Transmission power management and control in third-generation W-CDMA-based cellular systems

The adoption of W-CDMA as an essential component of the air-interface of third generation cellular systems brings the need for new planning methodologies and software tools. In this perspective, this paper addresses planning problems that are important to the dimensioning of W-CDMA-based cellular networks. The problems aim at finding the optimal feasible allocation of transmission power to the sets of uplink and downlink connections that should be supported by the system, so as to cope with a corresponding traffic load scenario. In this paper we focus on the uplink problem. Specifically this problem is concisely defined, mathematically formulated and solved by means of a computationally efficient, novel algorithm. The solutions of the problem will be exploited by management and control schemes in order to improve the system performance.
