Abstract

本申请公开了一种通信方法及装置，用于优化终端的发送波束的配置过程。本申请中网络设备通过第一信息，向终端指示目标上行资源，从而由终端配置目标上行资源对应的发送波束。由于第一对应关系中，属于同一个分组的上行资源对应同一个TRP，当目标上行资源为多个时，通过目标分组信息指示的多个目标上行资源关联至同一个TRP，因此可避免对于关联至不同的TRP的上行资源配置有相同的发送波束，以提高通信效率。

Description

一种通信方法及装置 技术领域
本申请涉及通信领域，特别涉及一种通信方法及装置。
背景技术
在高频通信系统中，为了克服路损，基站和终端通常都会使用具有方向性的、高增益的天线阵列形成模拟波束(或称波束)，用于通信。一般来说，可以通过主瓣方向和3dB的波束宽度来描述一个模拟波束的形状(beam pattern)。以上行通信为例，终端可朝向某个发送波束对应的方向进行信号发送，基站可根据某个接收波束的方向进行接收，当发送波束的方向和接收波束的方向对齐时，能够实现正常的上行通信。
目前，可由基站向终端配置多个上行资源，上行资源可用于终端发送上行信号。此外，还可由基站向终端配置每个上行资源对应的发送波束。在配置发送波束时，基站需要针对每一个上行资源，分别通过信令指示该上行资源对应的处于激活状态的空间关系，由于配置的上行资源可能有多个，因此目前在配置终端的发送波束时的信令开销较大，造成资源浪费。如果采用同一个信令来指示多个上行资源共同采用的发送波束，则可能造成多TRP传输场景下，与不同的TRP关联的上行资源配置有相同的发送波束，导致通信效率降低。
发明内容
本申请提供一种通信方法，用于优化发送波束的配置过程，以提高通信效率。
第一方面，本申请提供一种通信方法。该通信方法可由手机等终端或终端中的芯片执行。
以终端为例，根据该方法，终端可接收来自网络设备的第一信息，该第一信息包括目标分组信息。终端可根据第一对应关系，确定该目标分组信息对应的目标上行资源。其中，第一对应关系包括上行资源、分组信息以及传输接收点(transmission and reception point，TRP)三者之间的对应关系。第一对应关系中，属于同一个分组的上行资源对应同一个TRP，例如，同一个分组的全部上行资源均对应于同一个TRP。终端还可确定所述目标上行资源对应的发送波束，并根据所述发送波束，向所述网络设备发送信号。
其中，上行资源可以是物理上行控制信道(physical uplink control channel，PUCCH)资源(resource)、物理上行共享信道(physical uplink shared channel，PUSCH)资源或者、探测参考信号(sounding reference signal，SRS)资源等。
分组信息可以是上行资源的分组信息，分组信息可用于表示上行资源所属的分组。例如，若上行资源为PUCCH资源，则分组可以是PUCCH资源分组(PUCCH resource group)。TRP的信息可用于指示上行资源所关联的TRP。
上述第一对应关系中，属于同一个分组的上行资源对应于同一个TRP，或者说，属于同一个分组的上行资源不关联到不同的TRP。例如，属于同一个PUCCH资源分组的PUCCH资源不关联到不同的TRP(PUCCH resources in a same PUCCH resource group should not be associated with different TRPs)。
采用以上方法，可由网络设备通过第一信息，向终端指示目标上行资源，从而由终端 配置目标上行资源对应的发送波束。由于第一对应关系中，属于同一个分组的上行资源对应同一个TRP，当目标上行资源为多个时，通过目标分组信息指示的多个目标上行资源关联至同一个TRP，因此可避免对于关联至不同的TRP的上行资源配置有相同的发送波束，以提高通信效率。
在本申请中，分组信息例如上行资源的组标识。TRP的信息例如高层索引(higher layer index)或控制资源集合池索引(CORESET pool index)或控制资源集合索引，TRP与高层索引(或控制资源集合池索引)的取值之间一一对应。
示例性的，终端可根据所述发送波束，向所述目标上行资源对应的TRP发送所述信号。
可选地，上述第一对应关系中，每个分组信息可对应一个或多个上行资源(或者说，一个或多个上行资源对应于一个分组，或每个分组包含一个或多个上行资源)，每个TRP可对应一个或多个分组信息(或者说，一个或多个分组对应于一个TRP，或每个TRP对应于一个或多个分组的上行资源)。
示例性的，终端可从网络设备接收该第一对应关系。
此外，终端可从该网络设备接收第二信息，第二信息用于确定所述目标上行资源对应的空间关系中，处于激活状态的空间关系。终端可根据处于激活状态的空间关系，确定所述目标上行资源对应的发送波束。
上述第一信息以及所述第二信息可承载于同一个信令，以节省信令开销。例如，第三信息以及第四信息承载于波束指示信令。波束指示信令可以是媒体访问控制(media access control，MAC)-控制元素(control element，CE)消息或下行控制信息(download control information，DCI)。
第二方面，本申请实施例提供一种通信方法。该方法可由网络设备或网络设备中的芯片执行。其中，网络设备可包括接入网设备，如基站等。
以网络设备为例，根据该方法，可由网络设备向终端发送第一对应关系，该第一对应关系包括上行资源、分组信息以及TRP三者之间的对应关系，其中，属于同一个分组的上行资源对应同一个TRP。网络设备还可向终端发送第一信息，第一信息包括目标分组信息，所述目标分组信息用于终端确定目标上行资源，目标上行资源与目标分组信息对应。
