Abstract

L'ensemble de niveaux d'agrégation de ressources disponible pour former un message de canal de commande amélioré peut varier d'une sous-trame à une autre, en fonction du niveau de perforation dans les sous-trames transmises. Un procédé décrit dans la présente invention consiste à déterminer (2710) des membres d'un ensemble de niveaux d'agrégation utilisable pour agréger les sous-ensembles non en chevauchement d'éléments de ressources pour transmettre des données de commande sur la liaison descendante. Ladite détermination est basée sur un niveau de perforation devant être utilisé pour la transmission des données de commande sur la liaison descendante. Des données de commande sur la liaison descendante pour la sous-trame donnée sont mises en correspondance (2720) par rapport à un ou plusieurs sous-ensembles non en chevauchement d'éléments de ressources dans le ou les blocs de ressources temps-fréquence, en fonction d'un niveau d'agrégation sélectionné à partir de l'ensemble déterminé, et elles sont ensuite transmises (2730), dans le ou les sous-ensembles non en chevauchement d'éléments de ressources. Ce procédé peut être répété pour chacune de plusieurs sous-trames, la perforation pouvant varier d'une sous-trame à une autre.
