Mobile Xhaul Network for 5G RAN Evolution

Huyn Kyu Chung, ETRI, Korea

For 5G mobile communication services, it is expected that small cells will be more densely deployed and moving network could be a key feature to accommodate various 5G service requirements. Based on these technical trends, it is necessary to study technical solutions to support network mobility and to provide wireless connectivity to functional entities within radio access network (RAN) with scalable and flexible manner. In this talk, the Mobile Xhaul Network (MXN) will be introduced which is the ongoing research project as a way to provide wireless transport connectivity to 5G RAN including moving cell via Xhaul link consisting with front-haul, mid-haul and backhaul. Currently, the MXN project is focusing on network architecture and essential radio transmission technologies such as MIMO and beamforming with millimeter wave on 28GHz frequency band. In this talk, as a preliminary study of MXN, a wireless backhaul solution for moving network, called Mobile Hotspot Network (MHN) will be introduced, which is one of candidate technologies for mobile backhaul commercial solutions in the metro environment in Seoul, Korea.

Architecture and Implementation of Multi-Antenna Communication Systems for 5G Networks

Karl Nieman, National Instruments, USA

Multi-antenna technologies are a key enabler of 5G’s ambitious goals to drastically enhance network capacity and quality of service. In sub-6 GHz bands, MIMO dimensions must considerably scale to more efficiently use limited spectrum. In above-6 GHz bands, beamforming and hybrid MIMO architectures are essential to overcome propagation losses and achieve cost-effective deployments. In both cases, it is necessary to support wide system bandwidths and a multitude of other requirements that contribute to higher system complexity versus 4G predecessors. In this talk, I will discuss some of these challenges as they pertain to the development and implementation of real-time, multi-antenna 5G system prototypes. Specifically, I will cover details of achieving real-time performance with high MIMO dimensions and bandwidths by implementing distributed, high-throughput signal processing in a unified hardware and software framework. I will share lessons learned in system design and over-the-air results from several industry and academic partners who have adopted our platform.
