Abstract: The present disclosure provides a method and a device in a node for wireless communications. A first node receives a first signaling, the first signaling being used to determine K time-frequency resource pools; and transmits a first signal in a first time-frequency resource set; the first time-frequency resource set belongs to a first time-frequency resource pool, the first time-frequency resource pool being one of the K time-frequency resource pools; K time offsets respectively correspond to the K time-frequency resource pools, and the first signaling is used to determine the K time offsets corresponding to the K time-frequency resource pools; a first time offset corresponds to the first time-frequency resource pool. The present disclosure designs a first signaling to flexibly configure time-domain resources used for sidelink transmission, thus avoiding interferences between cellular link and sidelink in a system larger transmission delay.
