Abstract

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

CLC Number:
