Method and device for wireless communication

A second node for wireless communications, comprising:

• a second transmitter, transmitting a first radio signal, first information and second information;
• and
• a second processor, processing interferences from a second radio signal, the second radio signal being transmitted in a first target slot;
• wherein the first radio signal is used to indicate a synchronization timing of a first time window, the first time window comprises a plurality of slots, and the first information indicates a first slot out of the first time window;
• the second information indicates a first time offset;
• the first target slot is advanced by a second time offset compared with the first slot;
• the second time offset is related to a first residual time offset, a sum of the first residual time offset plus L1 first time length(s) is equal to the first time offset, L1 being a positive integer;
• the first residual time offset does not exceed the first time length;
• the second time offset does not exceed 2 times the first time length.
