Abstract

This paper proposes a transmission power control scheme to improve geographical fairness for packet transmission in the downlink common channels of CDMA cellular systems. The proposed downlink transmission power control is based on the signal-to-interference ratio predicted at mobile stations. Throughput performance and transmission delay are evaluated under perfect power control conditions. Simulation results show that the proposed scheme improves the downlink throughput and geographical fairness in packet reception across the whole cell area
