Description

一种通信方法和装置
相关申请的交叉引用
本公开要求在2019年12月26日提交中国专利局、申请号为201911368904.9、申请名称为“一种通信方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及通信技术领域，尤其涉及一种通信方法和装置。
背景技术
在现有的无线通信系统中例如长期演进(Long Term Evolution，LTE)系统、新空口(New Radio，NR)系统，上行信号的多输入输出(Multiple Inpit Multiple Output，MIMO)传输都只支持宽带预编码，不支持子带预编码。
例如，在基于码本的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)上行传输方案下，基站只能向用户设备(User Equipment，UE)指示宽带的上行探测参考信号(Sounding Reference Signal，SRS)资源、预编码矩阵和传输流数，UE在传输PUSCH时，在所有被调度的频域资源上使用相同的模拟波束赋形、预编码矩阵和传输流数。其中SRS资源可以通过下行控制信息(Downlink Control Information，DCI)中的SRS资源指示(SRS Resource Indicator)域或无线资源控制(Radio Resource Control，RRC)信令指示，预编码矩阵和传输流数可以通过DCI中的预编码信息和层数(Precoding information and number of layers)域或RRC信令指示。
再例如，在基于非码本的PUSCH上行传输方案下，基站向UE指示一个宽带的SRS资源，例如：通过DCI中的SRS资源指示域或RRC信令SRS资源指示。UE在传输PUSCH时，在所有被调度的频域资源上使用相同的模拟波束赋形、预编码矩阵和传输流数。
子带预编码可以带来频域选择性预编码增益，提高上行信号传输的性能。在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)NR系统的讨论过程中，曾考虑对于上行PUSCH引入子带预编码。
然而，在现有技术中，基站指示上行信号的子带预编码的方法，以及UE在子带预编码传输时如何确定上行信号在所分配资源上的预编码的方法尚未有具体的方案。

另外，在本公开实施例中，“示例的”一词用于表示作例子、例证或说明。本公开中被描述为“示例”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
本公开实施例中，信息(Information)，信号(Signal)，消息(Message)，信道(Channel)有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。“的(of)”，“相应的(Corresponding，Relevant)”和“对应的(Corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
本公开实施例描述的网络架构以及业务场景是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
本公开实施例既可以应用在传统的典型网络中，也可以应用在未来的以UE为中心(UE-centric)的网络中。UE-centric网络引入无小区(Non-cell)的网络架构，即在某个特定的区域内部署大量小站，构成一个超级小区(Hyper cell)，每个小站为Hyper cell的一个传输点(Transmission Point,TP)或传输接收点(Transmission and Reception Point,TRP)，并与一个集中控制器(Controller)相连。当UE在Hyper cell内移动时，网络侧设备时时为UE选择新的子簇(sub-cluster)为其服务，从而避免真正的小区切换，实现UE业务的连续性。其中，网络侧设备包括无线网络设备。或者是，在以UE为中心的网络中，多个网络侧设备，如小站，可以有独立的控制器，如分布式控制器，各小站能够独立调度用户，小站之间在长期上存在交互信息，使得在为UE提供协作服务时，也能够有一定的灵活性。
