Abstract

Des modes de réalisation de la présente invention concernent un procédé de configuration de ressources, un dispositif terminal, et un dispositif de réseau. Lorsqu'un dispositif de réseau configure un ensemble de ressources de commande (CORESET) spécifique à un UE et un CORESET commun pour un dispositif terminal, et que les deux CORESETcoïncident sur une ressource temps-fréquence, le dispositif terminal peut surveiller avec précision un PDCCH sur la ressource temps-fréquence où se produit la coïncidence. Le procédé comprend les étapes consistant à : recevoir des informations de configuration envoyées par un dispositif de réseau, les informations de configuration étant utilisées pour configurer au moins deux CORESET coïncidant partiellement ou complètement les uns avec les autres sur une ressource temps-fréquence, ainsi que des paramètres de configuration correspondant à chacun des deux CORESET ou plus, les paramètres de configuration correspondant à l'un quelconque des deux CORESET desdits deux CORESET étant différents; et surveiller, d'après les paramètres de configuration correspondant à un premier CORESET parmi les deux CORESET ou plus, un PDCCH sur la ressource temps-fréquence où se produit la coïncidence.
