摘要

RAT-dependent 是 5G 自带的不依赖卫星的定位技术。3GPP 给出了单站理想条件下的定位精度克拉默-拉奥下界（CRLB

Cramer-Rao lower bound）并给出了多站在不同网络配置下的仿真定位精度。基于实际组网条件提出了多站定位精度的分析框架和精度范围，并提出相应的提升方法，实验结果表明，RAT-dependent 定位精度与组网技术紧密相关，优化方案相对于非优化方案定位精度可提升20%～30%。

Abstract

RAT-dependent is a satellite independent positioning technology of 5G.3GPP gives the Cramer-Rao lower bound (CRLB) of the positioning accuracy under the ideal condition of a single station and the simulation positioning accuracy of multi-station under different network configurations.Based on the actual network conditions

the analysis framework

accuracy range of multi-station positioning accuracy and the corresponding improvement method were proposed.The experimental results show that the RAT-dependent positioning accuracy is closely related to network technologies

and the positioning accuracy of the optimized scheme can be improved by 20%～30% compared with the non-optimized scheme.
