Abstract:

A scheduling algorithm is proposed for cdma2000 forward packet scheduling. In the conventional proportional fairness algorithm, fairness objective is achieved through the fairness exponent . is difficult to be optimized for the optimal value depends on many practical factors. In the proposed algorithm, the fairness objective is achieved by monitoring the real-time fairness of the maximum carrier to interferencescheduler. Hence we may achieve the maximal throughput while keeping the fairness criterion not violated. Simulation results indicate that the proposed algorithm has a similar system throughput to the conventional proportional fairness algorithm with optimized fairness exponent .

Key words: proportional fairness, max carrier to interference scheduling algorithm, multiuser diversity
