5G rollouts have stimulated new demand that cannot be met by 5G itself. That's where 5G-Advanced comes into play, delivering enhanced capabilities. Without a doubt, 5G-Advanced will further stimulate more new demands that only 6G can address. Looking into these new demands will be crucial to defining 6G. ITU-R is leading the consortium effort to study future technology trend (FTT) and 6G vision, aiming to issue the FTT report and vision recommendation by the end of 2022 and in the middle of 2023, respectively. 6G will go far beyond communications. 6G will serve as a distributed neural network that provides communication links to fuse the physical, cyber, and biological worlds, truly ushering in an era in which everything will be sensed, connected, and intelligent. In addition to connected people and things, we predict that 6G will be the platform for connected intelligence, where the mobile network connects vast amounts of intelligent devices and connects them intelligently. This talk will first start with 5G-advanced as an introduction, then present an overall vision for 6G with drivers, use cases, KPIs, roadmap and key capabilities. Six key capabilities: (1) Extreme connectivity, (2) Native AI, (3) Networked sensing, (4) Integrated Non-terrestrial network, (5) Native trustworthiness and (6) Sustainability, will be further discussed, including potential technologies/research directions and associated challenges.
