Abstract

L'invention concerne un procédé d'émission de canal, un procédé de réception de canal, un dispositif terminal, et un dispositif de réseau. Le procédé comporte les étapes consistant à: recevoir des données émises par un dispositif de réseau; après la dernière position de symbole occupée par les données, déterminer une ressource cible; et envoyer un canal cible de commande de liaison montante au dispositif de réseau via ladite ressource cible. Dans les modes de réalisation de la présente invention, après avoir reçu les données émises par le dispositif de réseau, le dispositif terminal peut directement déterminer une ressource cible pour l'envoi d'un canal cible de commande de liaison montante après la dernière position de symbole occupée par les données, évitant ainsi de configurer spécifiquement un domaine pour indiquer la ressource cible dans une signalisation de commande, comprimant la taille de la signalisation de commande, et accroissant la fiabilité de la signalisation de commande.
