Guest Editorial: Special Section on Advancements for 6G

What will the wireless networks of the next generation look like? The latest advances in industrial and academic research have shed some light into that direction. With the finalization of the framework recommendation for the 6th generation (6G) networks by the International Telecommunication Union (ITU), the pillar usage scenarios, supporting capabilities and technical enablers are becoming clearer. The overarching motivation for the development of 6G is to continue to build an inclusive information society in a sustainable way. In this context, a range of user and application trends are foreseen to become an integral part of 6G, including ubiquitous intelligence, immersive multimedia and multi-sensory interactions, digital twins, digital health, smart industries, ubiquitous connectivity, integration of sensing and communication, as well as sustainability. It is worth noting that many of the trending demands do not come from the traditional markets for private mobile users and instead, they are driven by strong needs from vertical industries including manufacturing, transportation, and health care.
