scope:

The present document provides Stage 1 normative service requirements for 5G systems, in particular service requirements for cyber-physical control applications in vertical domains. In the context of the present document, cyber-physical systems are to be understood as systems that include engineered, interacting networks of physical and computational components; control applications are to be understood as applications that control physical processes.

Communication services supporting cyber-physical control applications need to be ultra-reliable and, in some cases, the end-to-end latency must be very low. Communication for cyber-physical control applications supports operation in various vertical domains, for instance industrial automation and energy automation.

The aspects addressed in the present document include:

- end-to-end service performance requirements and network performance requirements related to these end-to-end service performance requirements;

- support for LAN-type services specific to industrial/high performance use cases. Related Ethernet functionalities include, for example, those in IEEE 802.1Qbv.
