Abstract

La présente divulgation concerne un procédé et un appareil de surveillance d'un PDCCH, ainsi qu'un dispositif et un support de stockage. Le procédé consiste à envoyer des données et/ou une signalisation à un dispositif de réseau et à surveiller dans une fenêtre de réponse un canal physique de commande de liaison descendante (PDCCH) qui est identifié par un identifiant temporaire de réseau radio (RNTI) spécifique et est envoyé par le dispositif de réseau. La présente divulgation peut réduire la consommation d'énergie d'un terminal surveillant le PDCCH et économiser des ressources.
