We present a novel scheme that maximizes the number of admissible mobiles while preserving quality of service and resources in wideband CDMA networks. We propose the integration of the genetic algorithm for mobiles equilibrium (GAME) with the standard closed loop power control (CLPC). This integration allows benefiting from the advantages of both techniques. In the proposed protocol, the base station recommends through GAME the optimum power and rate vector to each user. Meanwhile, a standard closed loop power control command is maintained to facilitate real time implementation. The goal here is to achieve an adequate balance between users. Therefore, each mobile can send its traffic with a suitable power to support it over the different path losses. In the mean time, its battery life is being preserved while limiting the interference seen by neighbors. Consequently, more mobiles can be handled. A significant enhancement in cell capacity, signal quality and power level has been noticed through several experiments on combined voice, data and video services.
