Joint Power and Rate Assignment for Downlink Throughput Maximization in Multi-Cell CDMA

A.I. Endrayanto, A.F. Gabor, R.J. Boucherie

Abstract



This paper presents a full analytical characterization of the optimal joint downlink rate and power assignment for maximal total system throughput in a multi cell CDMA network. The paper has three main contributions. First, we provide an explicit and exact characterization of the structure of the optimal rate and power assignment: in a network with N base transmitter stations (BTSs) either all mobiles have maximum rate, or in k BTSs all mobiles have maximum rate and the other BTSs transmit at maximum power, or N-1 stations transmit at maximum power. Second, we give a characterization of the optimal rate assignment in each cell. Third, we give an exact algorithm for solving the rate and power assignment problem and a fast and accurate heuristic algorithm for power and rate assignment to achieve maximal downlink throughput in a multi cell CDMA system.

Keywords


optimization, joint power and rate assignment, multi cell CDMA, exact and heuristics algorithm.
