相关申请的交叉引用
本申请主张在2017年9月8日在中国提交的中国专利申请号No.201710806257.X的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别涉及一种反馈信息传输方法、装置、终端、基站及计算机可读存储介质。
背景技术
目前，在LTE系统中，终端在一个子帧中在一个服务小区中只能接收一个物理下行共享信道PDSCH(Physical Downlink Shared CHannel)。对于频分双工FDD(Frequency Division Dual)系统，反馈时序为n-4，即子帧n-4中接收到的PDSCH在子帧n中进行肯定确认ACK和/或否定确认NACK(ACKnowledgement/Non-ACKnowledgement)反馈。对于时分双工TDD(Time Division Duplexing)系统，反馈时序对不同的TDD上下行配置不同，例如如表1所示，即在子帧n-k中接收到的PDSCH在子帧n中进行ACK和/或NACK反馈，其中K集合可能包含超过一个元素，此时意味着多个下行子帧中的PDSCH需要在同一个上行子帧n中进行ACK和/或NACK反馈，终端按照调度的下行子帧的先后顺序对产生ACK和/或NACK进行排序，得到一个包含多比特的ACK和/或NACK反馈信息序列。这种排序在终端和基站侧是采用相同规则的，因此，基站在获得ACK和/或NACK反馈信息序列时，可以正确确定哪个ACK和/或NACK反馈比特与哪个调度子帧中的PDSCH相对应，从而做出正确的重传操作。
表1：TDD系统中，上行子帧对应的下行子帧索引集合K:{k 0,k 1,…k M-1}
Figure PCTCN2018102682-appb-000001
*注：以一个无线帧为例给出了每个上行子帧所对应的K的情况，其中n-k＜0表示前一无线帧中的下行子帧。
但是，随着移动通信业务需求的发展变化，国际电信联盟(International Telecommunication Union，ITU)和第三代产业合作计划(3rd Generation Partnership Project，3GPP)等组织都开始研究新的无线通信系统，例如第五代无线通信系统(5Generation New RAT，5G NR)。在5G NR系统中，终端在一个服务小区中可以同时接收两个PDSCH。这两个PDSCH可以承载不同的传输块TB(Transport Block)信息，可以来自不同的发送接收节点TRP(Transmission Reception Point)。来自不同TRP的PDSCH使用不同的波束(Beam)传输。这两个PDSCH都需要对应ACK和/或NACK反馈信息，且这两个PDSCH的ACK和/或NACK反馈信息需要在同一时刻通过同一个上行信道传输。此种情况在LTE系统中并未有相关定义。
即相关技术对于如何在同一个服务小区上同时接收到的多个PDSCH进行ACK和/或NACK反馈还没有明确方法，导致ACK和/或NACK无法正确反馈。

由上可知，本公开实施例提供的上述方案能够很好的解决相关技术中对于同一个服务小区上同时接收到的多个PDSCH无法正确进行ACK和/或NACK反馈的问题。
下面结合终端和基站两侧对本公开实施例提供的所述反馈信息传输方法进行进一步说明。
针对上述技术问题，本公开实施例提供了一种反馈信息传输方法，主要是基站对beam进行分组，并将所述分组信息发送给终端，终端根据beam组个数确定HARQ-ACK反馈信息的比特数。下面针对终端侧和基站侧分别进行方案的详细介绍。
终端侧：
(1)终端接收配置信息，根据所述配置信息确定beam组个数。
(2)所述终端根据所述beam组个数确定HARQ-ACK反馈信息的比特数。
(3)所述终端产生与所述确定的HARQ-ACK反馈信息的比特数对应的HARQ-ACK反馈信息序列，发送给基站。
其中：
