Abstract

Les modes de réalisation de la présente invention portent sur un procédé, un appareil et un système de commande de porteuses auxiliaires. Le procédé comprend les étapes suivantes : une signalisation de canal de commande partagé à haut débit (HS-SCCH), dont le mode de signalisation est le mode à plusieurs porteuses et dont le contenu de signalisation comprend au moins deux bits reconnaissables, est reçue ; selon la relation de correspondance entre les bits reconnaissables et les porteuses auxiliaires, la commande des porteuses auxiliaires correspondant aux bits reconnaissables est effectuée. Lorsque le mode de signalisation de la signalisation HS-SCCH reçue en provenance d'un nœud B (NB) par un équipement utilisateur (UE) est le mode à plusieurs porteuses, l'équipement utilisateur peut effectuer une commande d'activation/désactivation des porteuses auxiliaires correspondant aux deux, ou plus, bits reconnaissables contenus dans le contenu de signalisation de la signalisation HS-SCCH simultanément selon la relation de correspondance entre les bits reconnaissables et les porteuses auxiliaires acquise à l'avance. L'invention peut permettre la commande simultanée des porteuses auxiliaires de l'équipement utilisateur dans le système à plusieurs porteuses (deux porteuses auxiliaires ou plus) et améliorer la flexibilité de la configuration du système à plusieurs porteuses.
