Abstract

La présente invention concerne un procédé et un appareil de configuration de capacité multiporteuse d'un équipement utilisateur, ainsi qu'un procédé et un appareil de configuration d'informations multiporteuses d'un équipement utilisateur. Le procédé de configuration de capacité multiporteuse d'un équipement utilisateur comprend les étapes suivantes: un équipement utilisateur (UE), configuré en mode double porteuse de liaison montante et double porteuse de liaison descendante simultanément, configure des informations de capacité de nombre de porteuses de liaison descendante accepté par l'UE; et ledit UE envoie lesdites informations de capacité de nombre de porteuses de liaison descendante au contrôleur de réseau radio. La présente invention constitue une solution au problème de l'excès d'interférence entre la liaison montante et la liaison descendante causé par un intervalle trop faible entre la liaison montante et la liaison descendante rencontré dans l'état de la technique et améliore par conséquent les performances de réception.
