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SRS资源配置方法的示意流程图。本实施例所示的SRS资源配置方法可以适用于网络设备，所述网络设备可以是5G基站、4G基站，车联网通信中的路侧单元、车载设备终端等。所述网络设备可以基于波束(beam)扫描的方式与终端通信，也可以基于其他方式与终端通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、物联网设备终端、工业物联网设备终端、车联网通信中的车载设备终端等电子设备。在所述终端中可以设置有至少一个天线面板(panel)，在天线面板上可以设置有至少一个天线端口，所述天线端口可以是指逻辑概念中天线的端口，也可以是实际概念中的物理天线。
如图1所示，所述SRS资源配置方法可以包括以下步骤：
在步骤S101中，向终端发送配置信息，其中，所述配置信息用于指示至少一个探测参考信号SRS(sounding reference signal)资源集，每个所述SRS资源集包含至少一个SRS资源(同一SRS资源集中不同的SRS资源，对应不同的正交频分复用OFDM符号)；
所述配置信息还用于指示发送每个所述SRS资源的至少一个天线端口的天线端口标识，以及所述至少一个天线端口标识中每个天线端口标识对应的发送波束方向，不同的所述天线端口标识对应不同的发送波束方向。例如在配置信息中可以包含spatialrelationinfo信息，那么可以通过该信息指示每个所述SRS资源的至少一个天线 端口标识的发送波束方向。除了spatialrelationinfo信息，也可以在配置信息中设置传输配置指示TCI状态信息，具体可以是上行UL TCI来指示每个所述SRS资源的至少一个天线端口标识的发送波束信息。
在一个实施例中，网络设备可以通过向终端发送配置信息，向终端指示至少一个SRS资源集，每个所述SRS资源集包含至少一个SRS资源，从而使得终端可以通过至少一个天线端口发送SRS资源。需要说明的是，本实施例以及后续实施例中的发送SRS资源，具体是指在SRS时频域资源上发送SRS序列。
在5G NR系统中，基于信道的互易性，基站可以测量终端发送的SRS来确定下行信道状态信息。其中，终端发送SRS所用的SRS资源，可以由基站配置。
具体地，基站可以向终端发送配置信息，以通过配置信息向终端指示SRS资源集，每个SRS资源集中包括至少一个SRS资源，从而使得终端可以通过终端中的天线端口在SRS时频域资源上发送SRS序列。
在相关技术中，基站默认终端只有一个天线面板，会为所有天线端口指示相同的发送波束方向，作为每个天线端口发送SRS资源的发送波束方向。由于终端可以包括多个天线端口，可以通过不同的天线端口发送SRS序列，因此向终端指示的发送SRS序列的发送波束方向，具体是指示终端的天线端口发送SRS序列的发送波束方向。
但是在实际情况下，不同天线端口所处的环境不同，例如在终端包括多个天线面板的情况，不同天线端口可以处于不同的天线面板，而对于不同天线面板而言，最适于与基站通信的发送波束方向可以有所不同。
例如对于天线端口A而言，最适于与基站通信的发送波束方向为a，但是基站为所有天线端口指示的发送SRS资源的发送波束方向为b，那么天线端口A会按照发送波束方向b向基站发送SRS资源，那么基站接收到SRS之后，所确定的下行信道状态信息，就是发送波束方向b对应的下行信道状态信息。
但是基站所需确定的下行信道状态信息，一般是天线端口A最适于(例如信号质量最好)与基站通信的发送波束方向对应信道的下行信道状态信息，也即发送波束方向a对应信道的下行信道状态信息，因此为所有天线端口配置相同发送波束方向发送SRS资源，导致基站基于接收到的SRS难以准确地确定各个波束方向的下行信道状态信息。
根据本公开的实施例，网络设备向终端发送的配置信息，不仅可以向终端指示 SRS资源集，还可以指示SRS资源集中每个SRS资源的至少一个天线端口的天线端口标识，以及每个天线端口标识对应的发送波束方向，并且不同的天线端口标识对应不同的发送波束方向。
需要说明的是，对于某个SRS资源而言，可以对应一个天线端口(也即可以通过一个天线端口发送)，也可以对应多个天线端口(也可以通过多个天线端口发送)，这可以根据终端的天线收发能力来确定。
