Abstract:
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.
