0f  Foreword  p. 6

The present document implements Option 2 for decimal and thousands separator characters: "The decimal sign shall be a full-stop (period). The thousands separator shall be a comma." (clause 6.6.7 of TR 21.801 - v16.2.0).

0i  Introduction  p. 6

The present document addresses a challenging class of vertical applications, namely cyber-physical control applications, which require very high levels of communication service availability, and some of them also require very low end-to-end latencies.
Real-time Ethernet is one of the established wireline communication technologies for cyber-physical control applications, and this specification identifies requirements that 5G systems must meet to support real-time Ethernet.
The present document provides new Stage 1 requirements based on the input from relevant stakeholders of the respective vertical domains.

1  Scope  p. 7

The present document provides Stage 1 normative service requirements for 5G systems, in particular service requirements for cyber-physical control applications in vertical domains and requirements for auxiliary applications. 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. Examples for auxiliary applications are distributed sensing and asset monitoring.
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, Smart Grid .
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 Ethernet services specific to industrial/high performance use cases. Related Ethernet functionalities include, for example, those in IEEE 802.1Qbv;
  • direct device connection and indirect network connection for cyber-physical applications.
