Understanding 3GPP Standards and the Path to 6G

Introduction

The 3rd Generation Partnership Project (3GPP) is the global standards body that defines the technical specifications for mobile telecommunications. Every mobile technology from 3G through 5G has been standardized by 3GPP, and it will lead the development of 6G specifications. Understanding 3GPP's process and timeline is essential for anyone in the telecommunications industry.

How 3GPP Works

3GPP organizes its work into "Releases," each containing a set of features and specifications. The process involves study items (research and feasibility), work items (specification writing), and approval. Hundreds of companies contribute through Technical Specification Groups (TSGs) covering RAN, Services & System Aspects, and Core Network & Terminals.

Current and Upcoming Releases

• Release 18 (2024): First 5G Advanced release with AI/ML for NR air interface
• Release 19 (2025): Enhanced 5G Advanced with expanded AI features
• Release 20 (2026-2027): Final 5G Advanced, bridge to 6G
• Release 21 (2029-2030): Expected first 6G specification

AI in 3GPP Standards

3GPP is progressively integrating AI into its specifications. Release 18 introduced study items on AI/ML for the air interface including beam management, positioning, and CSI feedback. Release 19 expands this with mobility optimization and more. This incremental approach builds toward the fully AI-native architecture expected in 6G.

How to Follow 3GPP

Stay updated by monitoring 3GPP meeting reports, reading Technical Reports (TRs) for study items, and following industry analysis from organizations like 3GPP itself, GSMA, and research firms. Many 3GPP documents are publicly available on the 3GPP portal.

Conclusion

3GPP standardization is the process through which research ideas become commercial reality. Understanding this process helps professionals anticipate industry direction, contribute to standards, and align product development with upcoming specifications.
