Abstract

Dans ses modes de réalisation, la présente invention se rapporte à un procédé et à un appareil adaptés pour configurer une pluralité de porteuses. Le procédé selon l'invention comprend les étapes suivantes : un équipement de contrôle de station de base reçoit des premières données de configuration de canal de commande partagé à haut débit (HS-SCCH, High Speed Shared Control Channel) ainsi que des données de désignation pour au moins deux porteuses dans l'état non CELL_DCH qui sont envoyées par une station de base, les données de désignation étant utilisées pour désigner un HS-SCCH qui se trouve parmi les HS-SCCH identifiés dans les premières données de configuration de HS-SCCH et qui peut être utilisé pour la transmission de données sur la liaison descendante pour une pluralité de porteuses ; et l'équipement de contrôle de station de base transmet des secondes données de configuration de HS-SCCH pour au moins deux porteuses dans l'état non CELL_DCH à un équipement d'utilisateur (UE, User Equipment) sur la base des données de désignation, le HS-SCCH identifié par les secondes données de configuration de HS-SCCH correspondant au HS-SCCH qui se trouve parmi les HS-SCCH identifiés dans les premières données de configuration de HS-SCCH et qui peut être utilisé pour la transmission de données sur la liaison descendante pour une pluralité de porteuses. De cette manière, quand l'UE se trouve dans l'état non CELL_DCH, l'UE est apte à exécuter une réception de données sur la liaison descendante pour une pluralité de porteuses sur la base des secondes données de configuration de HS-SCCH et de la programmation de la station de base. La solution technique de la présente invention permet ainsi d'améliorer la fiabilité de la transmission de données.
