Abstract:

Following the large-scale 5G commercialization, major countries and regions in the world have launched 6G R&D to seize the dominance in the development of next-generation mobile communications. At present, IMT industry is actively discussing 6G vision and key technologies, but no final conclusion yet. This paper presents usage scenarios that 6G may provide in the future, the expected main key capability indicators, and the key technical directions that need to be considered to support the realization of typical scenarios and capability indicators. The paper also provides the analysis of the innovative potential technologies that IMT industry currently focuses on, such as the integration of artificial intelligence(AI) and wireless communication, the integration of sensing and communications, intelligent reconfigurable surfaces(RIS), Terahertz communications technology, and wireless network architecture. Those future research directions are proposed for the industry’s reference.
