Abstract

Lorsqu'une communication est réalisée dans une large bande de fréquence en utilisant de manière composite une pluralité de bandes de fréquence continues et/ou non continues (éléments de support), on transmet les données (informations) dans un dispositif de station mobile avec une suppression de puissance d'émission de façon à ce que celle-ci soit faible. Un dispositif de station de base affecte au dispositif de station mobile un premier canal de commande de liaison montante physique pour la transmission de premières informations de commande, et affecte au dispositif de station mobile une pluralité de seconds canaux de commande de liaison montante physique pour une transmission de secondes informations de commande avec une sous-trame identique à la sous-trame à laquelle le premier canal de commande de liaison montante physique est affecté. Le dispositif de station mobile sélectionne l'un quelconque de la pluralité de seconds canaux de commande de liaison montante physique, et transmet conjointement au dispositif de station de base les premières informations de commande et les secondes informations de commande ou les secondes informations de commande.
