PROCÉDÉ ET DISPOSITIF POUR DÉTERMINER UNE ID DE SESSION DE COUCHE PHYSIQUE DE LIAISON LATÉRALE DANS UN SYSTÈME DE COMMUNICATION SANS FIL

摘要

The present invention may provide a method for transmitting, by means of a terminal, feedback information in an NR V2X system. The method for transmitting feedback information may comprise: a step in which a first terminal performs a session establishment process with a second terminal on the basis of at least one of a unicast and a groupcast; a step in which the first terminal and the second terminal exchange ID information with each other during the session establishment process; and a step in which the first terminal and the second terminal complete session establishment. When the first terminal and the second terminal complete the session establishment, a physical layer ID representing the session may be determined.