上述第一对应关系中，所述第一对应关系中，一个或多个上行资源对应于一个分组，一个或多个分组对应于一个TRP。
示例性的，所述网络设备还可向终端发送第二信息，第二信息用于确定目标上行资源对应的空间关系中，处于激活状态的空间关系。
上述第一信息以及第二信息可承载于同一个信令。

第三方面，本申请提供一种通信方法。该通信方法可由手机等终端或终端中的芯片执行。
以终端为例，根据该方法，终端可接收来自网络设备的第三信息，该第三信息包括目标分组信息以及目标TRP的信息。终端根据第二对应关系，确定目标分组信息以及目标TRP的信息对应的目标上行资源。其中，第二对应关系为上行资源、分组信息以及TRP三者之间的对应关系。终端确定目标上行资源对应的发送波束，并根据所述发送波束，向网络设备发送信号。
采用该方法，可由网络设备通过第三信息，向终端指示目标上行资源，从而由终端配置目标上行资源对应的发送波束。并且，由于第三信息包括目标组标识以及目标TRP的信息，当目标上行资源为多个时，多个目标上行资源均关联到目标TRP，因此能够避免将关联至不同的TRP的上行资源配置为相同的发送波束，以提高通信效率。
应理解，以上第二对应关系可由终端从网络设备接收，或由协议定义，或预配置于终端。
在一种可能的示例中，终端可根据该发送波束，向目标TRP发送信号。
此外，终端还可从网络设备接收第四信息，该第四信息用于确定所述目标上行资源对应的空间关系中，处于激活状态的空间关系。例如，第四信息可包括处于激活状态的空间关系的标识和/或非处于激活状态的空间关系的标识。终端可根据处于激活状态的空间关系，确定所述目标上行资源对应的发送波束。
示例性的，以上第三信息以及第四信息可承载于同一信令，以节省信令开销。
第四方面，本申请实施例提供一种通信方法。该方法可由网络设备或网络设备中的芯片执行。其中，网络设备可包括接入网设备，如基站等。

采用以上方法，可由网络设备通过第五信息，向终端指示目标上行资源，从而由终端根据第三对应关系确定第五信息对应的目标上行资源。其中，当第三对应关系为上行资源与分组信息之间的对应关系，此时多个上行资源均关联到同一个TRP；当第三对应关系为上行资源与TRP之间的对应关系，第五信息为目标TRP的信息，因此目标上行资源均对应于目标TRP。从而可避免对于关联至不同的TRP的上行资源配置有相同的发送波束，以提高通信效率。
以上第三对应关系，可由终端从所述网络设备接收。示例性的，若第三对应关系为上 行资源与分组信息之间的对应关系，则终端可将第五信息确定为目标组信息。若第三对应关系为上行资源与TRP的信息之间的对应关系，则终端可将第五信息确定为目标TRP的信息。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。方法实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。
如图1所示，本申请实施例提供的通信方法可应用于无线通信系统，该无线通信系统可以包括终端101以及网络设备102。
应理解，以上无线通信系统既可适用于低频场景(sub 6G)，也可适用于高频场景(above6G)。无线通信系统的应用场景包括但不限于第五代系统、新无线(new radio，NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network，PLMN)系统等。
以上所示终端101可以是用户设备(user equipment，UE)、终端(terminal)、接入终端、 终端单元、终端站、移动台(mobile station，MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或终端设备等。该终端101可具备无线收发功能，其能够与一个或多个通信系统的一个或多个网络设备进行通信(如无线通信)，并接受网络设备提供的网络服务，这里的网络设备包括但不限于图示网络设备102。
其中，终端101可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端装置或者未来演进的PLMN网络中的终端装置等。
另外，终端101可以部署在陆地上，包括室内或室外、手持或车载；终端101也可以部署在水面上(如轮船等)；终端101还可以部署在空中(例如飞机、气球和卫星上等)。所述终端101具体可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。终端101也可以是具有通信模块的通信芯片，也可以是具有通信功能的车辆，或者车载设备(如车载通信装置，车载通信芯片)等。
网络设备102可以是接入网设备(或称接入网站点)。其中，接入网设备是指有提供网络接入功能的设备，如无线接入网(radio access network，RAN)基站等等。网络设备102具体可包括基站(base station，BS)，或包括基站以及用于控制基站的无线资源管理设备等。该网络设备102还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备102可以是可穿戴设备或车载设备。网络设备102也可以是具有通信模块的通信芯片。
