Abstract

L'invention concerne un procédé de transmission de signal de commande en liaison descendante. Le procédé comprend les étapes suivantes : un dispositif terminal obtient des informations de configuration d'un signal de commande en liaison descendante ; le dispositif terminal détecte, sur la base des informations de configuration, le signal de commande en liaison descendante, la ressource occupée par le signal de commande en liaison descendante ayant une correspondance avec une ressource de transmission utilisée pour la transmission de données. L'invention concerne un autre procédé de transmission de signal de commande en liaison descendante, un dispositif terminal, un dispositif de réseau et un support de stockage.
