Therefore, when the sending resource pool changes, V2X terminal devices need to perform sensing again on the changed sending resource pool.

Abstract

La présente invention concerne un procédé et un appareil de configuration de ressources. Le procédé de configuration de ressources consiste : à générer un premier message, le premier message comprenant des informations d'indication, les informations d'indication étant utilisées pour indiquer des premières informations auxquelles une ressource V2X d'une première cellule est applicable, et les premières informations étant des informations de cellule et/ou des informations de fréquence ; et à envoyer ou diffuser le premier message dans la première cellule. Dans les modes de réalisation de la présente invention, des cellules ou des fréquences auxquelles une ressource V2X est applicable sont indiquées au moyen d'un premier message, de telle sorte que, lors de la réalisation d'une resélection de cellule ou d'une commutation de cellule, un dispositif terminal peut clairement déterminer à quelles cellules ou fréquences la ressource V2X peut continuer à être applicable. Si ces cellules font l'objet d'une resélection ou d'une commutation, le dispositif terminal n'a pas besoin d'acquérir une ressource V2X de ces cellules, il peut utiliser directement une ressource V2X d'anciennes cellules, et il n'a pas naturellement besoin d'effectuer une détection sur la ressource V2X, ce qui permet de réduire un processus de fonctionnement du dispositif terminal et de réduire la consommation d'énergie du dispositif terminal ; de plus, étant donné qu'il n'est pas nécessaire d'utiliser un groupe de ressources de transmission exceptionnel, les performances de transmission sont améliorées.
