Abstract

Method and a device in UE and base station for wireless communication. A first node receives a first signaling; transmits a first signal in a first time pool, and transmits a second signal in a second time pool. The first signaling is used to determine K time windows; the first time window and the second time window are respectively two time windows that are adjacent among the K time windows, the first time window and the second time window being respectively associated with a first reference signal and a second reference signal; whether a first condition set is satisfied is used to determine whether the first time pool comprises all multicarrier symbols in the first time window and/or whether the second time pool comprises all multicarrier symbols in the second time window. The above method satisfies the request for processing time of beam handover and improves the resource utilization ratio.
