Within the foreseeable future, the growing number of mobile devices, and their diversity, will
challenge the current network architecture. Furthermore, users will expect greater data rates …

One of the effective techniques of improving the coverage and enhancing the capacity and
data rate in cellular wireless networks is to reduce the cell size (ie, cell splitting) and …

Femtocell architecture involves the use of two separate layers-the macrocell and femtocell
layers. In this architecture, the former is the conventional cellular network, whereas the latter …

Improvement of cell coverage and network capacity are two major challenges for the
evolving 4G cellular wireless communication networks such as LTE-Advanced networks. In …

To meet the demand of increasing mobile data traffic and provide better user experience,
heterogeneous cellular networks (HCNs) have become a promising solution to improve both …

This letter proposes a novel graph-based multi-cell scheduling framework to efficiently
mitigate downlink inter-cell interference in small cell OFDMA networks. This framework …

In recent years, the joint configuration of communication, computing and popular content
resources in wireless networks has been gaining an increasing amount of attention to …

Abstract A 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) system
uses the concept of two-tier heterogeneous networks (HetNets), where low-power and short …

The coexistence of omnidirectional small cells (OSCs), such as RF small cells, and
directional small cells (DSCs), such as visible-light communication cells, is investigated. The …

Unlike the fairness of the number of allocation units studied in the previous works, the
fairness of user satisfaction needs to consider the data rates on allocation units. In this …
