In MIMO OFDMA system, multiuser diversity gain can be achieved both in spatial and frequency domain by channel aware scheduling. For real time (RT) service, the data rate and the packet delay should be guaranteed. But for none-real time (NRT) service, larger packet delay is acceptable and multiuser diversity gain can be exploited more to improve the system throughput. In this paper, by exploiting...
For multiuser MIMO system, zero forcing beamforming (ZFB) can be adopted to exploit the multiuser spatial multiplexing gain and diversity gain in downlink by spatial multiuser scheduling. On the other hand, multiuser joint subcarrier allocation can obtain multiuser diversity gain in frequency domain. In this paper, a novel joint spatial and frequency proportional fairness (SFPF) scheduler is proposed...