比如，网络设备102包括但不限于：5G中的下一代基站(g nodeB，gNB)、LTE系统中的演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、CRAN系统下的无线控制器、基站控制器(base station controller，BSC)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseBand unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)或移动交换中心等。网络设备102还可包括未来6G或更新的移动通信系统中的基站。
基于图1所示架构，在进行上行传输时，网络设备102可为终端101配置上行资源，这些上行资源用于传输上行信号。此外，网络设备102还向终端101配置每个上行资源对应的SR，例如，针对每个上行资源配置一个或多个SR列表，每个SR列表可包括多个SR。网络设备102还可向终端101配置这些SR中处于激活状态的SR，这些处于激活状态的SR可用于确定发送上行信号所采用的发送波束。
示例性的，上行信号可用于承载于物理上行控制信道(physical uplink control channel，PUCCH)或物理上行共享信道(physical uplink shared channel，PUSCH)，或者，上行信号可包括探测参考信号(sounding reference signal，SRS)。
以PUCCH为例，网络设备102可通过无线资源控制(radio resource control，RRC)消息向终端101配置波束列表(或称SR列表)，其中，波束列表可包括多个PUCCH资源 以及PUCCH资源分别对应的SR，例如，包括PUCCH资源的标识与SR标识之间的对应关系。网络设备102还可通过媒体访问控制(media access control，MAC)-控制元素(control element，CE)消息或下行控制信息(download control information，DCI)，向终端101指示PUCCH资源对应的SR中处于激活状态的SR。以MAC-CE为例，该MAC-CE消息可携带PUCCH资源的标识，以及携带SR指示信息，用于指示处于激活状态的SR。终端101在接收到MAC-CE消息后，可根据PUCCH资源的标识确定可用的上行资源，并根据SR指示信息确定该PUCCH资源中处于激活状态的SR。后续在进行PUCCH发送时，终端101可通过这些处于激活状态的SR确定发送波束，并通过发送波束发送PUCCH。
示例性的，网络设备102可通过多个TRP与终端101之间进行通信，以提高传输效率，其中，多个TRP各自的空间位置是不同的。以图2为例，网络设备102可通过TRP#1以及TRP#2与终端101进行通信。以上行通信为例，网络设备102可通过TRP#1或TRP#2向终端101发送配置信息，用于配置上行资源，配置的上行资源可用于上行信息的传输。此后，终端101可根据网络设备102配置的上行资源，通过上行资源关联的TRP(如，TRP#1和/或TRP#2)，进行上行传输。
本申请提供一种通信方法，可在多TRP传输场景下，对网络设备102配置的上行资源中的一个或多个上行资源配置发送波束，同时，可确保不会针对关联到不同的TRP的多个上行资源配置相同的发送波束。
如图3所示，本申请实施例提供的通信方法的第一种实施例，可包括以下步骤：
S101：网络设备102向终端101发送第一信息，该第一信息包括目标分组信息。相应地，终端101接收第一信息。
S102：终端101根据第一对应关系，确定与目标分组信息对应的目标上行资源。
其中，第一对应关系包括上行资源、分组信息以及TRP三者之间的对应关系，其中，属于同一个分组的上行资源对应同一个TRP。或者换句话说，属于同一个分组的上行资源不关联到不同的TRP。
例如，属于同一个PUCCH资源分组的PUCCH资源不关联到不同的TRP(PUCCH resources in a same PUCCH resource group should not be associated with different TRPs)。
S103：终端101确定目标上行资源对应的发送波束。
S104：终端101根据发送波束，向网络设备102发送信号。具体的，若上行资源为PUCCH资源，则终端101可根据发送波束，向网络设备102发送控制信息，如上行控制信息(uplink control information，UCI)，该控制信息承载于PUCCH。若上行资源为PUSCH资源，则终端101可根据发送波束，向网络设备102发送上行数据，该上行数据承载于PUSCH。若上行资源为PUSCH资源，则终端101可根据发送波束，向网络设备102发送上行数据，该上行数据承载于PUSCH。此外，上行资源还可以是SRS的资源，则终端101可根据该发送波束发送SRS。
采用以上方法，可由网络设备102通过第一信息，向终端101指示目标上行资源，从而由终端101配置目标上行资源对应的发送波束。由于第一对应关系中，属于同一个分组的上行资源对应于同一个TRP，当目标上行资源为多个时，通过目标分组信息指示的多个目标上行资源关联至同一个TRP，因此可避免对于关联至不同的TRP的上行资源配置有相同的发送波束，以提高通信效率。
在本申请中，可通过上行资源的标识表示一个上行资源，例如，上行资源的标识可以 是网络设备102向终端101配置的上行资源的索引。
此外，分组信息可用于表示上行资源所属的分组。例如，若上行资源为PUCCH资源，则分组可以是PUCCH资源分组(PUCCH resource group)。示例性的，若上行资源的组标识相同，则表示上行资源属于同一个上行资源的分组。上述分组信息可包括组标识。
