Edge Caching in Dense Heterogeneous Cellular Networks with Massive MIMO Aided Self-backhaul
Lifeng Wang, Kai-Kit Wong, Sangarapillai Lambotharan +2
This paper focuses on edge caching in dense heterogeneous cellular networks (HetNets), in which small base stations (SBSs) with limited cache size store the popular contents, and m…
A New Look at Physical Layer Security, Caching, and Wireless Energy Harvesting for Heterogeneous Ultra-dense Networks
Lifeng Wang, Kai-Kit Wong, Shi Jin +2
Heterogeneous ultra-dense networks enable ultra-high data rates and ultra-low latency through the use of dense sub-6 GHz and millimeter wave (mmWave) small cells with different ant…
Wireless Powered Dense Cellular Networks: How Many Small Cells Do We Need?
Lifeng Wang, Kai-Kit Wong, Robert W. Heath +1
This paper focuses on wireless powered 5G dense cellular networks, where base station (BS) delivers energy to user equipment (UE) via the microwave radiation in sub-6 GHz or millim…
