The present disclosure provides a method and device in nodes used for wireless communication. A first node receives a first signaling; transmits a second signaling, drops transmitting a first signal on a first radio resource block; or, drops transmitting a second signaling, transmits a first signal on a first radio resource block; the first signaling is used for a request for transmitting the first signal on the first radio resource block; and the first signaling is used to indicate a first radio resource block. Since a working status of the first node is timely informed, the present disclosure effectively solves the communication problems between peer nodes in the distributed system, thus reducing unnecessary signaling overhead and resource waste.
