摘要
3GPP制定的5G标准Release 15（Rel-15）版本仅支持紧急业务的位置服务需求，在Rel-16完成了5G位置服务网络架构、网元功能、端到端流程设计、定位参考信号、测量量、测量流程等的标准化后，成为了支持商业场景位置服务的完整版本。Rel-17则进一步缩短了定位服务时延、提升了定位精度到米级。3GPP在2022年开始Rel-18位置服务和定位研究项目，主要包含进一步提升定位性能指标（如更低时延、更高精度和更低能耗），以及进一步扩展定位功能（如支持 Sidelink 定位、用户面定位和卫星接入场景的终端位置验证等）。在介绍Rel-15/Rel-16/Rel-17位置服务研究进展的基础上，提出、分析了实现Rel-18定位的部分潜在关键技术，指出了6G网络的定位需求是更高的精度、支持更高速度场景的定位、支持更多的垂直行业和场景，人工智能、太赫兹通信将成为实现6G更高精度定位的潜在关键技术。
Abstract
The Release15 (Rel-15) of the 5G standard developed by 3GPP only supports the location service requirements of emergency services.The standardization of 5G location service network architecture
network element functions
end-to-end process design
positioning reference signals
measurement quantities
measurement processes
etc
has been completed in Rel-16
which is the complete version of location services that supporting business scenarios.In Rel-17
further reduction of the location service delay and improving the positioning accuracy are achieved.The 3GPP will start Rel-18 location service and positioning study in 2022
which mainly includes further improving positioning performance index
such as lower delay
and lower power and higher accuracy positioning
and further expanding positioning functions
such as supporting sidelink positioning
user plane positioning and UE (user equipment) location verification optimization of satellite access scenarios.Based on the introduction of the status of Rel-15/Rel-16/Rel-17 location services
some potential key technologies for realizing Rel-18 location services were put forward and analyzed.Then
the summary that the positioning requirements of 6G network are higher accuracy support the positioning of higher speed scenarios and support more vertical industries and scenarios was pointed out.Artificial intelligence and terahertz communication will become potential key technologies to realize 6G higher accuracy location services.
