摘要
3GPP于2017年6月冻结了NB-IoT R14版本的核心规范,针对本次的技术演进,定位功能成为R14版本的新特性之一。基于OTDOA定位技术的理论和实践研究,通过OTDOA定位系统的搭建,利用终端测量的定位参考信号的时间差,最终获取采用OTDOA定位方式的测量结果并对定位精度进行分析,最后给出NB-IoT定位的应用参考建议。
In June 2017,3 GPP frozen the core specification for the NB-IoT R14 version. For this technology evolution,the positioning function has become one of the new features of the R14 version. Based on the theoretical and practical research of OTDOA positioning technology,through the construction of OTDOA positioning system and the measurement of time difference of positioning reference signal by terminal,the measurement results using OTDOA positioning method are finally obtained and the positioning accuracy is analyzed. Finally,it gives reference to the application of NB-IoT positioning.
