6G Technologies: Key Drivers, Core Requirements, System Architectures, and Enabling Technologies

The key drivers of 6G result not only from the challenges and performance limits that 5G presents but also from the technology-driven paradigm shift and the continuous evolution of wireless networks. Intelligent driving and industry revolutions create core requirements for 6G that will lead to service classes of ubiquitous mobile ultrabroadband (uMUB), ultrahighspeed-with-low-latency communications (uHSLLC), and ultrahigh data density (uHDD).
