Disclosed are a method and a device used in a node of wireless communication. A first node device for wireless communication includes: a first receiver to receive first information and to receive first signaling and second signaling; and a first transmitter to transmit a first signal in a target air-interface resource block, the first signal carrying a third bit block and a fourth bit block. The first bit block is used to generate the third bit block, the second bit block is used to generate the fourth bit block, and an output obtained after all bits in the third bit block and all bits in the fourth bit block are subjected to a first channel coding is used to generate the first signal.
