5.3  Aperiodic deterministic communicationWord‑p. 19
Aperiodic deterministic communication is without a pre-set sending time, but still with stringent requirements on timeliness and availability of the communication service. A description of aperiodic deterministic communication can be found in Clauses 4.3 and 4.4. Additional information on the underlying use cases of the sets of requirements in Table 5.3-1 can be found in Annex A. Further information on characteristic parameters and influence quantities used in Table 5.3-1 can be found in Annex C.
The 5G system shall be able to provide aperiodic deterministic communication with the service performance requirements for individual logical communication links that realise the communication services reported in Table 5.3-1.

5.6  Clock synchronisation requirementsWord‑p. 23
5.6.0  Description
Clock synchronicity, or time synchronization precision, is defined between a sync master and a sync device. The requirement on the synchronicity budget for the 5G system is the time error contribution between ingress and egress of the 5G system on the path of clock synchronization messages.
5.6.1  Clock synchronisation service level requirements
The 5G system shall support a mechanism to process and transmit IEEE1588v2 / Precision Time Protocol messages to support 3rd-party applications which use this protocol.
The 5G system shall support a mechanism to synchronise the user-specific time clock of UEs with a global clock.
The 5G system shall support a mechanism to synchronize the user-specific time clock of UEs with a working clock.
The 5G system shall support two types of synchronization clocks, the global time domain and the working clock domains.
The 5G system shall support networks with up to 128 working clock domains (with different synchronization domain identifiers / domain numbers), including for UEs connected through the 5G network.
The 5G system shall be able to support up to four simultaneous synchronization domains on a UE.
The synchronicity budget for the 5G system within the global time domain shall not exceed 900 ns.
The synchronicity budget for the 5G system within a working clock domain shall not exceed 900 ns.
The 5G system shall provide a media dependent interface for one or multiple 802.1AS sync domains [22].
The 5G system shall provide an interface to the 5G sync domain which can be used by applications to derive their working clock domain or global time domain (Reference Clock Model).
The 5G system shall provide an interface at the UE to determine and to configure the precision and time scale of the working clock domain.
The 5G system shall be able to support arbitrary placement of sync master functionality and sync device functionality in integrated 5G / non-3GPP TSN networks.
The 5G system shall be able to support clock synchronization through the 5G network if the sync master and the sync devices are served by different UEs. (Flow of clock synchronization messages is in either direction, UL and DL.)
The 5G system shall provide a suitable means to support the management of the merging and separation of working clock domains, that is interoperable with the corresponding mechanisms of TSN and IEEE 802.1AS.

5.6A  Time-sensitive communication requirements |R17|
The 5G system shall support the fully distributed model for configuration of time-sensitive networking.
The 5G system shall support the fully distributed model for configuration of time-sensitive networking that is aligned with Multiple Stream Registration Protocol (MSRP, IEEE 802.1Q [19] clause 35.1), IEEE P802.1CS Link-local Registration Protocol (LRP) [24], and IEEE P802.1Qdd Resource Allocation Protocol (RAP) [25].
The 5G system shall support the user-network / network-network interface for the dynamic configuration of the fully distributed model for time-sensitive networking.

5.7  Positioning performance requirements
High accuracy positioning is becoming essential for Factories of the Future. The reason for this is that tracking of mobile devices as well as mobile assets is becoming increasingly important in improving processes and increasing flexibility in industrial environments.
The 5G system shall provide positioning information for a UE that is out of coverage of the network, with accuracy of < [1 m] relative to other UEs that are in proximity and in coverage of the network.
Table 5.7-1 below lists typical scenarios and the corresponding high positioning requirements for horizontal and vertical accuracy, availability, heading, latency, and UE speed.

5.8  Network operation requirements |R17|Word‑p. 25
For use by Industry 4.0, the 5G system needs to meet various operational options that are not typical in a traditional mobile operator setting. Additional system requirements that enable a 5G system to support those options are included in this clause.
5G system shall provide support for reliable communications when a UE serves as a TSN talker or listener so there is no single point of service failure.
