现有技术中，会对一个TRP所对应的所有服务小区(或者载波组件Carrier Component，CC)和高层配置的符合要求的PUCCH检测时机Occasion生成一个HARQ的HARQ-ACK比特集合，比如HARQ-ACK码本，HARQ-ACK子码本，并在PUCCH资源或者PUSCH资源中反馈所述的HARQ-ACK码本，其中，HARQ-ACK码本的编码顺序是先频域后时域的方案，即先排第1个Occasion中的不同CC从小到大排列，然后排下一个Occasion的不同CC从小到大排列，直到排完所有的高层配置的Occasion。协作传输的多个TRP的HARQ-ACK反馈类别包括：独立HARQ反馈和联合HARQ-ACK反馈，其中，独立HARQ-ACK反馈(separated ACK/NACK feedback，也可以称作独立ACK/NACK反馈，或者分别ACK/NACK反馈，或者分别HARQ-ACK反馈，这里ACK/NACK信息也可以写作HARQ-ACK)，即通过生成M个HARQ-ACK码本，通过物理上行资源反馈，比如在一个时间单元中不同CORESET组或CORESET对应的HARQ-ACK信息分别在不同的PUCCH中反馈。联合ACK/NACK反馈(或者联合HARQ-ACK反馈)，即通过生成1个HARQ-ACK码本，通过1个物理上行资源反馈，比如在一个时间单元中不同CORESET组或者CORESET对应的HARQ-ACK信息合并到一个PUCCH中反馈，例如，第一个CORESET组对应的HARQ-ACK子码本后面级联第二个CORESET组对应的HARQ-ACK子码本。需要说明的是，HARQ-ACK在一个HARQ-ACK码本中反馈是指所述HARQ-ACK码本中包括所述HARQ-ACK信息，并通过所述HARQ-ACK码本所对应的物理上行资源反馈。
为了提高数据或者信令传输的可靠性，一种方式是重复(即repetition)的传输。M个数据(比如，PDSCH或PUSCH)传输是repetition的，是指所述M个数据携带了完全相同的信息，比如M个数据来自相同传输块 (Transport Block，TB)，只是对应的信道编码后的冗余版本(Redundancy version，RV)不同，甚至M个数据连信道编码后的RV都是一样的。这里的RV是指对传输数据进行信道编码后的不同冗余版本，一般来说，可以取信道版本{0，1，2，3}。同样的，M个信令(比如PDCCH或PUCCH)传输是repetition的，是指所述M个信令携带的内容是相同的，比如M个PDCCH携带的DCI内容是相同的(比如每个域的取值都相同)，比如M个PUCCH携带的内容取值是相同的。其中，M个repetition的数据(比如M个repetition PUSCH或M个repetition PDSCH)或者M个repetition的信令(比如M个repetition PUCCH或M个repetition PDCCH)可以来自M个不同的TRP，或者来自M个不同的天线面板，或者M个不同的带宽部分(Bandwidth Part，BWP)，或者M个不同的载波组件(Carrier Component，CC)，其中所述的M个面板或者M个BWP或者M个CC可以属于同一个TRP，也可以属于多个TRP，。其中重复传输的方案包括但不限于以下至少方式之一：空分复用的方式Scheme 1，频分复用的方式Scheme 2，时隙内的时分复用的方式传输Scheme 3，时隙间的时分复用的方式Scheme 4，其中，频分复用的方式Scheme 2根据传输块的编码冗余版本(即Redundancy version)是否相同又分成两类，当所述重复传输的数据对应的RV版本相同时为Scheme2a，否则为Scheme2b，M为大于1的整数。当然还可以是上述复用方式的任意组合，比如空分复用和频分复用的组合，时分复用和频分复用的组合等。
这里，PDCCH是需要映射到一组资源单元(Resource Element，RE)上的，比如包括一个或者多个控制信道单元(Control Channel Element，CCE)，其中，一个RE在频域上包括一个子载波，而在时域上包括一个符号。而用于传输PDCCH的一个或者多个CCE的集合，有时也叫控制资源集合(Control resource set，CORESET)，其在频域上包括多个物理资源块，而在时域上包括K个符号，K为自然数，比如K可以取1、2、3的整数。这里符号包括但不限于以下之一：正交频分复用符号(Orthogonal Frequency Division Multiplex，OFDM)，单载波频分复用多址接入 (Single-Carrier Frequency Division Multiple Access，SC-FDMA)，正交频分复用多址接入(Orthogonal frequency division Multiple Access，OFDMA)。