Abstract

Massive multiple input multiple output (MIMO)
and full duplex (FD) communication are being considered as
potential candidates for the spectrum efficient 5G wireless networks.
In this paper, we develop a tractable model for downlink
(DL) and uplink (UL) transmission in K-tier heterogeneous
cellular networks (HCNs) with massive MIMO macrocells and
full duplex (FD) small cells for spectrum efficiency. In the
considered HCNs, the performance of the mobile user (MU) is
limited by several sources of interference, specifically due to FD
nature of small cell base stations (SBSs). A stochastic geometry
based model of the proposed HCNs is provided which allows
to derive the DL and UL rate coverage probabilities of such a
system. Monte Carlo simulations confirm the accuracy of the
analytical results, while numerical results reveal that equipping
large number of MIMO antennas at macro base stations (MBSs)
enhances the DL rate coverage probability of a random MU in
HCNs. The results show that to achieve the maximum joint DL
and UL performance gain in HCNs with FD small cells, both
SBSs’ density and SBSs’ transmit power should be optimized.
Moreover, the UL performance can be improved by decreasing
the SBSs receivers sensitivity and increasing the UL power
control factor.
