摘要
该文针对基站隐藏安装场景位置工勘不准确导致定位目标用户定位精度不高的问题,提出了一种反向定位基站的方法。该方法通过测试终端向基站发起多次5G(5th Generation)测量,获取测试终端与基站之间的5G测量值往返时延(RTT,Round-TripTime),最后构建观测方程并采用最小二乘法求解得到基站的坐标位置。试验结果表明,该方法能有效获得隐藏安装场景中基站的准确位置。
This paper proposes a reverse positioning method for base stations to address the issue of inaccurate positioning of target users due to inaccurate location surveys in hidden installation scenarios.This method sends multiple 5G measurements to pRRU through the testing terminal to obtain the 5G measurement value RTT between the testing terminal and pRRU.Finally,the observation equation is constructed and the coordinate position of pRRU is solved using the least squares method.The experimental results show that this method can effectively obtain the accurate position of base stations in hidden installation scenarios.
