The present disclosure provides a method and a device in a node for wireless communication. A first node receives first information; receives a first signaling, the first signaling being used for indicating a first symbol set; then operates K radio signals respectively in K symbol groups in the first symbol set. The first symbol set comprises a first symbol subset and a second symbol subset, the first information is used for indicating a type of each multicarrier symbol in the first symbol set, and the first information is used for determining the first symbol subset and the second symbol subset; any of the K symbol groups belongs to one of the first symbol subset and the second symbol subset; each of the K radio signals carries a first bit block, the K radio signals respectively correspond to K first-type parameters.