为便于理解本公开实施例，首先以图1中示出的通信系统为例详细说明适用于本公开实施例的通信系统。图1示出了适用于本公开实施例的通信方法的通信系统的示意图。如图1所示，该通信系统100包括网络设备102和终端设备106，网络设备102可配置有多个天线，终端设备也可配置有多个天线。可选地，该通信系统还可包括网络设备104，网络设备104也可配置有多个天线。

接下来介绍网络设备在上行资源中确定子带的方法以及为确定出的子带确定指示信息的方法。所述网络设备在上行资源中确定子带可以包括网络设备确定子带的频域。其中，实现方式可以包括以下几种。
第一种：
网络设备根据所述第一频域起始位置确定所述上行资源上的多个第二子带。
在一个可能的实现方式中，网络设备根据第一频域起始位置和子带宽度，将上行资源划分为多个第二子带。第一频域起始位置可以为所述多个第二子带中频率最低的子带的频域起始位置。例如，上行资源为物理资源块(Physical Resource Blocks，PRB)0-PRB14，第一频域起始位置为0，子带宽度为5。因此，终端设备可以将上行资源划分为多个第二子带分别为子带1：PRB0-PRB4，子带2：PRB5-PRB9，子带3：PRB10-PRB14。之后，网络设备确定第二子带中全部或部分第二子带的指示信息，并发送给终端设备。其中，指示信息包括网络设备确定的所述全部或部分第二子带对应的控制信息。此外，网络设备将为终端设备的上行信号分配的频域资源发送给终端设备。

可选的，子带宽度可以是预先确定的，或者还可以是协议规定的，又或者子带宽度可以是与终端设备协商得到的。

例如，终端设备的上行资源包括PRB0-PRB19，子带宽度为5个PRB，子带数量为4个。则网络设备根据第一频域起始位置PRB0和子带宽度可以确定子带1的频域起始位置为PRB0，子带2的频域起始位置为PRB5，子带3的频域起始位置为PRB10，子带4的频域起始位置为PRB15。继而确定出子带1：PRB0-PRB4，子带2：PRB5-PRB9，子带3：PRB10-PRB14，子带4：PRB15-PRB19。

另一种可能的实现方式中，第一频域起始位置可以是至少一个第一子带中频率最低的子带的起始位置。则，网络设备可以在上行资源上，根据第一频域起始位置、子带宽度以及子带数量确定出每一个第一子带。
例如，终端设备的上行资源包括PRB0-PRB19，子带宽度为5个PRB，子带数量为4个。则网络设备可以确定上行资源上的子带分别为子带1：PRB0-PRB4，子带2：PRB5-PRB9，子带3：PRB10-PRB14，子带4：PRB15-PRB19。
网络设备为至少一个第一子带中的全部或部分第一子带确定指示信息并发送给终端设备，其中，指示信息包括第一子带对应的控制信息，控制信息针对所述全部或部分第一子带分别指示。可选地，网络设备为全部或部分第一子带中的每个第一子带分别发送指示信息。
可选地，所述上行信号的指示信息中包括子带指示信息，子带指示信息与所述至少一个第一子带中的全部或部分子带存在映射关系，所述子带指示信息为指示所述上行信号在子带的传输参数和/或传输天线的指示信息。可选地，所述至少一个第一子带中全部或部分子带中的每个子带与子带指示信息具有一一对应关系。
在本公开实施例中，控制信息包括以下中的部分或全部：预编码矩阵指示信息、传输流数指示信息、空间相关信息、SRS资源指示信息、发送天线指示信息或天线面板panel指示信息。
可选地，所述上行信号的指示信息中包括子带指示信息，子带指示信息与所述至少一个第一子带存在映射关系，所述子带指示信息为指示所述上行信号在子带的传输参数和/或传输天线的指示信息。可选地，这种映射关系是一一对应关系。
