1. A method performed by a user equipment, the method comprising:
receiving system information from a base station, the system information including time division duplexing (TDD) configuration information;
selecting a synchronization source from a plurality of sources, including the base station and another user equipment, based on a priority criterion, wherein a priority of the base station is higher than a priority of the other user equipment;
transmitting sidelink communication system information, including sidelink TDD configuration information, based on the synchronization source; and
performing a sidelink communication based on the synchronization source, wherein:
the sidelink communication system information further includes indication information indicating the synchronization source selected by the user equipment, and
the indication information is indicated by at least one of an indication field in the sidelink communication system information, physical sidelink broadcast channel (PSBCH) scrambling or generation of scrambling sequences, and demodulation reference signal (DMRS) sequences for a PSBCH channel estimation.
