Abstract

La présente invention concerne un procédé et un dispositif permettant de rapporter des informations d'état de canal (CSI). Le procédé comprend les étapes suivantes : un dispositif de terminal rapporte des premières informations CSI à l'aide d'un canal de commande de liaison montante physique dans un premier format à un premier moment, le canal de commande de liaison montante physique dans le premier format pouvant transporter les premières informations CSI ; le dispositif de terminal rapporte des secondes informations CSI à l'aide d'un canal de commande de liaison montante physique dans un second format à un second moment, le canal de commande de liaison montante physique dans le second format pouvant transporter les secondes informations CSI et le canal de commande de liaison montante physique dans le premier format étant différent du canal de commande de liaison montante physique dans le second format. L'exigence de rapport d'informations CSI lors d'une amélioration d'informations CSI peut être satisfaite à l'aide du procédé décrit dans la présente invention.
