Abstract

La présente invention concerne un procédé et un dispositif de transmission d'informations de commande de liaison descendante (DCI), et un support d'enregistrement. Le procédé comprend : dans une unité de temps, sur la base d'un ordre de priorité prédéfini, la détection et la réception d'au moins un élément d'une pluralité d'éléments de DCI envoyés par une station de base, l'ordre de priorité étant un ordre selon lequel un terminal détecte et reçoit différents types de DCI dans une unité de temps, et la pluralité d'éléments de DCI comprend au moins des DCI de diffusion ; et en réponse à la détermination du fait qu'une pluralité d'éléments de DCI ont été détectés et reçus dans l'unité de temps ou que le nombre total d'éléments des DCI détectées et reçues atteint un nombre maximal d'éléments de DCI prises en charge pour être détectées et reçues par le terminal dans une unité de temps, l'arrêt de la détection et la réception de DCI dans l'unité de temps. Selon la présente invention, de multiples types de DCI peuvent être transmis, le problème selon lequel des comportements de terminal sont imprévisibles est évité, le terminal et la station de base peuvent être cohérents dans la compréhension de l'envoi et de la réception de données, et une dégradation de performance de système est évitée.
