CYSE Tenure-Track Faculty Candidate Seminar #3: Artificial Intelligence-Driven 5G and Beyond Radio Access Networks (RANs)

Abstract

On contrary to previous generation mobile wireless networks, 5G and Beyond (B5G) wireless networks are expected to undergo an unprecedented transformation and revolutionize wireless evolution to support a wide variety of heterogeneous quality of service (QoS) provisioning, such as, mobile broadband, ultra-reliable low-latency communications, and massive machine connectivity etc. These multi-dimensional QoS requirements stem from exponential data traffic growth due to massive internet of things, autonomous vehicles, unmanned aerial systems, telehealth, AR/VR application, and many other, yet unknown use cases, such as, internet of everything. Consequently, B5G wireless networks, particularly, radio access networks (RANs) are becoming increasingly smart bringing in automation with artificial intelligence (AI) and machine learning technologies. In this talk, we discuss a few recent works where we designed AI techniques to solve key challenges in B5G RANs (especially, PHY and MAC layers). Following this, we briefly present an emerging industry-driven open radio access network (O-RAN) architecture that provides sufficient openness, flexibility, and well-defined interfaces to incorporate intelligence in RANs. We conclude this talk with an overview on the future outlook of the exciting area of AI-driven B5G RANs. Zoom Link: https://gmu.zoom.us/j/93131934658