而为了检测PDCCH，将某个聚合等级的候选PDCCH配置成一个集合，这个等级的下的候选PDCCH集合就是搜索空间(Search Space，SS)，而多个搜索空间的集合形成一个搜索空间集合(SS set，SSSET，或SSS)，每个终端可以配置至少一个搜索空间集合。而为了检测PDCCH。会在搜索空间里配置当前终端的PDCCH检测的时机(即occasion)，以及检测的PDCCH候选(即candidate)，或PDCCH候选，其中occasion又叫PDCCH监测时机(即PDCCH monitoring occasion)，occasion由激活的下行带宽部分(Bandwidth Part，BWP)上的PDCCH监测周期(即PDCCH monitoring periodicity)，PDCCH的监测偏置(即PDCCH monitoring offset)，PDCCH监测图样(即PDCCH monitoring pattern)等确定的检测PDCCH的时域信息。candidate又叫PDCCH检测候选(即PDCCH monitoring candidate)，是一个搜索空间配置的候选的待检测的PDCCH，另外，PDCCH包括多种格式，每种格式都对应一个相对应格式下的下行控制信息DCI，每个DCI中又包括多个具体的信令指示域，其中检测也可以称为监测，盲检，主要是用来确定候选的多个PDCCH哪个是用于给终端传输下行控制信息的PDCCH，也可以将多个CORESET分成多个CORESET组，每个CORESET组至少包括一个CORESET。
这里，为了更好地传输PUSCH或者PDSCH，将连续K1个符号和L1个频域子载波的一组RE形成一个资源块(Resource block，RB，有时也叫物理资源块，Physical Resource block，PRB，或RB)，K和L为正整数，比如K＝12或者14，L＝12。而L2连续的虚拟的RB组成一个资源块组(Resource block Group，RBG)，L2为正整数，比如4或者8，可以通过高层信令配置取值，虚拟RB是通过RB经过一些资源映射后得到的RB。而对于使用了相同预编码的连续的RB称为也预编码资源组(Preceding resource block group，PRG)，它一般包括2个或者4个连续的RB。
本申请中信号为用于测量各种参数的参考信号，比如，可以包括但不 限于信道状态信息-参考信号(Channel State Information-Reference Signal，CSI-RS)资源、同步信号块(Synchronization Signals Block，SSB)资源、物理广播信道(Physical Broadcast Channel，PBCH)资源、同步广播块/物理广播信道(SSB/PBCH)资源、上行探测参考信号(Sounding reference signal，SRS)资源、定位参考导频(Positioning Reference Signals，PRS)，相位噪声参考信号(Phase-tracking reference signal，PTRS)。其中，CSI-RS资源主要是指非零功率信道状态信息-参考信号(Non Zero Power Channel State Information-Reference Signal，NZP-CSI-RS)资源。干扰测量资源可以包括但不限于信道状态信息干扰测量(Channel State Information-Interference Measurement，CSI-IM)、用于干扰测量的NZP-CSI-RS(NZP-CSI-RS for Interference Measurement)、零功率信道状态信息-参考信号(ZP-CSI-RS)，其中CSI-RS和SRS的作用又包括用于测量CSI，波束管理，时频跟踪，移动性管理等功能。
本申请中，信道包括但不限于以下至少之一：PDSCH、PDCCH、PUSCH、PUCCH，控制信道包括但不限于PDCCH和/或PUCCH。

可选实施方式一
本可选实施方式用于说明M个repetition传输的PDCCH调度一个PDSCH，且独立HARQ-ACK反馈，HARQ-ACK码本的构造问题。
其中，以M大于或者等于2个TRP为例说明，为了提高可靠性，所述的M个TRP通过重复传输技术(repetition)在时域，频域，空域中的至少一个域重复传输M次PDCCH，所述的M次PDCCH的内容可以是一样的，它们都调度同一个PDSCH。这里，每个TRP可以通过载波聚合技术同时在多个CC传输PDSCH。
这里，M个PDCCH对应M个CORESET组，每个CORESET组对应一个TRP，M个PDCCH分别对应M个HARQ-ACK码本，即分别反馈ACK/NACK(separated ACK/NACK feedback，或者独立HARQ-ACK反馈)。
