1. A method for performing wireless communication by a first device, the method comprising:
receiving a first physical sidelink control channel (PSCCH) or a first physical sidelink shared channel (PSSCH) including information related to a second synchronization source from a second device;
determining synchronization with the second device based on the information related to the second synchronization source; and
performing synchronization with the second device based on a reference signal on the first PSCCH or the first PSSCH,
wherein the second synchronization source includes a synchronization source having a highest priority pre-configured for the second device.
