Abstract: Disclosed is a method for transmitting a primary synchronization signal (PSS) by a base station in a wireless communication system. In particular, the method may comprise the steps of: dividing one symbol into multiple periods; generating multiple sequences for the PSS, the number of which is identical to the number of the multiple periods; and mapping the multiple sequences to the one symbol divided into the multiple periods, and transmitting the multiple sequences.

Abstract: Disclosed is a method for transmitting, by a terminal supporting a sidelink, a sidelink synchronization signal block (S-SSB) in a wireless communication system. Specifically, the present disclosure comprises transmitting, from a specific slot, an S-SSB including a primary sidelink synchronization signal (PSSS), a secondary sidelink synchronization signal (SSSS), and a physical sidelink broadcast channel (PSBCH), wherein the PSBCH is mapped to first orthogonal frequency division multiplexing (OFDM) symbols included in the specific slot, and the first OFDM symbols are located after second OFDM symbols for the SSSS.
