5G air interface and network technology

Mobile communication has evolved significantly from early voice systems to today's highly sophisticated integrated communication platform. 4G LTE networks are deployed in more than 100 countries to provide service in various spectrum band allocations depending on spectrum regime. Recently, significant momentum has started to build around the idea of a next generation, i.e. fifth generation (5G), wireless communications technology. The next generation wireless communication system, 5G, will provide access to information and sharing of data anywhere, anytime by various users and applications. 5G is expected to be a unified network/system that target to meet vastly different and sometime conflicting performance dimensions and services. Such diverse multi-dimensional requirements are driven by different services and applications. Not that to address vastly diverse requirements, 5G will be the set of technical components and systems needed to overcome the limits of current systems. For mid-band (carrier frequency between 6GHz and 30GHz) and high-band (carrier frequency beyond 30GHz), beamforming is needed to compensate the large path loss and thereby improve the link budget and coverage. The beamforming from both eNodeB and UE can be used to further improve the system level performance. In this talk we will share our views on 5G air interface and network technology. In particular, we will discuss detailed aspects related to UE such as UE side beamforming.
