1. A method for operating a mobile station, comprising steps of:

  • establishing a wireless data communication from a transmitter of the mobile station to a receiver of the base station at a predetermined data rate simultaneously through a fundamental data channel and at least one supplemental data channel;

    receiving a command from the base station to increase the transmission power of the mobile station transmitter;

    determining in the mobile station if the increased transmission power will exceed a transmission power threshold value;

    if so, reducing the data rate by disabling data transmission through the at least one supplemental data channel;

    increasing the transmission power;

    receiving a command from the base station to decrease the transmission power of the mobile station;

    determining in the mobile station if the decreased transmission power, assuming that a disabled supplemental data channel were once more enabled, will be less than the transmission power threshold value;

    if so, increasing the data rate by enabling data transmission through at least one previously disabled supplemental data channel; and

    decreasing the transmission power.
