1. A method by a first user equipment (UE) comprising:
forming a first link together with a second UE in a first frequency band;
estimating a second reception timing point related to a second link formed between a third UE and a fourth UE in a second frequency band, based on a synchronization signal and timing advance (TA) information broadcast by the third UE configured to use the second frequency band adjacent to the first frequency band; and
determining whether to change a reception timing point of a signal for the first link, based on a difference value between a first reception timing point related to the first link and the second reception timing point.
