The 3GPP finalized architectural specifications for 6G and reached total completion of Stage 2 requirements for 5G Advanced Release 20. These agreements set the foundation for future network standards during the plenary meetings held in September 2026.
Why it matters
Defining these technical parameters is essential for the global telecommunications industry to transition toward the 6G era. These standardized specifications allow manufacturers and carriers to align their long-term development roadmaps.
The organization achieved 100% completion of its Stage 2 architectural requirements for 5G Advanced Release 20. Additionally, groups finalized TR 38.914 baselines and system-level flows for Integrated Sensing and Communications.
The players
3GPP
This is a global partnership project that establishes technical specifications for mobile telecommunications systems.
ATIS
The Alliance for Telecommunications Industry Solutions is a North American standards body that facilitates the submission of network technology proposals to international regulators.
ITU-R WP 5D
This is a working party within the International Telecommunication Union responsible for the overall radio system aspects of terrestrial mobile networks.
The details
During the Madrid meetings, delegates established 6G dual connectivity paths using Option 1 and Option 3 while formalizing TR 22.870 for service requirements. Working groups also completed preliminary performance evaluations for Multi-RAT Spectrum Sharing to guide future technical report development.
Timeline
September 15-17, 2026: The 3GPP Plenary meeting occurred in Madrid.
Mid-2027: ATIS will submit initial framework structures to the ITU-R.
December 2028: The Release 21 functional stage 3 freeze is expected.
February 2029: This date marks the final deadline for IMT-2030 evaluations.
The Tech Race
The 3GPP architectural decisions follow the requirements set forth by the ITU-R IMT-2030 framework for next-generation network development. This standardization marks a shift from 5G expansion to the foundational phase of the global 6G arms race.
These specifications eventually determine the reliability and speed of future mobile data, though consumers will not see immediate changes to current devices. Standardized protocols ensure that 6G technology remains interoperable across global markets, lowering potential costs for future network hardware.
The takeaway
The formalization of 6G architecture marks the end of preliminary discussions and the start of structured technical development for the next decade. Industry observers should monitor ATIS filings in 2027 as the primary indicator of how these global standards will integrate into commercial networks.
What happens next
ATIS is scheduled to submit its initial framework to the ITU-R WP 5D in mid-2027, followed by a formal 6G candidate technology proposal due in early 2029.
