Description

信道传输方法及装置、存储介质 技术领域
本公开涉及通信领域，尤其涉及信道传输方法及装置、存储介质。
背景技术
为了改善小区边缘的覆盖，在服务小区内提供更为均衡的服务质量，多点协作在NR(New Radio，新空口)系统中仍然是一种重要的技术手段。
从网络形态角度考虑，以大量的分布式接入点结合基带集中处理的方式来进行的网络部署，将更加有利于提供均衡的用户体验速率，并且显著的降低越区切换带来的时延和信令开销。随着频段的升高，从保证网络覆盖的角度出发，也需要相对密集的接入点部署。而在高频段，随着有源天线设备集成度的提高，将更加倾向于采用模块化的有源天线阵列。每个TRP(Transmission and Receiving Points，发送和接收点)的天线阵可以被分为若干相对独立的天线面板，因此整个阵面的形态和端口数都可以随部署场景与业务需求进行灵活的调整。而天线面板或TRP之间也可以由光纤连接，进行更为灵活的分布式部署。在毫米波波段，随着波长的减小，人体或车辆等障碍物所产生的阻挡效应将更为显著。这种情况下，从保障链路连接鲁棒性的角度出发，也可以利用多个TRP或PANEL(面板)之间的协作，从多个角度的多个波束进行传输/接收，从而降低阻挡效应带来的不利影响。
在R16研究阶段，基于下行多TRP或PANEL间的多点协作传输技术的应用，对PDSCH(PhysicalDownlink SharedChannel，物理下行数据信道)进行了传输增强。由于数据传输包括上下行信道的调度反馈，因此在URLLC(Ultra-relaible and Low Latency Communication，极可靠低时延通信)的研究中，只对下行数据信道增强不能保证业务性能。因此在R17(Release 17，版本17)的研究中，继续对下行控制信道PDCCH(PhysicalDownlink Control Channel，物理下行控制信道)以及上行的控制 信道PUCCH(PhysicalUplink Control Channel，物理上行控制信道)和数据信道PUSCH(PhysicalUplink SharedChannel，物理下行数据信道)进行增强。
以PUSCH为例，可以采用重复传输PUSCH的方式来进行增强，目前的PUSCH传输方式都是针对单一的TRP而言的，在多TRP场景下无法适用。

在介绍本公开提供的信道传输方案之前，先介绍一下R15和R16中的两种PUSCH增强方式。
第一种增强方式，R15中所采用的重复类型A传输方式。
该重复类型A传输方式是针对时隙级别而言的，Slot Aggregation(时隙聚合)PUSCH传输方式。例如图1A所示，一个PUSCH在连续的K个传输时机(nominal repetition)上重复传输，图1A中K的取值为2。从起始时隙的第S个符号上开始传输，每个传输时机会持续L个符号，图1A中L的取值为4。
需要主要的是(S+L)不超过时隙边界，例如一个时隙包括14个时间符号，那么(S+L)不超过14。
该重复类型A传输方式不适用于时延要求低且可靠性要求高的业务。
第二种增强方式，R16中所采用的重复类型B传输方式。
为了适用于时延要求低且可靠性要求高的业务，R16提出了以mini-slot(迷你时隙)为单位的PUSCH重复传输方式，即重复类型B传输方式，允许PUSCH的重复传输跨时隙进行，从而进一步降低时延。
在时域上，一个PUSCH在起始时隙的第S个符号上开始传输，连续不间断的发送K个传输时机，每个传输时机都连续占用L个符号，例如图1B所示。
同时，在重复类型B传输方式中，(S+L)可以跨越时隙边界，在传输时机出现跨时隙边界的情况下，传输时机被重新分割，对应得到实际传输时机(actural repetition)K’。例如图1C和图1D所示。