通过上述方法1-方法4，网络设备可以在上行资源中确定出子带，并为确定出的子带确定指示信息发送给终端设备，以使得终端设备在传输上行信号时能够通过子带以及指示信息传输，提高上行信号的传输增益。
在介绍了网络设备在上行资源中确定子带以及为确定出的子带确定指示信息的方法之后，下面介绍终端设备在上行资源中确定用于传输上行信号的至少一个第一子带的方法。
其中，所述终端设备在上行资源中确定用于传输所述上行信号的至少一个第一子带可以包括所述终端设备确定出所述至少一个第一子带的子带大小、 所述终端设备确定出所述至少一个第一子带的子带数量、所述终端设备确定出所述至少一个第一子带的频域位置中的一个或多个。
在一种实现方式中，终端设备在上行资源中确定所述至少一个第一子带，可以包括确定所述至少一个第一子带的频域位置。实施时，所述终端设备可以在上行资源中确定一个第一频域起始位置，并根据第一频域起始位置确定所述至少一个第一子带的频域位置。第一频域起始位置是用来确定所述至少一个第一子带的一个频域起始位置。
具体的实现可以包括以下方法。
方法1：
终端设备可以根据第一频域起始位置确定上行资源上的多个第二子带，并在所述多个第二子带中确定所述至少一个第一子带。
一种可能的实现方式中，终端设备先根据第一频域起始位置在上行资源上确定多个第二子带。这里的上行资源可以是一个上行BWP的资源，可以是一个CC的资源，也可以是上行链路总的资源，也可以是所述上行信号所在的服务小区的上行资源。第一频域起始位置可以为所述多个第二子带中频率最低的子带的频域起始位置。终端设备在确定了上行资源的多个第二子带后，可以根据网络设备为所述上行信号分配的用于传输所述上行信号传输的频域资源，在多个第二子带中确定用于传输所述上行信号传输的频域资源对应的子带，作为所述至少一个第一子带。
可选地，终端接收网络设备为全部或部分第二子带发送的指示信息，所述指示信息包括网络设备确定的全部或部分第二子带对应的控制信息。可选地，网络设备为全部或部分第二子带中的各个第二子带分别发送指示信息。终端根据第一频域起始位置等可以确定出全部或部分第二子带对应的上行信号的传输参数和/或传输天线。并进一步根据这些频域资源对应的上行信号的传输参数和/或传输天线确定出所述至少一个子带上上行信号的传输参数和/或传输天线。
举例来说，一个上行BWP包括20个PRB，终端将这20个PRB分成了 4个子带，分别为子带1：PRB 0-4，子带2：PRB5-9，子带3：PRB 10-14，子带4：PRB15-19(其中PRB x表示标号为x的PRB，这里只是示意)，若网络设备为所述上行信号分配的频域资源为PRB 4-13,则这些PRB与子带2，3，4有重叠，终端确定出所述至少一个第一子带包括3个子带，分别为子带2：PRB5-9、子带3：PRB 10-14、子带4：PRB15-19。另一种确定方法是网络设备为所述上行信号分配的频域资源与上行资源被划分的子带重叠的部分即为所述至少一个第一子带。举例来说，一个上行BWP包括20个PRB，终端将这20个PRB分成了4个子带，分别为子带1：PRB 0-4，子带2：PRB5-9，子带3：PRB 10-14，子带4：PRB15-19(其中PRB x表示标号为x的PRB，这里只是示意)，若网络设备为所述上行信号分配的频域资源为PRB 4-13,则这些PRB与子带2，3，4有重叠，重叠的部分分别为PRB4，PRB5-9，PRB10-13，则终端确定出所述至少一个第一子带包括3个子带，分别为PRB4组成的子带，PRB5-9组成的子带和PRB10-13组成的子带。
又例如，网络设备给终端设备分配的上行资源包括PRB0-PRB28，并指示子带宽度为5个PRB。终端设备确定频率最低的子带的频域起始位置为PRB4，且子带宽度为5个PRB，则终端设备将上行资源划分为5个子带。其中，PRB4-PRB8为子带1，PRB9-PRB13为子带2，PRB14-PRB18为子带3，PRB19-PRB23为子带4，PRB24-PRB28为子带5。