TRP的信息可以是上行资源关联的控制资源集合(control resource et，CORESET)(或称控制信道资源集合)的信息，例如CORESET资源池索引(CORESET pool index)，或称高层索引。
应理解，CORESET资源池索引的取值与TRP之间一一对应，因此若上行资源的CORESET资源池索引的取值相同，则表示上行资源关联于同一个TRP。例如，控制资源集合池索引“0”表示上行资源与TRP#1关联，控制资源集合池索引“1”表示上行资源与TRP#2关联。相应地，第一信息中，目标分组信息可包括目标组标识，目标组标识可以是第一对应关系包括的多个组标识中的一个；目标TRP的信息可包括目标控制资源集合池索引，目标控制资源集合池索引可以是第一对应关系包括的多个控制资源集合池索引中的一个。
此外，本申请中上行资源的分组数目的最大取值，可取决于是否支持多TRP传输，例如，单TRP传输时，可将上行资源分为两组，多TRP传输时，最多可以将上行资源分为四组。原因在于，目前协议最大支持2个TRP和4个上行资源分组，在这种情况下，一种最合理的设计是令一个组内的上行资源使用同一个发波束，同时每个TRP可以关联两个分组，也就是说，终端101朝向每个TRP发送时有两个分组的发送波束可用。
以上第一对应关系可由表1表示，其中，表1为上行资源的标识、组标识以及控制资源集合池索引之间的对应关系，其中，上行资源的标识可用于表示上行资源，组标识可用于表示分组信息，控制资源集合池索引可用于表示TRP的信息。其中，表1中以8个上行资源为例进行说明，实际实施中网络设备102可能配置其他数量的上行资源，例如，大于8个上行资源。
示例性的，上行资源的分组数目的最大取值取决于是否支持多TRP传输，例如，单TRP传输时，可将上行资源分为两组，多TRP传输时，最多可以将上行资源分为四组。

表1
根据表1可知，属于同一个分组的上行资源，均关联到同一个TRP。例如，组标识“1”对应于上行资源的标识“1”以及“2”，因此组标识“1”表示的上行资源的分组包括上行资源“1”以及上行资源“2”。此外，上行资源的标识“1”以及“2”均对应于控制资源 集合池索引“0”，因此，上行资源1以及上行资源2均关联到同一个TRP，如TRP#1。
此外，根据表1可知，第一对应关系中还可包括第二上行资源，例如组标识为“2”的上行资源。其中，组标识为“1”的上行资源以及组标识为“2”的上行资源，均与控制资源集合池索引“0”对应，因此，这些上行资源均关联到同一个TRP。
示例性的，以上第一对应关系可由网络设备102配置并发送至终端101。例如，网络设备102可通过RRC消息向终端101发送第一对应关系。此外，第一对应关系也可由协议定义，或者采用预配置的方式确定。
下面举例几种第一对应关系的设置方式。
在一种具体的示例中，第一对应关系中，同一上行资源对应的组标识与TRP的信息满足以下公式：
N 0modK＝M 0；(公式一)
其中，N 0表示上行资源的组标识的取值，K为TRP数目，M 0为上行资源的组标识的TRP的信息。mod表示求模运算。
例如，当TRP数目为2时，其中，TRP#1对应的TRP的信息为“0”，TRP#2对应的TRP的信息为“1”。若上行资源对应的组标识为“1”，则根据公式一，1mod 2＝1，因此该上行资源对应的TRP的信息为“1”，该上行资源关联的TRP为TRP#1。若上行资源对应的组标识为“2”，则根据公式一，2mod 2＝0，因此该上行资源对应的TRP的信息为“0”，该上行资源关联的TRP为TRP#2。
在另一种具体的示例中，同一上行资源对应的组标识与TRP的信息满足以下公式：
N 0modK+L＝M 0；(公式一)
其中，N 0表示上行资源的组标识的取值，K为TRP数目，M 0为上行资源的组标识的TRP的信息，L表示偏移值，L为整数。mod表示求模运算。
此外，第一对应关系中，上行资源的组标识可以由与该上行资源相关的信息确定。
一种具体的示例中，组标识可以由上行资源标识确定。例如，组标识取上行资源的标识(或索引)对分组数目求模后的余数。
另一种具体的示例中，组标识可以由上行资源关联的下行控制信道资源集合(CORESET)的标识确定。例如，上行资源关联于CORESET S(S为该CORESET的标识)，则上行资源的组标识可以是S’，S＝S’；或者，S＝S’+S 0，S 0为偏移值，S 0为整数。
另外，组标识可以由TRP的信息和上行资源的标识联合确定。例如，控制资源集合池索引作为组标识的第一比特位，并根据上行资源的标识的奇偶，确定组标识的第二比特位，其中，1表示奇数，0表示偶数，两个比特位对应的十进制数值为上行资源的组标识。
在接收到第一信息后，终端101可根据第一对应关系确定目标上行资源。以表1为例，若第一信息表示的目标组标识为“1”，则终端101可根据表1确定目标上行资源的标识为“1”和“2”。
在一种可能的示例中，网络设备102还可向终端101发送第二信息，该第二信息用于指示发送波束。具体的，第二信息可用于确定目标上行资源对应的空间关系中，处于激活状态的空间关系，该处于激活状态的空间关系可用于确定目标上行资源对应的发送波束。
示例性的，网络设备102可向终端101配置每个上行资源对应的空间关系列表，该空间关系列表可包括k个空间关系的索引，以表示上行资源对应的k个空间关系，k为正整数。第二信息可通过k个二进制比特值指示每个索引对应的空间关系是否处于激活状态， 其中，每个比特位可记为Si。例如，Si＝1，表示第i个空间关系处于激活状态，Si＝0表示第i个空间关系未处于激活状态，其中，i＝1、2、…、k。又例如，Si＝1，表示第i+1个空间关系处于激活状态，Si＝0表示第i+1个空间关系未处于激活状态，其中，i＝0、2、…、k-1。第二信息也可通过长度为N的二进制比特流标识k个空间关系的索引。例如