在图1C中，第3个传输时机由于跨越了时隙边界，被时隙边界再次划分为2个实际传输时机，即在图1C中，PUSCH的传输时机K为4，但实际传输时机K’为5。
在图1D中，只有1个传输时机，该传输时机由于跨越了时隙边界，被时隙边界再次划分为2个实际传输时机，即在图1D中，PUSCH的传输时机K为1，但实际传输时机K’为2。
基站可以通过SFI(Slot Format Indicator，时隙格式指示符)指示半静态的Flexible(灵活)时间符号为动态的上行符号或动态下行符号，因此半静态Flexible时间符号对PUSCH可能是可用符号(即Flexible时间符号为上行信号，可以用于进行PUSCH传输)，也可能是不可用符号(即Flexible时间符号为下行信号，不可以用于进行PUSCH传输)。其中有不可用的时间符号时，需要drop(丢弃)不可用的时间符号，在剩余的可用符号上传输PUSCH。即对于整个传输而言，时隙L×K可以表示PUSCH传输的时间窗口大小，如果在该时间窗口中出现某个时间符号无法进行上行传输，那么该时间符号是不能够传输PUSCH的，需要将该传输时机drop(丢弃)掉，在其他的传输时机上传输PUSCH。
上述的重复类型A传输方式和重复类型B传输方式对应的取值如表1所示：

Figure PCTCN2020119604-appb-000002
在上述的重复类型A传输方式和重复类型B传输方式中，其适用于单个RTP场景，不支持终端利用多TRP技术重复传输PUSCH来提高数据传输可靠性。
为了解决上述问题，本公开提供了一种信道传输方案，可以基于多TRP场景重复传输PUSCH，提高了数据传输的可靠性。
本公开实施例提供了一种信道传输方法，可以用于终端，参照图2所示，图2是根据一实施例示出的一种信道传输方法流程图，该方法可以包括以下步骤：
在步骤201中，终端按照预先确定的映射方式，将对应基站不同发送和接收点TRP接收的不同波束指示信息，分别映射到多个备选传输时机上。
在本公开实施例中，波束指示信息是用于进行上行数据信道PUSCH发送的波束相关信息。其中，波束指示信息可以包括spatial Relation Info(空间关系信息)，或者包括UL(UpLink，上行)TCI(Transmission Configuration Indicator，传输配置指示)state(状态)信息。
在步骤202中，基于多个目标传输时机分别对应的所述波束指示信息，在所述多个目标传输时机上，重复传输物理上行数据信道PUSCH上的传输块或只单独发送对应的解调参考信号DMRS。
上述实施例中，终端可以按照预先确定的映射方式，将对应基站不同 TRP接收的波束指示信息，分别映射到多个备选传输时机上。进一步地，多个目标传输时机分别对应的所述波束指示信息，在所述多个目标传输时机上，重复传输物理上行数据信道PUSCH上的传输块或只单独发送对应的解调参考信号DMRS。实现了在多TRP场景下对PUSCH进行增强的目的，提高了数据传输的可靠性。
在一可选实施例中，对应上述的重复类型A传输方式，上述步骤201可以采用以下方式将不同波束指示信息映射到多个备选传时机上：
第一种方式，终端按照预先确定的映射方式，将所述不同波束指示信息分别映射到K1个名义传输时机上。
其中，K1个名义传输时机分别位于不同的时隙内，所述K1个名义传输时机在各时隙内的起始符号位置相同，且在各时隙内的持续符号数目相同。
即在采用上述的重复类型A传输方式进行PUSCH增强的情况下，可以将不同波束指示信息分别映射到K1个名义传输时机上。例如图3所示，将不同的TCI分别映射到4个名义传输时机Rep#1至Rep#4上，TCI-1、TCI-2是不同的波束指示信息。
