Abstract

Une station de base peut sélectionner une configuration permettant d'ignorer une surveillance de PDCCH pendant une période de temps prédéterminée. La station de base peut transmettre, à un UE, et l'UE peut recevoir, en provenance de la station de base, la configuration permettant d'ignorer la surveillance de PDCCH. L'UE peut identifier si une première condition est satisfaite pendant la période de temps prédéterminée. La première condition peut être associée à une première fenêtre temporelle qui chevauche au moins en partie la période de temps prédéterminée. L'UE peut effectuer la surveillance de PDCCH si la première condition est satisfaite pendant la période de temps prédéterminée ou ignorer la surveillance de PDCCH si la première condition n'est pas satisfaite pendant la période de temps prédéterminée. La surveillance de PDCCH peut être ignorée sur la base de la configuration permettant d'ignorer la surveillance de PDCCH. La surveillance de PDCCH peut être ignorée pendant une partie de la période de temps prédéterminée qui ne chevauche pas la première fenêtre temporelle.
