步骤2:数字域信道信息反馈
基站想使用TRP_B1来接收SRS,基站给UE发送SRS配置信息,其中包括如下信息:CSI-RS资源1。
UE根据基站的配置信息推断出基站想用TRP_B1来接收SRS,因此UE采用UE_B1来发送SRS。
步骤3:CSI-RS的发送和CSI测量反馈
基站采用TRP_B1接收SRS,估计出数字信道信,并计算数字赋形权值P,然后基站采用模拟波束TRP_B1和数字赋形权值P来发送波束赋形的CSI-RS。
UE测量波束赋形的CSI-RS并反馈CSI。
步骤4:基站使用模拟数字混合波束赋形进行数据传输
基站采用模拟波束TRP_B1、数字赋形权值P,并结合步骤3 UE反馈CSI进行数据发送。