对应于此种方式，如果K1个名义传输时机中存在无法进行上行PUSCH传输的第一传输时机，那么参照图4所示，图4是根据图2所示实施例示出的另一种信道传输方法流程图，步骤202可以包括：
在步骤202-11中，响应于确定所述K1个名义传输时机中存在第一传输时机，将所述K1个名义传输时机中的多个第二传输时机作为所述多个目标传输时机。
在本公开实施例中，第一传输时机是指所述K1个名义传输时机中无法进行上行PUSCH传输的传输时机，所述多个第二传输时机是指所述K1个名义传输时机中可以进行上行PUSCH传输的多个传输时机。
其中，第一传输时机可以指重复类型A传输方式中，由于资源分配导致该传输时机中某个符号被配置为下行符号，或者第一实际传输时机还可 以指由于其他情况导致无法进行上行PUSCH传输的传输时机。从而无法进行上行PUSCH传输的传输时机。多个第二传输时机则是重复类型A传输方式下，K1个名义传输时机中不存在符号配置冲突的多个传输时机。
在本公开实施例中，如果K1个名义传输时机中存在上述的第一传输时机，那么可以将多个第二传输时机作为所述多个目标传输时机。
在步骤202-12中，基于所述多个第二传输时机分别对应的所述波束指示信息，在所述多个第二传输时机上，重复传输所述PUSCH上的传输块。
在本公开实施例中，可以根据多个第二传输时机分别对应的所述波束指示信息，确定至少包括波束方向的波束相关信息后，在多个第二传输时机上，重复传输所述PUSCH上的传输块。
例如图3所示，如果第三个名义传输时机为无法进行上行PUSCH传输的第一传输时机，则终端是在第1、2、4个传输时机上分别基于对应的波束指示信息重复传输PUSCH上的传输快。
上述实施例中，K1个名义传输时机中如果存在无法进行上行PUSCH传输的第一传输时机，终端可以在除了第一传输时机的多个第二传输时机上重复传输PUSCH上的传输块，实现了在多TRP场景下对PUSCH进行增强的目的，提高了数据传输的可靠性。
或者对应上述方式一，参照图5所示，图5是根据图2所示实施例示出的另一种信道传输方法流程图，步骤202可以包括：
在步骤202-21中，响应于确定所述K1个名义传输时机中存在第一传输时机，将所述K1个名义传输时机作为所述多个目标传输时机。
在本公开实施例中，如果K1个名义传输时机中存在无法进行上行PUSCH传输的第一传输时机，那么终端仍可以将所有的K1个名义传输时机作为多个目标传输时机。
在步骤202-22中，基于多个第二传输时机分别对应的所述波束指示信息，在所述多个第二传输时机上，重复传输所述PUSCH上的传输块，以及在所述第一传输时机上，只单独发送对应的解调参考信号DMRS。
在本公开实施例中，终端可以在多个第二传输时机上，重复传输PUSCH上的传输块，并且在第一传输时机上，只通过第一个符号单独发送对应的DMRS(Demodulation Reference Signal，解调参考信号)，以便基站可以根据DMRS，更好的进行信道估计。
同样例如图3所示，可以在第1、2、4个传输时机上重复传输PUSCH上的数据块，在第3个传输时机上传输DMRS。
上述实施例中，如果K1个名义传输时机中存在无法进行上行PUSCH传输的第一传输时机，那么可以在第一传输时机上只单独发送DMRS，在除了第一传输时机之外的多个第二传输时机上重复传输PUSCH上的传输块。同样实现了在多TRP场景下对PUSCH进行增强的目的，提高了数据传输的可靠性的目的，且提高了信道估计质量。
在一可选实施例中，针对上述步骤202-22中的在第一传输时机上，只通过第一个符号单独发送对应的解调参考信号DMRS的过程，可以采用以下方案：
在一个示例中，可以根据映射到所述第一传输时机上的所述波束指示信息，在所述第一传输时机上只单独发送对应的解调参考信号DMRS。