终端接收所述M个PDCCH，分别进行盲检，并根据盲检的结果确定调度的PDSCH的时频资源，以接收所述PDSCH，并对所述PDSCH进行解调，如果解调正确，则HARQ-ACK为ACK，否则为NACK。对当前的检测时机Occasion和当前的CC，所述的PDSCH对应的HARQ-ACK在预定的HARQ-ACK码本中反馈，比如第一个HARQ-ACK码本中反馈，即使第一个PDCCH没有被检测到，也在第一个HARQ-ACK码本中反馈。这里，预定的HARQ-ACK码本可以是高层配置的HARQ-ACK，或者 HARQ-ACK码本索引值最小的HARQ-ACK码本，或者HARQ-ACK码本索引值最打的HARQ-ACK码本。如果只有一个HARQ-ACK码本，那么就在所述的HARQ-ACK码本里反馈所述的HARQ-ACK。
基站通过接收携带预定HARQ-ACK码本的物理上行信道获得所述PDSCH对应的HARQ-ACK码本，从而确定PDSCH的HARQ-ACK信息。
需要说明的是，本可选实施方式中的TRP也可以替换成天线面板，BWP，CC中的至少之一的传输资源，即可以通过M个天线面板或M个BWP或M个CC来传输所述的M个PDCCH。
这里，HARQ-ACK，也可以称为HARQ应答信息，或者HARQ-ACK信息，取值为ACK或NACK。
可选实施方式二
本可选实施方式用于说明M个repetition传输的PDCCH调度一个PDSCH，且联合HARQ-ACK反馈，HARQ-ACK码本的构造问题。
其中，以M大于或者等于2个TRP为例说明，为了提高可靠性，所述的M个TRP通过重复传输技术(repetition)在时域，频域，空域中的至少一个域重复传输M次PDCCH，所述的M次PDCCH的内容可以是一样的，它们都调度同一个PDSCH。这里，每个TRP可以通过载波聚合技术同时在多个CC传输PDSCH。
本可选实施方式中，M个PDCCH对应M个CORESET组，每个CORESET组对应一个TRP，M个PDCCH分别对应1个联合的HARQ-ACK码本，即联合反馈ACK/NACK(Joint ACK/NACK feedback)。
终端接收所述M个PDCCH，分别进行盲检，并根据盲检的结果确定调度的PDSCH的时频资源，以接收所述PDSCH，并对所述PDSCH进行解调，如果解调正确，则HARQ-ACK为ACK，否则为NACK。对当前的检测时机Occasion和当前的CC，所述第i个PDCCH对应第i个HARQ-ACK子码本，且所述PDSCH对应的HARQ-ACK在M个HARQ-ACK子码本中相同，要么都为ACK，要么都为NACK，i＝1，…， M，将M个HARQ-ACK子码本级联成一个联合的码本，比如将第k个HARQ-ACK子码本的比特信息放在第k-1个HARQ-ACK子码本的比特信息后面级联成一个新的HARQ-ACK码本，并通过一个上行物理信道反馈所述的HARQ-ACK码本，k＝2，…，M。
基站通过接收携带HARQ-ACK码本的物理上行信道以获得HARQ-ACK码本，从而获得所述PDSCH的HARQ-ACK。
需要说明的是，本可选实施方式中的TRP也可以替换成天线面板，BWP，CC中的至少之一的传输资源，即可以通过M个天线面板或M个BWP或M个CC来传输所述的M个PDCCH。
这里，HARQ-ACK，也可以称为HARQ应答信息，或者HARQ-ACK信息，取值为ACK或NACK。
可选实施方式三
本可选实施方式用于说明M个repetition传输的PDSCH的预编码信息确定问题。
本可选实施方式以M大于或者等于2个TRP为例说明，为了提高可靠性，所述的M个TRP通过重复传输技术(repetition)在时域，频域，空域中的至少一个域重复传输M次PDSCH，所述M次重复传输的PDSCH可以来自同一个传输块的相同的或者不同RV版本。
在本可选实施方式中，M个TRP，每个TRP对应一个CORESET组，高层信令可以为每个CORESET配置一个高层索引，比如CORESET group index i，i＝0，…，M-1。每个CORESET组对应一个传输配置指示状态(Transmission Configuration Indicator state，TCI state)，每个TCI state包括至少一个参考信号和至少一个准共位置类型，其中，准共位置(Quasi co-location，QCL)包括至少4种类型，根据保护的大尺度信息的种类不同，分成QCL-Type A，QCL-Type B，QCL-Type C，QCL-Type D。
其中，M个TRP通过频分复用的方式repetition传输M个PDSCH，每个TRP的PDSCH对应一个TCI state，终端和基站通过所述的TCI state 来确定PDSCH来自哪个TRP，或者确定第i个PDSCH对应第i个TCI state，TCI state相同的PDCCH、PDSCH、参考信号来自相同的TRP，这里的TRP也可以换成K个TRP的M个面板，或者K个TRP的M个CC，这里的K为小于等于M的正整数，可以取值为1。
