Abstract：This paper focuses on the rate allocation algorithms on the reverse link (RL) of CDMA2000 system. Two conventional algorithms, the SCHedule (SCH) algorithm and the Dedicated Rate-Controlled (DRC) algorithm are compared and analyzed. Based on their pros and cons, a modified version of DRC algorithm is proposed, which is called Multi-step-Up DRC (MUDRC). While holding the advantages of DRC，the proposed algorithm can combat for the inherent slow ramp-up nature of DRC and enable a mobile to increase its rate by multiple steps when needed. Simulation results show that the proposed algorithm can efficiently utilize the radio resources and improve the user’s performance of delay. In addition, the performance gain is achieved by using the same amount of signaling overhead as that of DRC, which is much less than that of SCH. The proposed scheme can be generalized to other similar communication systems.
