1 Scope p. 8

This technical report relates to a study on positioning use cases for both outdoor and indoor environments. It analyses positioning use cases and complements existing work on 5G use cases involving positioning needs in order to identify potential requirements for 5G positioning services.

This document also identifies new use cases, their scope and environment of use along with the related KPIs. For use cases already addressed (fully or partially) in other 3GPP studies, it consolidates and validates the KPI and assumptions.

The document further develops the identified use cases by providing some considerations on the suitability of positioning technologies to these use cases. These considerations support the identification of potential requirements that can be achieved with 3GPP positioning technologies or with a combination of 3GPP and non-3GPP positioning technologies. The use cases and performance targets are independent of specific solutions even though, in order to support these considerations, the report provides some illustrative allocation between existing positioning technologies and 3GPP new positioning technologies (e.g. NR-based).

4 Overview p. 9

Clause 5 describes the positioning use cases, categorized by verticals, as follows:

Regulatory (e.g. emergency call, LI)
Mission Critical
Location-Based Services (e.g. LCS, gaming, social networking, position-enabled advertisement)
Industry and eHealth (e.g. automation, asset management and tracking, device telemetry - metering, patient monitoring)
Road (e.g. vehicle environment, road-user charging)
Railway
Maritime
Aerials (e.g. UAV/UAS)
Others

A synthesis of all the use cases requirements is provided in Clause 6 summarising targets for positioning services along with a grouping of some use cases, when this grouping is possible and relevant.

Clause 7 develops some considerations on the suitability of positioning technologies for the identified use cases, considering both 3GPP and non-3GPP positioning technologies. The related mapping builds on a background material to reveal the use cases that can be covered by existing technologies (standalone or combined) and the use cases for which 3GPP new positioning technologies (e.g. NR-enabled) are needed to cope with the shortcomings of existing technologies.

Clause 8 identifies initial potential requirements for 5G positioning services based on the considerations developed in Clause 7.