基站在配置给终端的时频资源时，相同TCI对应的PRG里的连续RB使用了相同的预编码，而不同TCI对应的PRG里的连续RB使用了不同的预编码。或者两个TCI state对应的频域资源非连续，或者基站假设相同的预编码被用于任何连续分配的RB中，所述的连续的RB在一个PRG里并且对应相同的TCI state。
终端在接收PDSCH的时候，终端假设相同的预编码被用于任何连续分配的RB中，所述的连续的RB在一个PRG里并且对应相同的TCI state。
也就是说，终端或基站都假设TCI sate相同的PRG里的RB是连续的，使用相同的预编码，而TCI state不同的PRG对应的RB是不连续的，需要使用不同的预编码，这是因为不同的TCI state对应了不同的TRP，它们一般的预编码都不同，不能联合进行信道估计。
可选实施方式四
本可选实施方式用于说明M个TRP传输的PDSCH扰码个数小于CORESET组的个数的参数确定问题。
其中，以M大于或者等于2个TRP为例说明，每个TRP可以通过载波聚合技术同时在多个CC传输PDSCH，比如每个TRP至少包括一个CC。这里假设每个CORESET组对应一个TRP，且每个CORESET组对应的PDCCH调度的PDSCH是独立HARQ-ACK反馈，即有M个独立的HARQ-ACK码本。
在一次传输中，第i个TRP只用了一个CC进行了数据传输，比如只用了CC1传输PDSCH，那么基站或者终端都确定在第i个TRP对应的HARQ-ACK码本中不包括CC1外的其它HARQ响应，即只反馈CC1的ACK/NACK，第i个TRP可以是M个TRP中的任何一个TRP。
在一次传输中，第k个CC只有一个PDSCH扰码(PDSCH scrambling)，则只有一个TRP在第k个CC上传输了PDSCH，这里k可以是正整数，比如1，2，3，4，终端只接收一个TRP的第k个CC上的PDSCH。在这种场景下，如果所述M个CORESET组对应的PDCCH调度的PDSCH联合反馈ACK/NACK，那么，高层可以只配置一个CORESET组。
在一次传输中，第j个CORESET组对应的BWP或者CC不包括PDSCH扰码，则基站和终端都确定所述的CORESET组对应的基站不传输PDSCH，第j个CORESET组可以是M个CORESET组中的任何一个CORESET组，j取值为1，…，M中的一个。
在一次传输中，所述M个CORESET组关联到相同的PDSCH扰码上。且所述M个CORESET组调度的PDSCH在不重叠的时域上传输，或者在不重叠的频域上传输。
可选实施方式五
本可选实施方式用于说明M个TRP传输的PDSCH扰码个数大于CORESET组的个数的参数确定问题。
本可选实施方式以M大于或者等于2个TRP为例说明，每个TRP可以通过载波聚合技术同时在多个CC传输PDSCH，比如每个TRP至少包括一个CC。这里假设每个CORESET组对应一个TRP。
在一次传输中，通过高层信令在第j个CORESET组中配置PDSCH扰索引(或者说PDSCH扰码指示indicator，ID)所述PDSCH扰码索引用于指示一个PDSCH扰码序列，用于对PDSCH的传输比特进行加扰，从而减小各个PDSCH之间的干扰，所述PDSCH扰码ID可以用于第j个CORESET组调度的所有CC或BWP，或者说，所述第j个CORESET组调度的各个CC(BWP)中PDSCH都对应相同的PDSCH扰码ID，第j个CORESET组可以是M个CORESET组中的任何一个CORESET组。
可选实施方式六
本可选实施方式用于说明M个TRP传输的CORESET中没有配置高 层参数索引，或者大于1个CORESET，但有的TRP只有一个CC，那么这个TRP对应的这个CC的默认CORESET组的默认值问题。
本可选实施方式以M大于或者等于2个TRP为例说明，每个TRP可以通过载波聚合技术同时在多个CC传输PDSCH，比如每个TRP至少包括一个CC。这里包括大于1个的CORESET组。
在一次传输中，通过高层信令在第j个TRP中只用了一个CC传输数据。而高层信令配置了M个CORESET，则第j个TRP中用于传输数据的CC对应的CORESET组默认为CORESET组0，或高层索引值最小的CORESET组，这里，第j个TRP可以是所述M个TRP中的任何一个TRP。
在一次传输中，通过高层信令在第j个TRP中只用了K个CC传输数据。而高层信令配置了M个CORESET，则第j个TRP中用于传输数据的CC对应的CORESET组默认为CORESET组0至CORESET组K，或高层索引值最小的K个CORESET组，这里，第j个TRP可以是所述M个TRP中的任何一个TRP，K为小于M的正整数。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开各个实施例的方法。
