Description

A kind of ACK/NACK feedback sequences determine method and apparatus

Technical field

The present invention relates to communication technical field, more particularly to a kind of ACK/NACK feedback sequences determine method And device.

Background technology

Long Term Evolution strengthen (LTE-A, Long Term Evolution-Advanced) version (Rel, Release) in -10 carrier aggregations (CA, Carrier Aggregation) system, most 5 carrier waves are supported Polymerization.PUCCH format3 are defined, most 22 bit information transmission can be carried.In LTE-A Rel-13 In CA systems, most 32 carrier aggregations are supported.With the increase of polymerization number of carrier wave, terminal feedback affirmative Ack/nack (ACK/NACK, ACKnowledgement/Non-ACKnowledgement) is anti- The quantity of feedforward information also will substantially increase.The physical uplink of transmission ACK/NACK defined in earlier version Control channel (PUCCH, Physical Uplink Control Channel) form (format) can not Support the so many ACK/NACK feedback bits of transmission, it is therefore desirable to define bigger new of capacity PUCCH format 4 and 5, its data and pilot configuration are as shown in figure 1, wherein Di represents a symbol Sequence.PUCCH format 4 in orthogonal sequence, therefore 1 PRB without using can only transmit 1 end End, PUCCH format 5 in order to further improve multiplexing capacity, frequency domain used length for 2 it is orthogonal Frequency expansion sequence, therefore its bearer cap is PUCCH format 4 half.PUCCH format 4 and 5 All use QPSK/QPSK (QPSK, Quadrature Phase-Shift Keying) Modulation system.PUCCH format 4 can use more than one Physical Resource Block (PRB, Physical Resource Block) transmission, assuming that only taking up 1 PRB and conventional cyclic prefix (CP, Cyclic When Prefix), PUCCH format 4 can carry the modulation of the information after 288 bits of encoded, i.e., 144 Symbol, PUCCH format 5 can carry the modulation symbol of the information after 144 bits of encoded, i.e., 72.

For FDD (FDD, Frequency Division Duplex), the descending biography in its subframe n Defeated ACK/NACK feedback informations feed back in subframe n+4, then feedback window can be defined as terminal gather The descending carrier set of conjunction.For time division duplex (TDD, Time Division Duplex), due to difference TDD uplink-downlink configurations corresponding to ascending-descending subframes number it is different, therefore for different above and below TDD Row configuration respectively defines ACK/NACK feedback sequential, as shown in table 1, on same carrier wave not ACK/NACK feedback informations with descending sub frame may need to be transmitted in same sub-frame of uplink, The set K according to corresponding to numbering is n sub-frame of uplink：{k₀,k₁,…k_M-1In each element k values, can be with It is determined that (i.e. numbering is n-k to the descending sub frame of needs progress ACK/NACK feedbacks in sub-frame of uplink n Descending sub frame, including special subframe), then same sub-frame of uplink needs to feed back most M descending sons The ACK/NACK feedback informations of frame, M is the element number in set K, to different sub-frame of uplink It is not necessarily identical with different TDD uplink-downlink configurations M value；When terminal polymerize multiple TDD carrier waves When, the descending sub frame determined according to above-mentioned feedback sequential on multiple carrier waves is also required to simultaneously in sub-frame of uplink n Middle feedback, therefore TDD feedback window is M subframe in time domain, N number of configuration carrier wave on frequency domain.

Table 1：The descending sub frame of the progress ACK/NACK feedbacks in same sub-frame of uplink is needed in TDD Index set K:{k₀,k₁,…k_M-1}(Downlink association set index K:{k₀,k₁,…k_M-1}for TDD)

Wherein, the numbering in table 1 is the subframe that numbering is n-k in units of radio frames, if n-k Less than 0, then the subframe in previous radio frames is shown to be.

