Abstract This paper proposes an improved reverse link common rate control algorithm in CDMA system from practical utilization aspect. In this scheme, packet data service mobile controls its data rate to rise or decrease according to the change of Outer-Loop Power Control (OLPC) set point and Reverse Activity (RA) bit in a probabilistic manner. Analysis of probabilities is also presented in this paper and a sub-optimal and less complex solution is constructed. It is proved with system level simulation results that the improved scheme can enlarge system throughput and enhance resource utilization while maintaining Quality of Service (QoS) compared to existing algorithm only based on reverse active bit.
