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(PhysicalDownlinkSharedChannel，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(PhysicalDownlinkControl Channel，物理下行控制信道)以及上行的控制 信道PUCCH(PhysicalUplinkControl Channel，物理上行控制信道)和数据信道PUSCH(PhysicalUplinkSharedChannel，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增强方式都是针对单一的TRP而言的，在多TRP场景下无法适用。

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：
表1
Figure PCTCN2020119602-appb-000001
Figure PCTCN2020119602-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。
另外，目前在重复传输PUSCH时，需要确定对应的RV(Redundancy Version，冗余版本)序列。对RV序列的确定方式例如表2所示：
表2
Figure PCTCN2020119602-appb-000003
对应上述的重复类型A传输方式，RV序列直接映射在所有传输时机上，基站发送DCI(Downlink Control Information，下行控制信息)，并通过DCI的RV信息域来指示RV序列的初始值。例如，DCI中的RV信息域为2比特，比特值为10，则对应表2中初始值为2的RV序列2、3、1、0。
对应上述的重复类型B传输方式，RV序列直接映射在所有实际传输时机上，基站同样发送DCI(Downlink Control Information，下行控制信 息)，并通过DCI的RV信息域来指示RV序列的初始值。
为了在重复传输PUSCH时支持多TPR场景，需要考虑不同的RV传输参数和不同的传输时机之间的映射，但是目前的方案中并未涉及。
为了解决上述问题，本公开提供了一种信道传输方案，可以在重复传输PUSCH时，应用RV参数的分配来支持多TRP传输。
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，确定至少一个基础RV序列与用于发送物理上行数据信道PUSCH的多个备选传输时机之间的映射关系。
在步骤202中，根据所述至少一个基础RV序列，确定所述多个备选传输时机中的每个备选传输时机对应的实际RV序列。
在本公开实施例中，实际RV序列是指根据相应的备选传输时机对应的基础RV序列进行循环映射得到的用于发送PUSCH的RV序列。例如，基础RV序列为0、2、3、1，实际RV序列可以是表2中的任意一个序列循环映射得到的RV序列，例如对应的RV序列值对应4次传输配置的情况可以为2、3、1、0或1、0、2、3。
在步骤203中，在多个目标传输时机上，分别基于相应的目标传输时机对应的所述实际RV序列，重复发送所述PUSCH的数据块。
上述实施例中，终端可以确定至少一个基础RV序列与用于发送PUSCH的多个备选传输时机之间的映射关系。根据至少一个基站RV序列，来确定每个备选传输时机对应的实际RV序列，从而在多个目标传输时机上，分别基于相应的目标传输时机对应的所述实际RV序列，重复发送所述PUSCH的数据块。本公开实现了重复传输PUSCH的同时，应用RV参数的分配来支持多TRP传输的目的，提高了数据传输的可靠性。
在一可选实施例中，针对上述步骤201，在确定映射关系时，可以根据基站发送的第一信令来确定，或者可以根据协议中预定义的设置，来确 定该映射关系。其中，第一信令可以是高层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，本公开对此不作限定。
上述实施例中，可以由基站配置该映射关系，或者在协议中预定义该映射关系，实现简便，可用性高。
在一可选实施例中，可以采用以下方式中的任意一种确定该映射关系。
第一种方式，根据对应基站不同发送和接收点TRP接收的不同波束指示信息与所述多个备选传输时机之间的第一对应关系，确定该映射关系。
参照图3所示，图3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201可以包括：
在步骤201-11中，确定对应基站不同发送和接收点TRP接收的不同波束指示信息与所述多个备选传输时机之间的第一对应关系。
其中，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。在本公开实施例中，波束指示信息可以包括spatial Relation Info(空间关系信息)，或者包括UL(Up Link，上行)TCI(Transmission Configuration Indicator，传输配置指示)state(状态)信息。
在步骤201-12中，根据所述不同波束指示信息对应的基础RV序列和所述第一对应关系，确定所述映射关系。
在本公开实施例中，不同波束指示信息可以对应相同的基础RV序列或不同的基础RV序列，终端根据不同波束指示信息对应的基础RV序列和上述的第一对应关系，可以确定至少一个基础RV序列与用于发送物理上行数据信道PUSCH的多个备选传输时机之间的映射关系。
