base station,
Ptk= g(rt,k)PO
where Po is the maximum transmission power. The optimum power functions are transmitted to the Mobile station which calculates the optimal power and starts transmitting at that value. Thus meeting the required QoS parameters.The method and algorithm for optimal power control is detailed in the IEEE paper 503476[[Media:IEEEYao.pdf|Optimal power control law for Multi-media - Multi-rate CDMA systems
