Abstract
A method and apparatus for dynamically adjusting a power control loop that attempts to maintain either the transmit power of a signal sent from a base station to a mobile station or the signal to noise ratio of a signal sent from the mobile station to the base station above a minimum threshold. Location information that is representative of the distance and morphology between the mobile station and the base station is determined. The minimum threshold of the power control loop is then adjusted in accordance with the location information such that the minimum threshold varies as the distance and the morphology between the mobile station and the base station change. A transmitter sends the signal at a power level that is controlled by the power control loop with the adjusted minimum threshold.
