Abstract

L'invention concerne des procédés, des systèmes et des dispositifs de communication sans fil. Un équipement utilisateur (UE) peut recevoir une configuration de répétitions permettant des répétitions de canal de commande de liaison descendante associées à un bloc d'informations de système (SIB) provenant d'une station de base. Sur la base de la configuration de répétitions, l'UE peut surveiller des informations de commande de liaison descendante (DCI) associées au SIB pendant une ou plusieurs des répétitions de canal de commande de liaison descendante pendant une période de transmission. Sur la base de la configuration de répétitions, l'UE peut par exemple combiner les répétitions de canal de commande de liaison descendante en utilisant les mêmes paramètres (par exemple un format des DCI, un emplacement dans un ensemble de ressources de commande (CORESET), un niveau d'agrégation et une occasion de surveillance) ou en utilisant une configuration de couche supérieure (par exemple des ressources temps- fréquence supplémentaires). Dans certains cas, l'UE peut recevoir les DCI sur la base de la surveillance des répétitions de canal de commande de liaison descendante. L'UE peut recevoir le SIB provenant de la station de base sur la base des DCI.