1.所述终端根据所述beam组个数确定HARQ-ACK反馈信息的比特数，具体包括：
(1)根据beam组个数K确定需要在当前上行时刻进行HARQ-ACK反馈的每个下行时刻对应的HARQ-ACK反馈比特数A。
其中，
Figure PCTCN2018102682-appb-000020
K为所述波束组个数，C i为对应使用波束组i中的波束传输的每个下行传输对应的HARQ-ACK比特数。
关于C i，例如，当传输模式为多TB时或传输模式为多TB且不使用HARQ-ACK空间合并时，C i＝Q，Q为TB个数；当传输模式为单TB时或传输模式为多TB且使用HARQ-ACK空间合并时，C i＝1。
又例如，当配置了基于码块组CBG的传输时，假设一个TB被分割为P个CBG，当传输模式为多TB时或传输模式为多TB且不使用HARQ-ACK空 间合并时，C i＝Q×P，当传输模式为单TB时或传输模式为多TB且使用HARQ-ACK空间合并时，C i＝P。
(2)进一步，根据在当前上行时刻进行HARQ-ACK反馈的下行时刻的个数M、每个下行时刻对应的HARQ-ACK反馈比特数A、配置或激活的服务小区和/或载波和/或带宽部分的个数N确定终端的HARQ-ACK反馈信息的比特数。
终端的HARQ-ACK反馈信息的比特数X＝M×A×N；或者，
Figure PCTCN2018102682-appb-000021
M i为每个配置或激活的服务小区和/或载波和/或带宽部分i上对应的M值，A i为每个配置或激活的服务小区和/或载波和/或带宽部分i上对应的A值。
M可以等于1，此时，可以仅根据每个下行时刻对应的HARQ-ACK反馈比特数A、配置或激活的服务小区和/或载波和/或带宽部分的个数确定终端的HARQ-ACK反馈信息的比特数；M也可以大于1。
N可以等于1，此时，可以仅根据在当前上行时刻进行HARQ-ACK反馈的下行时刻的个数M、每个下行时刻对应的HARQ-ACK反馈比特数A；N也可以大于1。
2.所述终端产生与所述确定的HARQ-ACK反馈信息的比特数对应的HARQ-ACK反馈信息序列，具体包括：
(1)对每个下行传输时刻产生A比特HARQ-ACK反馈信息序列：
a.对A比特HARQ-ACK反馈信息序列中对应没有接收到任何下行传输的位置产生NACK和/或DTX作为反馈信息(即当根据接收到的下行传输产生的HARQ-ACK反馈信息的比特数不足A时，需要补充NACK和/或DTX)；
b.按照预先约定或配置的beam组顺序，将对应使用属于不同beam组的beam传输的下行传输的HARQ-ACK反馈信息进行排序。
具体的，对于在同一个下行时刻接收到的使用属于不同beam组的beam传输的下行传输的HARQ-ACK反馈信息，按照beam组的编号从小到大或从大到小顺序排序在下行时刻对应的HARQ-ACK反馈信息序列中。例如，假设使用属于不同beam组的beam传输的下行传输所对应的HARQ-ACK反馈信息的比特数相同，对于在同一个下行时刻接收到的使用属于beam组k的 beam传输的下行传输的C比特HARQ-ACK反馈信息，排序在该下行时刻对应的HARQ-ACK反馈信息序列中的C×k-C到C×k-1位置，假设位置编号从0开始，k＝1,2,3，…K，K为beam组的个数；其中，当C＝1时，C×k-C和C×k-1为同一个位置，即一个下行传输仅对应1比特HARQ-ACK，仅占用该下行时刻对应的HARQ-ACK反馈信息序列中的一个位置，即C×k-1位置。又例如，假设使用属于不同beam组的beam传输的下行传输所对应的HARQ-ACK反馈信息的比特数不同，对于在同一个下行时刻接收到的使用属于beam组k的beam传输的下行传输的C k比特HARQ-ACK反馈信息，排序在该下行时刻对应的HARQ-ACK反馈信息序列中的
Figure PCTCN2018102682-appb-000022
到
