Abstract

In the next generation of wireless networks, small base stations are being adopted to increase the system’s speed and
capacity. However, this adoption increases the likelihood of inter-cell interference, which can degrade performance the
system. This report discusses different approaches to managing interference that can mitigate these effects. Currently, a
few techniques are already in use in 4G systems, while others have been suggested but not put into practice. The purpose
of this study is to conduct an analytical examination of the different and various interference management methods that
could be utilized in Heterogeneous Networks (HetNets), focusing specifically on HetNets with high density of small cells
as they are expected to be part of the network topology for 5G networks and beyond. The study involved implementing
time-based enhanced inter-cell interference coordination (eICIC) by establishing coordination between macro and small
base stations. The results showed that robust communication with low latency is essential, and backhaul connections play
a critical role in achieving this. Consequently, the network’s sum-rate was increased.
