The invention controls transmission power levels in a spread spectrum time division duplex communication station. A first communication station transmits a communication to a second communication station. The second station receives the communication and measures its received power level. Based on, in part, the received communication's power level and the communication's transmission power level, a path loss estimate is determined. A quality of the path loss estimate is also determined. The transmission power level for a communication from the second station to the first station is based on, in part, weighting the path loss estimate in response to the estimate's quality.
Méthode de régulation des niveaux de puissance de transmission dans une station de communication à duplexage temporel et à spectre étalé. Une première station de communication transmet une communication à une seconde station de communication. La seconde station reçoit la communication et en mesure le niveau de puissance. Une estimation de l'affaiblissement de propagation est calculée en fonction, notamment, du niveau de puissance de la communication reçue et du niveau de puissance de transmission de la communication. La qualité de l'estimation de l'affaiblissement de propagation est aussi évaluée. Le niveau de puissance de transmission d'une communication provenant de la seconde station et reçue par la première station repose en partie sur la pondération de l'estimation de l'affaiblissement de propagation en fonction de la qualité de l'estimation.
