Method and apparatus for transmitting and receiving signals by side link terminal in wireless communication system

A second base station for use in a wireless communication system comprising:

• a memory;
• and
• a plurality of processors coupled to the memory,
• wherein at least one processor from among the plurality of processors is configured to:
• receive a second signal transmitted after lapse of a first interval by a user equipment (UE) having received a first signal from a first base station (BS), and
• receive a fourth signal transmitted after lapse of the first interval by the user equipment (UE) having received a third signal from the second base station (BS),
• wherein a synchronization error between the first base station (BS) and the second base station (BS) is determined based on a time point where the second base station (BS) receives the second signal and a time point where the second base station (BS) receives the fourth signal.