在本公开实施例中，由于之前将不同波束指示信息映射到了K1个名义传输时机上，第一传输时机也存在对应的波束指示信息，那么可以直接根据映射到所述第一传输时机上的所述波束指示信息，在所述第一传输时机上只单独发送对应的解调参考信号DMRS。
在另一个示例中，根据第三传输时机对应的所述波束指示信息，确定所述第一传输时机对应的所述波束指示信息后，在所述第一传输时机上只单独发送对应的解调参考信号DMRS。
在本公开实施例中，第三传输时机是所述K1个名义传输时机中与所述第一传输时机相邻的传输时机。继第三传输时机可以是第一传输时机之前的一个传输时机或之后的一个传输时机。第一传输时机对应的所述波束指示信息可以与第三传输时机对应的波束指示信息相同或不同，本公开对 此不作限定。
在根据第三传输时机对应的所述波束指示信息，确定所述第一传输时机对应的所述波束指示信息后，按照第一传输时机对应的波束指示信息，在所述第一传输时机上只单独发送对应的解调参考信号DMRS。
上述实施例中，实现了在无法进行上行PUSCH传输的第一传输时机上只单独发送对应的解调参考信号DMRS的目的，提高了信道估计质量，可用性高。
在一可选实施例中，对应上述的重复类型A传输方式，上述步骤201还可以采用以下方式将不同波束指示信息映射到多个备选传时机上：
第二种方式，终端按照预先确定的映射方式，将所述不同波束指示信息分别映射到K1’个实际传输时机。
在本公开实施例中，K1’个实际传输时机是K1个名义传输时机中可以进行上行PUSCH传输的传输时机，所述K1个名义传输时机分别位于不同的时隙内，所述K1个名义传输时机在各时隙内的起始符号位置相同，且在各时隙内的持续符号数目相同。
图3中的第1、2、4个传输时机可以作为K1’个实际传输时机，其映射方式可以例如图6所示。
对应上述第二种方式，参照图7所示，图7是根据图2所示实施例示出的另一种信道传输方法流程图，步骤202可以包括：
在步骤202-31中，将所述K1’个实际传输时机作为所述多个目标传输时机。
在本公开实施例中，可以直接将K1’个实际传输时机作为所述多个目标传输时机。
在步骤202-31中，基于所述K1’个实际传输时机分别对应的所述波束指示信息，在所述K1’个实际传输时机上，重复传输所述PUSCH上的传输块。
上述实施例中，可以将不同波束指示方向直接映射到K1’个实际传输 时机上，并将K1’个实际传输时机作为多个目标传输时机，重复传输所述PUSCH上的传输块。实现了在多TRP场景下对PUSCH进行增强的目的，提高了数据传输的可靠性的目的。
在一可选实施例中，对应上述的重复类型B传输方式，上述步骤201可以采用以下方式将不同波束指示信息映射到多个备选传时机上：
第三种方式，终端按照预先确定的映射方式，将所述不同波束指示信息分别映射到K2个名义传输时机上。
其中，K2个名义传输时机是背对背连续分配的传输时机，其映射方式例如图8所示。
对应于上述第三种方式，参照图9所示，图9是根据图2所示实施例示出的另一种信道传输方法流程图，步骤202可以包括：
在步骤202-41中，响应于所述K2个名义传输时机被划分为K2’个实际传输时机，且所述K2’个实际传输时机中存在第一实际传输时机，将多个第二实际传输时机作为所述多个目标传输时机。
在本公开实施例中，由于K2个名义传输时机可以跨时隙，因此可能存在被时隙边界划分出的K2’个实际传输时机。或者某个名义传输时机被自身所包括的下行符号划分为两个实际传输时机。例如K2个名义传输时机中的第m个名义传输时机中的第d个符号被配置为了下行符号，那么第d个符号之前的符号属于一个实际传输时机，第d个符号之后的符号属于另一个实际传输时机。
其中，所述第一实际传输时机是上述K2’个实际传输时机中无法进行上行PUSCH传输的传输时机，所述多个第二实际传输时机是所述K2’个实际传输时机中可以进行上行PUSCH传输的多个传输时机。
