ABSTRACT
In this paper, we propose two downlink power control schemes based on utility during soft handover in DS-CDMA systems. Based on two di®erent soft handover algorithms, we also design two power control schemes during soft handover. Our proposals introduce the utility and pricing functions into the downlink power control algorithms during soft handover. The goal is to achieve the maximum revenue for handover users. Simulation results show that the performance is better when only one base station with the best channel gain transmits the users' information.
