1. A method for performing synchronization in a wireless communication system, the method performed by a user equipment (UE) and comprising:
receiving synchronization information from a specific UE, wherein the synchronization information indicates a specific synchronization source; and
performing synchronization with the specific synchronization source based on the synchronization information,
wherein the specific synchronization source is in a synchronization relationship with the specific UE,
wherein the synchronization information indicates a specific synchronization quality, and the specific synchronization quality is a synchronization quality between the specific UE and the specific synchronization source, and
wherein the UE performs synchronization with the specific synchronization source based on a value of the specific synchronization quality being higher than a value of the synchronization quality of the UE by a threshold or greater.
