Abstract

La présente invention est applicable au domaine des communications. La présente invention concerne un procédé et un appareil de planification de données de liaison montante dans une agrégation de porteuses. Selon l'invention, le procédé fait appel : à l'envoi d'une requête de planification à une macro station de base par l'intermédiaire d'un canal de commande de liaison montante physique ; et à la réception d'un message d'autorisation de données de liaison montante envoyé par une station de base qui déclenche l'envoi de données de liaison montante, et à l'envoi de données, conformément à la requête de planification, à la station de base qui déclenche l'envoi de données de liaison montante. Selon les modes de réalisation de la présente invention, un équipement utilisateur véhicule, dans une requête de planification, un message d'indication spécifiant une station de base qui déclenche l'envoi de données de liaison montante, de sorte qu'une macro station de base envoie la requête de planification à la station de base qui déclenche l'envoi de données de liaison montante, la station de base qui déclenche l'envoi de données de liaison montante envoie une autorisation de données de liaison montante à l'équipement utilisateur, et l'équipement utilisateur envoie directement les données à la station de base qui déclenche l'envoi de données de liaison montante ; par conséquent, la macro station de base ne doit envoyer que la requête de planification à la station de base qui déclenche l'envoi de données de liaison montante, et les données sont envoyées directement par l'équipement utilisateur, ce qui réduit la charge et le coût pour un dispositif de réseau.
