To meet the extremely stringent but diverse requirements of 5G, cost-effective network
deployment and traffic-aware adaptive utilization of network resources are becoming …

Virtual small cell (VSC) formed by directional beams is seen as an alternative for the small
base station (SBS) within the coverage of macro base station (MBS), to increase system …

Large antenna arrays can be used to generate highly focused beams that support very high
data rates and reduced energy consumption. However, optimal beam focusing requires …

This paper builds on the UE-based Virtual Base Station (UE-VBS) concept, which enables
the Smartphones (ie, UEs) of the general population to be enhanced with Base Station and …

It is well acknowledged that one of the key enabling factors for the realization of future 5G
networks will be the small cell (SC) technology. Furthermore, recent advances in the fields of …

In order to exploit the potential capacity of 5G, the deployment of ultra-dense small cells is
an approach that can dramatically increase the radio resource reuse factor and network …

One of the envisaged candidates technologies to be used in next generation mobile
networks is the integration of a large number of antennas at the Base Station (BS), known as …

Densiflcation, energy efficiency and self optimizing network (SON) are key features to meet
the forecast requirements of fifth generation (5G) networks. Frequently, the major …

Abstract Ultra-Dense Network (UDN) is regarded as a major development trend in the
evolution of future networks, due to its ability to provide larger sum rate to the whole system …

Abstract Three-dimensional (3D) beamforming and higher order sectorization (HOS)
represent two fundamental features to boost the capacity of ultradense heterogeneous …