In order to ensure terminal with base station to ACK/NACK feedback sequences (ACK/NACK codebook) Understand consistent, determined defined in Rel-12 and foregoing version according to the size of feedback window ACK/NACK codebook, i.e., need to produce ACK/NACK feedbacks to all configuration carrier waves to FDD Information, for TDD, it is necessary to produce ACK/NACK feedbacks to M subframe and N number of configuration carrier wave Information, wherein, NACK occupy-places are produced to the subframe/carrier wave for not receiving data.When terminal polymerization exceedes During 5 carrier waves, when particularly polymerization carrier number is larger, the ACK/NACK codebook that this mode is determined It is larger, wherein more garbage is contained, so as to reduce the transmission of ACK/NACK feedback informations Efficiency.

Even if having polymerize 32 carrier waves in view of terminal, also not always in all carrier waves and M subframe all Schedule data transmission, in order to improve the efficiency of transmission of ACK/NACK feedback informations, defines dynamic ACK/NACK codebook transmission means, according to the Physical Downlink Control Channel received in feedback window (PDCCH, Physical Downlink Control Channel)/enhanced Physical Downlink Control Channel Descending distribution index (the Counter for stored count in (EPDCCH, Enhance PDCCH) DAI, abbreviation C-DAI；Downlink Assignment Index, abbreviation DAI) and it is total for indicating The DAI (Total DAI, abbreviation T-DAI) of scheduling data volume is determined corresponding to the feedback window ACK/NACK codebook；ACK/NACK feedback informations are ranked up by C-DAI, passed through T-DAI determines the bit number of ACK/NACK feedback informations, can always be less than or equal to according to feedback window Size determine ACK/NACK codebook, as shown in Figure 2 A and 2 B, Fig. 2A represents FDD In DAI structures, Fig. 2 B represent the DAI structures in TDD.Wherein, C-DAI and T-DAI are 2 bits, indicating mode is as shown in table 2 for FDD, as shown in table 3 for TDD.

Table 2:C-DAI and T-DAI value (Value of counter DAI and total DAI)

Table 3:C-DAI and T-DAI value (Value of counter DAI and total DAI)

Identical 2 is multiplexed by way of mould 4 when the numerical value expressed by C-DAI and T-DAI is more than 4 Bit DAI state indicated, assume in systems the probability for continuously losing 4 packets it is micro- its Micro-, therefore, which in multiple numerical value what UE can judge now to indicate according to the DAI values received is Individual value, such as UE receives C-DAI=1 and T-DAI=1, and UE is received before the packet To 4 packets, then it is assumed that the numerical value that now C-DAI and T-DAI is indicated is 5.

Using dynamic ACK/NACK codebook (dynamic ACK/NACK codebook) at present When, C-DAI and value indicated by T-DAI are all only for having corresponding PDCCH/EPDCCH's PDSCH and the release of indicating downlink semi-continuous scheduling (SPS, Semi-Persistent Scheduling) resource PDCCH/EPDCCH quantity count；And SPS business can also be configured in main member carrier, Activate PDCCH/EPDCCH to trigger a SPS PDSCH transmission by SPS, the SPS is not having Have before receiving the PDCCH/EPDCCH for indicating the release of SPS resources, all according to the cycle being pre-configured with, The periodic transfer in SPS subframes, if there is the PDSCH of dynamic dispatching, i.e. base station in the SPS subframes A PDSCH with corresponding PDCCH/EPDCCH is have sent in the SPS subframes, then the SPS PDSCH data message will be bundled in the dynamic PDSCH and transmit；Therefore, if wrapped in feedback window SPS subframes are contained, as shown in figure 3, have received C-DAI=2 in carrier wave (CC) 3 for FDD, UE PDCCH/EPDCCH, so as to judge to exist before carrier wave 31 carrier wave packet loss, but user Equipment (UE) can not judge the packet loss of carrier wave 1 or the packet loss of carrier wave 2, situation 1：UE thinks carrier wave 1 Packet loss, then on carrier wave 2 without transmission, then UE thinks that now SPS PDSCH are packaged into dynamic PDSCH There is no SPS PDSCH ACK/NACK feedback informations, therefore root in middle transmission, i.e. this feedback window Need to produce 6 bit ACKs/NACK feedback informations according to T-DAI instruction；Situation 2：UE thinks carrier wave 2 packet losses, and SPS PDSCH are received according to SPS resources on carrier 1, obtain SPS PDSCH's ACK/NACK feedback informations, i.e. UE judge that the feedback window has SPS PDSCH ACK/NACK Feedback information, then also need to add 1 bit on the basis of 6 bit informations determined according to T-DAI instruction SPS PDSCH feedback information, that is, feed back 7 bit ACKs/NACK feedback informations.Above-mentioned two situations Under, UE ACK/NACK number of bits of feedback is different, and if the actual schedule transmission of base station is with UE's Understand differently cause, and for example base station actually have sent dynamic PDSCH in carrier wave 1, i.e., beat SPS PDSCH Wrap and transmitted in dynamic PDSCH, and UE is interpreted as situation 2, or base station is actually sent in carrier wave 1 SPS PDSCH and in carrier wave 2 dynamic PDSCH is have sent, and UE is interpreted as situation 1, can all lead The cause that understands differently of base station and UE to ACK/NACK number of bits of feedback is caused, so as to cause base station mistake ACK/NACK is received.TDD situations shown in Fig. 4 are similarly.At present for the problem also without clear and definite Solution.

