Abstract

La présente invention concerne un procédé de planification de ressource, un procédé de transmission de données et un dispositif associé. Le procédé de planification de ressource comprend les étapes au cours desquelles : un dispositif côté réseau attribue un canal de commande destiné à au moins un canal de données, établit une relation de mappage entre un intervalle de temps de commande dans le canal de commande et une ressource en temps-fréquence de données dans le canal de données et informe les UE de la relation de mappage; lorsque le dispositif côté réseau doit planifier un UE cible, le dispositif côté réseau attribue des informations de localisation de ressource en temps-fréquence à l'UE cible; le dispositif côté réseau génère des informations de planification dudit au moins un canal de données en fonction des informations de localisation de ressource en temps-fréquence et de la relation de mappage, les informations de planification permettant à l'UE cible de transmettre des données en fonction des informations de localisation de ressource en temps-fréquence; et le dispositif côté réseau envoie les informations de planification à l'UE cible par l'intermédiaire du canal de commande. Le procédé de planification de ressource peut résoudre le problème de la planification de ressource dans un système FDD en semi-duplex et améliorer l'efficacité d'attribution de ressource du système FDD en semi-duplex.
