FuTURE B3G TDD is designed to provide 100 Mbps peak data rate in both uplink and downlink. In this paper, the MIMO channel measurement campaign carried out in BUPT campus is briefly introduced. Based on the results from the field channel measurement, the radio transmission parameters of physical layer is optimized, and the downlink performance of FuTURE B3G TDD is evaluated in system level with soft...
FuTUKE B3G TDD is designed to provide 100 Mbps peak data rate in both uplink and downlink. In this paper, based on the results from the field channel measurement, the radio transmission parameters of physical layer is optimized, 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...
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...
In a MIMO OFDMA multiuser system, the multiuser diversity gain can be achieved both in spatial and frequency domain by joint spatial and frequency scheduling. Although the channel estimation error (CEE) may degrade such multiuser diversity gain, little work has been performed on it. In this paper, we investigate the effect of the CEE on MIMO OFDMA uplink based on multiuser singular value decomposition...
In multiuser OFDMA system, multiuser diversity gain can be achieved by channel aware subcarrier and power allocation, and most work in this field is focused on the none-real time service. For real time (RT) service, not only the data rate, but also the packet delay should be guaranteed. In this paper, the multiuser subcarrier allocation is investigated for real time service. By exploiting the queue...
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...
Since the channel reciprocity can be obtained in TD-SCDMA LTE system, the channel status information (CSI) can be exploited at the transmitter to implement multiuser spatial division multiplexing (SDM) and obtain both the spatial multiplexing gain and multiuser diversity gain efficiently. In this paper, zero forcing beamforming (ZFB) and multiuser per antenna rate control with antenna selection (MU-PARC-AS)...
CSI can be utilized at the transmitter to implement close loop multiuser MIMO and obtain both full spatial multiplexing and multiuser diversity gain in uplink. In this paper, multiuser per antenna rate control (MU-PARQ) and multiuser singular value decomposition (MU-SVD) for spatial division multiplexing (SDM) of MIMO OFDM are investigated and a novel joint spatial frequency proportional fairness...
