Power allocation in the context of dimensioning the air‐interface of third generation W‐CDMA‐based cellular systems

Abstract

SUMMARYThe adoption of W-CDMA as an essential component of the air-interface of third-generation cellular systems brings to the foreground 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-CDMAbased 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. The problems are concisely defined, mathematically formulated and solved by means of two computationally efficient, novel algorithms. The solutions of the problems may be seen as operating points at which the system performance should be driven. Finally, numerical results are presented and concluding remarks are drawn.

Evaluation of management functionality for the power control operation of WLAN systems

“…Cell 16, which is heavily shaded, presents particularly increased traffic. Its neighboring cells (10,11,15,17,22,23) are depicted with a lighter color and present intermediate traffic, while the remaining cells (region of the network) are marked with white color and face lower traffic.…”

“…The solution algorithm is influenced by the scheme analyzed in Refs. [15,18,19]. It is based on the Jacobi iterative method, a standard method of numerical analysis.…”