网络设备向终端设备发送的用于传输上行信号的频域资源为PRB6-PRB18，则终端设备可以确定用于传输所述上行信号的至少一个第一子带为子带1、子带2、子带3。
可选地，所述上行信号的指示信息中包括子带指示信息，子带指示信息与所述至少一个第一子带中的全部或部分子带存在映射关系，所述子带指示信息为指示所述上行信号在子带的传输参数和/或传输天线的指示信息。可选地，所述至少一个第一子带中全部或部分子带中的每个子带与子带指示信息具有一一对应关系。
终端根据子带指示信息和子带的对应关系可以确定出这些子带对应的频 域资源上上行信号的传输参数和/或传输天线。并进一步根据这些频域资源对应的上行信号的传输参数和/或传输天线确定出所述至少一个子带上上行信号的传输参数和/或传输天线。
方法2：
终端设备根据第一频域起始位置、子带宽度和至少一个第一子带的子带数量确定所述至少一个第一子带。
在一种可能的是实现方式中，指示信息可以包括用于传输上行信号的至少一个第一子带对应的控制信息。可选地，终端设备可以根据所述指示信息包括的控制信息确定所述至少一个第一子带的数量。例如，控制信息的比特宽度与至少一个第一子带的数量成正比，则终端根据控制信息的比特宽度就可以确定出至少一个第一子带的数量。终端设备根据第一频域起始位置在上行资源中确定频率最低的子带的频域起始位置，在根据子带宽度和所述至少一个第一子带的数量，在上行资源中确定用于传输上行信号的至少一个第一子带。
可选的，终端根据第一频域起始位置确定出所述至少一个子带上上行信号的传输参数和/或传输天线。
需要说明的是，子带宽度可以是根据经验值预先确定的，或者还可以是网络设备指示的，或者还可以是网络设备与终端设备协商的，本公开不做具体限定。此外，前述至少一个第一子带的子带宽度可以完全相同。
可选地，所述子带宽度为所述至少一个第一子带的子带宽度(即子带占用频域资源的大小)。例如，假设所述子带宽度为4个PRB，所述至少一个第一子带的数量为4，第一频率起始位置为PRB 7，终端可以确定用于传输上行信号的至少一个第一子带分别为子带1：PRB7-PRB10，子带2：PRB11-PRB14，子带3：PRB15-PRB18，子带4：PRB19-PRB22。这与网络设备为所述上行信号分配的上行资源无关。
可选地，所述上行信号的指示信息中包括子带指示信息，子带指示信息与所述至少一个第一子带中的全部或部分子带存在映射关系，所述子带指示 信息为指示所述上行信号在子带的传输参数和/或传输天线的指示信息。可选地，所述至少一个第一子带中全部或部分子带中的每个子带与子带指示信息具有一一对应关系。
终端根据子带指示信息和子带的对应关系可以确定出所述至少一个子带上上行信号的传输参数和/或传输天线。
另一种可能的实现方式中，终端设备根据第一频域起始位置确定所述至少一个第一子带的子带起始位置，其中第一频域起始位置可以是第一子带中频率最低的子带的频域起始位置。终端设备首先确定一个子带大小，所述至少一个第一子带中任意一个子带的频域起始位置都等于第一频域起始位置加上子带大小的整数倍的偏移。即用Ns表示第一频域起始位置，则至少一个第一子带中任意一个子带的频域起始位置都等于Ns+M*N sub，其中M和N sub分别表示至少一个第一子带的子带数目和终端首先确定出的子带大小，M是正整数。
或者，终端设备首先确定一个子带大小，所述至少一个第一子带中除指定子带(例如第一个子带)外，其他子带的频域起始位置都等于第一频域起始位置加上子带大小的整数倍的偏移。可选地，第一个子带的频域起始位置等于网络设备为上行信号分配的频域资源的起始位置。可选地，最后一个子带的频域结束位置等于网络设备为上行信号分配的频域资源的最后一个资源的位置。
其中，指定子带可以是终端设备与网络设备预先约定的，或者还可以是协议约定的，又或者还可以是终端设备与网络设备协商得到的，又或者是终端设备根据约定的规则确定的。此外，指定子带还可以是网络设备指示的。
可选地，所述上行信号的指示信息中包括子带指示信息，子带指示信息与所述至少一个第一子带中的全部或部分子带存在映射关系，所述子带指示信息为指示所述上行信号在子带的传输参数和/或传输天线的指示信息。可选地，所述至少一个第一子带中全部或部分子带中的每个子带与子带指示信息具有一一对应关系。