Figure PCTCN2018102682-appb-000023
位置，k＝1,2,3，…K，K为beam组的个数，Ci为使用beam组i的beam传输的下行传输对应的HARQ-ACK反馈信息比特数；其中，当C k＝1时，
Figure PCTCN2018102682-appb-000024
和
Figure PCTCN2018102682-appb-000025
为同一个位置，即一个下行传输仅对应1比特HARQ-ACK，仅占用该下行时刻对应的HARQ-ACK反馈信息序列中的一个位置，即
Figure PCTCN2018102682-appb-000026
位置。
(2)当多个不同下行时刻中的下行传输需要在同一个上行时刻进行HARQ-ACK反馈时，
将每个下行时刻对应的HARQ-ACK反馈信息序列，按照传输时间顺序级联在一起，或按照下行传输所对应的下行分配索引DAI计数器中的值的顺序级联在一起；和/或
对没有接收到任何下行传输或判断丢包的下行时刻，产生A比特NACK和/或DTX作为反馈信息，A为至少根据K值确定的一个下行时刻对应的HARQ-ACK反馈比特数。
(3)当配置或激活的服务小区和/或载波和/或带宽部分的个数N大于1时，
将每个配置或激活的服务小区和/或载波和/或带宽部分对应的HARQ-ACK反馈信息序列，按照预定顺序级联在一起，例如按照服务小区和 /或载波和/或带宽部分的编号从小到大，或从大到小；和/或
对没有接收到任何下行传输或判断丢包的服务小区和/或载波和/或带宽部分，产生该服务小区和/或载波和/或带宽部分对应的HARQ-ACK比特数的NACK和/或DTX作为反馈信息。
其中，所述下行传输为下行共享信道，调度下行共享信道的下行控制信道，指示下行半持续调度SPS资源释放的下行控制信道中的一种或多种。
所述上行信道为上行控制信道和/或上行共享信道。
本实施例中，可以通过如下方式表现所述beam，即所述beam具体为：
(1)准共址QCL(Quasi-Co-Location)关系。此时beam组的配置可以表现为QCL的分组的配置，beam组的个数可以表现为QCL分组的个数，即将QCL关系分为多组，得到的组的个数。说明：即下行传输的DMRS的天线端口与通知的一个beam测量相关的参考信号的资源上的端口是QCL的，或下行传输的DMRS的天线端口与通知的一个beam测量相关的参考信号的资源上的一个端口是QCL的。例如，预先配置多个参数信号的资源或者资源+端口，在不同的资源或者不同的资源+端口情况下，通过测量和/或训练得到不同的发送接收组合结果，记录下来，作为对应的资源或对应的资源+端口上的传输方案(beam)，当通知终端一个QCL关系时，相当于通知了一个信道传输的DMRS与通知的参考信号的资源上的端口具有QCL关系，即需要使用该资源或资源+端口所对应的传输方案(beam)进行传输(收或发)，即使用记录下来的相对应的接收或者发送的预编码矩阵进行传输。
或者，(2)beam测量相关的参考信号(例如CSI-RS)的资源和/或端口。此时beam组的配置可以表现为参考信号的资源和/或端口的分组配置，beam组个数可以表现为参考信号的资源和/或端口分组的个数，即将参考信号的资源和/或端口分为多组，得到的组的个数。说明：此时，一个参考信号的资源上的所有端口对应一个beam，或一个参考信号的资源上的一个端口对应一个beam，不同端口可能对应不同的beam。例如，预先配置多个参数信号的资源或者资源+端口，在不同的资源或者不同的资源+端口情况下，通过测量和/或训练得到不同的发送接收组合结果，记录下来，作为对应的资源或对应的资源+端口上的传输方案(beam)，当通知终端一个参考信号的资源或资源+ 端口时，相当于通知了一个信道传输的DMRS与通知的参考信号的资源上的端口具有QCL关系，即需要使用该资源或资源+端口所对应的传输方案(beam)进行传输(收或发)，即使用记录下来的相对应的接收或者发送的预编码矩阵进行传输。
