Abstract

Cette invention se rapporte à un appareil et à un procédé servant à commander les puissances de transmission du canal indicateur de qualité de canal retour (R-CQICH) et du canal d'accusé de réception retour (R-ACKCH) indépendamment. Le procédé faisant l'objet de cette invention consiste à recevoir un premier paramètre correspondant au canal R-CQICH et un second paramètre correspondant au canal R-ACKCH à partir d'une station de base via un message de service, puis à déterminer indépendamment les puissances de transmission du canal R-CQICH et du canal R-ACKCH en utilisant ces premier et second paramètres.
