具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获 得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种PUSCH指示方法的示意流程图。本实施例所示的PUSCH指示方法可以适用于基站，所述基站包括但不限于4G基站、5G基站、6G基站。所述基站可以与作为用户设备的终端进行通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。在一个实施例中，所述终端可以是后续任一实施例所述PUSCH发送方法所适用的终端。
如图1所示，所述PUSCH指示方法可以包括以下步骤：
在步骤S101中，为终端配置功能为“码本”的一个或多个信道探测参考信号SRS(Sounding Reference Signal)资源集合，所述SRS资源集合中的SRS资源与波束相关信息相关联；
在步骤S102中，根据所述终端基于所述SRS资源发送的SRS确定用于上行协作传输的多个波束，以及每个所述波束对应的指示信息，其中，每个所述波束对应所述基站中不同的传输接收点TRP；
在步骤S103中，向所述终端发送多个所述指示信息，其中，所述指示信息用于指示所述终端确定用于上行协作传输的波束对应的波束相关信息，并基于所确定的波束相关信息对应的波束发送PUSCH。
在一个实施例中，预编码可以包括两种方式，一种是基于码本的预编码，另一种是非码本的预编码，本实施例主要应用在基于码本的预编码场景中。
通过为终端配置功能(usage)为“码本”的一个或多个SRS资源集合，并且集合中的SRS资源与波束相关信息相关联，其中，波束相关信息可以是空间关系信息(SpatialRelationInfo)，也可以是其他与波束相关联的信息。
终端接收到SRS资源集合后，可以确定其中每个SRS资源所关联的波束相关信息，进而基于波束相关信息确定SRS资源对应的波束，然后在基于SRS资源发送SRS时，具体在所述SRS资源上，通过所述SRS资源对应的波束发送SRS。
例如在终端中设置有多个天线面板(panel)，不同的天线面板对应不同的波束(不同的波束可以具有不同的波束方向)，那么终端可以确定SRS资源所关联波束对应的天线面板，然后通过所述SRS对应的天线面板，在所述SRS资源上发送SRS。
据此，终端可以在多个SRS资源上，通过多个波束向基站发送SRS。基站在接 收到SRS之后，可以基于所接收到的SRS进行上行信道探测，以确定适合终端中多个天线面板协作传输的多个波束，例如可以检测接收到的SRS的信号强度信息，确定其中信道强度大于预设强度值的SRS所在的SRS资源关联的波束，适用于终端中多个天线面板协作传输。
基站为了向终端指示多个波束，还可以确定每个所述波束对应的指示信息，其中，每个所述波束对应所述基站中不同的传输接收点TRP，进而可以向终端发送所述指示信息，通过所述指示信息指示终端确定用于上行协作传输的波束对应的波束相关信息，并基于所确定的波束相关信息对应的波束发送PUSCH。
终端接收到多个指示信息后，可以确定指示信息所对应的上行协作传输的波束对应的波束相关信息，基于所确定的波束相关信息对应的波束发送PUSCH，具体地，可以根据波束相关信息确定上行协作传输的波束，以及每个波束对应的天线面板，然后通过确定的多个天线面板在对应的波束上向基站发送PUSCH。
据此，基站可以确定用于协作传输的多个波束以及每个波束对应的指示信息，从而通过多个波束对应的多个指示对终端进行指示，使得终端可以根据指示信息确定用于协作传输的多个波束，以及多个波束对应的天线面板，从而能够通过多个天线面板的协作传输，以便满足对PUSCH需要增强传输的业务的需要。所述业务包括但不限于URLLC(Ultra-relaible and Low Latency Communication，超可靠低时延通信)业务。
图2是根据本公开的实施例示出的另一种PUSCH指示方法的示意流程图。如图2所示，所述方法还包括：
在步骤S201中，确定每个所述波束分别适用的预编码信息；
在步骤S202中，将所述预编码信息发送至所述终端。
在一个实施例中，基站通过对接收到的SRS进行上行信道探测，还可以确定每个波束分别适用的预编码信息，所欲预编码信息包括但不限于预编码矩阵指示信息TPMI和秩指示信息RI，其中，确定预编码信息的方式包括但不限于奇异值(SDV)分解算法、基于方程求特征值算法、最大||HW||选择算法等，具体可以根据需要进行选择，本公开不做限制。