或者，(3)beam index(波束索引)。此时beam组的配置可以表现为对beam index的分组配置，beam组个数可以表现为beam index组的个数，即将beam index分为多组，得到的组的个数。说明：意味着标准中直接定义了beam，通过beam index可以确定该beam所对应的QCL关系。例如，在配置的多个考信号的资源上或资源以及相应端口上经过测量和/或训练得到不同的发送接收组合(例如使用的预编码矩阵的组合)的结果，被记录下来，可以发送接收组合直接定义为不同的beam，或者将发送接收组合中的接收定义为不同的beam，用beam index表示。
或者，(4)波束对关系BPL(Beam Pair Linkage)。此时beam组的配置可以表现为对BPL的分组配置，beam组个数可以表现为BPL组的个数，即将BPL分为多组，得到的组的个数。说明：发送端发送一个下行传输所使用的beam与接收端接收该下行传输所使用的beam的配对关系；通过BPL，可以确定终端接收下行传输使用的beam。说明：当一个TRP使用一个发送beam发送一个下行传输时，如PDCCH或PDSCH或下行参考信息(如CSI-RS等)，终端使用不同的接收beam接收该下行传输，即存在一个发送beam和一个接收beam之间的配对关系，称为波束对关系(BPL，Beam Pair Linkage)。BPL可以通过波束训练得到。例如，在配置的多个考信号的资源上或资源以及相应端口上经过测量和/或训练得到不同的发送接收组合(例如使用的预编码矩阵的组合)的结果，被记录下来，定义为不同的BPL。
关于beam指示的具体说明如下。
一般基站会预先配置给终端一个或多个PDCCH对应的beam，用于终端检测PDCCH。Beam可以通过通知终端下行信道的DMRS端口与不同的CSI-RS配置(例如端口、资源等)存在准共址(QCL，Quasi-Co-Location)关系来体现，这种QCL关系就意味着下行传输的DMRS端口所使用的beam与对应的参考信号配置所对应的beam是一致的，所谓beam相同或者一致， 即使用的预编码方式是相同的。因此如果预先定义了多种QCL关系，则可以直接通知其中一种或几种QCL关系给终端，通过QCL关系终端可以确定接收下行传输对应的候选beam集合。当然还可以直接通过通知某个CSI-RS配置(例如某个资源，或者某个资源上的某个端口)来达到通知终端所使用的beam的目的。Beam还可以通过BPL来体现，此时终端可能被预先配置了多个BPL。当通知终端其中一个BPL的index时，终端可以根据通知的BPL index确定对应的BPL，根据BPL中定义的发送和接收波束对，来确定所使用的beam。对于上述两种体现方式，相当于不需要定义beam，而通过其他定义方式隐含体现beam的意思。当然，beam还可以直接通过beam index来体现，此时终端预先被配置或定义了多个beam，终端可以根据通知的beam index来确定所使用的beam。Beam组可以通过上述beam的表现形式来配置。
基站侧：
(1)基站确定beam的分组，并发送配置信息指示所述beam的分组情况给终端。
(2)所述基站根据所述beam组个数确定HARQ-ACK反馈信息的比特数。
具体确定方案参见终端侧的确定方式，在此不再赘述。
(3)所述基站接收所述终端发送的与所述确定的HARQ-ACK反馈信息的比特数对应的HARQ-ACK反馈信息序列。
其中，基站可以是任何接收节点，例如TRP(发送接收节点)，传统基站，relay节点(中继节点)等等。
下面对本公开实施例提供的方案进行举例说明。
