1. A method for delivering location information by a first terminal of a wireless communication system, the method comprising:
performing synchronization based on sidelink synchronization signal (SLSS), wherein the SLSS includes primary sidelink synchronization signal (PSSS) and secondary sidelink synchronization signal (SSSS);
determining one or more resource pools, wherein the one or more resource pools are configured by a base station based on resource allocation mode 1 for sidelink communication, or the one or more resource pools are determined by the first terminal based on resource allocation mode 2 for sidelink communication, wherein a resource pool includes a plurality of contiguous frequency resources in a frequency domain, and a set of slots in a time domain;
performing link connection with a second terminal, wherein absolute location information is delivered from the first terminal to the second terminal, and the absolute location information is information calculated based on a zone ID of the first terminal; and
performing, by the first terminal and the second terminal, sidelink communication based on the link connection,
wherein a preset region based on the zone ID of the first terminal and a zone index to each zone within the preset region is assigned, and relative location information corresponding to a location of the second terminal is received by the first terminal, and
wherein the relative location information is index information of a zone in which the second terminal is located based on the assigned zone index.
