Abstract: Disclosed is a method for a first terminal, which supports a sidelink, to transmit signals in a wireless communication system. Specifically, the method may comprise: a step for receiving a sidelink synchronization signal (SLSS) from a second terminal; a step for acquiring information about a subframe boundary time point for timing synchronization, and information about a propagation delay time; and a step for transmitting a sidelink signal to the second terminal on the basis of the subframe boundary time point and a timing advance (TA) that is twice the length of the propagation delay time.

Abstract: The present disclosure provides a method for receiving a synchronization signal/physical broadcast channel (SS/PBCH) block by a terminal in an unlicensed band. Particularly, the method may comprise: receiving an SS/PBCH block including an SS and a PBCH; detecting an index of a demodulation reference signal (DMRS) sequence for the PBCH; and on the basis of the index of the DRMS sequence, acquiring information relating to a time when an index of the SS/PBCH block and the SS/PBCH block are received, wherein the number of indices of the SS/PBCH block is smaller than or equal to the number of indices of the DMRS sequence, and the indices of the SS/PBCH block are cyclically mapped to the indices of the DMRS sequence.
