Abstract

La présente invention concerne un procédé et un dispositif de transmission en liaison montante. Un procédé associé au côté dispositif terminal correspondant fait appel : conformément à une manière d'attribution ayant fait l'objet d'un accord préalable avec un dispositif de réseau ou à des informations de configuration envoyées par le dispositif de réseau, à la détermination de sous-trames de liaison montante occupées par chaque bande de fréquences d'une agrégation de porteuses d'un ensemble de sous-trames de liaison montante partagé, les sous-trames de liaison montante occupées par chaque bande de fréquences étant différentes les unes des autres, et l'ensemble de sous-trames de liaison montante partagé étant un ensemble de sous-trames de liaison montante ayant le même numéro de série de sous-trame d'une structure de trame utilisée pour chaque bande de fréquences ; et à l'envoi de données de liaison montante sur chaque sous-trame de liaison montante de l'ensemble de sous-trames de liaison montante partagé au moyen de la bande de fréquences occupant la sous-trame de liaison montante. La solution technique des modes de réalisation de la présente invention attribue les sous-trames de liaison montante de l'ensemble de sous-trames de liaison montante partagé pour chaque bande de fréquences, de façon à garantir le fait que des données de liaison montante soient envoyées sur une bande de fréquences d'une sous-trame de liaison montante, garantissant ainsi qu'une liaison montante n'assure qu'une transmission en liaison montante d'un terminal à capacité d'envoi sur une seule bande de fréquences dans un scénario CA inter-bande.
