Although global deployment of 5G is making solid progress and 3GPP Releases 17 and 18 will certainly enable more advanced 5G applications and use cases in the coming years, numerous operators, vendors, universities and other tech firms are already engaged in regional 6G research initiatives and some of them have already published white papers with some preliminary concepts about as-yet-unstandardized 6G technologies.
The Next G Alliance in North America, FutureForum in China, 6G-IA in Europe, 6G Forum in Korea and the Beyond 5G Promotion Consortium in Japan are some of the leading organizations that are currently working on the research phase of future 6G systems.
