The present document captures the findings of the study item "Study on NR positioning support" . The purpose of the
present document is to support NR positioning in TSG RAN WG1, WG2 and WG3 to properly model and evaluate the
performance of NR positioning solutions in deployment scenarios representing relevant use cases, both regulatory and
Here is reproduced Clause 4:
The 3GPP NR radio-technology is uniquely positioned to provide added value in terms of enhanced location
capabilities. The operation in low and high frequency bands (i.e. below and above 6GHz) and utilization of massive
antenna arrays provides additional degrees of freedom to substantially improve the positioning accuracy. The possibility
to use wide signal bandwidth in low and especially in high bands brings new performance bounds for user location for
well-known positioning techniques based DL-TDOA and UL-TDOA, Cell-ID or E-Cell-ID etc., utilizing timing
measurements to locate UE. The recent advances in massive antenna systems (massive MIMO) can provide additional
degrees of freedom to enable more accurate user location by exploiting spatial and angular domains of propagation
channel in combination with time measurements.
A general description of location services and service requirements are given in TS 22.071
Rel-15 NR WI specified Cell-ID, inter-RAT and RAT-independent positioning methods by reusing LPP, but NR
standalone based RAT-dependent positioning was excluded.
According to , the 5G system shall support the use of 3GPP and non-3GPP technologies to achieve higher accuracy
positioning. The corresponding positioning information shall be acquired in a timely fashion, be reliable, and be
available (e.g., it is possible to determine the position). The 3GPP system also presents 5G communication for
automation in vertical domains . This is communication that is involved in the production of and working on work
pieces and goods, and/or the delivery of services in the physical world. Such communication often necessitates low
latency, high reliability, and high communication service availability.
The SA1 HYPOS study  focused on positioning use cases in indoor and outdoor environments. The technical report
 complements existing work on 5G use cases involving positioning needs in order to identify potential requirements
for 5G positioning services. The document further develops the identified use cases by providing some considerations
on the suitability of positioning technologies to these use cases.
The following requirements were captured in . NR should enable, and improve if suitable, state-of-art positioning
techniques, such as RAN-embedded (Cell-ID, E-Cell ID, DL-TDOA, UL-TDOA, etc.) and RAN-external (GNSS,
Bluetooth, WLAN, Terrestrial Beacon Systems (TBS), sensors, etc.). NR positioning shall exploit high bandwidth,
massive antenna systems, network architecture/ functionalities (e.g. heterogeneous networks, broadcast, MBMS) and
deployment of massive number of devices. NR positioning shall support indoors and outdoors use cases.
NR shall support regulatory positioning requirements.
NR design targets for commercial positioning use cases include:
Support for range of accuracy levels, latency levels and device categories
Support accuracy and latency as defined in TR 22.862 for some use cases
Reduced network complexity
Reduced device cost
Reduced device power consumption
Efficient signalling over the air interface and in the network
Support for hybrid positioning methods
Scalability (support for large number of devices)
Support UE speed as defined in
