Positioning

 

The motivation and logics of NR positioning does not have much difference with LTE. For UE side measurement, a new kind of reference signal is defined (in Release 16) as in LTE. For Network side measurement, SRS is used as positioning reference (SRS is getting multipurposed as NR evolves).  The types of measurement that can be done is summarized as below. Nothing specifically new from LTE. But we may guess that the accuracy and granularity of these measurement would be improved considering that cell radius gets smaller and beamforming can help with some of the measurement like AoA, AoD.