假设配置了6个CSI-RS资源(假设每个CSI-RS资源上如果存在多端口，则每个端口之间是QCL的，即使用相同的预编码矩阵，即使用相同的beam，当然也可以是6个CSI-RS资源+端口，例如每个CSI-RS上有2个端口，则配置3个CSI-RS资源即可得到6个CSI资源+端口的组合，如CSI-RS资源1的端口1，CSI-RS资源1的端口2，CSI-RS资源2的端口1，CSI-RS资源2的端口2，CSI-RS资源3的端口1，CSI-RS资源3的端口2)。每个CSI-RS资源经过beam训练后对应了一个或一组beam(即预编码矩阵)，例如CSI-RS 资源1对应beam1，CSI-RS资源2对应beam2，CSI-RS资源3对应beam3，CSI-RS资源4对应beam4，CSI-RS资源5对应beam5，CSI-RS资源6对应beam6。通过通知终端一个CSI-RS资源编号，可以隐含通知终端其下行传输的DMRS与一个CSI-RS资源之间的QCL关系，从而使终端获得下行传输对应的beam，例如通知终端CSI-RS资源1，即等同于通知下行传输的DMRS与CSI-RS资源1之间存在QCL关系，则意味着通知终端该下行传输使用beam1。将6个CSI-RS资源分为2组，例如组1为{CSI-RS资源1，CSI-RS资源2，CSI-RS资源3}，组2为{CSI-RS资源4，CSI-RS资源5，CSI-RS资源6}，即K＝2，则组1对应了beam1、2、3，组2对应了beam4、5、6。组1可以对应TRP1，组2可以对应TRP2，组1和组2与TRP的对应关系对于终端来说是不可见的，即这部分信息在协议中可以不做定义，由基站自行实现；终端假设在一个下行时刻，只能在一个组内的多个beam中的一个beam接收到下行传输，但可以在同一个下行时刻，在不同组内的beam上各接收到一个下行传输。例如：
情况1：假设一个上行时刻仅对应一个下行时刻的HARQ-ACK反馈信息：
基站侧：
在下行时刻1，使用组1中的beam1(beam1可以代表的是发送和接收beam的组合，也可以是终端接收beam，无论是组合还是接收beam，对终端而言只需要确定接收beam即可，下同)发送一个PDCCH1，该PDCCH1调度一个使用组1中的一个beam的PDSCH1(可以同样使用beam1，当然也可以使用组1中的其他beam，例如beam2，下同)；同时，使用组2中的beam4发送了一个PDCCH2，该PDCCH2调度一个使用组2中的一个beam的PDSCH2(可以同样使用beam4，当然也可以使用组2中的其他beam，例如beam5，下同)；
终端侧：
在下行时刻1，检测PDCCH(检测PDCCH使用的beam集合可以是预先配置的上述beam组中的beam的子集，例如{beam1，beam4}，可以通过通知相应的CSI-RS资源来实现对beam的通知，或者如果没有通知子集，则为上述beam组的全集，即{beam1～6}，下同)；假设PDSCH都对应C＝1个 HARQ-ACK反馈信息(当然可以根据TB数、CBG个数确定对应多比特HARQ-ACK反馈信息，处理方式类似，不再赘述)，终端可以确定下行时刻1对应的HARQ-ACK序列的比特数为C×K＝2(对应2组beam)；当终端检测到使用beam1的PDCCH1以及使用beam4的PDCCH2时，进一步根据PDCCH中的调度信息接收对应的PDSCH1和PDSCH2，并对PDSCH1和PDSCH2产生HARQ-ACK反馈信息；由于PDCCH1以及PDSCH1所使用的beam都属于组1，PDCCH2以及PDSCH2所使用的beam都属于组2，则不论根据PDCCH所使用的beam或是PDSCH所使用的beam，都可以确定PDSCH1对应的1比特HARQ-ACK排序在下行时刻1对应的HARQ-ACK序列的第1个位置，即如果从0开始编号，k＝1对应组1，则为编号为C×k-C＝0的位置，确定PDSCH2对应的1比特HARQ-ACK排序在下行时刻1对应的HARQ-ACK序列的第2个位置，即如果从0开始编号，k＝2对应组2，为编号为C×k-C＝1的位置，例如假设PDSCH1对应ACK，PDSCH2对应NACK，则下行时刻1对应的HARQ-ACK序列为{ACK，NACK}；
