%X For the IEEE 802.16j network,this paper proposed a dynamic joint bandwidth resource scheduling strategy for the services in uplink.According to the tree-topology of IEEE 802.16j system,used a hierarchical distributed resource scheduling scheme between the base station(BS) and the relay station(RS),which enhanced the bandwidth utilization and provided various multimedia communications with QoS guarantee effectively.At the same time,this paper proposed different scheduling algorithm for different types of services to improve the fairness.Simulation results show that the proposed scheme is more flexible than strict priority scheduling.It can meet various QoS requirements of multimedia services well without sacrificing services’rate fairness,and get the preferable utilization of bandwidth in WiMAX system.
