1. A method of performing sidelink transmission by a user equipment (UE) in a wireless communication system, the method comprising:
selecting a cell or a global navigation satellite system (GNSS) as a synchronization reference; and
performing the sidelink transmission using the selected synchronization reference,
wherein, based on the UE being in a coverage of the cell, and a time division duplex (TDD) frame structure being applied, a first offset is applied to the sidelink transmission, and
wherein, based on the UE using the GNSS as the synchronization reference, a second offset used for calculating a D2D frame number (DFN) is applied to the sidelink transmission in addition to the first offset.
