摘要

随着定位技术的快速发展，面向5G-Advanced的高精度定位技术正受到越来越多的关注。首先，介绍了第三代合作伙伴计划（3rd Generation Partnership Project，3GPP）Rel-16和Rel-17的5G定位标准现状和Rel-18的5G-Advanced定位技术增强方向。其次，重点研究了5G正交频分复用（orthogonal frequency division multiplexing，OFDM）信号模型和载波相位定位技术需要解决的 3 个关键算法：基于锁相环的载波相位测量算法、基于参考终端的双差分算法和基于拓展卡尔曼滤波的用户设备（user equipment，UE）位置解算算法。最后，分析了低功耗高精度定位技术方案和基于定位参考设备的定位精度增强技术方案。

Abstract

With the rapid development of positioning technology

high-accuracy positioning technology for 5G-Advanced is receiving more and more attention.Firstly

the current situation of 5G positioning standards based on the 3rd Generation Partnership Project (3GPP) Release 16/ Release17 and the enhancement directions of the 5G-Advanced positioning technology based on 3GPP Release 18 were introduced.Secondly

the 5G orthogonal frequency division multiplexing (OFDM) signal model and three key algorithms for carrier phase positioning technology were mainly studied

including: carrier phase measurement algorithm based on phase locked loop

double-difference algorithm based on reference user equipment (UE)

and UE position calculation algorithm based on extended Kalman filter.Finally

the low-power high-accuracy positioning technology and the positioning accuracy enhancement technology based on positioning reference unit were analyzed.
