Abstract

A method for initial downlink transmit power adjustment for non-real time services in a wireless communications network begins by estimating an initial downlink transmit power level for non-real-time services. The estimated power level is then compared with a threshold. A determination is made whether an increase in the estimated power level would affect neighboring cells. If an increase would not affect neighboring cells, then the initial downlink transmit power level is adjusted by a predetermined amount.