终端根据子带指示信息和子带的对应关系可以确定出所述至少一个子带上上行信号的传输参数和/或传输天线。
在本公开实施例中，所述用于传输所述上行信号的频域资源可以携带在所述网络设备发送的配置信息中或者调度信息中。例如，用于所述上行信号传输的频域资源可以通过下行控制信息DCI中的频域资源分配域(Frequency domain resource assignment)指示。再例如，用于所述上行信号传输的频域资源可以通过RRC信令中的频域资源分配信令指示(Frequency Domain Allocation)。需要说明的是，子带大小(即子带包括的频域资源的数目，或者称为子带宽度)可以是根据经验值预先确定的，或者还可以是网络设备指示的，或者还可以是网络设备与终端设备协商的等。
方法3：
终端设备根据第一频域起始位置、子带宽度和网络设备为所述上行信号分配的频域资源确定所述至少一个第一子带。
一种可能的实现方式中，所述终端设备根据所述第一频域起始位置和子带宽度确定出所述至少一个第一子带。可选地，第一频域起始位置是所述至少一个第一子带中频率最低的子带的频域起始位置。
可选地，这里的子带大小是网络设备为所述上行信号配置的子带大小，并不是所述至少一个第一子带实际的大小。例如，网络设备为一个PUSCH配置的子带大小是4个PRB，但为该PUSCH分配的频域资源为18个PRB，假设第一频域起始位置是网络侧为该PUSCH分配的频域资源的起始位置N 0，一种可能是所述至少一个第一子带包括5个子带，其中一个子带的大小为2PRB，4个子带的大小为4PRB。
可选地，所述至少一个第一子带的任意一个子带的大小与网络设备为所述上行信号配置的子带大小相同。在这种情况下，基站为所述上行信号分配的频域资源需要是子带大小的整数倍。
另一种可能的实现方式中，所述终端设备根据第一频域起始位置和子带数量(或称为子带的数目)确定出所述至少一个第一子带。其中，第一频域 起始位置可以是第一子带中频率最低的子带的频域起始位置。所述子带个数可以是网络侧设备指示给终端设备的，也可以是终端按照预定义的规则确定的，或者网络侧设备和终端预先约定的(例如协议规定)。可选地，终端设备根据预定义的规则确定所述至少一个第一子带。例如，假设子带的个数为3，网络设备为一个PUSCH分配的频域资源为18个PRB，则终端确定出每个子带的PRB个数为18/3＝6，每个子带包括的PRB连续，则再根据第一频域起始位置，就可以确定出3个子带具体的频域位置。
可选的，所述第一频域起始位置是所述指示信息对应的频域资源的起始位置。其中，所述指示信息对应的频域资源在所述上行信号的频域资源上。举例来说，指示信息对应的频域资源为PRB12-PRB21，则所述第一频域起始位置则为PRB12。
又例如，终端设备上行信号的频域资源为PRB0-PRB24，指示信息对应的频域资源为PRB5-PRB8，则终端设备确定第一频域起始位置为PRB5。终端根据确定的第一频域起始位置和子带宽度在上行信号的频域资源上，确定至少一个第一子带，分别为子带1：PRB5-PRB9，子带2：PRB10-PRB14，子带3：PRB15-PRB19，子带4：PRB20-PRB24。
可选地，子带数量是终端设备根据网络设备为所述上行信号分配的频域资源包括的资源数和每个子带包括的子带宽度确定的。子带数量等于网络设备为上行信号分配的频域资源包括的资源数除以每个子带包括的频域资源数后得到数值的向上取整数。
可选地，子带数量是所述至少一个第一子带的子带的数量。
可选地，所述至少一个第一子带与所述上行信号的指示信息存在映射关系。这个映射关系可以是预先约定的，或者网络设备指示给终端的。
可选地，所述至少一个第一子带包括多个第二子带时，所述上行信号的指示信息中包括针对这多个第二子带中全部或部分子带的指示信息。可选地，所述上行信号的指示信息针对第二子带中全部或部分子带中的每个子带分别指示。即可以针对不同的子带指示不同的信息。
