Abstract

L'invention concerne un procédé de planification de ressources et un appareil de planification de ressources pour une communication de véhicule, ainsi qu'un terminal et une station de base. Le procédé de planification de ressources pour la communication de véhicule consiste à : acquérir un paramètre de configuration, attribué par une station de base, pour réaliser une planification semi-statique sur une liaison secondaire; en fonction du paramètre de configuration, déterminer une ressource temps-fréquence pour transmettre de façon périodique un message de communication de véhicule; et, sur la base de la ressource temps-fréquence, transmettre de façon périodique le message de communication de véhicule. Selon la solution technique de la présente invention, lorsqu'un terminal effectue un service V2V, une station de base peut configurer une ressource temps-fréquence pour le terminal en utilisant un mécanisme de planification semi-statique et les frais généraux d'un PDCCH peuvent ainsi être réduits, de sorte que plus de ressources soient utilisées par la station de base pour la planification d'autres terminaux, améliorant ainsi l'efficacité d'utilisation des ressources.
