The present disclosure provides a method and device in nodes used for wireless communication. A first node receives a first signaling, the first signaling is used to indicate a first symbol set; and then operates a first radio signal in only a first symbol group in the first symbol set. The first signaling is used to indicate scheduling information of the first radio signal; any multicarrier symbol in the first symbol group belongs to the first symbol set, and a number of multicarrier symbol(s) comprised in the first symbol group is not greater than a number of multicarrier symbol(s) comprised in the first symbol set; a target TDD configuration is used to determine a type of each multicarrier symbol in the first symbol set, the target TDD configuration is used to determine the first symbol group out of the first symbol set.
