ABSTRACT:
A method and apparatus for controlling data transmissions from a first communications unit (202) to a second communications unit (210). Data transmissions received from the first communications unit (202) at the second communications unit (210) are processed to determine a power level of the data transmission. In response to a determination that the power level is not within a desired range or operating window (400), an adjustment value indicating the amount of change needed in the power level of the data transmission from the first communications unit (202) to fall within the desired range or operating window (400) is determined. This adjustment value is sent to the first communications unit (202). In response to receiving an adjustment value from the second communications unit (210), the first communications unit (202) adjusts the power level of its data transmissions. The first communications unit (202) and second communications unit (210) form a closed loop system providing for automatic gain control of the power level of data transmissions from the first communications unit (202).
