New Directions in Technology Innovations for 5G and Beyond
This talk aims to highlight the major advances in technologies that will enable 5G meet its objectives. Description of major new RAN technologies for 5G systems will form the first part of the talk. The second part will constitute the description of future CN technologies and the resulting flexible network architecture solutions leveraging the confluence of IT and telecommunications. More specifically, the first part will detail PHY layer technologies such as Enhanced MIMO, Massive MIMO (also known as Large Scale Antenna Systems), mmWave ultra broadband transmission techniques and air interface adaptations for efficiently handling the massively parallel access in sensor networks for IoT applications. Networking solutions based on intra and inter technology Heterogeneous Networks (HetNets) as well as Cloud RAN architectures will also be presented. The latter part will go into the details ofvirtualization and SDN by covering such topics as the benefits of virtualization, potential architectures and ecosystems, standards activities targeting SDN/NFV in 5G networks, and some selected use cases of (and roadmaptowards) NFV deployments. This talk will be concluded with a brief description of open research and technology challenges for implementation of future generation networks.
