System Performance Evaluation on FuTURE B3G TDD System from Field Channel Measurement
FuTURE B3G TDD is designed to provide 100Mbps peak data rate in both uplink and downlink. In this paper, based on the results from the field channel measurement, the radio transmission prameters of physical layer is optimizaed, and the downlink performance of FuTURE B3G TDD is evaluated in system level. To provide a multi-cell coverage, a soft frequency reuse is adopt. Further, a joint spatial and freqency scheduling is proposed to explore the multiuser diversity gain at both spatial and frequency domain. As the channel reciprocity can be obtained in TDD system, the Channel Status Information (CSI) can be exploited at the transmitter to obtain the spatial-frequency multiuser diversity by joint spatial-frequency subcarrier and antenna assignment of MIMO OFDMA for the independent fading of different user in spatial and frequency domain. With the optimised radio transmission parameters, the peak data rate and system throughput can be improved 12.7％. The downlink system throughput in multi-cell scenario can achieve about 30Mbps with 4×2 MIMO in 10MHz bandwidth.
