CA 2369957

A method and apparatus for controlling transmit power levels of a plurality of different data streams (120, 120a, 122, 122a, 124, 124a) transmitted from at least one base station to a mobile station in a mobile radio communication system. The first and second data streams are trasmitted from the base station and received at the mobile station. A stream of power control commands is formed at the mobile station in accordance with either the first or second received data stream. A power control signal is formed at the mobile station from the first stream of power control commands and transmitted to the base station. A received stream of power control commands is formed from the received power control signal at the base station, and the transmit power levels of the first and second data streams from the base station are controlled in accordance with the received stream of power control commands.

L'invention concerne un procédé et un système de réglage des niveaux de puissance de transmission d'une pluralité de trains de données différents (120, 120a, 122, 122a, 124, 124a) transmis depuis au moins une station de base vers une station mobile dans un système de communication radio mobile. Le premier et le deuxième trains de données sont transmis depuis la station de base et reçus à la station mobile. Un train de commandes de réglage de puissance est formé au niveau de la station mobile conformément au premier ou au deuxième train de données reçu. Un signal de réglage de puissance est formé au niveau de la station mobile à partir du premier train de commandes de réglage de puissance et transmis à la station de base. Un train de commandes de réglage de puissance reçu est formé à partir du signal de réglage de puissance reçu au niveau de la station de base, et les niveaux de puissance de transmission du premier et du deuxième trains de données provenant de la station de base sont réglés conformément au train de commandes de réglage de puissance reçu.