然后可以将多个波束对应的多个预编码信息发送至终端，终端可以根据预编码信息对预编码信息对应波束上的PUSCH进行预编码，进而在预编码信息对应波束上 发送预编码后的PUSCH。
可选地，所述指示信息包括以下至少之一：
SRS资源指示标识SRI、上行传输配置指示状态的索引UL TCI state index。
在一个实施例中，基站向终端发送的指示信息，可以是SRI，也可以是UL TCI state index。
在指示信息为SRI的情况下，终端可以确定SRI所指示的SRS资源(例如在所述SRS资源集合中确定SRI所指示的SRS资源)，进而确定SRS资源关联的波束相关信息。
在指示信息为UL TCI state index的情况下，终端可以确定UL TCI state index所指示的UL TCI state，然后确定UL TCI state的参考信号对应的用于上行协作传输的波束对应的波束相关信息。所述参考信号可以是SRS，也可以是状态信息参考信号CSI-RS具体可以根据需要选择。
在相关技术中，可以通过下行TCI state来指示下行传输的波束，本实施例通过UL TCI state index作为指示来指示上行传输的波束，使得上下行的指示方式趋于一致，有利于简化指示逻辑，降低基站指示操作的复杂度。
在一个实施例中，以指示信息为SRI进行示例，基站向终端发送m个SRI，m为终端所支持的上行协作传输的天线面板的数量，基站可以预先构建m个候选集合SRS1至SRSm，那么基站可以通过log 2(N SRSi)个比特指示指候选集合SRSi中SRI，其中，N SRSi是指候选集合SRSi中SRI的数量，1≤i≤m。
另外，针对SRI所指示的每个SRS资源，基站可以分别计算预编码信息，例如针对m个SRI所指示的m个SRS资源，可以计算m个预编码信息，以预编码信息包括TPMI和RI为例，那么可以计算得到m个TPMI和m个RI，其中第i个预编码信息，对应第i个SRI所指示的SRS资源，也就对应该SRS资源对应的天线面板和波束，也即在通过第i个天线面板发送PUSCH时，可以通过第i个预编码信息对PUSCH进行预编码后发送。
可选地，响应于所述终端具备支持上行UL TCI state的能力，所述指示信息包括SRI或UL TCI state index；
响应于所述终端不具备支持上行UL TCI state的能力，所述指示信息包括SRI。
在一个实施例中，有些终端具备支持上UL TCI state的能力，有些终端不具备支持上UL TCI state的能力。对于不具备支持上UL TCI state能力的终端，向终端发送UL TCI state index并不能使得终端按照UL TCI state index确定UL TCI state并上行发送，会造成通信资源的浪费。因此在这种情况下，可以通过SRI作为指示信息，以免浪费通信资源。
而在终端支持上行UL TCI state的能力时，基站既可以将UL TCI state index作为指示信息，也可以将SRI作为指示信息，具体可以根据需要进行选择。
其中，终端可以向基站发送能力信息，以供基站确定终端是否支持上行UL TCI state的能力。
可选地，所述指示信息包括UL TCI state index，所述UL TCI state index所指示的UL TCI state通过以下至少之一作为参考信号：
信道状态信息参考信号CSI-RS、SRS。
在一个实施例中，UL TCI state index可以指示UL TCI state，而UL TCI state可以采用CSI-RS作为参考信号，也可以采用SRS作为参考信号。
可选地，所述UL TCI state还用于指示所述UL TCI state index所对应的波束的路损参考信号pathloss RS资源。
在一个实施例中，UL TCI state index指示UL TCI state，UL TCI state指示UL TCI state index所对应的波束的pathloss RS资源，从而终端可以基于该pathloss RS资源在该波束上发送pathloss RS，以供基站确定需要补偿的路径损耗。
根据本公开的实施例，UL TCI state可以以CSI-RS作为参考信号，或者以SRS作为参考信号，还可以在以CSI-RS作为参考信号的基础上包含pathloss RS资源，或者在以SRS作为参考信号的基础上包含pathloss RS资源。
可选地，响应于所述终端上行传输支持波束一致性，所述UL TCI state index所指示的UL TCI state通过CSI-RS作为参考信号，或通过SRS作为参考信号。
在一个实施例中，由于终端向基站发送信息的动作属于上行，而CSI-RS属于下行信号，终端可以将SRS作为UL TCI state的参考信号，在终端上行传输支持波束一致性的情况下，那么对于下行的CSI-RS，也可以作为UL TCI state的参考信号。
可选地，响应于所述终端上行传输不支持波束一致性，所述UL TCI state index 所指示的UL TCI state通过SRS作为参考信号。
在一个实施例中，在终端上行传输不支持波束一致性的情况下，属于下行信号的CSI-RS就不能作为UL TCI state的参考信号，只能采用SRS作为UL TCI state的参考信号。
图3是根据本公开的实施例示出的又一种PUSCH指示方法的示意流程图。如图3所示，响应于所述UL TCI state不用于指示所述UL TCI state index所对应的波束的pathloss RS资源，所述方法还包括：
在步骤S301中，向所述终端发送资源配置信息以配置每个所述波束相关联的pathloss RS资源。
在一个实施例中，在UL TCI state不用于指示所述UL TCI state index所对应的波束的pathloss RS资源的情况下，基站还可以向终端发送资源配置信息以配置每个波束相关联的pathloss RS资源，使得终端可以基于该pathloss RS资源在该波束上发送pathloss RS，以供基站确定需要补偿的路径损耗。
在一个实施例中，所述资源配置信息可以通过MAC CE(介质访问控制层控制元素)指示。
图4是根据本公开的实施例示出的又一种PUSCH指示方法的示意流程图。如图4所示，所述指示信息包括UL TCI state index，所述方法还包括：
在步骤S401中，向所述终端发送波束配置信息(例如携带在无线资源控制RRC信息中)，以为所述终端配置多个备选波束相关信息；
在步骤S402中，向所述终端发送波束激活信息(例如携带在MAC CE中)，以指示所述终端在所述多个备选波束相关信息中激活多个可用波束相关信息；
其中，所述UL TCI state index用于指示所述终端在所述可用波束相关信息中确定用于上行协作传输的波束对应的波束相关信息。
在一个实施例中，由于备选波束相关信息的数量可以较多，例如可以为64个，若直接通过指示信息进行指示，需要占用过多的比特数，因此本实施例可以先通过波束配置信息，配置多个备选波束相关信息，然后进一步向终端发送波束激活信息，在多个备选波束相关信息中激活多个可用波束相关信息，例如在64个备选波束相关信息中激活8个作为可用波束相关信息，那么针对每个用于上行协作传输的波束对应的波 束相关信息，只需能够指示8种情况的指示信息即可进行指示，而8种情况只需要占用3比特，有利于减少指示信息所需占用比特数，节约通信资源。
可选地，所述UL TCI state index与波束相关信息一一对应。
在一个实施例中，UL TCI state index与波束相关信息可以是一一对应的，也即每个UL TCI state index可以独立指示一个波束相关信息，具体可以通过UL TCI state index指示UL TCI state，UL TCI state的参考信号为SRS，那么UL TCI state的参考信号SRS对应的SRS资源进一步对应的波束相关信息，就是UL TCI state index所指示的波束相关信息。
如以下表1所示，激活8个可用波束相关信息，其中的UL TCI state从A0到A7的含义可以根据需要设置。
基站可以向终端发送一个或多个指示信息，也即可以向终端发送一个或多个UL TCI state index，例如向终端发送两个UL TCI state index，分别为0和1，那么根据这两个UL TCI state index，可以确定指示的两个UL TCI state对应的SRS资源分别为SRS0和SRS3，那么SRS0和SRS3这两个SRS资源对应的波束相关信息，就是基站通过指示信息所指示的2个波束相关信息。
UL TCI state index UL TCI state SRS资源
0 A0 SRS0
1 A1 SRS3
2 A2 SRS5
3 A3 SRS6
4 A4 SRS9
5 A5 SRS11
6 A6 SRS14
7 A7 SRS15
表1
可选地，所述UL TCI state index对应单个和/或多个波束相关信息。
在一个实施例中，UL TCI state index可以对应单个和/或多个波束相关信息， 也即UL TCI state index可以独立指示一个波束相关信息，UL TCI state index还可以指示多个波束相关信息。
具体可以通过UL TCI state index指示UL TCI state，UL TCI state的参考信号为SRS，那么UL TCI state的参考信号SRS对应的SRS资源进一步对应的波束相关信息，就是UL TCI state index所指示的波束相关信息。
如以下表2所示，激活8个可用波束相关信息，其中的UL TCI state从A0到A7的含义可以根据需要设置。
基站可以向终端发送一个或多个指示信息，也即可以向终端发送一个或多个UL TCI state index，例如向终端发送两个UL TCI state index，分别为0和1，那么根据这两个UL TCI state index，可以确定指示的两个UL TCI state对应的SRS资源分别为SRS0和SRS1，那么SRS0和SRS1这两个SRS资源对应的波束相关信息，就是基站通过指示信息所指示的2个波束相关信息。
例如向终端发送2个UL TCI state index，为3，那么根据这两个UL TCI state index，可以确定指示的UL TCI state对应的SRS资源为SRS1和SRS2，那么SRS1和SRS2这两个SRS资源对应的波束相关信息，就是基站通过指示信息所指示的2个波束相关信息。
UL TCI state index UL TCI state SRS资源
0 A0 SRS0
1 A1 SRS1
2 A2 SRS2
3 A3 SRS1、SRS2
4 A4 SRS2、SRS5
5 A5 SRS3、SRS6
6 A6 SRS1、SRS8
7 A7 SRS4、SRS9
表2
在本实施例中，UL TCI state index不仅对应单个波束相关信息，还对应多个波 束相关信息，并且UL TCI state index对应的单个波束相关信息，可以包含在对应的多个波束相关信息中，据此，允许基站可以进行回退指示，例如需要通过UL TCI state index为4来指示SRS2和SRS5这两个SRS资源分别对应的波束相关信息，但是确定通过SRS5的SRS资源发送的SRS不满足信号强度等要求，也即终端通过基于SRS5的SRS资源对应的波束相关信息确定的天线面板发送信号不满足要求，那么可以回退指示为UL TCI state index为2，也即仅指示SRS2这个SRS资源对应的波束相关信息。
图5是根据本公开的实施例示出的一种PUSCH发送方法的示意流程图。本实施例所示的PUSCH发送方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。所述终端可以作为用户设备与基站通信，所述基站包括但不限于4G基站、5G基站、6G基站。在一个实施例中，所述基站可以是上述任一实施例所述的指示方法所适用的基站。
如图5所示，所述PUSCH发送方法可以包括以下步骤：
在步骤S501中，接收基站为上行数据传输调度的功能为“码本”的一个或多个信道探测参考信号SRS资源集合配置，所述SRS资源集合中的SRS资源与波束相关信息相关联；
在步骤S502中，基于所述SRS资源向所述基站发送SRS；
在步骤S503中，接收所述基站根据接收到的SRS确定的用于上行协作传输的多个波束中每个所述波束对应的指示信息，其中，每个所述波束对应所述基站中不同的传输接收点TRP；
在步骤S504中，根据所述指示信息确定用于上行协作传输的波束对应的波束相关信息，并基于所确定的波束相关信息对应的波束向所述基站发送PUSCH。
在一个实施例中，预编码可以包括两种方式，一种是基于码本的预编码，另一种是非码本的预编码，本实施例主要应用在基于码本的预编码场景中。

据此，终端可以在多个SRS资源上，通过多个波束向基站发送SRS。基站在接收到SRS之后，可以基于所接收到的SRS进行上行信道探测，以确定适合终端中多个天线面板协作传输的多个波束，例如可以检测接收到的SRS的信号强度信息，确定其中信道强度大于预设强度值的SRS所在的SRS资源关联的波束，适用于终端中多个天线面板协作传输。
基站为了向终端指示多个波束，还可以确定每个所述波束对应的指示信息，其中，每个所述波束对应所述基站中不同的传输接收点TRP，进而可以向终端发送所述指示信息，通过所述指示信息指示终端确定用于上行协作传输的波束对应的波束相关信息，并基于所确定的波束相关信息对应的波束发送PUSCH。
终端接收到多个指示信息后，可以确定指示信息所对应的上行协作传输的波束对应的波束相关信息，基于所确定的波束相关信息对应的波束发送PUSCH，具体地，可以根据波束相关信息确定上行协作传输的波束，以及每个波束对应的天线面板，然后通过确定的多个天线面板在对应的波束上向基站发送PUSCH。
据此，基站可以确定用于协作传输的多个波束以及每个波束对应的指示信息，从而通过多个波束对应的多个指示对终端进行指示，使得终端可以根据指示信息确定用于协作传输的多个波束，以及多个波束对应的天线面板，从而能够通过多个天线面板的协作传输，以便满足对PUSCH需要增强传输的业务的需要。所述业务包括但不限于URLLC业务。
图6是根据本公开的实施例示出的另一种PUSCH发送方法的示意流程图。如图6所示，所述方法还包括：
在步骤S601中，接收所述基站发送的每个所述波束分别适用的预编码信息；
其中，所述基于所确定的波束相关信息对应的波束向所述基站发送PUSCH包括：

然后可以将多个波束对应的多个预编码信息发送至终端，终端可以根据预编码信息对预编码信息对应波束上的PUSCH进行预编码，进而在预编码信息对应波束上发送预编码后的PUSCH。
可选地，所述指示信息包括以下至少之一：
SRS资源指示标识SRI、上行传输配置指示状态的索引UL TCI state index。
在一个实施例中，基站向终端发送的指示信息，可以是SRI，也可以是UL TCI state index。
在指示信息为SRI的情况下，终端可以确定SRI所指示的SRS资源(例如在所述SRS资源集合中确定SRI所指示的SRS资源)，进而确定SRS资源关联的波束相关信息。
在指示信息为UL TCI state index的情况下，终端可以确定UL TCI state index所指示的UL TCI state，然后确定UL TCI state的参考信号对应的用于上行协作传输的波束对应的波束相关信息。所述参考信号可以是SRS，也可以是状态信息参考信号CSI-RS具体可以根据需要选择。
在相关技术中，可以通过下行TCI state来指示下行传输的波束，本实施例通过UL TCI state index作为指示来指示上行传输的波束，使得上下行的指示方式趋于一致，有利于简化指示逻辑，降低基站指示操作的复杂度。
在一个实施例中，以指示信息为SRI进行示例，基站向终端发送m个SRI，m为终端所支持的上行协作传输的天线面板的数量，基站可以预先构建m个候选集合SRS1至SRSm，那么基站可以通过log 2(N SRSi)个比特指示指候选集合SRSi中SRI，其中，N SRSi是指候选集合SRSi中SRI的数量，1≤i≤m。
另外，针对SRI所指示的每个SRS资源，基站可以分别计算预编码信息，例如针对m个SRI所指示的m个SRS资源，可以计算m个预编码信息，以预编码信息包括TPMI和RI为例，那么可以计算得到m个TPMI和m个RI，其中第i个预编码信息，对应第i个SRI所指示的SRS资源，也就对应该SRS资源对应的天线面板和波 束，也即在通过第i个天线面板发送PUSCH时，可以通过第i个预编码信息对PUSCH进行预编码后发送。
可选地，响应于所述终端具备支持上行UL TCI state的能力，所述指示信息包括SRI或UL TCI state index；
响应于所述终端不具备支持上行UL TCI state的能力，所述指示信息包括SRI。
在一个实施例中，有些终端具备支持上UL TCI state的能力，有些终端不具备支持上UL TCI state的能力。对于不具备支持上UL TCI state能力的终端，向终端发送UL TCI state index并不能使得终端按照UL TCI state index确定UL TCI state并上行发送，会造成通信资源的浪费。因此在这种情况下，可以通过SRI作为指示信息，以免浪费通信资源。
而在终端支持上行UL TCI state的能力时，基站既可以将UL TCI state index作为指示信息，也可以将SRI作为指示信息，具体可以根据需要进行选择。
其中，终端可以向基站发送能力信息，以供基站确定终端是否支持上行UL TCI state的能力。
图7是根据本公开的实施例示出的又一种PUSCH发送方法的示意流程图。如图7所示，所述指示信息包括UL TCI state index，所述根据所述指示信息确定用于上行协作传输的波束对应的波束相关信息包括：
在步骤S701中，确定所述UL TCI state index所指示的UL TCI state，以及确定所述UL TCI state的参考信号对应的用于上行协作传输的波束对应的波束相关信息。
在一个实施例中，基站可以通过UL TCI state index指示UL TCI state，UL TCI state的参考信号为SRS，那么UL TCI state的参考信号SRS对应的SRS资源进一步对应的波束相关信息，就是UL TCI state index所指示的波束相关信息。那么终端可以确定所述UL TCI state index所指示的UL TCI state，进而确定UL TCI state的参考信号对应的用于上行协作传输的波束对应的波束相关信息。
图8是根据本公开的实施例示出的又一种PUSCH发送方法的示意流程图。如图8所示，所述方法还包括：
在步骤S801中，根据所述UL TCI state确定所述UL TCI state index所对应的波束的路损参考信号pathloss RS资源。
在一个实施例中，UL TCI state index指示UL TCI state，UL TCI state指示UL TCI state index所对应的波束的pathloss RS资源，从而终端可以基于该pathloss RS资源在该波束上发送pathloss RS，以供基站确定需要补偿的路径损耗。
根据本公开的实施例，UL TCI state可以以CSI-RS作为参考信号，或者以SRS作为参考信号，还可以在以CSI-RS作为参考信号的基础上包含pathloss RS资源，或者在以SRS作为参考信号的基础上包含pathloss RS资源。
可选地，所述UL TCI state的参考信号包括以下至少之一：
信道状态信息参考信号CSI-RS、SRS。
在一个实施例中，UL TCI state index可以指示UL TCI state，而UL TCI state可以采用CSI-RS作为参考信号，也可以采用SRS作为参考信号。
可选地，响应于所述终端上行传输支持波束一致性，所述UL TCI state的参考信号包括CSI-RS或SRS。
在一个实施例中，由于终端向基站发送信息的动作属于上行，而CSI-RS属于下行信号，终端可以将SRS作为UL TCI state的参考信号，在终端上行传输支持波束一致性的情况下，那么对于下行的CSI-RS，也可以作为UL TCI state的参考信号。
可选地，响应于所述终端上行传输不支持波束一致性，所述UL TCI state的参考信号包括SRS。
在一个实施例中，在终端上行传输不支持波束一致性的情况下，属于下行信号的CSI-RS就不能作为UL TCI state的参考信号，只能采用SRS作为UL TCI state的参考信号。
图9是根据本公开的实施例示出的又一种PUSCH发送方法的示意流程图。如图9所示，所述方法还包括：
在步骤S901中，接收所述基站发送的资源配置信息以确定每个所述波束的pathloss RS资源。
在一个实施例中，在UL TCI state不用于指示所述UL TCI state index所对应的波束的pathloss RS资源的情况下，基站还可以向终端发送资源配置信息以配置每个波束相关联的pathloss RS资源，使得终端可以基于该pathloss RS资源在该波束上发送pathloss RS，以供基站确定需要补偿的路径损耗。
在一个实施例中，所述资源配置信息可以通过MAC CE指示。
图10是根据本公开的实施例示出的又一种PUSCH发送方法的示意流程图。如图10所示，所述指示信息包括UL TCI state index，所述根据所述指示信息确定用于上行协作传输的波束对应的波束相关信息包括：
在步骤S1001中，接收所述基站发送的波束配置信息，根据所述波束配置信息确定多个备选波束相关信息；