In summary, if terminal is configured with SPS business, existing dynamic ACK/NACK codebook are carried out During the feedback of ACK/NACK feedback informations, may there are base station and UE to ACK/NACK Codebook understands differently cause, so as to cause the ACK/NACK of base station mistake to receive.

In the embodiment of the present invention, it is determined that being configured with semi-continuous scheduling SPS business and/or needing in up son When there is SPS subframes in the sub-frame set that ACK/NACK feedbacks are carried out in frame n, by described first ACK/NACK number of bits of feedback is defined as the 2nd ACK/NACK feedback bits with setting bit number sum Number, and ACK/NACK feedback sequences are received according to the 2nd ACK/NACK number of bits of feedback, by In receiving ACK/NACK feedback sequences using the 2nd ACK/NACK number of bits of feedback, so as to avoid Understand differently cause of the during terminal packet loss and base station to ACK/NACK codebook.

In the embodiment of the present invention, above-mentioned steps S51~S52 executive agent is network side equipment, such as base station.

Wherein, the setting bit number, the DAI and the Physical Downlink Control Channel refer to Fig. 5 Associated description in shown embodiment, here is omitted.

In force, the subframe for needing to carry out ACK/NACK feedbacks in sub-frame of uplink n is determined in S62 There is SPS subframes in set, including：

And/or

Based on any of the above-described embodiment, received in S62 according to the 2nd ACK/NACK number of bits of feedback After ACK/NACK feedback sequences, in addition to：

If have sent the Physical Downlink Shared Channel without corresponding Physical Downlink Control Channel, it is determined that described The feedback information for setting bit number on setting position in ACK/NACK feedback sequences is described no pair The ACK/NACK feedback informations of the Physical Downlink Shared Channel for the Physical Downlink Control Channel answered；

Or

Optionally, the setting position in the ACK/NACK feedback sequences is：With described first The front or behind of the first corresponding ACK/NACK feedback sequences of ACK/NACK number of bits of feedback.

Below by two specific embodiments, a kind of ACK/NACK provided in an embodiment of the present invention is fed back Sequence determines that method is described in detail.

