Analysis of NR Positioning Evolution: From Scenarios to Techniques
The development of 5G generates the promotion of mMTC scenarios such as HOT and V2X, which highlights the requirements of positioning enhancement. In this paper, NR positioning evolution is analyzed from 3GPP standard perspective. we provide the analysis of basic positioning method introduced in Rel-16 and summary the enhancement for improving the accuracy and reducing the latency on NR positioning in Rel-17. Moreover, in order to meet the services' requirement defined in 3GPP SA WG, we propose the potential techniques that can enhance the NR positioning for the newly introduced scenarios in Rel-18.