例如天线收发能力为N发N收，也即接收天线的数目和发送天线的数目相同，那么一个SRS资源可以对应N个天线端口，N为1、2、或者4等；例如天线接收能力为一发两收，也即终端中设置有2个接收天线和1个发送天线，那么一个SRS资源可以对应1个天线端口；例如天线接收能力为两发四收，也即终端中设置有4个接收天线和2个发送天线，那么一个SRS资源可以对应2个天线端口。
由于本实施例通过配置信息指示发送每个SRS资源的至少一个天线端口的天线端口标识，以及至少一个天线端口标识中每个天线端口标识对应的发送波束方向，并且不同的天线端口标识对应不同的发送波束方向。
对于某个SRS资源而言，即使需要通过多个天线端口来发送这个SRS资源，那么不同天线端口发送SRS资源的发送波束方向可以不同。据此，有利于灵活配置不同天线端口发送SRS资源的发送波束方向，进而有利于确保网络设备基于接收到的SRS准确地确定下行信道状态信息。
图2是根据本公开的实施例示出的另一种SRS配置方法的示意流程图。如图2所示，在向终端发送配置信息之前，所述方法还包括：
在步骤S102中，设置每个所述SRS资源集中SRS资源的数目，其中，所述SRS资源的数目与所述终端中接收天线的数目成正比，与所述终端中发送天线的数目成反比。
在一个实施例中，网络设备还可以设置每个SRS资源集中SRS资源的数目，其中，可以根据终端中接收天线的数目和发送天线的数目进行设置，具体地，可以设置SRS资源的数目与终端中接收天线的数目成正比，与终端中发送天线的数目成反比。
例如终端中接收天线的数目为Rx，发送天线的数目为Tx，那么可以设置SRS资源集中SRS资源的数目为k*Rx/Tx，其中k为比例系数，可以根据需要进行设置。
例如终端包括n(n≥1)个天线面板，以n＝2为例，每个天线面板上接收天线 和发送天线的关系(例如比值)是相同的，具体终端的天线能力为二发四收，那么每个天线面板上设置有1个发送天线和2个接收天线，由于存在4个接收天线，那么网络设备需要接收4个SRS资源才能确定这4个接收天线分别对应的下行信道状态信息，例如信道状态信息CSI(channel state information)。
若在这种情况下，不同天线面板能用于同时发送(具体是上行发送)，也就是说，两个天线面板各自具有一个发送天线端口，针对同一个SRS资源而言，可以使用这两个发送天线端口在该SRS时频域资源发送SRS序列，那么可以设置k＝1，也即每个SRS资源集中包含2/1，也即2个SRS资源。
例如两个发射天线端口分别为X和Y，2个SRS资源分别为SRS1和SRS2，可以通过X和Y在第一时间发送SRS1，以及通过X和Y在第二时间发送SRS2，从而共计发送2×2＝4次SRS资源，进而确保网络设备能够接收4个SRS资源，以便准确确定4个接收天线分别对应的下行信道状态信息。
可选地，所述SRS资源的数目与所述终端中天线面板的数目成正比，其中，所述终端包括多个天线面板，且所述多个天线面板不能用于同时发送。
在一个实施例中，在SRS资源集中SRS资源的数目与终端中接收天线的数目成正比，与终端中发送天线的数目成反比的基础上，若终端中多个天线慢板不能用于同时发送，那么可以进一步设置SRS资源的数目与终端中天线面板的数目成正比。
仍以n＝2为例，每个天线面板上接收天线和发送天线的关系是相同的，具体终端具体的天线能力为二发四收，那么每个天线面板上设置有1个发送天线和2个接收天线，由于存在4个接收天线，那么网络设备需要接收4个SRS资源才能确定这4个接收天线分别对应的下行信道状态信息。
由于不同天线面板不能用于同时发送(具体是上行发送)，也就是说，两个天线面板各自具有一个发送天线，针对同一个SRS资源而言，只能分别使用这两个发送天线之一在该SRS时频域资源发送SRS序列，那么可以设置k等于天线面板的数目n，n＝2，则k*Rx/Tx＝2×4/2＝4，也即每个SRS资源集中包含4个SRS资源，从而通过2个发送天线，可以依次发送这4个SRS资源。
例如两个发射天线端口分别为X和Y，4个SRS资源分别为SRS1、SRS2、SRS3和SRS4，可以通过X在第一时间发送SRS1和在第二时间发送SRS2，通过Y在第三时间发送SRS3和在第四时间发送SRS4，从而共计发送1×4＝4个SRS资源，进而确 保网络设备能够接收4个SRS资源，以便准确确定4个接收天线分别对应的下行信道状态信息。
可选地，所述配置信息包括波束方向指示信息，所述波束方向指示信息用于指示所述发送波束方向，其中，所述波束方向指示信息包括参考信号标识。

