The application discloses a method and device used in a node for
wireless communication. A first
receiver receives a first information block and a first signaling set, the first signaling set includes a plurality of control signaling, and a first control signaling is one of the control signaling included in the first signaling set; a first
transmitter transmits a first PUCCH at a first transmission power; wherein a first reference HARQ-ACK bit quantity is used to determine the first transmission power; the first control signaling includes a first field; a first intermediate quantity is used to determine the first reference HARQ-ACK bit quantity, and the first intermediate quantity is linearly related to the value of the first field included in the first control signaling; the first signaling set includes a target signaling subset, the first intermediate quantity is linearly related to the number of control signaling included in the target signaling subset, and the first information block is used to determine whether the first control signaling belongs to the target signaling subset.
