This paper investigates the power control mechanism in the context of third generation multimedia multirate wideband CDMA (WCDMA) mobile communications. We first present the system model and get the sufficient condition for the existence of feasible power assignment. Under this constraint, we reformulate the power control problem as a non-cooperative game in allocating the normalized QoS products, and propose a new call admission control (CAC) algorithm based on uniform-price auction (UPA) to control the power. Properties of UPA Nash equilibrium, especially its efficiency, are also discussed in wireless system environment. The results of comparison show that our scheme charging users on the QoS products has the enormous advantage over other pricing schemes charging users directly on the transmit powers. Numerical results which demonstrate the viability of the proposed algorithm are presented.
