Macrocells may suffer serious uplink interference introduced by the deployment of co-
channel femtocells. In this paper, an interference-aware pricing-based resource allocation …

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 …

In this paper, we address the problem of subchannel, rate and power allocation in OFDM-
based two-tier femtocell networks, which comprise a conventional macrocell and multiple …

In femtocell networks, due to their small cell size, we can achieve higher spatial diversity
from the channel reuse between multiple femtocells. In addition, if femtocells are operated …

In this paper, we study power loading and resource allocation for OFDM-based femtocell
networks. To mitigate the interference to the macrocell from the femtocell, interference …

Femtocell networks, consisting of a conventional macro cellular deployment and overlaying
femtocells, forming a hierarchical cell structure, constitute an attractive solution to improving …

In this paper, we investigate the co-tier and cross-tier interference mitigation problem using
power control in a two-tier OFDMA femtocell network. By considering the femtocell base …

Deployment of femtocells have emerged as a promising technique to address the need for
the exponentially increasing mobile traffic demand. They can also improve the capacity and …

Femtocells have attracted more and more attention in academia, industry and
standardization forums. Besides, energy efficiency has been widely discussed in recent …
