The present invention employs a method and apparatus for providing improved power control when changing the rate at which data is sent in a communications system. When data arrives at the transmitter for transmission at a high rate, power control feedback is changed from a slow mode (with a low bandwidth feedback channel) to a fast mode (with a high bandwidth feedback channel). This control changes even before the data is transmitted at the high rate. Once the power level is accurately estimated for data transmission at the high rate, then data transmission begins at the high rate.

[ We claim:] [1.] In a communication system having at least one base station and at least one user station, transmitting signals over forward and reverse links, respectively, said forward and reverse links each containing a communication channel and a feedback channel and each channel having a separate channel bandwidth, a method for controlling transmission signal power in said communication system comprising the steps of:sending signals at a low rate from at least one of said user stations and said base station;receiving for transmission data signals at a data rate, said data rate being faster than said low rate;increasing said bandwidth of said feedback channel of said reverse link;receiving increased bandwidth power control signals over said feedback channel of said reverse link; andestimating said transmission signal power required to send data signals at a data rate based on said increased bandwidth power control signalschanging said transmission signal power to match said selected transmission signal power of said data rate;sending data signals at said data rate from at least one of said user stations and said base station.
