Patent ID: 11533139

Abstract:
A method and a device in a User Equipment (UE) and a base station for wireless communications are disclosed by the present disclosure. A first node receives T first-type radio signals; performs T access detections respectively on T sub-bands and transmits T second-type radio signals respectively in T time-frequency resource blocks; and performs Q energy detection(s) respectively in Q time sub-pool(s) on a first sub-band, through which Q detection value(s) is (are) obtained. The T sub-bands each comprise at least one same frequency point, or the T sub-bands belong to a same carrier; at least one of the T sub-bands is different from the first sub-band; the selection of the reference time-frequency resource block is related to at least one between the first sub-band and the reference sub-band; the first node is a base station, or the first node is a UE.
