Abstract

L'invention concerne un procédé d'attribution de ressource et un équipement connexe. Ce procédé d'attribution de ressource comprend : lors de la création d'un premier paquet de données d'un message de sensibilisation à la coopération (CAM) par un équipement terminal utilisateur de véhicule (V-UE), si une ressource cible pouvant transmettre le premier paquet de données CAM a été attribuée par une station de base, la transmission, par le V-UE, du premier paquet de données CAM directement sur la ressource cible de façon à garantir efficacement un volume de données pour une communication entre la station de base et le V-UE ; et, si la ressource cible n'est pas attribuée par la station de base, la création, par le V-UE, d'un rapport d'état de mémoire tampon de véhicule (BSR-V) pour que la station de base puisse attribuer la ressource cible en fonction d'un intervalle de création du premier paquet de données CAM, ce qui permet à la station de base d'attribuer la ressource cible selon l'intervalle de création du premier paquet de données CAM même lorsqu'une ressource précédemment attribuée par la station de base n'est pas applicable en raison de changements de l'état de conduite d'un véhicule et de la taille du paquet de données CAM.
