CA 2546389

A transmission power control method in a wireless communication system comprises the steps of receiving from a base station via an overhead message a first gain value (S23) associated with controlling transmission power for transmitting data acknowledge information (ACK, NAK) and a second gain value (S13) associated with controlling transmission power for transmitting channel quality information (CQI) wherein the transmission power of the reverse- acknowledgment channel (R-ACKCH) and the reverse-channel quality indicator channel (R-CQICH) are independently determined (S24, S14) using said first and second gain values.

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.