上述实施例中，可以根据上述不同波束指示信息与多个备选传输时机之间的第一对应关系来确定该映射关系，实现简便，可用性高。
在一可选实施例中，参照图4所示，图4是根据图3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202-1中，将所述多个备选传输时机划分为多组。
其中，每组备选传输时机对应相同的波束指示信息。例如，多个备选传输时机包括两组备选传输时机，第一组备选传输时机对应波束指示信息TCI-1，第二组备选传输时机对应波束指示信息TCI-2。
在步骤202-2中，确定所述每组备选传输时机所对应的一个基础RV序列。
在本公开实施例中，每组备选传输时机可以对应一个基础RV序列，而多组备选传输时机可以对应相同或不同的基础RV序列。在本公开实施例中，可以由基站通过第二信令将每组备选传输时机对应的基础RV序列告知终端，或者在协议中预定义每组备选传输时机对应的基础RV序列。
例如，上述两组备选传输时机可以对应相同的一组基础RV序列，该序列为{0、2、3、1}。或者上述两组备选传输时机可以对应不同的两组基础RV序列，例如第一组备选传输时机对应基础RV序列0、2、3、1，第二组备选传输时机对应基础RV序列0、3、0、3，两个基础RV序列不同。
在步骤202-3中，确定所述每组备选传输时机所对应的所述实际RV序列的初始值或序列偏移值。
在本公开实施例中，可以直接确定所述每组备选传输时机所对应的所述实际RV序列的初始值，该初始值可以是基础RV序列中的一个值，表示实际RV序列从基础序列中开始循环的值。例如，基础RV序列为{0、2、1、3}，初始值为2，说明首个实际RV序列值为2，后续实际RV序列依次按照基础RV序列进行循环映射得到2，1，3，0，2，…。
或者终端可以确定每组备选传输时机所对应的所述实际RV序列的序列偏移值。其中，所述序列偏移值是所述每组备选传输时机相对于所述基础RV序列进行循环映射的RV序列起始位置。例如，基础RV序列为0、2、1、3，序列偏移值为3，默认偏移参考点为RV序列的一个值，则说明实际RV序列为基础RV序列的第一个RV序列值的起始值为3，后续实际RV序列依次按照基础序列进行循环映射得到3，0，2，1，3，…。。
在步骤202-4中，根据所述每组备选传输时机所对应的基础RV序列、 以及所述实际RV序列的初始值或所述序列偏移值，确定所述每组备选传输时机对应的多个实际RV序列。
例如，所述基础RV序列为0、2、1、3，实际RV序列为基础RV序列的第一个RV序列值的初始值为1，则后续实际RV序列依次按照基础序列进行循环映射得到1，3，0，2，1，…。
再例如，所述基础RV序列为0、2、1、3，序列偏移值为2，默认偏移参考点为RV序列的一个值，则说明实际RV序列为基础RV序列的第一个RV序列值的起始值为1，则后续实际RV序列依次按照基础序列进行循环映射得到1，3，0，2，1，…。上述实施例中，可以根据上述映射关系和至少一个基础RV序列，确定每个备选传输时机对应的实际RV序列，以便后续在多个目标传输时机上重复传输PUSCH。实现了重复传输PUSCH的同时，应用RV参数的分配来支持多TRP传输的目的，提高了数据传输的可靠性。
在一可选实施例中，针对上述步骤202-3可以采用以下方式实现：
根据基站发送的下行控制指令DCI所包括的指定信息域，确定所述每组备选传输时机所对应的实际RV序列的所述初始值或所述序列偏移值。
在本公开实施例中，可以通过DCI(Downlink Control Information，下行控制指令)中所包括的指定信息域将所述每组备选传输时机所对应的实际RV序列的所述初始值或所述序列偏移值告知终端。其中，指定信息域可以采用DCI中的RV域。
现有的DCI所包括的RV域包括2比特，只能针对一个波束指示信息对应的实际RV序列的初始值。
在一个示例中，可以扩展DCI的RV域，通过该RV域分别独立指示所述每组备选传输时机所对应的所述实际RV序列的初始值。
例如，有两组备选传输时机，则RV域可以扩展到4比特，前2比特用于指示第一组备选传输时机对应的实际RV序列的初始值，后2比特用于指示第二组备选传输时机对应的实际RV序列的初始值。
以两组备选传输时机对应相同的基础序列0、2、3、1为例，RV域的比特值为1001，说明第一组备选传输时机对应的实际RV序列的初始值为2，第二组备选传输时机对应的实际RV序列的初始值为1。
在另一个示例中，也可以不扩展RV域，RV域用于指示所述每组备选传输时机所对应的所述实际RV序列的初始值或所述序列偏移值关联的关联信息的对应码点RV codepoint。
可选地，可以预先确定RV codepoint与RV序列的初始值之间的第二对应关系，例如表3所示。
表3
RV codepoint RV1序列的初始值 RV2序列的初始值
0 0 2
1 1 3
2 2 0
3 3 1
基站可以通过DCI的RV域发送2比特的值，假设为10，终端根据表3可以确定数值2对应的是第一组备选传输时机对应的实际RV序列的初始值为2，第二组备选传输时机对应的实际RV序列的初始值为0。
或者，终端可以预先确定RV codepoint与序列偏移值之间的第三对应关系，例如表4所示。
表4
Figure PCTCN2020119602-appb-000004
Figure PCTCN2020119602-appb-000005
