SMARTER DEVICES
Earlier generations of cellular systems were built on the design premise of having complete control at the infrastructure side. In this section, we discuss some of the possibilities that can be unleashed by allowing the devices to play a more active role and then how 5G’s design should account for an increase in device smartness. We focus on three different examples of technologies
that could be incorporated into smarter devices: D2D, local caching, and advanced interference
rejection.