可选地，所述上行信号的指示信息中包括子带指示信息，子带指示信息与所述至少一个第一子带存在映射关系，所述子带指示信息为指示所述上行信号在子带的传输参数和/或传输天线的指示信息。可选地，所述至少一个第一子带中全部或部分子带中的每个子带与子带指示信息具有一一对应关系。
终端根据子带指示信息和子带的对应关系可以确定出所述至少一个子带上上行信号的传输参数和/或传输天线。
方法4：
终端设备根据所述第一频域起始位置、子带宽度确定所述上行资源上的多个第二子带，并在所述多个第二子带中确定所述至少一个第一子带。
在一种可能的实现方式中，第一频域起始位置是所述多个第二子带中频率最低的子带的频域起始位置。终端设备根据第一频域起始位置和子带宽度，确定上行资源上的每一个第二子带的频域起始位置。其中，所述第二子带中任意一个子带的频域起始位置都等于第一频域起始位置加上子带宽度的整数倍的偏移；或者，所述第二子带中除指定子带外的子带的频域起始位置都等于第一频域起始位置加上子带宽度的整数倍的偏移。继而终端设备可以根据各第二子带的频域起始位置和子带宽度确定出上行资源上的多个第二子带。
例如，终端设备的上行资源包括PRB0-PRB19，子带宽度为5个PRB。则终端设备可以确定上行资源上的每一个第二子带的频域起始位置分别为，PRB0、PRB5、PRB10以及PRB15。继而终端设备可以确定上行资源上的子带分别为子带1：PRB0-PRB4，子带2：PRB5-PRB9，子带3：PRB10-PRB14，子带4：PRB15-PRB19。
终端设备再根据网络设备分配的上行信号的频域资源，在多个第二子带中确定用于传输上行信号的至少一个第一子带。其中，所述终端设备根据所述网络设备为所述上行信号分配的频域资源，在所述多个第二子带中确定所述频域资源对应的子带，作为所述至少一个第一子带；或者，所述终端设备根据所述网络设备为所述上行信号分配的频域资源与所述多个第二子带的重叠频域确定所述至少一个第一子带。
另一种可能的实现方式中，第一频域起始位置是所述多个第二子带中频率最低的子带的频域起始位置。终端设备可以根据上行资源和子带宽度计算得出上行资源上第二子带的子带数量。继而终端设备根据第一频域起始位置、子带宽度和子带数量在上行资源中确定出多个第二子带。终端设备再根据网络设备分配的上行信号的频域资源，在多个第二子带中确定用于传输上行信号的至少一个第一子带。其中，所述终端设备根据所述网络设备为所述上行信号分配的频域资源，在所述多个第二子带中确定所述频域资源对应的子带，作为所述至少一个第一子带；或者，所述终端设备根据所述网络设备为所述上行信号分配的频域资源与所述多个第二子带的重叠频域确定所述至少一个第一子带。
例如终端设备的上行资源包括PRB0-PRB19，子带宽度为5个PRB。终端设备可以根据上行资源包括的PRB，以及子带宽度计算得到子带数量为5个。则终端设备可以确定上行资源上的子带分别为子带1：PRB0-PRB4，子带2：PRB5-PRB9，子带3：PRB10-PRB14，子带4：PRB15-PRB19。
通过上述方法1-方法4终端设备能够在上行资源中确定出用于传输上行信号的第一子带，并通过第一子带和第一子带对应的指示信息传输上行信号，能够提高上行信号的传输增益。

需要说明的是，针对前述多个第二子带，或者是针对前述至少一个第一子带，各子带包括的PRB可以是连续的。或者，所述多个第二子带或至少一个第一子带中存在包括非连续PRB的子带。
以下，不失一般性的以前述多个第二子带为例进行解释说明。举例来说，网络设备分配的终端设备的上行资源为PRB0-PRB10、以及PRB22-PRB35。终端设备将所述上行资源划分为多个第二子带，分别为子带1：PRB0-PRB4、子带2：PRB5-PRB9、子带3：PRB10、PRB22-PRB25、子带4：PRB26-PRB30、子带5：PRB31-PRB35。可以理解的是，前述多个第二子带中子带3包括的 PRB是非连续的，而子带1、子带2、子带4、子带5包括的PRB均为连续的。

