Abstract

L'invention concerne un procédé, un dispositif et un système qui permettent de régler un rapport de signalisation, qui se rapportent au domaine technique des applications de réseau de communication et qui permettent d'améliorer la continuité de services de communication lorsqu'un équipement utilisateur (UE) se déplace parmi des cellules. Le procédé comprend les étapes suivantes : une macro-station de base (MeNB) envoie un premier message d'indication à un UE (101), le premier message d'indication étant utilisé pour indiquer à l'UE de renvoyer conjointement des informations de commande de liaison montante pour le MeNB et une station de base secondaire (SeNB); le MeNB reçoit les informations de commande de liaison montante conjointes envoyées par l'UE selon le premier message d'indication (102). Le mode de réalisation de la présente invention est appliqué au rapport d'informations d'état de canal (CSI) dans des liaisons doubles.
