摘要：

摘要：利用广泛部署的5G网络基础设施为智能终端提供通信定位一体化服务是5G标准演进的重要特性，尤其在卫星导航信号不可达的室内环境中，5G通导融合的高精度定位将赋能智慧制造等众多垂直行业应用。目前，5G定位在实际部署场景中稳定达到亚米级精度仍然存在技术挑战，且缺乏一致的测试平台和环境。以实现亚米级5G定位部署应用为目标，分析了当前5G定位技术亟待解决的关键技术挑战，介绍了面向典型应用场景的5G定位专用仿真平台，通过仿真平台对5G测向技术进行评估，结果表明5G上行测向技术具有高精度定位的潜力。最后对5G室内高精度定位技术的产业化前景进行了展望。

Abstract:

Providing integrated communication and positioning services for smart terminals using widely deployed 5G infrastructure has been a promising way during the 5G standard evolution.Especially in an indoor scenario where the global navigation satellite system fails, high-accuracy localization services can be provided based on the 5G infrastructure, and thus, 5G integrated communication and localization will enable much vertical industry applications.However, there still exist many technical challenges for providing sub-meter-level 5G localization in practical applications.In addition, there is no unified testbed or platform to support the development of 5G localization.Firstly, the challenges that 5G positioning methods face in achieving indoor sub-meter accuracy were analyzed.Then the design of 5G positioning simulator focusing on 5G classical scenarios was introduced.Numerical results show that the uplink-angle-of-arrival-based approach can achieve sub-meter localization accuracy.Finally, the industrialization prospects of 5G indoor high-accuracy positioning technology were proposed.

Key words: 5G localization, high-accuracy positioning, integrated communication and positioning, simulator
