[ I claim:] [1.] A communication station for communicating with a second station in a cellular-communication network using spread spectrum modulation wherein the second station transmits power commands to the communication station based on a received power level from the communication station, the communication station comprising:a transmitter having an adjustable transmitter power level for transmitting spread-spectrum signals;means for sequentially receiving power commands from a second station with which communication is being conducted;means for comparing a sequence of at least two of the received power commands to determine if the received commands in the sequence match; andmeans for adjusting the transmitter power level at a same rate as the reception of the power commands by steps; wherein if the command sequence does match, a magnitude of subsequent steps in the transmitter power level are increased by a fixed percentage and if the command sequence does not match, the magnitude of subsequent steps in the transmitter power level are decreased by the fixed percentage.
