摘要

TD-LTE上行干扰水平是评估网络质量的重要指标

当网络受到上行干扰时

上行吞吐量、尤其是小区边缘用户的上行吞吐量将受到影响

干扰严重时甚至会影响用户的接入性能。本文对TD-LTE系统上行干扰问题进行研究

提出干扰频域、时域及地理分布特征三维联合分析方法

实现了TD-LTE系统上行干扰的全方位分析

可大大提高TD-LTE干扰优化与排查工作的效率及准确性。

Abstract

Uplink interference level is an important indicator of TD-LTE network quality

uplink throughput

especially uplink throughput of cell edge user will suffer from uplink interference

and user access performance will be affected when high-level interference occurs. This paper studies on uplink interference of TD-LTE systems

proposes a three-dimension interference analysis method in which timedomain

frequency-domain and geographical distribution aspects of uplink interference are researched. This method realizes comprehensive interference analysis

which can greatly improve the efficiency and accuracy of TD-LTE interference optimization.
