Performance degradation of Cell Centre UEs (CCUs) and "Interference Flooding" phenomenon may happen in Single-Carrier Frequency Division Multiplexing Access (SC-FDMA) uplinks. To decrease the impact of Interference Flooding and improve the CCUs' throughputs, this paper proposes a UE-Interfering-Area (UIA) based Inter-Cell Interference Coordination (IOC) scheme. Using UIA scheme, the eNodeB...
As a key technology in future mobile communications system, OFDMA has efficient frequency utilization and strong robustness to frequency selective fading, however it's sensitive to synchronization errors. Although effects of synchronization errors on crossed timeslot's performance have been widely investigated in TDD/CDMA system, little work has done in TDD/OFDMA system. This paper analyzes the effects...
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...
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...
