Title
(EN) SYSTEM AND METHOD FOR BEAM MANAGEMENT
(ZH) 用于波束管理的系统和方法
Abstract
(EN)
A first apparatus may transmit, to a user equipment (UE), on a control channel, one or more indications of one or more beam indexes corresponding to one or more beams. The first apparatus may transmit, to the UE, one or more reference signals through the one or more beams corresponding to the one or more beam indexes. The reference signals may be used by the UE to select a best subarray and/or receive combiner for communication with the first apparatus.

(ZH)
第一装置可以在控制信道上,向用户设备(UE)发送对与一个或多个波束相对应的一个或多个波束索引的一个或多个指示。所述第一装置可以通过与所述一个或多个波束索引相对应的所述一个或多个波束,向所述UE发送一个或多个参考信号。所述参考信号可以被所述UE用来选择用于与所述第一装置的通信的最优子阵列和/或接收组合器。
