Patent ID: 11528704

Abstract:
The disclosure provides method and device in used in User Equipment (UE) and base station for wireless communication. The UE receives a first signaling in a first time window, then receives a second signaling group in a second time window, the second signaling group being used for indicating K2 candidate frequency band resource(s), and monitors a third signaling in a second frequency band resource; the second signaling group includes Q1 physical layer signaling(s); the second frequency band resource is one of the K2 candidate frequency band resource(s), and a first field in the first signaling is used for determining the second frequency band resource from the K2 candidate frequency band resource(s). Through determining the second frequency band resource from the K2 candidate frequency band resource(s) dynamically, the disclosure improves frequency band utilization on unlicensed spectrum under the premise of guaranteeing scheduling flexibility, thereby improving overall performances of the system.
