Abstract

This paper considers a static downlink power allocation algorithm for a multi-cell system in order to maximize the average system throughput. Based on observation that at least one base station (BS) has to transmit at the maximum power for optimal power allocation, and the optimal binary power allocation (OBPA) may still cause excessive interference, we propose a multi-stage greedy power allocation (MSGPA) which allows some of BSs to have several discrete transmit power levels by introducing multi-stage power adjustment. The simulation results show that the MSGPA outperforms the OBPA while significantly reducing complexity and transmit power as well.
