This document studies further enhancements to the 5G system for the support of cyber-physical control applications in vertical domains. This document collects new use cases and enhanced functionality for communication in automation in vertical domains in clause 5. Potential new 5G service requirements for Rel.17 are derived for each use case. Use cases and enhanced functionality are collected for the following topics:

• Industrial Ethernet integration, which includes time synchronization, different time domains, integration scenarios, and support for time-sensitive networking (TSN) in clause 5.2, clause 5.3, clause 5.4, and clause 5.15;
• Non-public networks, non-public networks as private slices, and further implications on security for non-public networks in clause 5.14;
• Network operation and Maintenance in 5G non-public networks for cyber-physical control applications in vertical domains; Enhanced QoS monitoring, communication service and networks diagnostics; Communication service interface between application and 5G systems, e.g. information to the network for setting up communication services for cyber-physical control applications and corresponding monitoring in clause 5.5, clause 5.6, clause 5.7, clause 5.13, clause 5.17, and clause 5.19;
• Network performance requirements for cyber-physical control applications in vertical domains in clause 5.8, clause 5.16, and clause 5.18;
• Positioning enhancements, including relative positioning information and vertical directions / dimension for Industrial IoT in clause 5.9 and clause 5.12;
• Device-to-device/ProSe communication for cyber-physical applications in vertical domains in clause 5.10, clause 5.11, and clause 5.13.

The potential new 5G service requirements are consolidated in clause 6. Additional information of specific concepts of communication in automation in vertical domains and of cyber-physical control applications is given in clause 4 and in several of the annexes. This information is given for clarification and in order to help in correlating the application behaviour and 5G service requirements to the 5G system.

The present document identifies further Stage 1 potential 5G service requirements for cyber-physical control applications in vertical domains. The present document provides specific use cases to provide clarity and to motivate the additional service requirements. Relative to the Rel-16 baseline, there are more specific requirements or additional requirements for closely-related additional functionality in order to improve the applicability of 5G systems to vertical domains. The aspects addressed are:

• Industrial Ethernet integration, which includes time synchronization, different time domains, integration scenarios, and support for time-sensitive networking (TSN);
• Non-public networks, non-public networks as private slices, and further implications on security for non-public networks;
• Network operation and Maintenance in 5G non-public networks for cyber-physical control applications in vertical domains; Enhanced QoS monitoring, communication service and networks diagnostics; Communication service interface between application and 5G systems, e.g. information to the network for setting up communication services for cyber-physical control applications and corresponding monitoring;
• Network performance requirements for cyber-physical control applications in vertical domains;
• Positioning with focus on the vertical dimension for Industrial IoT;
• Device-to-device/ProSe communication for cyber-physical applications in vertical domains.
