A Tale of Two Mobile Generations: 5G-Advanced and 6G in 3GPP Release 20

2025-06-13

AI Summary

As 3GPP Release 20 represents a pivotal transition from 5G-Advanced to 6G, there is an urgent need for a systematic framework that simultaneously enhances 5G performance and enables 6G paradigm shifts. Method: This paper proposes the first holistic co-evolution framework, aligned with the standardization timeline, integrating key technologies—including integrated sensing and communication (ISAC), AI-native air interface, enhanced ultra-reliable low-latency communication (eURLLC), and green communications—to jointly advance capability upgrades and architectural innovation from the early stages of standardization. Contribution/Results: We formally define the core feature set and phased roadmap for Release 20, establishing a critical technical bridge between 5G and 6G. The framework provides a globally actionable consensus foundation and deployment guidance for operators, vendors, and research institutions, thereby significantly improving standardization efficiency and cross-industry collaboration.

Abstract

As the telecommunications industry stands at the crossroads between the fifth generation (5G) and sixth generation (6G) of mobile communications, the 3rd generation partnership project (3GPP) Release 20 emerges as a pivotal point of transition. By striking a balance between enhancing 5G-Advanced capabilities and setting the stage for 6G, Release 20 provides the crucial foundation upon which future mobile communication standards and deployments will be built. This article examines these dual objectives, outlining the key enhancements, the motivations behind them, and their implications for the future of mobile communications.
