RAN WG2 would like to provide the following feedback: The use of SNTP for time synchronization in MBS is outside RAN WG2 scope RAN WG2 confirms that the UTC time with 10 ms granularity in SIB9 (i.e. timeInfo IE including timeInfoUTC) can be used for time synchronization between gNB and UE. It is optional for the UE to support timeInfoUTC in SIB9 without UE capability signalling. It is up to SA WG4 to decide whether to use SIB9 for time synchronization for MBS. Action: RAN WG2 kindly asks SA WG4 and SA WG2 to take the information above into account.","secretary_remarks":"Received at meeting.
