METHODS FOR SUPPORTING INTERNAL COMMUNICATION IN WIRELESS COMMUNICATION SYSTEMS

Abstract

The invention relates to a method of supporting, by a user device (UE), sideline communication in a wireless communication system. The method of supporting, by a UE, sideline communication in a wireless communication system may include the following steps: receiving a coordination request from a transmitting UE (Tx UE); generating a coordination message based on the coordination request; and transmitting the generated coordination message to the Tx UE. Here, the coordination request may include 1 bit of information and the coordination request may be received based on at least one of the physical resource sets of the physical sideline feedback channel (PSFCH), sideline control information format (SCI), periodic redundancy check scrambling (CRC), and demodulation reference signal sequence (DMR.S), and the Tx UE may perform resource re-selection based on the coordination message.