需要说明的是，第一实际传输时机可以指K2’个实际传输时机中，由于任一符号被配置为下行符号，导致无法进行上行PUSCH的传输时机。或者第一实际传输时机可以指K2’个实际传输时机中，由于被(时隙或下行信号)划分后导致所包括的符号数目太少，使得有效编码率过高，基站 侧即使接收到该时机传输时机发送的信息也无法成功解码的传输时机。或者第一实际传输时机还可以指由于其他情况导致无法进行上行PUSCH传输的传输时机。而多个第二实际传输时机则是可以进行上行PUSCH传输的多个传输时机。
在本公开实施例中，可以将多个第二实际传输时机作为所述多个目标传输时机。
在步骤202-42中，基于所述多个第二实际传输时机对应的所述波束指示信息，在所述多个第二实际传输时机上，重复传输所述PUSCH上的传输块。
例如图8所示，如果Rep#4-1属于无法进行上行PUSCH传输的第一实际传输时机，那么终端可以在Rep#1、Rep#2、Rep#3和Rep#4-2上分别根据波束指示信息TCI-1、TCI-2、TCI-1、TCI-2，重复传输PUSCH上的传输块。
上述实施例中，在K2’个实际传输时机中存在无法进行上行PUSCH传输的第一实际传输时机的情况下，可以只在多个第二实际传输时机上重复传输所述PUSCH上的传输块。实现了在多TRP场景下对PUSCH进行增强的目的，提高了数据传输的可靠性的目的。
或者对应于上述第三种方式，参照图10所示，图10是根据图2所示实施例示出的另一种信道传输方法流程图，步骤202可以包括：
在步骤202-51中，响应于所述K2个名义传输时机被划分为K2’个实际传输时机，且所述K2’中存在第一实际传输时机，将所述K2’个实际传输时机作为所述多个目标传输时机。
在本公开实施例中，如果K2个名义传输时机被划分为K2’个实际传输时机，且所述K2’中存在无法进行上行PUSCH传输的第一实际传输时机，那么仍然可以将K2’个实际传输时机作为所述多个目标传输时机。
在步骤202-52中，基于多个第二实际传输时机对应的所述波束指示信息，在所述多个第二实际传输时机上，重复传输所述PUSCH上的传输块， 以及在所述第一实际传输时机，只单独发送对应的解调参考信号DMRS。
在本公开实施例中，多个第二实际传输时机是所述K2’个实际传输时机中可以进行上行PUSCH传输的多个传输时机。
同样例如图8所示，终端可以在Rep#1、Rep#2、Rep#3和Rep#4-2上采用对应的波束指示信息，重复传输PUSCH上的传输块，以及在Rep#4-1上单独发送对应的解调参考信号DMRS。
上述实施例中，可以在多个多个第二实际传输时机上，重复传输所述PUSCH上的传输块，以及在所述第一实际传输时机，只单独发送对应的解调参考信号DMRS，从而在实现了在多TRP场景下对PUSCH进行增强的目的，提高了数据传输的可靠性的目的的同时，提高了信道估计质量。
在一可选实施例中，对应上述的重复类型B传输方式，上述步骤201可以采用以下方式将不同波束指示信息映射到多个备选传时机上：
第四种方式，终端按照预先确定的映射方式，将所述不同波束指示信息分别映射到K2’个实际传输时机上。
其中，K2’个实际传输时机是对K2个名义传输时机进行划分得到的多个实际传输时机，所述K2个名义传输时机是背对背连续分配的传输时机。该映射方式例如图11所示。
对应上述第四种方式，参照图12所示，图12是根据图2所示实施例示出的另一种信道传输方法流程图，步骤202可以包括：
在步骤202-61中，响应于确定所述K2’个实际传输时机中存在第一实际传输时机，将多个第二实际传输时机作为所述多个目标传输时机。
