Specifically, we understand SA WG2's question to SA WG4 to be whether it is expected, in the transport of professional audio and video application content, for 5GS to perform network-based de-jittering of media streams (e.g., via hold\/forward buffering) such that AV samples do not arrive at the recipient media playout device earlier than the expected arrival time. SA WG4 subsequently discussed this matter, and based on also checking related reference information in TS 22.263, TS 23.700-20, IEEE 802.1Qbv and SMPTE ST 2110-10, and conclude that typically professional audio and video applications already contain de-jitter buffers to accommodate time variability of inter-packet arrivals at the receiving device. Therefore, in response to the SA WG2 question, SA WG4 is of the opinion that current professional audio and video applications do not expect nor require the 5GS to de-jitter the traffic (e.g., by use of hold\/forward buffering). Actions: SA WG4 kindly asks SA WG2 to take into account the above response from SA WG4, and provide us any related feedback or questions.","secretary_remarks":"Revision of postponed S2-2103738 from S2-145E.

Re interoperability between 1588 editions: The IEEE 1588 working group created IEEE Std 1588-2019 such as to be backward compatible with IEEE 1588-2008. By that we mean that if you do not use the new optional features in the 2019 edition, then the old ones work the same as in 2008. However, care should be taken to make sure that the same optional features are implemented to allow equipment to interoperate. See IEEE 1588-2019 clause 19 on compatibility between the 2019 and 2008 editions. 2. Re interoperability issues with non-synchronizing BC: The behavior you described is allowed in IEEE 1588-2019, if the other requirements for Boundary Clocks are met. There could be potential interoperability issues between the SMPTE ST2059-2 profile devices and the Boundary Clock in 5GS as described in the Liaison statement. We defer to SMPTE to identify interoperability issues with their profile. 3. Re SMPTE profile update: We defer to SMPTE for any information on updates to their PTP profile.

{"name":"S2-2105566","title":"Exposure of Time synchronization as a service - description","source":"Nokia, Nokia Shangai Bell, Samsung, Deutsche Telekom, Huawei, HiSilicon, ETRI","contact":"Devaki Chandramouli","contact-id":68275,"tdoctype":"CR","for":"Approval","abstract":"Summary of change: Following is proposed: It is proposed to define standardized time sync accuracy levels. AF provides Time synchronization accuracy requirement TSC TSF derives 5GS Time sync accuracy level from standardized list of Time Sync accuracy levels, considering also UPF induced time sync error. The derived accuracy level is then signaled towards the NG-RAN. When evaluating time synchronization accuracy within 5GS, the considered RAN time synchronization scenarios may involve one (e.g. control-to-control GM behind CN and smart grid) or two (e.g. control-to-control GM behind UE) Uu interface(s). However, the serving gNB(s) cannot determine which scenario applies. The gNB is responsible of providing 5G clock time information to the UE via SIB9 and\/or RRC but it is unaware of the time synchronization network topology that may be configured on top of the 5G clock synchronization process (e.g. NW-TT involvement for (g)PTP). Without the knowledge of the time synchronization scenario, the Uu synchronicity budget bounds (i.e. bounds of the 5GS time synchronization error between the UE and the gNB-DU) per UE cannot be derived to assist time information distribution configuration (referenceTimeInfo) or time synchronization enhancements such as PDC decision. RAN WG1 is studying the PDC method to address the time synchronization accuracy requirements of the 3 RAN scenarios. Two main alternatives are under consideration (as shown in Figure 1): TA-based PDC and RTT-based PDC (relying on Rx-Tx measurement currently known from the Multi-RTT procedure used for positioning purposes). The minimum signaling required for the RTT-based PD estimation method is an DL and UL Reference Signal (RS) and an Rx-Tx measurement report. Both nodes conduct an Rx-Tx measurement, but only one reports the Rx-Tx measurement to the node combining the two measurements to obtain an RTT estimation. On the other hand, support of legacy TA-based (Release-16) for PDC estimation, as it is sufficiently accurate, adds no additional overhead and requires no enhancements to handle at least the smart grid scenario (other additional enhancements considered for TA can extend the support to other RAN scenarios) (see discussion in R1-2102821): \/ Figure 1: PDC methods under consideration in RAN. For R17, it is assumed RAN WG2 will include in the specification an optional UE capability associated with higher accuracy PD estimation to the standard to trigger the PDC configuration at gNB\/UE when needed. Another aspect for time synchronization service is how often timing information needs to be provided to maintain accuracy at the UE, including during mobility events. The RAN needs to make assumptions regarding the filtering\/holdover capabilities which may reside in the UE, DS-TT, or in the application (external to 3GPP). It is proposed to add a 'Note' that a device can be assumed to have holdover capability to maintain its synchronized time with an accuracy corresponding to the UE modulated carrier frequency error requirement. This corresponds to a drift of maximal 16ns during a typical SIB9 rate of 160ms (based on TS 38.101-1). For mobility events, it is agreed in RAN WG2 that ignore time-sync drift during handovers can be ignored (RAN WG2 #113e Chairman's Notes), as attached: Assumptions: - There is no UE clock drift issue to be addressed - The source and target gNB are tightly synchronized to the same master clock within the budget and there is no need to optimize anything for HO. Agreements - gPTP message interruption during mobility is not considered in the Rel-17 IIoT WI (i.e. no further specification impact are considered)","secretary_remarks":"r10 agreed.