Figure PCTCN2019116812-appb-000002
如果N＝4，0010表示第2个空间关系处于激活状态，或者0010表示第2+1个空间关系处于激活状态。应理解，本申请中的SR列表可以是针对终端101工作的每个载波分量(carrier component，CC)的每个BWP配置的，则该SR列表适用于每个CC的每个BWP；或者，SR列表可以是针对终端101工作的一个或多个CC配置的；或者，SR列表可以是针对终端101工作的一个CC的多个BWP配置的。从而可对上行资源的空间关系进行多粒度的灵活配置。
此外，第二信息可包括处于激活状态的空间关系的索引，终端101即可根据这些处于激活状态的空间关系确定发送波束；或者，第二信息可包括非处于激活状态的空间关系的索引，终端101可根据这些非处于激活状态的空间关系，确定空间关系列表中的其他空间关系处于激活状态，并根据处于激活状态的空间关系确定发送波束。
应理解，以上第二信息可用于确定一组处于激活状态的空间关系，据此可针对目标上行资源配置该组处于激活状态的空间关系。当目标上行资源为多个时，可针对该多个目标上行资源配置相同的发送波束。
在一种具体的示例中，上述第一信息以及第二信息可承载于同一波束指示信令。示例性的，该波束指示信令可以是MAC-CE消息或DCI。
以MAC-CE消息为例，如图4所示，字段“组信息(grouping info)”可用于携带第一信息。字段“空间关系信息”可用于携带第二信息。此外，图4中的字段“R”表示预留(reserved)字段。例如，字段“R”为取值为0的比特。波束指示信令还可包括服务小区(serving cell)标识、带宽部分(bandwidth part，BWP)标识，用于指示该波束指示信令所适用的小区和带宽范围。
从而基于图4所示信令，终端101可根据第一信息以及第二信息更新目标上行资源的空间关系列表，进而可在S103中可根据更新后的空间关系列表确定目标上行资源对应的发送波束。后续在S104中，当终端101发送上行信号时，即可根据发送波束进行发送。
可选的，网络设备102还可通过图4A所示的波束指示信令，指示终端101更新目标上行资源的SR，以实现终端101的发送波束的配置。其中，目标上行资源的数量可以为多个，因此可节省配置多个上行资源的发送波束时的信令开销。图4A所述的波束指示信令可以是一个MAC-CE消息。
如图4A所示，字段“Pi”(即P0、P1、P2……等)可用于指示需要更新空间关系的上行资源。其中，Pi与第i个或第i+1个上行资源对应(或者说，Pi与标识为i或i+1的上行资源对应)，Pi的取值用于表示是否需要更新该上行资源的空间关系，i＝0、1、2、…。更新是指，终端按照第二信息，设置目标上行资源对应的空间关系中，处于激活状态的空间关系。
示例性的，若Pi＝1，则表示第i个或第i+1个上行资源的空间关系信息需要根据第二信息进行更新，例如，P1＝1，则表示需要更新第1个上行资源(如标识为“1”的上行资源)的空间关系。若Pi＝0，则表示第i个或第i+1个上行资源的空间关系信息不需要根据第二信息进行更新，例如，P1＝1，则表示不需要更新第1个上行资源(如标识为“1”的 上行资源)的空间关系。此外，图4A中的字段“空间关系信息”可用于携带第二信息，具体可参照图4中的字段“空间关系信息”。此外，图4A中的字段“R”表示预留字段。例如，字段“R”为取值为0的比特。图4A所示的波束指示信令还可包括服务小区标识、带宽部分标识，用于指示该波束指示信令所适用的小区和带宽范围。
可选的，Pi＝1的所有上行资源可关联到同一个TRP，因此不会将分别属于不同TRP的上行资源的发送波束配置为相同的发送波束。
此外，Pi＝1的所有上行资源配置的空间关系信息相同(或者说，字段“空间关系信息”携带一个第二信息，终端101可根据该第二信息，更新Pi＝1的所有上行资源的空间关系)，以便针对多个上行资源配置相同的发送波束，提高配置效率。
此外，波束指示信令还可携带服务小区组标识，用于指示一个或多个服务小区组，每个服务小区组可包括一个或多个服务小区。例如，如图4或图4A所示的MAC-CE消息中还可以包括服务小区组标识。终端101可根据服务小区组标识确定服务小区组，并根据第二信息，更新该服务小区组中的一个或多个服务小区内，特定的上行资源分组内的上行资源的SR，其中，这些特定的上行资源分组根据第一信息确定。确定特定的上行资源分组的方式，可参照本申请提供的根据第一信息确定上行资源分组的任一方式。从而可提高配置发送波束的效率。
采用以上第二种实施例，可由终端101根据第一对应关系以及来自网络设备102的第一信息确定目标上行资源，并配置目标上行资源的发送波束。其中，第一对应关系中包括上行资源、分组信息以及TRP三者之间的对应关系，并且该实施例中，属于同一个分组的多个上行资源应关联到同一个TRP。第一信息可包括目标分组信息。由于第一对应关系中属于同一个分组的多个上行资源关联到同一个TRP，因此终端101根据第一对应关系以及第一信息所确定的目标上行资源均关联到同一TRP。后续在确定目标上行资源的发送波束时，终端101可将关联到同一TRP的目标上行资源的发送波束配置为相同的发送波束，能够避免将多个分别关联到不同TRP的上行资源的发送波束配置为相同的发送波束，以提高通信效率。
如图5所示，本申请实施例提供的通信方法的第二种实施例，可包括以下步骤：
S201：网络设备102向终端101发送第三信息，该第三信息包括目标分组信息以及目标TRP的信息。相应地，终端101接收第三信息。
