A forward link power control mechanism in a remote station (6) measures reverse link power control bits which are transmitted by one or more base stations (4a, 4b, 4n) on a forward traffic channel (10a). At the remote station (6) the reverse link power control bits from multiple base stations (4a, 4b, 4n) or multiple signal paths are measured, combined, and filtered to yield an improved measurement of the forward link signal quality. The reverse link (12a, 12b) power control bits which are deemed unreliable are omitted from use in the power control loop. The remote station (6) generates a set of forward link power control bits in accordance with the measurements and transmits these bits to all base stations (4a, 4b, 4n) in communication with the remote station (6). Each base station (4a, 4b, 4n) adjusts its gain of the forward traffic channel (10a) in accordance to its measurement of the forward link power control bit. The gains of the forward traffic channels (10a) of the base stations (4a, 4b, 4n) are corrected periodically so that erroneous reception of the forward link power control bits by the base stations do not accumulate.

L'invention concerne un dispositif de commande de puissance de liaison aval dans une station distante (6), qui contrôle les bits de commande de puissance de liaison retour transmis par une ou plusieurs stations de base (4a, 4b, 4n) sur un canal de trafic aller (10a). Au niveau de la station distante (6), les bits de commande de puissance de liaison retour émis par plusieurs stations de base (4a, 4b, 4n) ou les trajets de signaux multiples sont déterminés, combinés et filtrés, ce afin de produire une mesure améliorée de la qualité des signaux sur la liaison aller. Les bits de commande de puissance de liaison retour (12a, 12b) jugés non fiables sont omis dans l'utilisation de la boucle de commande de puissance. La station distante (6) fournit une série de bits de commande de puissance de liaison aller sur la base des mesures effectuées, et transmet ces bits à toutes les stations de base (4a, 4b, 4n) communiquant avec la station distante (6). Chaque station de base (4a, 4b, 4n) ajuste son gain pour le canal de trafic aller (10a) en fonction de l'évaluation qu'elle fait des bits de commande de puissance sur liaison aller. Le gain des canaux de trafic aller (10a) des stations de base (4a, 4b, 4n) est ajusté régulièrement de sorte que la réception erronée des bits de commande de puissance sur liaison aller par les stations de base ne s'accumule pas.
