The ongoing densification of small cells, ie, ultimately evolving toward ultra-dense networks
(UDNs), yields an unprecedented paradigm shift in network design by bringing the base …

The small cell network (SCN) is one of the emerging technologies for the next generation
wireless systems. It can provide lots of advantages, such as enlargement of cell coverage …

In this paper, we consider a relative received link power (RRLP)-based coordinated multi-
point (CoMP) joint transmission (JT) in the multi-tier ultra-dense networks (UDN). In this …

Multi-tier cellular networks are considered as an effective solution to enhance the coverage
and data rate offered by cellular systems. In a multi-tier network, high power base stations …

This paper concerns a heterogeneous ultra dense network (HUDN) with regularly deployed
macrocells. Aiming to combat both cross-tier and co-tier inter-cell interference (ICI), this …

Ultra-dense networks (UDNs) are one of the key enabling techniques for implementation of
5G wireless communication systems, and inter-cell interference is a major issue in UDNs …

In ultra-dense networks (UDNs), distributed radio access points (RAPs) are configured into
small virtual cells around mobile users for fair and high-throughput services. In this …

Coordinated multipoint (CoMP) transmission is capable of significantly improving both the
cell average and cell-edge performance in terms of spectral efficiency (SE). It is therefore …

In this paper, we investigate the limitation of multi-user multiple-input multiple-output (MIMO)
in ultra-dense networks (UDNs) and investigate how to overcome the limitation by designing …

In this paper, we propose a general mathematical framework to compute the average
downlink rate in a multiple connectivity context considering ultra-dense network (UDN) …
