Downlink power control with limit to dynamic range using detection of downlink transmit power


Abstract
An apparatus and method is provided for dynamic range power control of a wireless downlink communication signal, such that target signal quality adjustments are held temporarily when it is apparent that transmit power control commands will not produce the desired response at the transmitting station. Comparisons of measured received signals to thresholds are performed to determine whether the transmitting station has either reached the maximum or minimum transmit power, in which case the target signal quality adjustment is controlled accordingly. When normal transmit power is detected, the target signal quality adjustments are allowed to resume as usual.
