Abstract

L'invention concerne un procédé, un dispositif et un système de planification de ressources. Le procédé comprend les étapes suivantes : une station de base reçoit une demande de planification semi-persistante de véhicule à infrastructure routière (V2X), envoyée par un équipement utilisateur de V2X sur une ressource prédéterminée (201) ; et la station de base prend connaissance de la taille d'un paquet de données demandé par l'équipement utilisateur de V2X selon la demande de planification semi-persistante V2X, et planifie une ressource V2X pour l'équipement utilisateur de V2X selon la taille du paquet de données demandé. Les modes de réalisation de la présente invention permettent de satisfaire à la faible latence requise par une communication V2X.
