讲座题目：Key Enabling Technologies for 5G Wireless Networks: Compressive Signal Processing, PHY Caching and Multi-timescale RRM
主讲人：An Liu（Research Assistant Professor, Hong Kong University of Science and Technology）
To meet the ever increasing wireless traffic demand, many new wireless technologies, such as massive MIMO, heterogeneous network, and cloud radio access network (C-RAN), have been proposed for future 5G wireless networks. These technologies can significantly improve the spectral efficiency by increasing the number of antennas or base stations (BSs) per unit area. However, they also suffer from huge implementation costs and more severe interference. In this talk, we propose a solution framework which contains three key technologies, namely the compressive signal processing, physical layer (PHY) caching and multi-timescale radio resource management (RRM), to address the aforementioned issues of 5Gwireless networks. For each technology, we will elaborate the motivation, the basic concepts, the technical challenges, and the solutions using example applications in 5G wireless networks. We will also discuss the potential impact on the industry and some new research opportunities.
