Cellular networks are becoming dense due to deployment of small cells and a number of
user devices. Such networks are called ultra-dense networks (UDNs). In this paper, we …

This paper considers the dynamic downlink spectrum resource allocation problem in dense
small cell networks. To address the problem, we propose a distributed downlink resource …

Ultra dense networks (UDN) can be considered as one of the key technologies of 5G, since
it can improve capacity and spectral efficiency. With the densification of cell networks, the …

Ultra dense network (UDN) technology will certainly be the key to the future development of
the fifth Generation (5G) mobile communication. In order to improve spectral efficiency and …

We present a method for parallel dynamic cell selection and link scheduling in order to
simultaneously activate a subset of non-interfering transmitter-receiver links to manage the …

Abstract A typical 5G Ultra-Dense Network (UDN) comprises different types of Base Stations
(BSs) in its structure. Dense deployment of small-cell BSs within a macrocell BS's coverage …

The most promising approach to enhance network capacity for the next generation of
wireless cellular networks (5G) is densification, which benefits from the extensive spatial …

Ultra-dense networks (UDNs) have become an important architecture for the fifth generation
(5G) networks. A large number of small base stations (SBSs) are deployed to provide high …

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 …

Cumulative distribution function (CDF)-based scheduling (CS) has been known as an
efficient technique for cellular networks, which satisfies arbitrary channel access ratio …
