1. A method for transmitting, by a first apparatus, location information in a wireless communication system, the method comprising:
obtaining location information comprising i) an estimated distance between the first apparatus and a second apparatus, and ii) an accuracy of the estimated distance;
determining a periodicity of transmission of the location information based on the accuracy of the estimated distance, wherein the periodicity is determined to be longer as the accuracy increases, and determined to be shorter as the accuracy decreases;
comparing the accuracy of the estimated distance with a threshold; and
based on the accuracy of the estimated distance being lower than the threshold, transmitting the location information to the second apparatus with the determined periodicity,
wherein the method further comprises:
transmitting a physical sidelink control channel (PSCCH) to the second apparatus; and
transmitting a physical sidelink shared channel (PSSCH) related to the PSCCH to the second apparatus,
wherein the PSSCH includes sidelink control information (SCI),
wherein the SCI includes the location information,
wherein the first apparatus transmits sidelink synchronization signals to the second apparatus for synchronization,
wherein the sidelink synchronization signals comprise a sidelink primary synchronization signal (S-PSS) and a sidelink secondary synchronization signal (S-SSS), and
wherein the S-PSS, the S-SSS and a physical sidelink broadcast channel (PSBCH) form a sidelink synchronization signal block (S-SSB).
