The impact of user spatial heterogeneity in heterogeneous cellular networks [PDF]
2014 IEEE Globecom Workshops (GC Wkshps), 2014 The spatial distribution of users in cellular networks plays an important role on network performance. It is becoming increasingly common in the recent literature to model the user locations according to a homogeneous Poisson point process, yet users are often spatially clustered in reality.

Energy Efficiency Analysis in Cache-Enabled D2D-Aided Heterogeneous Cellular Networks
IEEE Access, 2020 Small cells (SCs) offer a promising approach to meeting the exponentially growing data rate demands. However, dense deployment of SCs can degrade the energy-efficiency (EE) of the network due to the additional deployed base stations (BSs).

Equivalence and comparison of heterogeneous cellular networks [PDF]
2013 IEEE 24th International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC Workshops), 2013 We consider a general heterogeneous network in which, besides general propagation effects (shadowing and/or fading), individual base stations can have different emitting powers and be subject to different parameters of Hata-like path-loss models (path-loss exponent and constant) due to, for example, varying antenna heights.

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.
