Method and device in nodes used for wireless communication

A second node for wireless communications, characterized in comprising:

• a second transmitter, transmitting a first signaling, the first signaling being used to determine K time-frequency resource pools, K being a positive integer greater than 1;
• wherein a receiver for the first signaling comprises a first node, and the first node 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 a time offset corresponding to each time-frequency resource pool among the K time-frequency resource pools;
• a first time offset is one of the K time offsets that corresponds to the first time-frequency resource pool, and the first time offset is a value of a time offset between a start time of the first time-frequency resource set in time domain and a start time of the first time-frequency resource pool in time domain;
• the first signaling is transmitted in a cellular link, while the first signal is transmitted in a sidelink;
• the K time offsets are related to positional information for the first node.
