Abstract
A method for controlling the power transmission levels in a spread spectrum or CDMA cellular system is disclosed, in which the decision to increase or decrease the transmission power level of a mobile station or base station, and the amount of any such increase or decrease made, is based on the weighted combination of a plurality of factors that indicate existing channel conditions. For example, the weight can be set according to the reliability of each channel condition factor involved.
