下面结合附图对本公开所提供的CSI报告的获取方法、装置及存储介质进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种CSI报告的获取方法的流程图。
如图2所示，本公开实施例提供的一种CSI报告的获取方法，该方法由第一终端执行，该方法可以包括但不限于如下步骤：
S21：接收基于单播连接的第二终端发送的CSI报告请求；接收第二终端发送的配置信息。
需要说明的是，本公开实施例中，第一终端与第二终端建立单播连接，第二终端在PSCCH(Physical Sidelink Control Channel，侧链路控制信道)上发送Sidelink控制信息(Sidelink Control Information，SCI)，其中携带传输数据的资源位置以及源终端标识和目标终端标识等，其中，第一终端与第二终端建立单播连接，源终端标识和目标终端标识分别对应第一终端和第二终端，从而第一终端在收到SCI后，根据其中的源终端标识和目的终端标识确定接收对应的数据以及对应哪个进程。其中，单播连接，每个终端都对应一个目的标识。
当然，上述第一终端与第二终端的单播连接的方式仅作为示意，第一终端与第二终端的单播连接的方式还可以为相关技术中的其他方式，本公开实施例对此不作具体限制。
本公开实施例中，第一终端接收第二终端发送的SCI，其中SCI携带CSI报告请求。第一终端接收到CSI报告请求后，测量与第二终端的Sidelink通信的无线信道质量。其中，在第一终端与第二终端之间仅通过一个频带进行Sidelink通信的情况下，第一终端接收到第二终端发送的CSI报告请求后，会对该频带的信号进行测量。
S22：确定多个频带中的目标频带。
可以理解的是，对于第一终端与第二终端之间可以通过多个频带进行Sidelink通信的情况下，第一终端接收到第二终端发送的CSI报告请求，无法确定测量哪个频带的信道质量。
基于此，本公开实施例中，第二终端发送的CSI报告请求指示多个频带中的目标频带的信息，从而，第一终端接收到第二终端发送的CSI报告请求，可以根据CSI报告请求指示多个频带中的目标频带的信息，确定目标频带。
或者，本公开实施例中，第二终端向第一终端发送配置信息，其中，配置信息指示多个频带中的目标频带的信息，第一终端接收第二终端发送的配置信息，可以根据配置信息指示多个频带中的目标频带的信息，确定目标频带。

其中，本公开实施例中，目标频带可以为一个或多个特定的频点(载波)或者特定的频率带宽部分。
S23：向第二终端发送目标频带的CSI报告。
本公开实施例中，第一终端在确定目标频带之后，测量目标频带的无线信道质量，生成目标频带的CSI报告，之后，可以向第二终端发送目标频带的CSI报告。
在一些实施例中，CSI报告指示目标频带的信道质量指示CQI(Channel Quality Indicator，信道质量指示)，以及频带标识；其中，频带标识用于确定CSI报告对应的目标频带。
本公开实施例中，第一终端发送至第二终端的目标频带的CSI报告指示目标频带的CQI，以及频带标识，其中，频带标识用于确定CSI报告对应的目标频带，以使第二终端接收到CSI报告后，可以确定目标频带的CSI报告，以及目标频带的CQI。
在一些实施例中，在配置信息包括频带列表，频带列表包括至少一个频带的情况下，频带标识为第二索引标识，第二索引标识指示频带列表中的第二位置，其中，第二索引标识指示的频带列表中的第二位置的第五频带为CSI报告对应的目标频带。
本公开实施例中，第二终端发送的配置信息包括频带列表，包括至少一个频带，CSI报告指示的频带标识可以为第二索引标识，第二索引标识指示频带列表中的第二位置，则第一终端可以根据第二索引标识指示频带列表中的第二位置以及频带列表确定目标频带，在第二索引标识指示频带列表中的第二位置的频带为第五频带的情况下，则可以确定接收到的是第五频带的CSI报告。
为了方便理解，本公开实施例提供一示例性实施例。

需要说明的是，上述示例仅作为示意，频带列表的格式以及第二索引标识的格式还可以为其他方式，例如频带列表中还可以包括其他部分，或者频带列表中不包括序号列等，第二索引标识还可以为列表的形式，本公开实施例对此不作具体限制。