基站仍然可以通过DCI的RV域发送2比特的值，假设也为10，终端根据表4确定数值2对应的是第一组备选传输时机对应的实际RV序列的序列偏移为2，第二组备选传输时机对应的实际RV序列的序列偏移为0。相应地，基础序列如果都是0、2、3、1，那么第一组备选传输时机对应的首个实际RV序列为3、1、0、2，后续时机RV序列依次循环，第二组备选传输时机对应的首个实际RV序列为0、2、3、1，后续时机RV序列依次循环。
在本公开实施例中，表3、表4中的第二对应关系和第三对应关系可以由基站通过第三信令配置，或者在协议中预定义。其中，第三信令可以是RRC信令或MAC信令。
在另一个示例中，RV域还可以用于每组备选传输时机中相对于第一波束指示信息的实际RV序列中第一RV序列的初始值。其中，所述第一波束指示信息对应的RV序列为所述第一RV序列。
指定信息域用于指示所述每组备选传输时机中相对于第一波束指示信息的实际RV序列中第一RV序列的初始值的情况下，可以确定每组备选传输时机所对应的实际RV序列中其他RV序列的初始值相对于所述第一RV序列的初始值的偏移值。进一步地，基站可以根据所述第一RV序列的初始值和所述偏移值，分别确定所述其他RV序列的初始值。其中，所述偏移值是指其他RV序列的初始值相对于第一RV序列的初始值的偏移值，该偏移值可以由基站通过第四信令进行配置，或者在协议中预定义，其中第四信令可以是RRC信令或MAC信令。
例如，第一RV序列的初始值为RV1，根据第四信令或协议预配置的方式可以确定上述偏移值offset，例如根据公式RV2＝mod(RV1+offset，4)得到其他RV序列的初始值。
在一可选实施例中，上述方案中多组备选传输时机对应的是相同的一个基础RV序列，如果多组备选传输时机对应不同的基础RV序列，其方式可以为：
预先通过第二信令将多个基础RV序列告知终端，例如，基础RV序列为[RV1、RV2]，通过扩展DCI的RV域的方式，可以分别指示两组备选传输时机分别对应不同基础序列的初始值，例如RV域的比特值为0010，则第一组备选传输时机对应的是RV1中的初始值0，第二组备选传输时机对应的是RV2中的初始值2。
如果不扩展DCI的RV域，那么可以通过第三信令或协议预定义的方式确定表3或表4。终端根据RV域的值，查询表3或表4，可以确定不同组的备选传输时机分别对应的实际RV序列的初始值或序列偏移值。假设RV1为{0，2，3，1]，RV2是{0，3，0，3}，DCI的RV域的值为01，则根据表3可以得到第一组备选传输时机对应的实际RV序列的初始值为1，即首个实际RV序列为1、0、2、3。而第二组备选传输时机对应的实际RV序列的初始值为3，即首个实际RV序列为3、0、3、0。
根据表4确定序列偏移值的方式与上述方式雷同，在此不再赘述。
在一可选实施例中，对应上述的重复类型A传输方式，多个备选传输时机可以包括K1个名义传输时机。
其中，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。
如果K1个名义传输时机中存在第一传输时机，则所述多个目标传输时机包括多个第二传输时机，其中，第一传输时机是无法进行上行PUSCH发送的传输时机，所述多个第二传输时机是所述K1个名义传输时机中可以进行上行PUSCH发送的传输时机。
同样针对上述的重复类型A传输方式，多个备选传输时机可以直接包括K1’个实际传输时机；其中，所述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。
进一步地，多个目标传输时机包括所述K1’个实际传输时机。
对应上述的重复类型B传输方式，所述多个备选传输时机可以包括K2’个实际传输时机上；其中，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。
相应的，多个目标传输时机包括所述多个第二实际传输时机；其中。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传输的传输时机。
同样对应上述的重复类型B传输方式，所述多个备选传输时机可以包括K2”个实际传输时机；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。
进一步地，多个目标传输时机包括所述K2”个实际传输时机。
上述实施例中，终端可以根据不同波束指示信息和多个备选传输时机之间的对应关系，来确定至少一个基础RV序列与多个备选传输时机的映射关系，从而确定所述多个备选传输时机中的每个备选传输时机对应的实际RV序列。进一步地，终端可以在多个目标传输时机上，分别基于相应的目标传输时机对应的所述实际RV序列，重复发送所述PUSCH的数据块。实现了重复传输PUSCH的同时，应用RV参数的分配来支持多TRP传输的目的，提高了数据传输的可靠性。
在一可选实施例中，还可以采用以下方式来确定上述映射关系。
第二种方式，不区分不同波束指示信息与多个备选传输时机之间的第一对应关系，直接确定至少一个基础RV序列与用于发送PUSCH的所有备 选传输时机之间的所述映射关系。
相应地，多个备选传输时机可以包括所有名义传输时机，应地，多个目标传输时机则包括所有名义传输时机中可以进行上行PUSCH传输的所有实际传输时机。
或者，多个备选传输时机包括可以进行上行PUSCH传输的所有实际传输时机，多个目标传输时机也包括所有时机传输时机。
上述实施例中，可以不考虑波束指示信息与备选传输时机之间的第一对应关系，直接进行基础RV序列与多个备选传传输时机的映射。同样实现了重复传输PUSCH的同时，应用RV参数的分配来支持多TRP传输的目的，提高了数据传输的可靠性。
