Abstract

L'invention concerne un procédé et un appareil de traitement de planification, un support de stockage, et un dispositif électronique. Le procédé de traitement de planification consiste à : démoduler des premières données d'utilisateur d'après des informations détectées d'un premier canal de commande de liaison descendante physique (PDCCH) et, durant la démodulation des premières données d'utilisateur, déterminer qu'il existe également une position de surveillance pour un second PDCCH ; et selon une politique prédéterminée, sélectionner l'une des opérations suivantes pour traitement : la réception des premières données d'utilisateur et l'arrêt de la détection aveugle du second PDCCH ; et l'exécution d'une détection aveugle sur le second PDCCH et l'arrêt de la réception des premières données d'utilisateur.
