated together, To B × K bit ACK/NACK feedback information, PUSCH transmits.
