摘要
本文对TD-LTE上行系统,从接收天线类型,上下行时隙配置,小区规模,系统带宽,载波频率这些不同的维度进行了广泛而详细的评估。同时在TD-LTE上行系统中对HPSS技术进行了评估。评估采用了符合3GPPE-UTRANLTE规范的系统级仿真平台。TD-LTE系统在1x8s天线配置下,性能明显优于FDD1x2系统。TD-LTE系统小区边缘用户对小区半径更为敏感。HPSS技术更适用于大半径小区,可使平均吞吐提高40%,边缘吞吐提高62%。
In this paper, profound and detailed evaluations in the TD-LTE Uplink System have been done under different assumptions such as receive antennas, UL/DL time slots, scale of cells, system bandwidth and frequency carrier. HPSS has also been researched in this system which is developed by the standard of 3GPP E-UTRAN LTE. Under the configuration of 1×8s receive antenna, TD-LTE system＇s performance is significantly better than FDD-LTE 1×2 and cell edge UE of TD-LTE is sensitive to the size of cell. HPSS have the highest gains which are 40% of average and about 62% of cell edge throughput in cell with large scope.