Embodiment 1：As shown in Figure 3, it is assumed that the transmission mode of each carrier wave is 1TB, i.e., each carrier wave If necessary to ACK/NACK feedbacks, then 1 bit ACK/NACK is corresponded to；Assuming that carrier wave 1 is main member Carrier wave, and present sub-frame i is SPS subframes：

End side have received downlink transfer according to reality on 4 carrier waves, and finally receive C-DAI=1 and T-DAI=2, judge T-DAI indicate for 6, that is, have 6 carrier waves there are it is corresponding Carrier wave and/or indicating downlink SPS the resources release of the Physical Downlink Shared Channel of Physical Downlink Control Channel Physical downlink control channel transmission, i.e., be 6 according to DAI the first ACK/NACK number of bits of feedback determined Bit；

Due to there is SPS subframes in feedback window, then terminal determines actual ACK/NACK feedback bits Number O^ACK=6+1=7 bits；

The ACK/NACK of the downlink transfer received is mapped to 6 bits by terminal according to C-DAI orders Relevant position in one ACK/NACK feedback sequences, and the position for being not received by downlink transfer is produced NACK, obtains the ACK/NACK feedback sequences of 6 bit the first NACK,o_cc3,o_cc4,o_cc5,o_cc7, NACK, wherein, o_cciFor the ACK/NACK feedback ratios of correspondence carrier wave It is special；

Terminal judges carrier wave 3 according to the C-DAI=2 in the Physical Downlink Control Channel that carrier wave 3 is received There is a carrier wave packet loss before, specifically include situations below：

Situation 1：Transmitted assuming that judging that the packet loss of carrier wave 1, i.e. SPS PDSCH are packaged in dynamic PDSCH, Without SPS PDSCH in feedback window, terminal produces 1 bit NACK, is mapped in the first ACK/NACK After feedback sequence, i.e. last position in the final ACK/NACK feedback sequences of 7 bits is obtained To 7 final bit ACKs/NACK feedback sequences NACK, o_cc3,o_cc4,o_cc5,o_cc7, NACK, NACK, I.e. in 7 final bit ACKs/NACK feedback sequences o_i, i=0,1 ..., O^ACKIn -1, o₀~o₅For The first ACK/NACK feedback sequences determined according to DAI, o₆=NACK；

Situation 2：Assuming that judging there is SPS PDSCH transmissions on the packet loss of carrier wave 2, i.e. carrier wave 1, then eventually End produces the corresponding ACK/NACK of 1 bit SPS PDSCH, is mapped in the first ACK/NACK anti- Present after sequence, i.e. last position in the final ACK/NACK feedback sequences of 7 bits is obtained Final 7 bit ACKs/NACK feedback sequences NACK,o_cc3,o_cc4,o_cc5,o_cc7, NACK, ACK/NACK, i.e., in 7 final bit ACKs/NACK Feedback sequence o_i, i=0,1 ..., O^ACKIn -1, o₀~o₅For the first ACK/NACK determined according to DAI Feedback sequence, o₆=SPS PDSCH 1 bit ACK/NACK；

In above-mentioned two situations, O^ACKAll it is 7 bits, although according to different terminal estimate of situations, most Whole ACK/NACK feedback sequences o_i, i=0,1 ..., O^ACKThe physical significance of last 1 bit in -1 Difference, but according to the mapping position and bit number all phases of DAI the first ACK/NACK feedback sequences determined Together, thus ensure this partial feedback information of base station with terminal-pair understanding it is consistent；For last 1 bit feedback Information：

If base station have sent SPS PDSCH on carrier 1 really, the dynamic sent on carrier 2 PDSCH or the Physical Downlink Control Channel of indicating downlink SPS resources release, if then terminal is interpreted as feelings The understanding of condition 2, base station and terminal is completely the same, if terminal is interpreted as situation 1, base station is received SPS PDSCH feedback information be NACK, again transmission can (if next time retransmit terminal do not have There is similar above-mentioned packet drop, i.e., receive information on carrier 1, then can directly judge SPS PDSCH whether there is, so as to avoid always producing SPS PDSCH NACK situation)；

If SPS PDSCH are bundled in dynamic PDSCH transmit on carrier 1 by base station, if Terminal is interpreted as situation 1, and the understanding of base station and terminal is completely the same, if terminal is interpreted as situation 2, Base station can ignore last 1 bit feedback information, it is believed that merely to ensureing ACK/NACK feedback bits The occupy-place transmission that number is constant and carries out, without actual physical significance.

