Abstract

La présente invention concerne un procédé, un appareil et un dispositif de communication, et un support de stockage. Le procédé comprend les étapes suivantes: déterminer une capacité de détection aveugle de chaque fenêtre temporelle, la longueur de la fenêtre temporelle étant inférieure à un créneau, et la capacité de détection aveugle comprenant: le nombre maximal de canaux de commande de liaison descendante physique (PDCCH) candidats et le nombre maximal d'éléments de canal de commande (CCE) non superposés ; et effectuer une détection aveugle de PDCCH selon la capacité de détection aveugle de chaque fenêtre temporelle. Par conséquent, le réglage de la longueur de chaque fenêtre temporelle pour être inférieure à un créneau réduit l'intervalle de définition de la capacité de détection aveugle, et répond aux exigences réelles pour un service à faible latence et une fiabilité élevée.