在本公开实施例中，所述第一实际传输时机是所述K2’个实际传输时机中无法进行上行PUSCH传输的传输时机，所述多个第二实际传输时机是所述K2’个实际传输时机中可以进行上行PUSCH传输的多个传输时机。在本公开实施例中，直接将多个第二实际传输时机作为所述多个目标传输时机。
在步骤202-62中，基于所述多个第二实际传输时机对应的所述波束指 示信息，在所述多个第二实际传输时机上，重复传输所述PUSCH上的传输块。
例如图11所示，终端可以在Rep#1、Rep#2、Rep#3和Rep#4-2上分别根据波束指示信息TCI-1、TCI-2、TCI-1、TCI-1，重复传输PUSCH上的传输块。
上述实施例中，可以在将不同波束指示信息映射到K2’个实际传输实际上的情况下，在确定所述K2’个实际传输时机中存在无法进行上行PUSCH传输的第一实际传输时机时，在可以进行上行PUSCH传输的多个第二实际传输时机上，重复传输所述PUSCH上的传输块。实现了在多TRP场景下对PUSCH进行增强的目的，提高了数据传输的可靠性的目的。
对应上述第四种方式，参照图13所示，图13是根据图2所示实施例示出的另一种信道传输方法流程图，步骤202可以包括：
在步骤202-71中，响应于确定所述K2’个实际传输时机中存在第一实际传输时机，将所述K2’个实际传输时机作为所述多个目标传输时机。
在本公开实施例中，即使K2’个实际传输时机中存在无法进行上行PUSCH传输的第一实际传输时机，也可以将K2’个实际传输时机作为所述多个目标传输时机。

其中，多个第二实际传输时机是所述K2’个实际传输时机中可以进行上行PUSCH传输的多个传输时机。

其中，所述K2”个实际传输时机是K2’个实际传输时机中，可以进行上行PUSCH传输的传输时机；所述K2’个实际传输时机是对K2个名义传输时机进行划分得到的实际传输时机；所述K2个名义传输时机是背对背分配的连续传输时机。其映射方式例如图14所示。

或者对应上述第五种方式，参照图16所示，图16是根据图2所示实施例示出的另一种信道传输方法流程图，步骤202可以包括：
在步骤202-91中，将所述K2’个实际传输时机作为多个目标传输时机。

例如图14所示，终端在Rep#1、Rep#2、Rep#3和Rep#4-2上根据波束指示信息TCI-1、TCI-2、TCI-1、TCI-2，重复传输PUSCH上的传输块，以及在Rep#4-1上，只单独发送对应的解调参考信号DMRS。
上述实施例中，在实现了在多TRP场景下对PUSCH进行增强的目的，提高了数据传输的可靠性的目的的同时，提高了信道估计质量。
在一可选实施例中，针对上述第三、第四和第五种方式，所述在所述第一实际传输时机上，只单独发送对应的解调参考信号DMRS的过程，可以采用以下方案。
在一个示例中，可以根据映射到所述第一实际传输时机上的所述波束指示信息，在所述第一实际传输时机上，只单独发送对应的解调参考信号DMRS。
其中，如果第一实际传输时机存在对应的波束指示信息，则直接按照映射到所述第一实际传输时机上的所述波束指示信息，在所述第一实际传输时机上，只单独发送对应的解调参考信号DMRS即可。
在另一个示例中，根据第三实际传输时机对应的所述波束指示信息，确定所述第一实际传输时机对应的波束指示信息后，在所述第一实际传输时机上，只单独发送对应的解调参考信号DMRS。
其中，第三实际传输时机是所述K2’个实际传输时机中与所述第一实际传输时机相邻的实际传输时机。例如第三实际传输时机可以是第一实际传输时机的前一个或后一个传输时机。第一实际传输时机对应的波束指示信息可以与第三实际传输时机对应的所述波束指示信息相同或不同。
上述实施例中，实现了在无法进行上行PUSCH传输的第一实际传输时机上只单独发送对应的解调参考信号DMRS的目的，提高了信道估计质量，可用性高。
