    Abstract: The present invention discloses 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; and means for adjusting the transmitter power level at a same rate as the reception of the power commands; wherein if the command sequence matches the transmitter power level is adjusted by a different amount than if the command sequence does not match. A method for adjusting a transmitter power level is also disclosed.
