An apparatus and method is provided for dynamic range power control of a wireless downlink communication signal (100), such that target signal quality adjustments are held temporarily (102) when it is apparent that transmit power control commands will not produce the desired response at the transmitting station. Comparisons of measured received signals to thresholds are performed to determine whether the transmitting station has either reached the maximum or minimum transmit power, in which case the target signal quality adjustment is controlled accordingly. When normal transmit power is detected (121), the target signal quality adjustments are allowed to resume as usual.
L'invention concerne un appareil et un procédé de réglage de la puissance de la gamme dynamique d'un signal de communication de liaison descendante sans fil (100), permettant de suspendre temporairement les réglages de qualité du signal cible (102) lorsque les commandes de réglage de la puissance de transmission ne génèrent pas la réponse désirée au niveau de la station de transmission. Des comparaisons sont effectuées entre les signaux mesurés et des seuils afin de déterminer si la station de transmission a atteint la puissance de transmission maximale ou minimale, auquel cas le réglage de la qualité du signal cible est effectué en conséquence. Lorsqu'une puissance de transmission normale est détectée (121), les réglages de la qualité du signal cible peuvent reprendre normalement.
