1. A method of transmitting a sidelink signal by a first user equipment (UE) in a communication system for supporting sidelink communication, the method comprising:
receiving resource configuration information related to a positioning reference signal (PRS);
receiving a first PRS based on the resource configuration information;
measuring an angle of arrival (AoA) based on the first PRS; and
transmitting the sidelink signal based on the first PRS and the measured AoA,
wherein the first UE determines a time resource region related to the sidelink signal based on a pattern of the first PRS, and determines a pattern of a second PRS included in the sidelink signal based on the measured AOA.
