Method for transmitting and receiving signals in wireless communication system, and device supporting same

A user equipment (UE) for transmitting a Sidelink Synchronization Signal and Physical Sidelink Broadcast Channel Block (S-SS/PSBCH block) in a wireless communication system, the UE comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
• obtaining a first cyclic shift (CS) value among first CS values for a Primary Sidelink Synchronization Signal (PSSS) based on whether the UE is in-coverage or out-of-coverage;
• generating the PSSS based on the first CS value;
• generating a Secondary Sidelink Synchronization Signal (SSSS) by multiplying a first M-sequence and a second M-sequence;
• and
• transmitting, via the at least one transceiver, a S-SS/PSBCH block including the PSSS and the SSSS,
• wherein the first CS values are values such that intervals between each of the first CS values and each of second CS values for a Primary Synchronization Signal (PSS),
• wherein a first CS value based on the UE being in-coverage and a first CS value based on the UE being out-of-coverage are different from each other, and
• wherein the first M-sequence is based on CS value being 5, the second M-sequence is based on CS value being 1.
