摘要： A method and a device in a UE and a base station for wireless communication are disclosed. The UE monitors a first sequence in a first time window. If the first sequence is detected in the first time window, performs a blind detection of a first signaling on K1 alternative RE set(s); the first signaling occupies one of K1 alternative RE set(s) in time-frequency domain, each RE included in K1 alternative RE set(s) belongs to an alternative time-frequency resource pool in a second time window in time domain. The first sequence is used for determining a start time of the alternative time-frequency resource pool in the second time window. The disclosure determines the start time of the alternative time-frequency resource pool by using the first sequence, increasing transmitting opportunities of control signalings without increasing number of times of blind detections, improving spectrum efficiency and overall system performance on unlicensed spectrum.

摘要： The present disclosure provides a method and a device in a first node for wireless communication. The first node first performs a monitoring on first-type signalings, in which K1 first-type signalings are detected; and then transmits a first radio signal in a first time-frequency resource set; each of the K1 first-type signalings is associated to the first time-frequency resource set; a first signaling is a last first-type signaling of the K1 first-type signaling; the first radio signal is used for determining the receiving of first-type signaling(s) associated to the first time-frequency resource set before the first signaling; or is used for determining the decoding of bit blocks scheduled by the K1 first-type signalings. With the above-mentioned designs, the present disclosure manages to address missed detection of sidelink scheduling signaling caused when a data receiver sends NACK-only feedback in V2X, thereby further improving the entire system performance.
