Abstract

The method involves transmitting power level control commands from a remote station to the base stations from which the remote station is receiving signals, to control the power levels of the signals transmitted by the base stations. A determination is made whether the remote station is simultaneously receiving a signal transmitted by a base station and a second signal transmitted by a second base station that include identical message information. A report of a power level of the first signal is transmitted to a controller from the base station. A second report of a power level of the second signal is transmitted to the controller from the second base station. A comparison is made in the controller the first report and the one second report. A command is transmitted from the controller to the first base station to adjust the power level of the first signal. The method transmits from the controller to the second base station a second command adjusting the power level of the second signal, the power level control commands are transmitted less frequently from the remote station to the base stations when the remote station receives signals from more than one base station than when the remote station receives signals from only one base station. The same power level control commands are transmitted several times from the remote station to the base stations when the remote station receives signals from more than one base station.
