Despite the e-meeting challenges, SA2 continues to make good progress on Rel-18 work, thanks to the
meticulous SA2 work planning, technical document budget allocation per Time Unit (TU), and outstanding
effort of the meeting participants. At the time of writing, Rel-18 Study items are between 70% - 100% complete.
SA2 plans to finish the Stage-2 normative work by Mar 2023. Rel-18 Stage-3 target freeze date is Dec 2023 and
ASN.1/Code freeze target is Mar 2024.