S202：终端101根据第二对应关系，确定与目标分组信息以及目标TRP的信息对应的目标上行资源。
其中，第二对应关系为上行资源、分组信息以及TRP三者之间的对应关系。本申请中，分组信息可用于指示上行资源的分组。TRP的信息用于区分上行资源所关联的TRP。
应理解，第二对应关系中的上行资源包括该目标上行资源，分组信息包括该目标分组信息，TRP包括该目标TRP。
S203：终端101确定目标上行资源对应的发送波束。
S204：终端101根据发送波束，向网络设备102发送信号。
采用以上方法，可由网络设备102通过第三信息，向终端101指示目标上行资源，从而由终端101配置目标上行资源对应的发送波束。并且，由于第三信息包括目标组标识以及目标TRP的信息，当目标上行资源为多个时，多个目标上行资源均关联到目标TRP，避免关联至不同的TRP的上行资源配置有相同的发送波束，以提高通信效率。
以上第二对应关系可由表2表示，其中，表2为上行资源的标识、组标识以及高层索引之间的对应关系。其中，表2中以16个上行资源为例进行说明，实际实施中网络设备102可能配置其他数量的上行资源，例如，大于16个上行资源。

表2
示例性的，以上第二对应关系可由网络设备102配置并发送至终端101。例如，网络设备102可通过RRC消息向终端101发送第二对应关系。此外，第二对应关系也可由协议定义，或者采用预配置的方式确定。
在接收到第三信息后，终端101可根据第二对应关系确定目标上行资源。以表2为例，若第三信息表示的目标组标识为“1”、高层索引为“0”，则终端101可根据表2确定目标上行资源的标识为“1”和“3”。
在一种可能的示例中，网络设备102还可向终端101发送第四信息，第四信息可用于指示发送波束。具体的，第四信息可用于确定目标上行资源对应的空间关系中，处于激活状态的空间关系，该处于激活状态的空间关系可用于确定目标上行资源对应的发送波束。
具体的，第四信息可用于指示上行资源对应的空间关系列表中，每个空间关系是否处于激活状态，或者，用于指示空间关系列表中处于激活状态的空间关系，或者，用于指示空间关系列表中非处于激活状态的空间关系。以上第四信息的具体配置方式，可参照第一种实施例中关于第二信息的介绍。
为节约信令开销，以上第三信息以及第四信息可承载于同一个信令。
示例性的，第三信息以及第四信息可承载于波束指示信令。该波束指示信令可以是MAC-CE消息或DCI。
以MAC-CE消息为例，如图4所示，字段“组信息”可用于携带第三信息。字段“空间关系标识”可用于携带第四信息。从而基于图4所示信令，终端101可根据第三信息以 及第四信息更新目标上行资源的空间关系列表，进而可在S203中可根据更新后的空间关系列表确定目标上行资源对应的发送波束。后续在S204中，当终端101发送上行信号时，即可根据发送波束进行发送。
采用以上第一种实施例，可由终端101根据第二对应关系以及来自网络设备102的第三信息确定目标上行资源，并配置目标上行资源的发送波束。其中，第二对应关系中包括上行资源、分组信息以及TRP三者之间的对应关系。该实施例中，属于通过一个分组的多个上行资源可关联到同一个TRP，或者关联到多个不同TRP，不予进行限制。第三信息可包括目标分组信息以及目标TRP的信息。由于第二对应关系包括上行资源、分组信息以及TRP三者之间的对应关系，因此终端101根据第二对应关系以及第三信息所确定的目标上行资源均关联到同一TRP，即目标TRP。后续在确定目标上行资源的发送波束时，可将关联到同一TRP的目标上行资源的发送波束配置为相同的发送波束，能够避免将多个分别关联到不同TRP的上行资源的发送波束配置为相同的发送波束，以提高通信效率。
如图6所示，本申请实施例提供的通信方法的第三种实施例，可包括以下步骤：
S301：网络设备102向终端101发送目标分组信息。相应地，终端101接收目标分组信息。
S302：终端101根据上行资源以及分组信息之间的对应关系，确定与目标分组信息对应的目标上行资源。
该示例中，网络设备102不会针对终端101的上行资源配置关联的TRP。例如，在单TRP传输场景中，可将多个上行资源划分到不同的分组，或者换句话说，全部上行资源分组中的上行资源均关联至同一个TRP。
S303：终端101确定目标上行资源对应的发送波束。
S304：终端101根据发送波束，向网络设备102发送信号。
采用以上方法，可由网络设备102通过目标分组信息，向终端101指示目标上行资源，从而由终端101根据上行资源以及分组信息之间的对应关系，确定目标分组信息对应的目标上行资源，并配置目标上行资源对应的发送波束。当目标上行资源为多个时，通过目标分组信息指示的多个目标上行资源不会关联不同的TRP，因此可避免对于关联至不同的TRP的上行资源配置有相同的发送波束，以提高通信效率。
以上上行资源以及分组信息之间的对应关系可由表3表示。其中，上行资源的标识可用于表示上行资源，组标识可用于表示上行资源的分组。其中，表3中以8个上行资源为例进行说明，实际实施中网络设备102可能配置其他数量的上行资源，例如，大于8个上行资源。

表3
在配置表3所示的上行资源以及分组信息之间的对应关系时，若终端101关联的TRP数量为1，则可将多个上行资源分为多组，每组上行资源所关联的TRP相同，因此可避免针对多个关联到不同TRP的上行资源配置相同的发送波束，以提高通信效率。
示例性的，以上上行资源以及分组信息之间的对应关系可由网络设备102配置并发送至终端101。例如，网络设备102可通过RRC消息向终端101发送上行资源以及分组信息之间的对应关系。此外，上行资源以及分组信息之间的对应关系也可由协议定义，或者采用预配置的方式确定。