如图7所示，其中横轴表示上行资源(PRB)，TPMIsub 1，TPMIsub 2，…,TPMIsub L表示指示信息包括的控制信息中的子带的预编码，它们的取值可以相同或不同。其中，第一频域起始位置为第二子带中频率最低的子带的频域起始位置，假设第一频域起始位置为PUSCH中用于传输上行信号的频域资源中编号最低的PRB，每个子带对应于多个连续的PRB。在本实施例中，子带的指示信息(预编码矩阵指示信息)与第二子带一一对应。终端设备可以根据第一频域起始位置和每个子带的子带宽度确定出多个第二子带，并根据子带的预编码矩阵指示信息确定出多个第二子带对应PRB的预编码矩阵。第一 子带为PUSCH中用于传输上行信号的频域资源中与第二子带重叠的PRB。在本实施例中，第m个第一子带跟第m个第二子带相同，m小于L，第L个第一子带是第L个第二子带的一部分。则终端可以确定出至少一个第一子带对应的预编码矩阵，则PUSCH传输使用的预编码为PUSCH中用于传输上行信号的各个PRB所在子带对应的预编码。
需要说明的是，在图7中每个子带的子带宽度是一样的，但可以理解的是本公开实施例提供的通信方法中各子带的子带宽度可以相同也可以不同。
实施例4：
终端设备无法根据网络设备的一次指示确定出PUSCH中用于传输上行信号的所有PRB的子带预编码信息。针对这些PRB，终端设备可以根据网络设备之前指示的子带预编码信息确定它们的预编码信息，或者使用宽带预编码作为它们的预编码。如图8所示，第一频域起始位置为第二子带中频率最低的子带的频域起始位置，假设第一频域起始位置为CRB 0的子载波0，子带预编码矩阵的指示信息与第二子带一一对应，终端设备只能确定出3个第二子带的子带预编码矩阵，则终端设备仅能确定PUSCH中用于传输上行信号的一部分PRB所在子带的预编码，终端设备需要采用其他方式确定其他PRB的预编码。例如，可以使用宽带预编码。
实施例5：
如图9所示，其中横向表示上行资源(PRB)，TPMIsub 1，TPMIsub 2，…,TPMIsub s表示指示信息包括的控制信息中的子带的预编码，它们的取值可以相同或不同。上行资源包括多个第二子带，其中第二子带的第一频域起始位置(第二子带频率最低的子带的频域起始位置)为初始BWP的PRB 0的子载波0。每个子带包括若干个连续的PRB，且各个子带的子带宽度相同。
网络设备发送的指示信息指示用于传输PUSCH的至少一个第一子带的预编码矩阵。第一子带的第一频域起始位置(第一子带频率最低的子带的频域起始位置)为PUSCH频域资源分配的最低频域位置。在本实施例中，第一子带与子带的预编码指示信息(控制)一一对应。终端设备根据控制信息可 以确定出各个第一子带的预编码矩阵，即可以确定出用于传输上行信号的各PRB的预编码。终端可以使用这些预编码矩阵传输PUSCH。
其中，BWP可以是PUSCH所在的BWP。
实施例6：
如图10所示，其中横轴表示上行资源，TPMIsub 1，TPMIsub 2，TPMIsub 3，TPMIsub 4表示指示信息包括的控制信息中的子带的预编码，它们的取值可以相同或不同。假设每个子带的子带宽度为4个PRB，频率最低的子带的频域起始位置为PUSCH中编号最低的PRB。
在本实施例中，第一频域起始位置为第一子带中频率最低的子带的频域起始位置，假设终端和网络设备约定为PUSCH被分配的频域资源的频率最低的PRB的频率最低的子载波(子载波0)。虽然第2个第一子带的PRB不连续，但在PUSCH被分配的频域资源中为VRB编号连续的PRB。第一子带与子带的预编码指示信息(控制信息)一一对应。假设网络设备为PUSCH分配的资源在频域上不连续(从PRB 3到PRB 9以及PRB 15到PRB 23)。终端设备根据第一频域起始位置可以确定出用于传输上行信号的至少一个第一子带(当然可以结合一些其他信息确定，例如第一子带的大小、第一子带的数量等)，根据控制信息可以确定出各个子带的预编码矩阵，则PUSCH传输使用的预编码为PUSCH中用于传输上行信号的各个PRB所在子带对应的预编码。
