Abstract
After setting a base station to a transmit power level (12) which provides a signal at a subscriber unit having a target quality level, a fading characteristic of a communication channel between the subscriber unit and a base site is measured (13). The fading characteristic is then compared with a threshold value (14). The measuring (13) and comparing (14) are repeated until the fading characteristic crosses a threshold (15). Once the fading characteristic crosses the threshold for a receive Eb/No level that is representative of a e.g. static fading condition, the base transmit power that is transmitted to the subscriber is increased by a predetermined amount in anticipation of the need for an increased Eb/No for the case of a faded signal (61). The determination of the fading characteristic and threshold comparison may be performed at either the subscriber unit or the base station.
