Method and device in nodes used for wireless communication

A second communication node for wireless communications, comprising:

• a second receiver, receiving a first signaling, the first signaling being used to determine a first identity (ID) and a first distance, the first ID is a zone ID;
• a third receiver, receiving a first signal, the first signaling also being used to determine time-frequency resources occupied by the first signal;
• and
• a third transmitter, transmitting a second signal, or cancelling transmission of the second signal, the second signaling being used to indicate that the first signal is not correctly received by the third receiver;
• wherein the first ID is used to determine X zones, X being a positive integer greater than 1, and any two of the X zones are orthogonal;
• the X zones respectively comprise X characteristic geographic locations;
• a geographic location of the second communication node is used to determine a reference geographic location;
• when a distance between one of the X characteristic geographic locations and the reference geographic location is not greater than the reference distance and the first signal is not correctly received, the second signal is transmitted, otherwise the second signal is cancelled.
