In April of 2016, 3GPP began to study a New Radio (NR) access technology also known as 5G. An early drop of the 5G NR specifications is due in December 2017 with the full set of features targeted for June 2018. Nevertheless, draft versions of the 5G NR specifications are already being circulated by the respective editors and reviewed by the respective 3GPP working groups. This tutorial style seminar will give a brief introduction of the key technologies and features of the 3GPP 5G NR specifications, particularly focusing on the physical layer aspects of the proposed standard. After a general description of the 5G NR access network and physical layer, the 5G NR physical channels and signals are introduced in detail as well as the associated physical layer procedures and measurements. Contrary to fourth generation cellular communications systems such as the LTE air interface of the evolved UMTS terrestrial radio access network (EUTRAN), the 5G NR air interface has been specifically designed for spectrum beyond 6GHz. The tutorial will thus also include a technology overview of beamforming, beam management, multiple-input/multiple-output (MIMO) techniques, coordinated multi-points (CoMP), and HARQ/scheduling for mmWave systems.



Dr. Ralf Bendlin is a Principal Member of Technical Staff at AT&T Labs in Austin, Texas. Before joining AT&T Labs, he was a Member of Technical Staff with Intel Corporation in Portland, Oregon (Senior Wireless Systems Architect) and with Texas Instruments Inc. in Dallas, Texas (Systems Engineer). He has worked on algorithm development, performance prediction, optimization, systems architecture, and technology strategy for current and next-generation wireless networks and has actively participated in the definition of several global communications standards for which he holds several patents. Dr. Bendlin holds a Bachelor’s degree and a Master’s degree from the Munich University of Technology in Munich, Germany as well as a Master’s degree and a Ph.D. from the University of Notre Dame in South Bend, Indiana. All degrees are in Electrical Engineering and Information Technology. He currently is a Guest Editor of the IEEE Transactions on Cognitive Communications and Networking (TCCN) and a member of the College of Engineering Advisory Council at the University of Notre Dame and has previously served as the Technical Program Chair of the 2017 IEEE International Symposium on Dynamic Spectrum Access Networks.
