目前，随着新的无线技术(New Radio，NR)的发展，高频信道衰减较快，为了保证网络覆盖范围，需要使用基于波束(Beam)的传输。为了减少信令数量，大多使用通用波束(Common Beam)进行传输，然而，相关技术中，待传输的通用波束组的数量不止一个，终端设备无法确定通用波束是用于具体哪个通用波束组的传输，基于通用波束传输的信号质量较差。
本申请的实施例中，终端设备可接收第一控制信令，第一控制信令用于确定目标通用波束，目标通用波束用于第一目标通用波束组内的成员的传输。也就是说，终端设备可根据第一控制信令，确定目标通用波束对应的第一目标通用波束组，目标通用波束用于第一目标通用波束组内的成员的传输。由此，终端设备可根据第一控制信令确定目标通用波束与第一目标通用波束组的对应关系，从而有助于提高基于通用波束传输的信号质量。
本申请的实施例中，终端设备还可确定第一目标通用波束组，可包括如下两种可能的实施方式：
方式1、第一目标通用波束组为第一控制资源集(Control Resource Set，CORESET)所属的通用波束组，第一CORESET用于传输承载第一控制信令的物理下行控制信道(Physical Downlink Control Channel，PDCCH)。
由此，第一目标通用波束组内的CORESET发送的PDCCH承载的第一控制信令只能用于确定第一目标通用波束组对应的目标通用波束。
本申请的实施例中，第一通用波束组中的PDCCH对应的CORESET的编号不为0，或者，CORESET的编号为0且CORESET对应的初始波束未使用随机接入过程获取，或者，第一控制信令在预设时间阈值内未成功解码，则终端设备还可接收第二控制信令，其中，第二控制信令中包括CORESET的标识和CORESET的标识对应的通用波束，进一步地，确定CORESET的标识对应的通用波束为第一通用波束组对应的通用波束。由此，该方法中终端设备还可根据第二控制信令，确定第一目标通用波束组对应的通用波束，通用波束用于第一目标通用波束组内的成员的传输。
需要说明的是，本申请的实施例中，对第二控制信令的类型不做过多限定。可选的，第二控制信令为媒体接入控制层控制单元(Medium Access Control Control Element，MAC CE)信令。方式2、第一控制信令中包括用于确定第一目标通用波束组的指示信息，此时终端设备可根据指示信息确定第一目标通用波束组。
