Abstract

Sont décrits ici un procédé de transmission de ressources de canal, un appareil, un dispositif réseau, un terminal et un système. Le procédé comprend les étapes suivantes : un dispositif réseau envoie un canal de commande candidat à un dispositif terminal dans au moins un espace de recherche ; une relation d'association existe entre au moins un espace de recherche et au moins deux états d'indicateur de configuration de transmission, et une ressource occupée par le canal de commande candidat est déterminée selon un état d'indicateur de configuration de transmission correspondant au canal de commande candidat ainsi qu'un ensemble de ressources de commande correspondant à l'état d'indicateur de configuration de transmission correspondant au canal de commande candidat. La présente invention résout le problème technique de technologies apparentées dans lesquelles, en raison de l'obtention d'une configuration sur une ressource de domaine de fréquence pour un PDCCH en fonction du nombre de canaux candidats dans un espace de recherche, la détection effectuée par un UE sur un PDCCH sur ladite ressource de domaine de fréquence entraînera une incapacité ultérieure à recevoir correctement un PDCCH.
