Method and device in node for wireless communication

A second node for wireless communication, comprising:

• a second transmitter, to transmit a first signal;
• and
• a third receiver, to receive a first information block in a first time window;
• wherein the first information and a second information are both transmitted in the first time window, the first information block is used for determining whether the first signal is correctly received, and the second information block is used for determining whether a second signal is correctly received;
• a first field and a second field are used for indicating priorities of the first signal and the second signal respectively;
• transmit power values of physical layer channels carrying the first information block and the second information block are both a first power value;
• the priority of the first signal and the priority of the second signal are used together for determining a first expected power value, and the first power value is not greater than the first expected power value;
• the first field and the second field are both transmitted in a physical layer channel.
