Abstract
A method and device for wireless communication in a UE and a base station is disclosed. The UE receives M first-type reference signals respectively in M first-type air interface resources, receives a first wireless signal, and transmits first report information. A first spatial reception parameter is used for reception of the first wireless signal. The measurement of only M1 first-type reference signal(s) of the M first-type reference signals is used to generate the first report information. The selection of the M1 first-type reference signal(s) is associated with the first spatial reception parameter. The disclosure reduces signaling and feedback overhead associated with beam management and channel measurement.