在步骤S1002中，接收所述基站发送的波束激活信息，根据所述波束激活信息在所述多个备选波束相关信息中激活多个可用波束相关信息；
在步骤S1003中，根据所述UL TCI state index在所述可用波束相关信息中确定用于上行协作传输的波束对应的波束相关信息。
在一个实施例中，由于备选波束相关信息的数量可以较多，例如可以为64个，若直接通过指示信息进行指示，需要占用过多的比特数，因此本实施例可以先通过波束配置信息，配置多个备选波束相关信息，然后进一步向终端发送波束激活信息，在多个备选波束相关信息中激活多个可用波束相关信息，例如在64个备选波束相关信息中激活8个作为可用波束相关信息，那么针对每个用于上行协作传输的波束对应的波束相关信息，只需能够指示8种情况的指示信息即可进行指示，而8种情况只需要占用3比特，有利于减少指示信息所需占用比特数，节约通信资源。
可选地，所述UL TCI state index与波束相关信息一一对应。
在一个实施例中，UL TCI state index与波束相关信息可以是一一对应的，也即每个UL TCI state index可以独立指示一个波束相关信息，具体可以通过UL TCI state index指示UL TCI state，UL TCI state的参考信号为SRS，那么UL TCI state的参考信号SRS对应的SRS资源进一步对应的波束相关信息，就是UL TCI state index所指示的波束相关信息。
如表1所示，激活8个可用波束相关信息，其中的UL TCI state从A0到A7的含义可以根据需要设置。
基站可以向终端发送一个或多个指示信息，也即可以向终端发送一个或多个UL TCI state index，例如向终端发送两个UL TCI state index，分别为0和1，那么根据这两个UL TCI state index，可以确定指示的两个UL TCI state对应的SRS资源分别为SRS0和SRS3，那么SRS0和SRS3这两个SRS资源对应的波束相关信息，就是基站 通过指示信息所指示的2个波束相关信息。
可选地，所述UL TCI state index对应单个和/或多个波束相关信息。
在一个实施例中，UL TCI state index可以对应单个和/或多个波束相关信息，也即UL TCI state index可以独立指示一个波束相关信息，UL TCI state index还可以指示多个波束相关信息。
具体可以通过UL TCI state index指示UL TCI state，UL TCI state的参考信号为SRS，那么UL TCI state的参考信号SRS对应的SRS资源进一步对应的波束相关信息，就是UL TCI state index所指示的波束相关信息。
如表2所示，激活8个可用波束相关信息，其中的UL TCI state从A0到A7的含义可以根据需要设置。
基站可以向终端发送一个或多个指示信息，也即可以向终端发送一个或多个UL TCI state index，例如向终端发送两个UL TCI state index，分别为0和1，那么根据这两个UL TCI state index，可以确定指示的两个UL TCI state对应的SRS资源分别为SRS0和SRS1，那么SRS0和SRS1这两个SRS资源对应的波束相关信息，就是基站通过指示信息所指示的2个波束相关信息。
例如向终端发送2个UL TCI state index，为3，那么根据这两个UL TCI state index，可以确定指示的UL TCI state对应的SRS资源为SRS1和SRS2，那么SRS1和SRS2这两个SRS资源对应的波束相关信息，就是基站通过指示信息所指示的2个波束相关信息。
在本实施例中，UL TCI state index不仅对应单个波束相关信息，还对应多个波束相关信息，并且UL TCI state index对应的单个波束相关信息，可以包含在对应的多个波束相关信息中，据此，允许基站可以进行回退指示，例如需要通过UL TCI state index为4来指示SRS2和SRS5这两个SRS资源分别对应的波束相关信息，但是确定通过SRS5的SRS资源发送的SRS不满足信号强度等要求，也即终端通过基于SRS5的SRS资源对应的波束相关信息确定的天线面板发送信号不满足要求，那么可以回退指示为UL TCI state index为2，也即仅指示SRS2这个SRS资源对应的波束相关信息。