Embodiment 2：It is assumed that the transmission mode of each carrier wave is 1TB, i.e., each carrier wave If necessary to ACK/NACK feedbacks, then 1 bit ACK/NACK is corresponded to；Assuming that carrier wave 1 is main member The descending son of the progress ACK/NACK feedbacks in same sub-frame of uplink n is needed on carrier wave, each carrier wave Frame number is 2, i.e. M=2, and subframe n-k2 (i.e. sf2) is SPS subframes：

End side according to reality 9 carrier waves and subframe to (such as carrier wave 1 and subframe n-k1 are a pair, Downlink transfer is have received on one downlink transfer of correspondence, by that analogy), and finally receive C-DAI=4 and T-DAI=1, judge T-DAI indicate for 13, that is, have 13 carrier waves and subframe to upper It there are the carrier wave and/or indicating downlink of the Physical Downlink Shared Channel of corresponding Physical Downlink Control Channel The physical downlink control channel transmission of SPS resources release, i.e., the first ACK/NACK determined according to DAI Number of bits of feedback is 13 bits；

Due to there is SPS subframes in feedback window, then terminal determines actual ACK/NACK feedback bits Number O^ACK=13+1=14 bits；

The ACK/NACK of the downlink transfer received is mapped to 13 bits by terminal according to C-DAI orders Relevant position in first ACK/NACK feedback sequences, and is produced from the position for being not received by downlink transfer Raw NACK, obtains the ACK/NACK feedback sequences of 13 bit the first NACK,o_cc2,sf1,o_cc3,sf1,NACK,o_cc5,sf1,o_cc7,sf1,o_cc8,sf1,NACK,o_cc3,sf2,o_cc4,sf2,o_cc5,sf2,o_cc7,sf2,NACK , wherein o_cci,sfjFor correspondence carrier wave and the ACK/NACK feedback bits of subframe pair；

Terminal is according to the Physical Downlink Control Channel received in carrier wave 8 and subframe n-k1 (i.e. sf1) position In C-DAI=4 and received in carrier wave 3 and subframe n-k2 (i.e. sf2) position physical down control C-DAI=1 in channel, judges have a carrier wave to lose before the carrier wave 3 on subframe n-k2 (i.e. sf2) Bag, specifically includes situations below：

Situation 1：Assuming that judging the packet loss of carrier wave 1 on subframe n-k2 (i.e. sf2), i.e. SPS PDSCH It is packaged in dynamic PDSCH and transmits, without SPS PDSCH in feedback window, terminal produces 1 bit NACK, is mapped in after the first ACK/NACK feedback sequences, i.e. the final ACK/NACK of 14 bits Last position in feedback sequence, obtains final 14 bit ACKs/NACK feedback sequences NACK,o_cc2,sf1,o_cc3,sf1,NACK,o_cc5,sf1,o_cc7,sf1,o_cc8,sf1,NACK,o_cc3,sf2,o_cc4,sf2,o_cc5,sf2,o_cc7,sf2,NACK,NACK , i.e., in 14 final bit ACKs/NACK feedback sequences o_i, i=0,1 ..., O^ACKIn -1, o₀~o₁₂ For the first ACK/NACK feedback sequences determined according to DAI, o₁₃=NACK；

Situation 2：Assuming that judging the packet loss of carrier wave 2 on subframe n-k2 (i.e. sf2), i.e., exist on carrier wave 1 SPS PDSCH transmissions, then the corresponding ACK/NACK of 1 bit SPS PDSCH of terminal generation, map After the first ACK/NACK feedback sequences, i.e. the final ACK/NACK feedback sequences of 13 bits In last position, obtain final 13 bit ACKs/NACK feedback sequences NACK,o_cc2,sf1,o_cc3,sf1,NACK,o_cc5,sf1,o_cc7,sf1,o_cc8,sf1,NACK,o_cc3,sf2,o_cc4,sf2,o_cc5,sf2,o_cc7,sf2,NACK,ACK/NACK , i.e., in 14 final bit ACKs/NACK feedback sequences o_i, i=0,1 ..., O^ACKIn -1, o₀~o₁₂ For the first ACK/NACK feedback sequences determined according to DAI, o₁₃=SPS PDSCH 1 bit ACK/NACK；

