The prime reason here is MBSFN operation. SA4 understands that the 5MBS feature does not yet have a requirement for synchronization across adjacent cells, but that the related RAN normative work item does not preclude its introduction in a later release. Does SA2 have any view on the need of SYNC and\/or RoHC support in the MBSF-U?\u201d\nRAN3 feedback: RAN3 already agreed that no SYNC protocol is supported in release 17.","secretary_remarks":"R3-211296","agenda_item_sort_order":69,"ainumber":"12","ainame":"LSs received during the meeting and Postponed Liaisons (from A.
