Spectrum sharing technology optimizes the usage of li-censed spectrum. Macrocell
underlaid with femtocells constitutes a typical two-tier network for improving spectral …

This paper investigates spectrum resource coordination for the mixed macrocell and
femtocell deployment. Though sharing spectrum provides larger bandwidth for both …

Femtocells are deployed in the coverage area of traditional macrocell networks and can
provide high data rates and good quality of service with low transmission power. In order to …

Spectrum sharing usage in two-tier networks mitigates spectrum scarcity and contributes in
satisfying the growing demands for wireless broadband. This paper addresses the Uplink …

Deploying femtocells faces a major challenge of causing downlink interference to the
existing macrocell. This paper proposes an intelligent spectrum sharing mechanism for a …

Femtocells widely deployed in a macrocell form hierarchical cell networks, which can
improve indoor coverage and network capacity, and have been regarded as one of the most …

We consider cross-tier interference management in heterogeneous networks with femtocells
overlaid onto macrocells. We propose a variation of the cellular architecture and introduce a …

Femtocell is on the way of being extensively deployed in households to provide better
indoor coverage and higher user capacity. However, as the coverage of femtocell is …

Two-tier femtocell networks, consisting of a conventional cellular network underlaid with
femtocell hotspots, play an important role in the indoor coverage and capacity of cellular …

This paper considers the cross-layer and co-layer interference in small cell networks. We
propose an interference management scheme by jointly optimizing user association, ABS …
