The future of connectivity is in the creation of digital twin worlds that are a true representation of the physical and biological worlds at every spatial and time instant, unifying our experience across these physical, biological  and digital worlds. Evolution of technologies for sensing, ubiquitous computing, knowledge systems, and man-machine interfaces will in turn drive the need for new connectivity requirements and  technologies. We present our view on drivers and requirements for 6G connectivity to enable the ‘augmented human’, capable of experiences decoupled from the physical location, intelligence expanded with the network providing a sixth sense, and empowered to control machines from the digital world.

We will then discuss the  major technology transformations that are likely to define 6G: (i) AI/ML optimized air-interface; (ii) cognitive spectrum sharing methods and new spectrum bands; (iii) native integration of sensing with communication, (iv) the achievement of extreme performance requirements on latency and reliability; (v) new network architecture paradigms involving sub-networks and RAN-Core convergence; and (vi) new security and privacy schemes.
