摘要：

5G网络在多种场景下提供位置服务，并对定位性能提出严格的要求。首先，结合3GPP 5G高精度定位的标准制定过程，介绍了3GPP定位性能需求和5G定位各个标准版本的定位功能规划；其次，重点介绍了5G网络辅助北斗全球卫星导航定位关键技术和标准进展；然后，分析了基于5G侧行链路信号定位的网络架构、关键技术和标准进展；最后，对6G定位标准演进发展方向进行了展望。

关键词: 网络辅助北斗卫星导航, 侧行链路定位, 3GPP, 5G定位标准

Abstract:

Location service features are enabled in 5G to allow new and innovative location-based services to be developed for kinds of scenarios and the key performance requirements are identified by 3GPP.Firstly, the planning of location service feature in each standard release of 5G was introduced based on the standard process of 5G high-accuracy positioning in 3GPP.Secondly, 5G network-assisted BeiDou navigation satellite system was studied, including the positioning technologies and the standard progress of A-BDS in 3GPP.Thirdly, the network architecture, key technologies and the standards progress for sidelink positioning in 5G were introduced.Finally, the evolution of 6G positioning was analyzed.

Key words: A-BDS, sidelink positioning, 3GPP, 5G positioning standards