终端在下行时刻1对应的反馈HARQ-ACK的反馈时刻，在PUCCH(物理上行控制信道)和/或PUSCH(物理上行共享信道)上传输上述2比特{ACK，NACK}；
基站侧：
在下行时刻1对应的反馈HARQ-ACK的反馈时刻，在PUCCH和/或PUSCH上接收上述2比特{ACK，NACK}，并按照上述终端侧同样的排序过程解析(可与终端提前约定排序过程)，第1个反馈信息比特ACK对应PDSCH1，则PDSCH1不需要重传，第2个反馈信息比特NACK对应PDSCH2，则PDSCH2需要重传；
如果终端被配置了多个服务小区，则每个服务小区上都按照上述过程产生下行时刻1对应的HARQ-ACK序列，将多个服务小区在下行时刻1对应的HARQ-ACK序列按照服务小区的编号顺序级联在一起，在下行时刻1对应的反馈HARQ-ACK的反馈时刻，在PUCCH和/或PUSCH上传输；基站侧则按照上述相同的级联顺序解析接收到的HARQ-ACK序列，从而得到每个服务小区以及每个服务小区上的下行时刻的PDSCH对应的HARQ-ACK反馈 信息。
情况2：假设一个上行时刻对应多个下行时刻的HARQ-ACK反馈信息：
基站侧：
在下行时刻1，使用组1中的beam1发送一个PDCCH1，该PDCCH1调度一个使用组1中的一个beam的PDSCH1；同时，使用组2中的beam4发送了一个PDCCH2，该PDCCH2调度一个使用组2中的一个beam的PDSCH2；
在下行时刻2，使用组1中的beam1发送一个PDCCH3，该PDCCH3调度一个使用组1中的一个beam的PDSCH3；同时，使用组2中的beam4发送了一个PDCCH4，该PDCCH4调度一个使用组2中的一个beam的PDSCH4；
终端侧：
在下行时刻1，检测PDCCH；假设PDSCH都对应C＝2个HARQ-ACK反馈信息(当然可以根据TB数、CBG个数确定对应多比特HARQ-ACK反馈信息，处理方式类似，不再赘述)，终端可以确定下行时刻1对应的HARQ-ACK序列的比特数为C×K＝4(对应2组beam)；当终端检测到使用beam1的PDCCH1以及使用beam4的PDCCH2时，进一步根据PDCCH中的调度信息接收对应的PDSCH1和PDSCH2，并对PDSCH1和PDSCH2产生HARQ-ACK反馈信息；由于PDCCH1以及PDSCH1所使用的beam都属于组1，PDCCH2以及PDSCH2所使用的beam都属于组2，则不论根据PDCCH所使用的beam或是PDSCH所使用的beam，都可以确定PDSCH1对应的2比特HARQ-ACK排序在下行时刻1对应的HARQ-ACK序列的第1和2个位置，即如果从0开始编号，k＝1对应组1，则为编号为C×k-C＝0到C×k-1＝1的位置，确定PDSCH2对应的2比特HARQ-ACK排序在下行时刻1对应的HARQ-ACK序列的第3和4个位置，即如果从0开始编号，k＝2对应组2，则为编号为C×k-C＝2到C×k-1＝3的位置，例如假设PDSCH1对应ACK，ACK，PDSCH2对应NACK，NACK，则下行时刻1对应的HARQ-ACK序列为{ACK，ACK，NACK，NACK}；
在下行时刻2，检测PDCCH；假设PDSCH都对应C＝2个HARQ-ACK反馈信息(当然可以根据TB数、CBG个数确定对应多比特HARQ-ACK反馈信息，处理方式类似，不再赘述)，终端可以确定下行时刻2对应的 