In above-mentioned two situations, O^ACKAll it is 14 bits, although according to different terminal estimate of situations, Final ACK/NACK feedback sequences o_i, i=0,1 ..., O^ACKThe physics meaning of last 1 bit in -1 It is adopted different, but according to the mapping position and bit number of DAI the first ACK/NACK feedback sequences determined all It is identical, therefore ensure that the understanding of this partial feedback information of base station with terminal-pair is consistent；It is anti-for last 1 bit Feedforward information：

If base station have sent SPS PDSCH on the carrier wave 1 really on subframe n-k2 (i.e. sf2), The dynamic PDSCH or indicating downlink SPS resources sent on carrier wave 2 on subframe n-k2 (i.e. sf2) is released The Physical Downlink Control Channel put, if then terminal is interpreted as situation 2, the understanding of base station and terminal is complete Consistent, if terminal is interpreted as situation 1, the feedback information for the SPS PDSCH that base station is received is NACK, again transmission (if retransmitting terminal next time similar above-mentioned packet drop does not occur, that is, can exist Information is received on carrier wave 1 on subframe n-k2 (i.e. sf2), then can directly judge that SPS PDSCH are It is no to exist, so as to avoid always producing SPS PDSCH NACK situation)；

If SPS PDSCH are bundled to dynamic by base station on the carrier wave 1 on subframe n-k2 (i.e. sf2) Transmitted in PDSCH, if then terminal is interpreted as situation 1, the understanding of base station and terminal be it is completely the same, If terminal is interpreted as situation 2, base station can ignore last 1 bit feedback information, it is believed that merely to protecting The occupy-place transmission that card ACK/NACK number of bits of feedback is constant and carries out, without actual physical significance.

It should be noted that only only supporting 1TB to be transmitted as with the transmission mode of each carrier wave in above-described embodiment Whether example, when the transmission mode of all or part of carrier wave supports 2TB transmission, and be configured with space conjunction And when, only influence to determine the first ACK/NACK number of bits of feedback and first according to DAI ACK/NACK feedback sequences, have no effect on the above-mentioned last position in final ACK/NACK feedback sequences The process of 1 bit feedback information of mapping is put, therefore is also included in the present invention.

In addition, in above-described embodiment using the subframe in the main member carrier in feedback window comprising SPS subframes as Trigger condition, as long as now including the SPS according to determined by the period assignment of SPS business in feedback window Subframe, no matter whether whether the SPS business in the SPS subframes is activated (have received indicating downlink SPS The Physical Downlink Control Channel of resource active), it is carried out the corresponding operating in above-described embodiment.Certainly may be used also SPS subframes are included so that the condition to be changed into the subframe in the main member carrier in feedback window and received SPS arrived in the Physical Downlink Control Channel of indicating downlink SPS resource actives, the i.e. feedback window Frame has been activated can be in transmission SPS PDSCH, i.e. above-described embodiment 1, when condition is current Subframe i is SPS subframes and has been received that the Physical Downlink Control Channel of indicating downlink SPS resource actives Corresponding operating in Shi Zhihang embodiments；In above-described embodiment 2, when condition is subframe n-k2 (i.e. sf2) Held for SPS subframes and when having been received that the Physical Downlink Control Channel of indicating downlink SPS resource actives Corresponding operating in row embodiment；Or the condition can also be changed into and be configured for SPS business, i.e., now The SPS subframes according to determined by the period assignment of SPS business might not be included in feedback window, also not Certain Physical Downlink Control Channel that have received indicating downlink SPS resource actives, as long as terminal is configured for The corresponding configuration of SPS business, such as the cycle, is then carried out the corresponding operating in above-described embodiment.
