Abstract

La présente invention concerne un procédé et un appareil de communication de liaison latérale, ainsi qu'un dispositif de communication et un support de stockage, qui se rapportent au domaine technique des communications mobiles. Le procédé est appliqué à un dispositif terminal de réception et consiste à : déterminer un premier ensemble de ressources, le premier ensemble de ressources faisant partie d'un groupe de ressources de communication de liaison latérale pour transmettre un canal de commande de liaison latérale physique (PSCCH) ; et détecter et recevoir le PSCCH sur la base du premier ensemble de ressources. Ceci limite la position d'une ressource détectée et reçue par un dispositif terminal de réception, ce qui permet d'économiser de l'énergie pendant une liaison latérale du dispositif terminal de réception.
