  • To meet the requirements of services with various quality of service in future broadband wireless communication systems, a satisfaction based scheduling scheme with hybrid beamforming strategy in multi-antenna downlink system is presented in this paper. This scheduler schedules users with joint considerations of users QoS requirements and channel quality. The Random beamforming and the Zero-forcing beamforming transmission schemes are selected according to satisfaction criterion. Punishment mechanism is proposed here to avoid users occupying too much more resource than their requirements. Simulation results show that the proposed strategy can guarantee users QoS requirements and exploit radio resource utilization better than that of the existed scheduling methods.
