3GPP Finalizes 6G Release 21 Standards Timeline

3GPP Sets 6G Release 21 Roadmap, Targeting Full Specifications by Early 2029 

SINGAPORE — July 20, 2026 — The 3rd Generation Partnership Project (3GPP) has formally finalized the development timeline for Release 21, the first official 6G standards release, following its plenary meeting held in Singapore in June 2026. The milestone marks a pivotal step in the global race toward next-generation wireless connectivity, with full 6G specifications now targeted for completion in early 2029. 

Main Development 

The 3GPP plenary in Singapore confirmed a structured multi-stage roadmap for Release 21, establishing binding milestones that will govern the global 6G standardization process. The Stage-1 freeze — covering service requirements and use case definitions — is scheduled for March 2027, followed by a Stage-2 freeze in June 2028, and a final specification completion in early 2029. 

Alongside the timeline confirmation, the plenary also resolved key technical decisions on the 6G air interface, including waveform selection and spectrum framework parameters. These decisions are considered foundational to enabling commercial 6G deployments, which industry stakeholders broadly anticipate will begin around 2030. 

The formalization of Release 21 signals a transition from research and study phases into normative specification work, a shift that is expected to accelerate investment and ecosystem development across chipmakers, network equipment vendors, and mobile operators globally. 

The 6G market, according to Next Move Strategy Consulting, is projected to reach USD 41.42 billion by 2030, reflecting the accelerating commercial momentum behind next-generation wireless infrastructure. 

Key Highlights: 

• 3GPP finalized the Release 21 development timeline at its June 2026 plenary meeting in Singapore, marking the official launch of 6G normative standardization. 

• Stage-1 freeze is set for March 2027, Stage-2 freeze for June 2028, with full 6G specifications targeted for early 2029. 

• Key 6G air interface decisions — including waveform and spectrum framework — were confirmed at the Singapore plenary. 

• The global 6G market is projected to grow from USD 5.20 billion in 2023 to USD 41.42 billion by 2030, per Next Move Strategy Consulting. 

Analyst Insight: 

According to analysts at Next Move Strategy Consulting, the global 6G market is driven by rising demand for ultra-low latency connectivity, AI-native network architectures, and expanded spectrum utilization. The formalization of 3GPP's Release 21 timeline is expected to serve as a critical catalyst for enterprise investment, regulatory alignment, and supply chain preparation across the global telecommunications ecosystem. 

Industry Outlook: 

With 3GPP's Release 21 roadmap now formally established, the global telecommunications industry enters a decisive phase of 6G development. Equipment manufacturers, semiconductor firms, and mobile network operators are expected to intensify standardization participation and infrastructure planning over the 2026–2029 window. Regulatory bodies across major markets — including the United States, European Union, China, Japan, and South Korea — are anticipated to align national spectrum policies with the 3GPP timeline, setting the stage for coordinated commercial 6G launches in the early 2030s.