HARQ-ACK序列的比特数为C×K＝4(对应2组beam)；当终端检测到使用beam1的PDCCH3以及使用beam4的PDCCH4时，进一步根据PDCCH中的调度信息接收对应的PDSCH3和PDSCH4，并对PDSCH3和PDSCH4产生HARQ-ACK反馈信息；由于PDCCH3以及PDSCH3所使用的beam都属于组1，PDCCH4以及PDSCH4所使用的beam都属于组2，则不论根据PDCCH所使用的beam或是PDSCH所使用的beam，都可以确定PDSCH3对应的2比特HARQ-ACK排序在下行时刻2对应的HARQ-ACK序列的第1和2个位置，即如果从0开始编号，k＝1对应组1，则为编号为C×k-C＝0到C×k-1＝1的位置，确定PDSCH4对应的2比特HARQ-ACK排序在下行时刻2对应的HARQ-ACK序列的第3和4个位置，即如果从0开始编号，k＝2对应组2，则为编号为C×k-C＝2到C×k-1＝3的位置，例如假设PDSCH3对应NACK，NACK，PDSCH4对应ACK，NACK，则下行时刻2对应的HARQ-ACK序列为{NACK，NACK，ACK，NACK}；
终端将上述下行时刻1和时刻2分别对应的HARQ-ACK序列级联在一起，例如按照下行时刻的前后顺序，下行时刻2对应的HARQ-ACK序列级联在下行时刻1对应的HARQ-ACK序列之后，或者按照下行时刻1和下行时刻2中传输的PDCCH中的DAI计数器的值，按照DAI值的从小到大或从大到小顺序排序，得到级联后的8比特HARQ-ACK序列{ACK，ACK，NACK，NACK，NACK，NACK，ACK，NACK}；
终端在下行时刻1和下行时刻2共同对应的反馈HARQ-ACK的反馈时刻，在PUCCH和/或PUSCH上传输上述8比特{ACK，ACK，NACK，NACK，NACK，NACK，ACK，NACK}；
基站侧：
在下行时刻1和下行时刻2共同对应的反馈HARQ-ACK的反馈时刻，在PUCCH和/或PUSCH上接收上述8比特{ACK，ACK，NACK，NACK，NACK，NACK，ACK，NACK}，并按照上述终端侧同样的排序过程解析，第1、2个反馈信息比特ACK、ACK对应PDSCH1(例如对应PDSCH1的两个TB，或如果PDSCH1为1个TB但分为2个CBG，则分别对应每个CBG，下同)，则PDSCH1不需要重传，第3、4个反馈信息比特NACK、NACK对 应PDSCH2，则PDSCH2需要重传，第5、6个反馈信息比特NACK、NACK对应PDSCH3，则PDSCH3需要重传，第7、8个反馈信息比特ACK、NACK对应PDSCH4，则PDSCH4的第二个TB或第二个CBG需要重传；
如果终端被配置了多个服务小区，则每个服务小区上都按照上述过程产生下行时刻1和下行时刻2对应的HARQ-ACK序列级联后的HARQ-ACK序列，将多个服务小区对应的HARQ-ACK序列按照服务小区的编号顺序级联在一起，在下行时刻1和下行时刻2共同对应的反馈HARQ-ACK的反馈时刻，在PUCCH和/或PUSCH上传输；基站侧则按照上述相同的级联顺序解析接收到的HARQ-ACK序列，从而得到每个服务小区以及每个服务小区上的不同下行时刻的PDSCH对应的HARQ-ACK反馈信息。
上述举例以通过配置CSI-RS资源来通知beam，当然通过通知beam index或BPL或QCL关系等通知beam的方式同样适用，不再赘述。此外，上述情况以一个服务小区和/或载波和/或带宽部分为例，如果配置了或者激活了多个服务小区和/或载波和/或带宽部分，则每个部分按照上述方式得到对应的HARQ-ACK反馈信息序列，将多个服务小区和/或载波和/或带宽部分的级联在一起即可。
由上可知，本公开实施例提供的方案主要根据beam组确定HARQ-ACK反馈比特数以及根据beam组index排序HARQ-ACK，适用不同beam组中的beam传输的下行传输对应的HARQ-ACK反馈信息；可以保证当终端同时接收到多个使用不同beam的下行传输时，正确的产生ACK和/或NACK反馈信息，保证终端和基站对ACK和/或NACK反馈信息的理解一致。

其中，HARQ-ACK即为下行传输的反馈信息，包括ACK、NACK，还可能包括DTX，如果下行传输接收正确，则为ACK，接收错误或者丢失则为NACK或DTX。
