Abstract :
In this paper, we propose a downlink packet scheduling algorithm in OFDMA systems for the mixed services, such as real-time (RT) and non-real-time (NRT) services. The proposed scheduling algorithm is based on the channel state information and utility function of queuing delay. Simulation results show that this algorithm can not only guarantee the fairness and delay requirements of users with different types of services but also obtain good system throughput.
