  Mobile communication technologies have been evolving for many years with each
generation transforming the way we experience new services. As the Smartphone
market has significantly expanded in recent years and expected to grow more in
years to come, the network evolution must continue to keep up the pace with
users demand even beyond the common usage connectivity. The envisioned market
space for the next generation technology is driven by requirements to enhance
mobile broadband connectivity, reach a massive range of machine type
communication (MTC), and target services with ultra-reliable and low latency
(URLLC) communications. To deliver these requirements, 5G must be designed with
scalability and diversity across many components from spectrum, core network,
radio access and devices
