5G aims to support new and diverse sets of application classes like eMBB communications, uRLLC and mMTC. Supporting these services using a single framework has introduced a new vision and sets of challenges for wireless researchers in many layers of the protocol stacks, especially in the Physical, Medium Access and Network Layers. The trend on the variety and the number of mobile devices along with the mobile applications will certainly continue beyond 5G. In order to create a system that can support this trend, a wide range of technical challenges and requirements must be simultanously satisfied. A robust system that ensures extreme reliability and low latency under diverse channel conditions, while minimizing production and operational costs and maximizing power and spectrum efficiency is required. Cooperative networking capability and coexistence, dynamic and flexible utilization of wireless spectrum, highly flexible, cognitive and adaptive radio access technologies are key enablers in addressing these technical challenges. In this talk, the potential directions and research opportunities to address the challenges and requirements of the 5G vision will be discussed.
