This paper proposes a decentralized model for the allocation of modulation and coding
schemes, subchannels and transmit power to users in OFDMA femtocell deployments. The …

Recently, operators have resorted to femtocell networks in order to enhance indoor
coverage and quality of service since macro-antennas fail to reach these objectives …

Femtocells have attracted growing attentions in academia, industry, and standardization
forums in recent years. In this paper, we investigate a distributed radio resource allocation …

This paper presents a framework based on self-organization to jointly self-optimize the
spectrum assignment and the transmission power in the context of downlink OFDMA …

In order to improve the spectrum efficiency in the femtocell network and mitigate the co-
tier/cross-tier interference, we propose a novel graph-theoretic scheme based on coloring …

Femtocells offer many advantages in wireless networks such as improved cell capacity and
coverage in indoor areas. As these femtocells can be deployed in an ad hoc manner by …

This paper proposes a distributed joint subchannel and power allocation algorithm for the
downlink of an orthogonal frequency-division multiple access (OFDMA) mixed …

This paper focuses on the task of spectrum assign-ment and the transmission power in the
context of downlink OFDMA femtocell deployments. Concretely, the paper studies the impact …
