摘　　要：天线方位角是宏站小区的重要工程参数。受规划、安装、维护及自然等多重因素影响,部分宏站小区方位角不准确,影响无线网络优化正常开展。提出了一种基于MDT技术的提升宏站小区方位角准确性的新方法。首先以基站经纬度为原点构建平面直角坐标系计算宏站小区MDT采样点方位角,其次将采样点按其方位角撒到对应采样点分布区间,然后找到采样点数最大的分布区间即为该小区MDT采样点理想分布区间,理想分布区间的中间值即为该小区的理想方位角。现场验证表明,如果理想方位角与宏站小区天线方位角偏差≤20°时认为理想方位角准确,则本方法计算出来的理想方位角准确率为89.03%。Antenna azimuth is a crucial engineering parameter for macrocell sectors.Affected by factors such as planning,installation,maintenance,and natural influences,the azimuth of some macrocell sectors may be inaccurate,impacting the normal progression of wireless network optimization.This paper introduces a novel method leveraging MDT technology to enhance macrocell azimuth accuracy.Initially,a Cartesian coordinate system is established using the base station’s latitude and longitude as the origin to calculate the azimuth of MDT sampling points for macrocell sectors.Subsequently,these sampling points are allocated to corresponding angular intervals based on their azimuths.The interval with the highest number of sampling points is identified as the ideal distribution range for the sector,with its midpoint representing the sector’s ideal azimuth.Field validation demonstrates that if the deviation between the ideal azimuth and the macrocell sector’s antenna azimuth is≤20°,the method achieves an ideal azimuth accuracy rate of 89.03%.
