Method and device in communication node used for wireless communication

A method in a second-type communication node used for wireless communications, comprising:

• transmitting first information and second information;
• monitoring a first radio signal in a first time window;
• and
• receiving a second radio signal when the first radio signal is detected;
• wherein the first information is used for determining a target time window, the second radio signal occupies a second time window in time domain, and the second information is used for determining at least one of whether the second time window belongs to the target time window or a relative position relationship between the second time window and the target time window;
• an end of the first time window is earlier than a start of the target time window, a radio resource occupied by the first radio signal is used for determining at least one of a frequency-domain resource occupied by the second radio signal, a code-domain resource occupied by the second radio signal or a Modulation and Coding Scheme employed by the second radio signal;
• the first information, the second information, the first radio signal and the second radio signal are all transmitted via an air interface;
• the first information comprises all or part of an RRC signaling, the second information comprises all or part of an RRC signaling;
• the code-domain resource occupied by the second radio signal refers to a scrambling sequence resource for generating the second radio signal;
• the second time window comprises a positive integer number of consecutive multicarrier symbol(s)e with a given Subcarrier Spacing (SCS).