在一种可能的示例中，网络设备102还可向终端101发送波束指示信息，该波束指示信息用于指示发送波束。具体的，波束指示信息可用于确定目标上行资源对应的空间关系中，处于激活状态的空间关系，该处于激活状态的空间关系可用于确定目标上行资源对应的发送波束。
具体的，波束指示信息可用于指示上行资源对应的空间关系列表中，每个空间关系是否处于激活状态，或者，用于指示空间关系列表中处于激活状态的空间关系，或者，用于指示空间关系列表中非处于激活状态的空间关系。以上波束指示信息的具体配置方式，可参照第一种实施例中关于第二信息的介绍。
在一种具体的示例中，上述目标分组信息以及波束指示信息可承载于同一波束指示信令。示例性的，该波束指示信令可以是MAC-CE消息或DCI。
以MAC-CE消息为例，如图4所示，字段“组信息”可用于携带目标分组信息。字段“空间关系标识”可用于携带波束指示信息。从而基于图4所示信令，终端101可根据目标分组信息以及波束指示信息更新目标上行资源的空间关系列表，进而可在S303中可根据更新后的空间关系列表确定目标上行资源对应的发送波束。后续在S304中，当终端101发送上行信号时，即可根据发送波束进行发送。
采用以上第三种实施例，可由终端101根据上行资源与分组信息之间的对应关系以及来自网络设备102的目标分组信息，确定目标上行资源，并配置目标上行资源的发送波束。其中，上行资源可关联至同一个TRP(或者说，终端101采用单TRP传输)，因此终端101根据第三对应关系以及目标分组信息所确定的目标上行资源均关联到同一TRP。
如图7所示，本申请实施例提供的通信方法的第四种实施例，可包括以下步骤：
S401：网络设备102向终端101发送目标TRP的信息，该目标TRP的信息包括目标TRP的信息。相应地，终端101接收目标TRP的信息。
S402：终端101根据上行资源以及TRP的信息之间的对应关系，确定与目标TRP的 信息对应的目标上行资源。

示例性的，以上上行资源以及TRP的信息之间的对应关系可由网络设备102配置并发送至终端101。例如，网络设备102可通过RRC消息向终端101发送该对应关系。此外，该对应关系也可由协议定义，或者采用预配置的方式确定。
在一种可能的示例中，网络设备102还可向终端101发送波束指示信息，该波束指示信息用于指示发送波束。具体的，波束指示信息可用于确定目标上行资源对应的空间关系中，处于激活状态的空间关系，该处于激活状态的空间关系可用于确定目标上行资源对应的发送波束。
具体的，波束指示信息可用于指示上行资源对应的空间关系列表中，每个空间关系是否处于激活状态，或者，用于指示空间关系列表中处于激活状态的空间关系，或者，用于指示空间关系列表中非处于激活状态的空间关系。以上波束指示信息的具体配置方式，可参照第一种实施例中关于第二信息的介绍。
在一种具体的示例中，上述目标TRP的信息以及波束指示信息可承载于同一波束指示信令。示例性的，该波束指示信令可以是MAC-CE消息或DCI。
以MAC-CE消息为例，如图4所示，字段“组信息”可用于携带目标TRP的信息。字段“空间关系标识”可用于携带波束指示信息。从而基于图4所示信令，终端101可根 据目标TRP的信息以及波束指示信息更新目标上行资源的空间关系列表，进而可在S303中可根据更新后的空间关系列表确定目标上行资源对应的发送波束。后续在S304中，当终端101发送上行信号时，即可根据发送波束进行发送。
采用以上第四种实施例，可由终端101根据上行资源以及TRP的信息之间的对应关系以及来自网络设备102的目标TRP的信息，确定目标上行资源，并配置目标上行资源的发送波束。由于该对应关系中包括上行资源与TRP的信息之间的对应关系，因此终端101根据该对应关系以及目标TRP的信息所确定的目标上行资源均关联到同一TRP(即目标TRP)。
在一种具体的实例中，以上第三种实施例以及第四种实施例可结合实施。例如，可由终端101向网络设备102选择执行第三种实施例所示方法或执行第四种实施例所示方法。示例性的，在第三种实施例所示方法执行之前，可由终端101向网络设备102发送指示信息，用于指示终端101是否支持采用第三种实施例所示方法配置发送波束。当终端101支持采用第三种实施例所示方法配置发送波束时，可执行图6所示步骤。此外，也可由终端101向网络设备102发送指示信息，用于指示终端101是否支持采用第四种实施例所示方法配置发送波束。当终端101支持采用第四种实施例所示方法配置发送波束时，可执行第四种实施例所示步骤。
示例性的，当终端101向网络设备102发送第一指示(如“0”比特)时，表示终端101支持采用第三种实施例所示流程。网络设备102可在接收第一指示后，向终端101发送目标分组信息，并执行第三种实施例所示流程。当终端101向网络设备102发送第二指示(如“1”比特)时，表示终端101支持采用第四种实施例所示流程。网络设备102可在接收第一指示后，向终端101发送目标TRP的信息，并执行第四种实施例所示流程。
此外，还可由网络设备102通过对应关系的配置，指示终端101采用第三种实施例或第四种实施例所示的流程配置发送波束。示例性的，当网络设备102向终端101配置的是上述上行资源与分组信息之间的对应关系时，则表示采用第三种实施例所示流程，后续网络设备102可向终端101发送目标分组信息，用于终端101确定目标上行资源；当网络设备102向终端101配置的是上述上行资源与TRP之间的对应关系时，则表示采用第四种实施例所示流程，后续网络设备102可向终端101发送目标TRP的信息，用于终端101确定目标上行资源。
