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.
