Abstract

La présente invention concerne un procédé, un équipement d'utilisateur, une station de base, un dispositif côté réseau, et un système de transmission de données. L'équipement d'utilisateur comprend : un premier module de transmission, pour transmettre des premières données de liaison montante sur une ressource de canal dédié amélioré commun (E-DCH commun) ; et un module de traitement, pour suspendre la transmission d'un DPCCH au terme de la transmission des premières données de liaison montante, mais sans libérer encore la ressource d'E-DCH commun. L'équipement d'utilisateur fourni par le mode de réalisation de la présente invention transmet un DPCCH et des données de liaison montante sur une ressource d'E-DCH commun attribuée par une station de base et, au terme de la transmission des données de liaison montante, l'UE suspend la transmission du DPCCH. L'interférence avec un autre équipement d'utilisateur dans une cellule est ainsi réduite et la capacité du système améliorée.
