步骤101、向基站发送RIS阵列的波束信息。
需要说明的是，在本公开的一个实施例之中，波束信息可以包括RIS阵列支持的反射波束集合和/或RIS阵列支持的透射波束集合。其中，在本公开的一个实施例之中，反射波束集合可以包括RIS阵列支持的至少一个反射波束对应的角度范围和波束索引。以及，在本公开的一个实施例之中，透射波束集合可以包括RIS阵列支持的至少一个透射波束对应的角度范围和波束索引。
在本公开的另一个实施例之中，波束信息可以包括以下至少一种：

RIS阵列能够同时支持的反射波束的数量；
RIS阵列能够同时支持的透射波束的数量。
以及，在本公开的一个实施例之中，上述角度范围可以包括第一维角度范围和第二维角度范围。具体的，在本公开的一个实施例之中，第一维角度范围可以是水平方位角范围。在本公开的一个实施例之中，第二维角度范围可以是垂直方位角范围。
进一步地，在本公开的一个实施例之中，上述波束索引可以是二维索引。在本公开的另一个实施例之中，上述波束索引可以是一维索引。其中，关于上述角度范围和波束索引会在后续的实施例中详细介绍。
步骤102、获取基站发送的至少一个目标波束索引，并确定至少一个时隙位置信息。
其中，在本公开的一个实施例之中，上述的至少一个目标波束索引可以是基站通过信令发送至RIS阵列的，以及，上述的目标波束索引具体为基站从反射波束集合和/或透射波束集合中选择的某一个波束对应的波束索引，也即是，上述的目标波束索引实质为RIS阵列所支持的反射波束和/或透射波束中某一波束的波束索引。
以及，在本公开的一个实施例之中，一个时隙位置信息对应至少一个目标波束索引，时隙位置信息用于指示：对应的目标波束索引所对应的目标波束的使用时隙的位置。
进一步地，在本公开的一个实施例之中，RIS阵列确定至少一个时隙位置信息的方法可以包括以下至少一种：
获取基站发送(例如通过信令发送)的至少一个时隙位置信息；

再进一步地，在本公开的一个实施例之中，RIS阵列可以被配置为周期性反射波束和/或周期性透射波束；在本公开的另一个实施例之中，RIS阵列也可以被配置为非周期性反射波束和/或非周期性透射波束。以及，在本公开的一个实施例之中，当RIS阵列的配置不同，时隙位置信息所包括的内容也不相同，其中，关于不同配置下时隙位置信息所包括的内容的详细介绍会在后续实施例描述。
步骤103、根据入射波束的方向，确定目标波束索引对应的目标波束的相移矩阵，基于时隙位置信息和相移矩阵对基站发送的入射波束进行反射和/或透射操作。
其中，在本公开的一个实施例之中，根据入射波束的方向，确定目标波束索引对应的目标波束的相 移矩阵的方法可以包括：
步骤a、设定一初始入射角，基于该初始入射角确定RIS阵列支持的各个反射波束和/或各个透射波束对应的初始相移矩阵。
其中，在本公开的一个实施例之中，可以是在RIS阵列实际接收到基站发送的入射波束之前，设定该初始入射角。该初始入射角可以为任一角度。示例的，在本公开的一个实施例之中，该初始入射角可以为0°。
以及，在本公开的一个实施例之中，上述的相移矩阵为：RIS阵列中的各个RIS单元的相位偏移角作为对角元素而构成的对角矩阵。其中，不同的相移矩阵可以使得RIS阵列按照不同的方向反射和/或透射入射波束。
进一步地，在本公开的一个实施例之中，RIS阵列支持的各个反射波束和/或透射波束对应的初始相移矩阵主要作用为：假定入射波束的入射方向为初始入射角，此时，若使得RIS阵列基于各个初始相移矩阵反射和/或透射该入射波束，即可对应得到RIS阵列所支持的各个反射波束和/或透射波束。
示例的，在本公开的一个实施例之中，假设RIS阵列支持一反射波束1和透射波束2，其中，该反射波束1的反射方向为a、对应初始相移矩阵1；透射波束2的透射方向为b、对应初始相移矩阵2。此时，假定入射波束的入射方向为初始入射角的前提下，若使得RIS阵列基于初始相移矩阵1来反射入射波束，则可得到反射波束1；若使得RIS阵列基于初始相移矩阵2来透射入射波束，则可得到透射波束2。
步骤b、确定基站发送至RIS阵列的入射波束的实际入射角。
其中，在本公开的一个实施例之中，该实际入射角可能为上述的初始入射角。在本公开的另一个实施例之中，该实际入射角也可能不为上述的初始入射角。
步骤c、基于初始入射角和实际入射角调整目标波束索引对应的目标波束的初始相移矩阵以得到相移矩阵。
由上述内容可知，本公开的一个实施例之中，基站指示的目标波束索引对应的目标波束实质为RIS阵列支持的某一反射波束或透射波束。
以及，在本公开的一个实施例之中，基于目标波束的初始相移矩阵得到的目标波束的相移矩阵主要作用为：在入射波束的入射方向为实际入射角的情况下，若使得RIS阵列基于该相移矩阵反射和/或透射该入射波束，则可得到该目标波束。
进一步地，在本公开的一个实施例之中，调整初始相移矩阵的方法具体可以为：基于初始入射角和实际入射角之间的角度差来调整目标波束索引对应的目标波束的初始相移矩阵以得到上述目标波束的相移矩阵。
由此可知，通过执行上述步骤a-c即可确定出“在入射波束的入射方向为实际入射角的情况下，RIS阵列反射和/或透射该入射波束后能够得到目标波束的相移矩阵”。以及，在本公开的一个实施例之中，RIS阵列在确定目标波束索引对应的目标波束的相移矩阵之后，可以在时隙位置信息所指示的特定时隙上基于相移矩阵对基站发送的入射波束进行反射和/或透射操作以得到上述的目标波束，则使得RIS阵列实现了“在特定时隙上按照特定方向对入射波束进行反射和/或透射”的操作。
