Abstract

Radio resource control is one of the key technologies for providing quality-of-service (QoS) in wireless communication systems, where power and data rate are schedulable resources. In this paper, we propose a utility-based resource control scheme for multimedia traffic in the downlink of DS-CDMA systems. The goal is to achieve the social optimal resource utilization. Fairness is guaranteed by allocating each user with a minimal transmission data rate. Simulation results show that the proposed resource control scheme is flexible and efficient for the downlink of multimedia DS-CDMA systems.
