Abstract

L'invention concerne un équipement utilisateur, un dispositif de réseau et un procédé permettant d'activer un canal de commande de liaison montante physique. L'équipement utilisateur comprend : un module de détermination permettant de déterminer, selon un changement d'état d'une cellule secondaire (SCell) configurée avec un canal de commande de liaison montante physique (PUCCH) dans un groupe de cellules de canal de commande de liaison montante physique cible (PCG), un PUCCH cible à activer dans le PCG cible ; et un module d'activation permettant d'activer le PUCCH cible déterminé par le module de détermination. Selon un changement d'état d'une SCell configurée avec un PUCCH dans un PCG cible, un équipement utilisateur peut déterminer un PUCCH cible à activer dans le PCG cible et active le PUCCH cible. Par conséquent, lorsque la configuration d'un PUCCH est remplacée, les surdébits de signalisation peuvent être réduits et le retard peut être réduit.
