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 is one of promising key technologies to increase the efficiency and coverage of
next generation broadband wireless networks. However, there exists interference problem …

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 …

Relaying in femtocell networks is a promising and economically viable option to reduce the
co-channel interference while improving indoor coverage and the network capacity in the …

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 …

OFDMA femtocells in the macrocellular network of which frequency reuse factor is 1 cause
serious interference to macrocell users, while the femtocells improve the performance of …

In this paper, we address the problem of resource allocation under high user density
environment in OFDMA macro-femotcell networks. In the literature, several solutions have …

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

In this paper, we propose a novel scheme to improve the throughput of femtocell networks.
The proposed scheme consists of two steps: spectrum allocation for femtocells and dealing …

Orthogonal frequency division multiplex-based femtocell networks in downlink with two-tier
interference are considered in this paper. In order to satisfy the quality of service of …
