Stratification of 5G evolution and Beyond 5G

Abstract

The next decade will bring exciting transformation in physical, digital and biological worlds. While requirements and use cases for Beyond 5G (B5G) are not fully clear at this time, an attempt at stratification of 5G evolution and B5G has been developed. Such stratification, i.e., decomposition into candidate technologies, will include technology scenarios of 5G evolution to fully deliver on the most demanding of 5G requirements and use cases eventually as well as novel architectural and technology concepts to be broadly linked with 6G. With 6G, we may associate Terahertz (THz) spectrum-based radio access, network as a sensor, alternative compute architecture, edge centric and flow-based core architecture as well as design-time driven, automated and secure network of networks. Key attributes and characteristics of the associated technology scenarios are described.
