Abstract

La présente invention concerne un procédé, un dispositif et un système de transmission d'informations de commande. Le procédé comprend les étapes suivantes : un dispositif côté réseau paramètre des informations de commande selon un premier mode ; le dispositif côté réseau informe un dispositif terminal du premier mode pour paramétrer les informations de commande ; et le dispositif côté réseau envoie les informations de commande au dispositif terminal. Selon le procédé de transmission d'informations de commande décrit dans les modes de réalisation de la présente invention, au moyen du dispositif côté réseau paramètre des informations de commande selon un premier mode, informe le dispositif terminal du premier mode et envoie les informations de commande de ce dernier, le dispositif terminal peut obtenir, selon le premier mode, la position et la taille d'une ressource temps-fréquence occupée par un message de commande dans des informations de commande à divers niveaux de couverture, ce qui permet d'acquérir, à partir des informations de commande, un message de commande à un niveau de couverture avec les informations de commande appartenant à ce dernier, et améliore le taux d'utilisation des ressources temps-fréquence.
