Body 
The ITU-T Joint Coordination Activity for IMT-2020 and IMT-2030 (JCA
IMT2020/IMT2030) thanks all that have replied to previous requests for input on
IMT-2020 and beyond related standardization work. The current online version of
the roadmap is available from the JCA-IMT2020/IMT2030 website
(http://www.itu.int/en/ITU-T/jca/imt2020/Pages/default.aspx).

In alignment with the new Terms of Reference of this JCA, the updated objective
of the roadmap is to support non-radio aspects of IMT-2020/IMT-2030
standardization and pre-standardization coordination. IMT-2020 and IMT-2030 are
the important topics for our industry, and many standardization-related
activities are held in various entities.

JCA-IMT2020/IMT2030 will keep updating this roadmap, and therefore we solicit
your information about updates. If you send us the latest information of your
activity related to IMT-2020 and IMT-2030 as well as Network Function
Virtualization (NFV), programmable networks, self-managed networks, autonomous
network, slicing (including orchestration and capability exposure),
fixed-mobile and satellite convergence (FMSC) and Information-Centric
Networking (ICN), digital twin network, AI/machine learning and other
activities that are strongly related to IMT 2020 and IMT-2030, we will reflect
it in the next roadmap update, which will be performed online soon after the
next JCA IMT2020/IMT2030 meeting.

Please submit your updates using the template to be found in appendix below. In
the last column of this template we expect to get a direct pointer to your
document and not to the website where one needs to search for your document.
Should you wish to communicate any additional information about your
specifications and projects, we invite you to do so. If you have a
representative that wishes to present at an upcoming JCA-IMT2020/IMT2030
meeting, please let us know.

In addition, if not done yet, we invite the ITU-T Study Groups, SDOs, fora to
nominate a representative to this group.

JCA-IMT2020/IMT-2030 anticipates having its next meeting on 24 June 2026, 13:00
- 14:30, alongside the ITU-T SG13 meeting (23 June – 2 July 2026) in Geneva. We
invite your inputs/updates to the roadmap and your presentations on your latest
IMT-2020/IMT-2030 progress.
