This section lists the requirements applicable to the 5G system for supporting cyber-physical applications using Ethernet. For requirements pertaining to common, fundamental Ethernet transport requirements, and any requirements necessary to support the 5G LAN-type service, see Clause 6.24 in TS 22.261.

For infrastructure dedicated to high performance Ethernet applications, the 3GPP system shall support clock synchronisation defined by IEEE 802.1AS across 5G-based Ethernet links with PDU-session type Ethernet. For infrastructure dedicated to high performance Ethernet applications, the 3GPP system shall support clock synchronisation defined by IEEE 802.1AS across 5G-based Ethernet links and other ethernet transports such as wired and optical (EPON.) For infrastructure dedicated to high performance Ethernet applications, the accuracy of clock synchronisation should be better than 1μs. For infrastructure dedicated to high performance Ethernet applications, the 3GPP system shall support enhancements for time-sensitive networking as defined by IEEE 802.1Q, e.g. time-aware scheduling with absolute cyclic time boundaries defined by IEEE 802.1Qbv [19], for 5G-based Ethernet links with PDU sessions type Ethernet. For infrastructure dedicated to high performance Ethernet applications, absolute cyclic time boundaries shall be configurable for flows in DL direction and UL direction. For infrastructure dedicated to high performance Ethernet applications, the 3GPP system shall support coexistence of hard-RT traffic following a time-aware schedule and lower priority traffic. The lower priority traffic cannot have a performance degrading impact on the hard-RT traffic. The Ethernet transport service shall support routing based on information extracted from the Ethernet header information created based on IEEE 802.1Qbv.

This section lists the requirements applicable to the 5G system for supporting cyber-physical control applications using wireless indirect network connection.

The robustness of the infrastructure for electrical power distribution may depend upon the possibility to operate telecommunication networks even during an energy system incident, in which electricity cannot be delivered to some network operator facilities. Through coordination between the network operator and the energy system operator, increases in the ability to recover the energy system operation can be achieved.

Subject to regulatory requirements and operator policy, the 5G system shall support a mechanism by which an MNO can identify the ability of the MNO's infrastructure to continue operation despite a lack of electrical supply service, specifying which physical regions would be affected in terms of physical topology and the remaining time in which operation is possible. Subject to regulatory requirements, the 5G system shall support a mechanism by which a third party can, in the event of an energy distribution system service interruption, communicate the energy distribution system recovery status in terms of location and time table to the MNO.
