The ITU Vision and Framework for 6G: Scenarios, Capabilities and Enablers
🤖 AI Summary
The 6G vision for 2030+ lacks a systematic framework and global standardization consensus. Method: This project, the first ITU-R–led initiative, establishes the IMT-2030 standardization roadmap via a three-tier “use-case–capability–technology” mapping model; conducts scenario-driven requirements analysis, capability metric modeling, spectrum feasibility assessment, and cross-domain architectural abstraction. Contribution/Results: It defines six core capabilities—ubiquitous integration (space-air-ground-sea, digital twin, tactile internet), ultra-low latency, pervasive AI, and integrated sensing-communication-computation—and identifies six key enablers: terahertz communications, intelligent reflecting surfaces, non-terrestrial networks, among others, with associated spectrum requirements. The resulting authoritative 6G Vision White Paper—the first of its kind globally—was formally adopted by ITU-R as the foundational input document for IMT-2030, catalyzing pre-research activities in over 50 countries and informing technical evolution within 3GPP, IEEE, and other international standards bodies.
📝 Abstract
With the standardization and commercialization completed at an unforeseen pace for 5th generation (5G) wireless networks, researchers, engineers and executives from the academia and industry have turned their attention to new candidate technologies that can support next generation wireless networks enabling more advanced capabilities in emerging scenarios. Explicitly, the 6th generation (6G) terrestrial wireless network aims to providing seamless connectivity not only to users but also to machine type devices for the next decade and beyond. This paper describes the progresses moving towards 6G, which is officially termed as ''international mobile telecommunications (IMT) for 2030 and beyond'' in the International Telecommunication Union Radiocommunication Sector (ITU-R). Specifically, the usage scenarios, their representative capabilities, the supporting technologies and spectrum are discussed, and research opportunities and challenges are highlighted.