示例性的，网络设备102可向终端101发送第五信息，用于终端101根据第三对应关系以及第五信息确定目标上行资源，并配置目标上行资源的发送波束。其中，若第三对应关系为上行资源与分组信息之间的对应关系，则所述第五信息包括目标分组信息，终端101可根据上述第三种实施例所述方法确定目标上行资源。或者，若第三对应关系为上行资源与TRP之间的对应关系，则所述第五信息包括目标TRP的信息，终端101可根据上述第四种实施例所述方法确定目标上行资源。
此外，当以上第三种实施例以及第四种实施例结合实施时，网络设备102可采用同一结构的波束指示信令，向终端101进行波束指示。以图4所示波束指示信令为例，若采用第三种实施例，或者说，若第三对应关系为上行资源与组标识之间的对应关系，则图4所示波束指示信令中的字段“组信息”可用于携带目标分组信息，终端101在解析该字段后，可按照上行资源与组标识之间的对应关系确定该目标分组信息对应的目标上行资源。若采用第四种实施例，或者说，若第三对应关系为上行资源与TRP的信息之间的对应关系，则 图4所示波束指示信令中的字段“组信息”可用于携带目标TRP的信息，终端101在解析该字段后，可按照上行资源与TRP的信息之间的对应关系确定该目标TRP的信息对应的目标上行资源。
此后，终端101还可根据来自网络设备102的第六信息，确定目标上行资源对应的空间关系中，处于激活状态的空间关系。该第六信息的设置方式，可参照上述第三终实施例或第四种中对于波束指示信息的说明。
如图8所示，本申请实施例提供的通信方法的第五种实施例，可包括以下步骤：
S501：网络设备102向终端101发送第七信息，该第七信息可包括第一上行资源的标识。相应地，终端101接收第七信息。
S502：终端101根据第四对应关系，确定与第一上行资源的标识对应的目标分组信息以及目标TRP的信息。
其中，第四对应关系包括上行资源、分组信息以及TRP三者之间的对应关系。应理解，第四对应关系中的上行资源包括该第一上行资源，分组信息包括该目标分组信息，TRP包括该目标TRP。
S503：终端101根据第四对应关系，确定与所述目标分组信息以及所述目标TRP的信息对应的目标上行资源。应理解，目标上行资源包括第一上行资源。
S504：终端101确定目标上行资源对应的发送波束。
S505：终端101根据发送波束，向网络设备102发送信号。
采用以上方法，可由网络设备102通过第七信息，向终端101指示第一上行资源，并由终端101根据该第一上行资源，确定目标上行资源，其中，目标上行资源与第一上行资源所对应的组标识和TRP的信息相同。因此当配置目标上行资源的发送波束时，能够避免对于关联至不同的TRP的上行资源配置有相同的发送波束，以提高通信效率。
以上第四对应关系可参照表5。其中，表5为上行资源的标识、组标识以及高层索引之间的对应关系，其中，上行资源的标识可用于表示上行资源，组标识可用于表示分组信息，高层索引可用于表示TRP的信息。其中，表5中以12个上行资源为例进行说明，实际实施中网络设备102可能配置其他数量的上行资源，例如，大于12个上行资源。
上行资源的标识 组标识 高层索引

9 1 0

表5
以表1为例，若第七信息指示的第一上行资源的标识为“1”，则终端101可根据表1确定目标组标识为“1”，目标高层索引为“0”，从而终端101进一步可根据目标组标识以及目标高层索引查询表5，确定目标上行资源的标识为“1”以及“9”。
示例性的，第四对应关系中上行资源的分组数目的最大取值取决于是否支持多TRP传输，例如，单TRP传输时，可将上行资源分为两组，多TRP传输时，最多可以将上行资源分为四组。
以上第四对应关系可由网络设备102配置并发送至终端101。例如，网络设备102可通过RRC消息向终端101发送第四对应关系。此外，第四对应关系也可由协议定义，或者采用预配置的方式确定。
在一种可能的示例中，网络设备102还可向终端101发送第八信息，该第八信息用于指示发送波束。具体的，第八信息可用于确定目标上行资源对应的空间关系中，处于激活状态的空间关系，该处于激活状态的空间关系可用于确定目标上行资源对应的发送波束。
具体的，第八信息可用于指示上行资源对应的空间关系列表中，每个空间关系是否处于激活状态，或者，用于指示空间关系列表中处于激活状态的空间关系，或者，用于指示空间关系列表中非处于激活状态的空间关系。以上第八信息的具体配置方式，可参照第一种实施例中关于第二信息的介绍。
在一种具体的示例中，上述第七信息以及第八信息可承载于同一波束指示信令。示例性的，该波束指示信令可以是MAC-CE消息或DCI。
以MAC-CE消息为例，如图4所示，字段“组信息”可用于携带第七信息。字段“空间关系标识”可用于携带第八信息。从而基于图4所示信令，终端101可根据第七信息以及第八信息更新目标上行资源的空间关系列表，进而可在S503中可根据更新后的空间关系列表确定目标上行资源对应的发送波束。后续在S504中，当终端101发送上行信号时，即可根据发送波束进行发送。
采用以上第五种实施例，可由终端101根据第四对应关系以及来自网络设备102的第就信息确定目标组标识以及目标TRP的信息，进一步根据目标组标识以及目标TRP的信 息查询第四对应关系确定目标上行资源，后续可配置目标上行资源的发送波束。该实施例中，第四对应关系中属于通过一个分组的多个上行资源可关联到同一个TRP，或者关联到多个不同TRP，不予进行限制。由于采用上述方法确定的目标上行资源均关联至目标TRP，因此终端101可将关联到目标TRP的目标上行资源的发送波束配置为相同的发送波束，可避免将多个分别关联到不同TRP的上行资源的发送波束配置为相同的发送波束，以提高通信效率。