在一个实施例中，网络设备可以在配置信息中携带参考信号标识，而终端中可以预先存储有参考信号标识与发送波束方向的关联关系，从而可以通过参考信号标识作为波束方向指示信息向终端指示发送波束方向，终端接收到配置信息后，可以根据所述关联关系查询配置信息中参考信号标识对应的发送波束方向。
可选地，所述波束方向指示信息还用于指示以下至少之一：

所述参考信号标识对应的参考信号所属的传输接收点Transmission Reception Point(简称TRP，例如可以是小区的传输接收点)的标识；
所述参考信号标识对应的参考信号所属的天线面板的索引(panel index)；
所述参考信号标识对应的参考信号所属的天线面板或传输接收点的控制资源集池索引(CORESETpool index，其中CORESET的全称为Control Resource Set)。
在一个实施例中，网络设备可以为终端配置多个参考信号集合，在参考信号集合中可以包含多个参考信号，同一个参考信号集合中不同的参考信号对应的参考信号标识是不同的，但是在不同的参考信号集合中，可以存在相同的参考信号标识。那么为了准确地区分参考信号标识对应的参考信号，网络设备还可以通过波束方向指示信息指示该参考信号标识对应的参考信号所述的参考信号集合标识，以对终端进行进一步具体地指示。
其中，参考信号可以与小区是相关的，那么网络设备可以通过波束方向指示信息进一步指示小区的标识，例如所指示的小区的标识为Cell1，所指示的参考信号标识为SSB2，那么终端可以确定发送波束方向为Cell1对应的参考信号标识为SSB2的SSB 对应的波束方向。
参考信号还可以与传输接收点是相关的，那么网络设备可以通过波束方向指示信息进一步指示该参考信号标识对应的参考信号所属的传输接收点的标识；参考信号还可以与天线面板是相关的，那么网络设备可以通过波束方向指示信息进一步指示该参考信号标识对应的参考信号所属的天线面板的索引；传输接收点索引或天线面板索引还可以通过与之关联的控制资源集池索引来指示，那么网络设备可以通过波束方向指示信息进一步指示天线面板或传输接收点的控制资源集池的索引。

所述终端中天线面板的数目、每个所述天线面板中发送天线的数目和接收天线的数目、所述终端中的多个天线面板是否能够用于同时发送。
在一个实施例中，终端可以先向网络设备发送天线信息，以便网络设备可以根据天线信息生成配置信息，例如可以使得天线基于天线信息确定配置的SRS资源集中SRS资源的数目，进而基于此生成配置信息来向终端指示SRS资源集中SRS资源的数目。
具体地，天线信息包括以下至少之一：
所述终端中天线面板的数目、每个所述天线面板中发送天线的数目和接收天线的数目、所述终端中的多个天线面板是否能够用于同时发送。
例如根据天线面板中发送天线的数目和接收天线的数目，网络设备设置每个所述SRS资源集中SRS资源的数目，使得SRS资源的数目与所述终端中接收天线的数目成正比，与终端中发送天线的数目成反比，然后基于所确定的SRS资源集中SRS资源的数目生成配置信息。
例如根据终端中的多个天线面板是否能够用于同时发送，网络设备可以设置每个所述SRS资源集中SRS资源的数目，使得SRS资源的数目与所述终端中天线面板的数目成正比，然后基于所确定的SRS资源集中SRS资源的数目生成配置信息。
另外，在终端中只有一个天线面板的情况下，那么终端中的所有天线端口都属 于同一个天线面板，在这种情况下，可以选择性地配置所有天线端口发送SRS资源的发送波束方向相同。
并且网络设备所配置的不同SRS资源之间的时间间隔，可以大于预设时间间隔，预设时间间隔可以等于终端切换天线端口所需时长，以确保终端具有足够的时间切换天线端口，从而顺利地发送SRS资源。

由于本实施例通过配置信息指示发送每个SRS资源的至少一个天线端口的天 线端口标识，以及至少一个天线端口标识中每个天线端口标识对应的发送波束方向，并且不同的天线端口标识对应不同的发送波束方向。
对于某个SRS资源而言，即使需要通过多个天线端口来发送这个SRS资源，那么不同天线端口发送SRS资源的发送波束方向可以不同。
据此，有利于灵活配置不同天线端口发送SRS资源的发送波束方向，进而有利于确保网络设备基于接收到的SRS准确地确定下行信道状态信息。
可选地，所述SRS资源的数目与所述终端中接收天线的数目成正比，与所述终端中发送天线的数目成反比。
可选地，所述终端包括多个天线面板，且所述多个天线面板不能用于同时发送，所述SRS资源的数目与所述天线面板的数目成正比。
