In this paper, we address the problem of optimizing resources for downlink transmission in a
macro–femtocell network under non-dense femtocell deployment. In the literature, some …

In this paper, we consider the problem of resource allocation in non-dense macrocell–
femtocell networks. We build a comprehensive realistic framework that overcomes the …

Femtocell system is expected to bring significant improvement of system performance with
low cost. However, when a number of femto BSs are installed by users without cell-planning …

Femtocells have been considered as a promising technology to provide better indoor
coverage and spatial reuse gains. However, the co-channel deployment of macrocells and …

Femtocells, combined with orthogonal frequency division multiple access (OFDMA), can
improve cellular coverage and offload traffics from existing macrocells. However, the co …

Two‐tier femtocell networks, in which a large number of femto base stations (BSs) are
deployed within a region overlapping with a macrocell, can provide an economical means of …

In this paper, we consider the problem of resource allocation in two-tier networks taking into
consideration nondense femtocell deployments. The following limitations can be remarked …

In this paper, we propose a base station selection and resource allocation model for OFDMA
macro-femtocell networks. Dense deployment of femtocells can cause severe interference …

Femtocells can be employed as the low-power “green” wireless-access points to extend the
macrocell network coverage and enhance the quality-of-service inside homes. In this paper …

In order to develop a completely distributed resource allocation scheme to improve data
rates and mitigate mutual interference across orthogonal frequency-division multiple access …
