Abstract:
A method of controlling power levels of signals transmitted by base stations in a communication system having base stations and remote stations, comprising the steps of: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;determining whether the remote station is simultaneously receiving a first signal transmitted by a first base station and at least one second signal transmitted by at least one second base station that include substantially identical message information;transmitting to a controller from the first base station a first report of a power level of the first signal;transmitting to the controller from the at least one second base station at least one second report of a power level of the at least one second signal;comparing in the controller the first report and the at least one second report;transmitting from the controller to the first base station a first command for adjusting the power level of the first signal; andtransmitting from the controller to the at least one second base station at least one second command for adjusting the power level of the at least one second signal, wherein 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.
