Abstract
Insightful choice of enabling technologies tend to effectuate a smooth transition from legacy networks to fifth generation wireless communication systems (5G). Future wireless networks must address exponential growth in connectivity, capacity and services, while perpetuating energy and cost reductions. It is therefore, crucial to intelligently evaluate key contenders of 5G evolution. This article provides an overview of ten fundamental concepts that could impact 5G framework. An outline of expected benefits is deliberated in this paper. We discuss compelling need of a new spectrum followed by associated changes in terms of air interface, architecture and MAC layer protocols. For alleviating access complexity in diverse-dense 5G deployment, we make a review on Heterogeneous-Cloud Radio Access Networks and Software Defined Networking. We also discuss two disruptive approaches with high research challenges, non orthogonality and full duplex.
