5G基站上行干扰分析工具设计与实现

Design and Implementation of Uplink Interference Analysis Tool for 5G Base Station

目前基站上行干扰分析缺乏有效工具,工作效率低下。为提高基站上行干扰分析效率,分析了多种上行干扰产生的原因及其时频域特征,总结出干扰识别的规则,并开发出一种干扰分析工具。该工具根据多天的小时级PRB干扰话统绘制时频域干扰波形图、分析并给出干扰类型;大大提高了干扰分析效率,尤其在分析大量小区干扰时效果更为突出。该工具已在各区域推广使用,得到了一致认可。

At present,there is a lack of effective tools for base station uplink interference analysis,the work efficiency is extremely low.In order to improve the efficiency of uplink interference analysis of base station,this paper analyzes the causes of various uplink interference and their time-frequency characteristics,summarizes the rules of interference identification,and develops an interference analysis tool.This tool draws the time-frequency interference waveform diagrams,analyzes and gives the interference types based on multi-day hourly PRB interference traffic measurement;it greatly improves the efficiency of interference analysis,especially in the analysis of a large number of cell interference.The tool has been used in various regions and has been unanimously recognized.
