Analysis on Cache-Enabled Wireless Heterogeneous Networks [PDF]
IEEE Transactions on Wireless Communications, 2016 Caching the popular multimedia content is a promising way to unleash the ultimate potential of wireless networks. In this paper, we contribute to proposing and analyzing the cache-based content delivery in a three-tier heterogeneous network (HetNet), where base stations (BSs), relays and device-to-device (D2D) pairs are included.

Design of a Heterogeneous Cellular Network With a Wireless Backhaul [PDF]
IEEE Transactions on Wireless Communications, 2017 The downlink of a two-layered heterogeneous network is studied with macro basestations (MBs), small-cell basestations (SBs) that act as half-duplex analog relays, and mobile terminals (MTs). The first layer is a wireless backhaul layer between MBs and SBs, and the second is the transmission layer between SBs and MTs.
