1. A method in a first node for wireless communication, comprising:
monitoring a first signaling and a second signaling in a first time-frequency resource set; and
judging whether to transmit a first radio signal according to a monitoring result of the first signaling; and transmitting the first radio signal in a second time-frequency resource set, when judging to transmit the first radio signal;
wherein the second signaling is not correctly decoded in the first time-frequency resource set, a signaling format corresponding to the second signaling is used for scheduling of a data signal; and the first radio signal is used for indicating that a data signal scheduled by the second signaling is not correctly decoded; the first signaling includes a first Physical Sidelink Control Channel (PSCCH); the second signaling includes a second PSCCH; a physical layer channel occupied by the first radio signal includes a Physical Sidelink Feedback Channel (PSFCH); the first signaling is correctly decoded; the first signaling indicates Q1 node(s) from Q nodes, and the first node is one of the Q nodes; if the first node is one of the Q1 node(s), it is judged to transmit the first radio signal; otherwise, it is judged not to transmit the first radio signal; the Q is a positive integer greater than 1; and the Q1 is a positive integer not greater than the Q; any one of the Q nodes is one terminal, or any one of the Q nodes is one UE, or any one of the Q nodes is one vehicle; the Q nodes correspond to Q different identifiers respectively; the first signaling comprises Q bits, and the Q bits correspond to the Q different identifiers respectively; the Q nodes all belong to one given terminal group, the given terminal group corresponds to a given terminal group identifier, and a CRC sequence comprised in the first signaling is scrambled with the given terminal group identifier; Q is a positive integer greater than 1.
