  • In this paper, a novel QoS-guarantee efficient scheduling and resource allocation algorithm for heterogeneous traffics in the downlink of MIMO-OFDMA system is proposed, which sufficiently exploits the space,time, frequency resource to provide QoS-guarantee. The algorithm takes into consideration not only the advanced physical techniques but also the service characteristics, QoS requirements and fairness for users observed in the medium access control (MAC) layer. Simulation results show it can significantly improve the system throughput performance while guaranteeing efficient transmission for heterogeneous traffics.