在一可选实施例中，上述的映射方式可以由基站通过第一信令进行配置，其中第一信令可以包括但不限于高层的RRC(Radio Resource Control，无线资源控制)信令，或者MAC(Media Access Control Address，媒体范围控制地址)信令。
在另一个示例中，基站可以通过第二信令配置与映射方式对应的关联信息。其中，第二信令可以与第一信令相同或不同。
在另一个示例中，可以直接在协议中设置该映射方式。
具体地，步骤201可以包括以下任意一项：
第一种方式，将所述不同波束指示信息按照预设顺序循环映射到所述多个备选传输时机上。
终端按照映射方式，将所述不同波束指示信息按照预设顺序循环映射到K1个名义传输时机上，此时得到的映射结果例如图3所示。如果存在第一传输时机，则终端可以在Rep#1、Rep#2和Rep#4上，分别按照TCI-1、TCI-2、TCI-2指示的信息，重复传输PUSCH上的数据块。
或者终端按照映射方式，将所述不同波束指示信息按照预设顺序循环映射到K1’个名义传输时机上，得到的映射结果例如图6所示。终端可以在Rep#1、Rep#2和Rep#4上，分别按照TCI-1、TCI-2、TCI-1指示的信息，重复传输PUSCH上的数据块。
第二种方式，将所述不同波束指示信息重复指定次数后，按照预设顺序映射到所述多个备选传输时机上。
例如，指定次数为2，则可以将TCI1重复2次，TCI2重复两次后进行映射，终端可以在Rep#1、Rep#2、Rep#3和Rep#4上，分别按照TCI-1、TCI-1、TCI-2、TCI-2指示的信息，重复传输PUSCH上的数据块。
此种方式中，如果K1个名义传输时机中存在第一传输时机，则可以参照第一种方式的循环映射方式进行处理，在此不再赘述。
第三种方式，将所述不同波束指示信息按照预设PUSCH重复传输次数平均映射到所述多个备选传输时机上。
例如预设PUSCH重复传输次数为8，终端可以在前4个传输时机上，按照TCI-1指示的信息，重复传输PUSCH上的数据块。在后4个传输时机上，按照TCI-1指示的信息，重复传输PUSCH上的数据块。
此种方式中，如果K1个名义传输时机中存在第一传输时机，则可以参照第一种方式的循环映射方式进行处理，在此不再赘述。
第四种方式，根据预先确定的关联信息和不同波束指示信息之间的对 应关系，确定所述关联信息所指示的不同波束指示信息对应的映射顺序后，按照所述预设顺序将所述不同波束指示信息映射到所述多个备选传输时机上。
在一个示例中，关联信息可以采用比特位图的方式来标识。
例如K1＝4的情况下，关联信息包括1001，假设上述对应关系为1对应TCI2，0对应TCI1，则映射顺序为TCI2、TCI1、TCI1、TCI2。终端可以在Rep#1、Rep#2、Rep#3和Rep#4上，分别按照TCI-2、TCI-1、TCI-1、TCI-2指示的信息，重复传输PUSCH上的数据块。
此种方式中，如果K1个名义传输时机中存在第一传输时机，则可以参照第一种方式的循环映射方式进行处理，在此不再赘述。
上述的第一种方式至第四种方式，也可以应用于重复类型B传输方式，具体不再赘述。
在一可选实施例中，步骤201还可以包括：
第五种方式，终端按照所述映射方式，将所述不同波束指示信息分别映射到多个顺序排列的时隙上的所包含的所有目标传输时机上
在此种方式下，不区分传输时机，而是根据时隙进行映射。假设针对重复类型B传输方式，其映射方式例如图17所示，终端可以在Rep#1、Rep#2、Rep#3、Rep#4-2上，分别按照TCI-1、TCI-2、TCI-2、TCI-1指示的信息，重复传输PUSCH上的数据块。
上述实施例中，实现了在多TRP场景下对PUSCH进行增强的目的，提高了数据传输的可靠性。
