6.27  Positioning services |R16|p. 48

6.27.1  Descriptionp. 48

5G positioning services aims to support verticals and applications with positioning accuracies better than 10 meters, thus more accurate than the ones of TS 22.071 for LCS. High accuracy positioning is characterized by ambitious system requirements for positioning accuracy in many verticals and applications, including regulatory needs.
In Location-Based-Services and eHealth, higher accuracy is instrumental to new services and applications, both outdoor and indoor.
For example, on the factory floor, it is important to locate assets and moving objects such as forklifts, or parts to be assembled. Similar needs exist in transportation and logistics, for example rail, road and use of UAVs. In some road user cases, UE's supporting V2X application(s) are also applicable to such needs. In cases such as guided vehicles (e.g. industry, UAVs) and positioning of objects involved in safety-related functions, availability needs to be very high.
Mission Critical Organizations require mission critical services to have accurate positioning such that first responders can be located at all times during normal and critical operations, indoors as well as outdoors. The level of positioning accuracy (and other KPIs) required is much more stringent than that required by local and regional regulatory requirements for commercial 5G users.

The 5G system shall provide different 5G positioning services, supported by different single and hybrid positioning methods to supply absolute and relative positioning.
The 5G system shall enable an MCX UE to use the 5G positioning services to determine its position with the associated uncertainty/confidence of the position, on request, triggered by an event or periodically.
The 5G System shall be able to provide the 5G positioning services in case of roaming.
The 5G system shall support mechanisms to determine the UE's position-related data for period when the UE is outside the coverage of 3GPP RAT-dependent positioning technologies but within the 5G positioning service area (e.g. within the coverage of satellite access).
The 5G system shall be able to make the position-related data available to an application or to an application server existing within the 5G network, external to the 5G network, or in the User Equipment.
The 5G system shall be able to manage and log position-related data in compliance with applicable traceability, authentication and security regulatory requirements.
The 5G network shall be able to request the UE to provide its position-related-data on request-together with the accuracy of its position-triggered by an event or periodically and to request the UE to stop providing its position-related data periodically.
The 5G system shall support mechanisms to configure dynamically the update rate of the position-related data to fulfil different performances (e.g. power consumption, position service latency) or different location modes.
The 5G system shall allow the UE to trigger a different update rate of the position-related data based on whether the UE is moving or not.
The 5G system shall be able to determine the position-related data of the 5G positioning services with any update rate ranging from one set of position-related data every 0,1 s to one set of position-related data every month.
The 5G System shall be able to negotiate the positioning methods according to the operator's policy or the application's requirements or the user's preferences and shall support mechanisms to allow the network or the UE to trigger this negotiation.
The 5G system shall supply a method for the operator to configure and manage different positioning services for different users.
The 5G system shall be able to determine the reliability, and the uncertainty or confidence level, of the position-related data.

6.28  Cyber-physical control applications in vertical domains |R16|p. 49

6.28.1  Descriptionp. 49

The 5G system is expected to meet the service requirements for cyber-physical control applications in vertical domains.
A vertical domain is a particular industry or group of enterprises in which similar products or services are developed, produced, and provided. Automation refers to the control of processes, devices, or systems in vertical domains by automatic means. The main control functions of automated control systems include taking measurements, comparing results, computing any detected or anticipated errors, and correcting the process to avoid future errors. These functions are performed by sensors, transmitters, controllers, and actuators.
Cyber-physical systems are to be understood as systems that include engineered, interacting networks of physical and computational components. Cyber-physical control applications are to be understood as applications that control physical processes. Cyber-physical control applications in automation follow certain activity patterns, which are open-loop control, closed-loop control, sequence control, and batch control.
Communication services supporting cyber-physical control applications need to be ultra-reliable, dependable with a high communication service availability, and often require low or (in some cases) very low end-to-end latency.
Communication in automation in vertical domains follows certain communication patterns. The most well-known is periodic deterministic communication, others are a-periodic deterministic communication and Smart Grid.
Smart Grid is a term that refers to enhanced cyber-physical control of electrical grids and to related application. Smart Grid operation can cover power generation, transmission, distribution, and consumption, which can require high communication service availability and communication service reliability, and in some cases a low end-to-end latency with more accurate clock synchronization. 5G system functionalities can be used for Smart Grid control, monitoring, availability assurance, service security, isolation and etc.Communication for cyber-physical control applications supports operation in various vertical domains, for instance industrial automation and energy automation.
For more information about cyber-physical control applications in specific vertical domains, see clauses D.1 to D.4.
