Abstract
The optimal power allocation process of the present invention allocates power between two base stations, serving a given mobile radiotelephone, during soft hand-off. A minimum total transmit power is chosen initially. The minimum total transmit power level, the path losses for each base station, the maximum transmit power for each base station, and the minimum allowed received power are all used to generate a range of values for a transmit power level multiplier, .alpha.. The multiplier is used to allocate the total transmit power among the base stations. This process is performed until the probability of bit error is less than a maximum threshold.
