Abstract

L'invention concerne un procédé permettant de recevoir un signal par un équipement d'utilisateur dans un système de communication sans fil prenant en charge une liaison latérale, et un dispositif associé , selon divers modes de réalisation. L'invention concerne un procédé de réception d'un signal par un équipement utilisateur dans un système de communication sans fil prenant en charge une liaison latérale, et un dispositif associé, le procédé comprenant les étapes consistant à : détecter une région de chevauchement dans laquelle une première partie de bande passante (BWP) et une seconde BWP peuvent être configurées ; transmettre, sur la base de la détection de la région de chevauchement, d'informations concernant une première ressource de réception attribuée à la première BWP, et une seconde ressource de réception attribuée à la seconde BWP ; et recevoir un signal dans au moins l'une de la première ressource de réception et de la seconde ressource de réception, la première ressource de réception et la seconde ressource de réception étant attribuées sur la base du fait que le domaine fréquentiel de la première BWP et le domaine fréquentiel de la seconde BWP sont adjacents.
