We consider a heterogeneous cellular network (HetNet) where a macrocell tier with a large
antenna array base station (BS) is overlaid with a dense tier of small cells (SCs). We …

This letter investigates the uplink spectral efficiency (SE) of a two-tier cellular network, where
massive multiple-input multiple-output macro base stations are overlaid with dense small …

We propose a time division duplex (TDD) based network architecture where a macrocell tier
with a “massive” multiple-input multiple-output (MIMO) base station (BS) is overlaid with a …

This paper exploits the potential of massive multiple input multiple output (MIMO) in K-tier
heterogeneous cellular networks (HCNs), to enhance the data rate for 5G. In such a network …

In this paper, we study the downlink performance of a heterogeneous cellular network
(HetNet) where both macro and small cells share the same spectrum and hence interfere …

A heterogeneous network (HetNet) of a macrocell base station equipped with a large-scale
massive multi-in multi-out (MIMO) antenna array overlaying a number of small cell base …

To meet the challenging capacity requirement of 5G, a set of radio access technologies may
be needed, including technologies to improve the spectrum efficiency, to utilize more …

We develop a framework for downlink heterogeneous cellular networks with line-of-sight
(LoS) and non-LoS transmissions. Using stochastic geometry, we derive tight approximation …

Two key traits of 5G cellular networks are much higher base station (BS) densities-especially
in the case of low-power BSs-and the use of massive MIMO at these BSs. This paper …

We investigate the heterogeneous cellular network (HetNet) where the macrocell base
stations (MBSs) are equipped with very large antenna arrays. Since such a combined …
