Abstract

L'invention concerne un procédé et un appareil permettant de transmettre des données de liaison montante. Ce procédé consiste, d'abord à recevoir une valeur de classement en provenance d'une station de base, ensuite à déterminer un mode d'envoi d'un terminal d'utilisateur en fonction de la valeur de classement, et enfin à envoyer les données vers un canal de liaison montante en utilisant le mode d'envoi déterminé. L'invention permet, par ses modes de réalisation, de s'affranchir partiellement de la baisse d'efficacité de la transmission en liaison montante dans la mesure où il est possible d'éviter que l'information d'indication prenne effet de façon asynchrone.
