Body 
The ITU-T Joint Coordination Activity for IMT2020 and Beyond (JCA IMT2020)
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 website.

The objective of the roadmap is to support IMT-2020 and beyond standardization
coordination. IMT-2020 and beyond are the important topics for our industry,
and many standardization-related activities are held in various entities.

The JCA is progressing this work in a form of roadmap of IMT2020 and beyond
standardization. JCA-IMT2020 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 5G and beyond 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 (FMC) and Information-Centric Networking
(ICN), machine learning and other activities that are strongly related to IMT
2020, we will reflect it in the next roadmap update, which will be performed
online soon after the next JCA IMT2020 meeting. In particularly, if you have
IMT-2030 related work, please kindly send us the information.

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 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 anticipates having its next meeting on 16 July 2025, 13:00- 14:30,
alongside the ITU-T SG13 co-located rapporteur group activities (14 – 25 July
2025) in Geneva. We invite your inputs/updates to the roadmap.
