Abstract

La présente invention concerne un procédé de détection d'informations de commande, un procédé de transmission d'informations de commande, un dispositif terminal et un dispositif de réseau. Le procédé de détection d'informations de commande comprend les étapes suivantes : un dispositif terminal reçoit des informations de configuration, et détermine, selon les informations de configuration, une première ressource de commande à l'intérieur d'une première porteuse et une seconde ressource de commande à l'intérieur d'une seconde porteuse, la première ressource de commande et la seconde ressource de commande étant utilisées pour transmettre des informations de commande et les informations de commande étant utilisées pour planifier un canal physique; si la première ressource de commande chevauche la seconde ressource de commande, le dispositif terminal détecte les informations de commande dans la première ressource de commande ou la seconde ressource de commande. Des modes de réalisation de la présente demande peuvent éviter des détections répétées d'un terminal.
