Abstract :
For the downlink of MIMO-OFDM system, a novel proportional fairness with joint space-time-frequency scheduling is proposed in this paper. On one hand, by space-time-frequency scheduling one can gain multiuser spatial multiplexing on the same subcarrier in one timeslot. On the other hand, with modified traditional proportional fairness, the system can provide QoS guarantee for various service types. The combination of space-time-frequency scheduling and novel proportional fairness makes the system perform well in respect of QoS provision without sacrificing much throughput.
