Abstract

La présente invention concerne un procédé de planification de ressource, un dispositif terminal et un dispositif côté réseau. Le procédé comprend les étapes suivantes : un dispositif terminal envoie des premières données de plan utilisateur à un dispositif côté réseau, les premières données de plan utilisateur transportant des informations d'état d'application concernant le dispositif terminal, les informations d'état d'application étant utilisées pour caractériser l'état de fonctionnement d'une application du dispositif terminal; et le dispositif terminal acquiert, à partir du dispositif côté réseau, une ressource temps-fréquence planifiée par le dispositif côté réseau pour le dispositif terminal en fonction des informations d'état d'application. Selon le procédé de la présente invention, il n'est pas nécessaire de transférer des informations d'état d'application sur une couche RRC, ce qui permet d'améliorer l'efficacité de planification de ressource d'un dispositif côté réseau, et en même temps, il n'est pas nécessaire pour un système d'exploitation de terminal ou un dispositif terminal et une puce de bande de base du dispositif côté réseau de développer une version d'un canal de transmission ou une interface de transmission allant du système d'exploitation à la couche RRC, ce qui permet de réduire le coût de développement du dispositif terminal.
