相应地，终端设备接收该指示信息。
其中，该指示信息用于指示广播的MBS数据对应的VRB到PRB的映射方案。该映射方案包括交织映射和/或非交织映射。网络设备一般给终端设备指示VRB资源信息，具体的物理资源映射需要通过VRB映射到对应PRB后才能得到。

可以理解的是，接收到的相应的DCI对应的控制资源集，可以认为是调度MBS数据的 DCI格式4_0所关联的控制资源集，也可以认为是调度MBS数据的包含DCI格式4_0的PDCCH所关联的控制资源集。
当检测到高层参数searchSpaceLinking所指示的两个关联的搜索空间集中的两个候选PDCCH，且这两个关联的搜索空间集与不同的控制资源集关联，两个关联的控制资源集中的数量最小或者最小编号的控制资源集用于确定
