Open access is an efficient approach to reduce cross-tier interference in femtocell networks.
In this paper, we study resource allocation in open access OFDMA femtocell networks to …

In this paper, we propose a joint subchannel and power allocation algorithm for the downlink
of an orthogonal frequency-division multiple access (OFDMA) mixed femtocell/macrocell …

Femtocells that use co-channel allocation with macrocells can considerably increase
wireless coverage and system capacity, especially for indoor and cell-edge users. However …

Interference management and supporting quality‐of‐service (QoS) requirements are the
main challenges for the spectral resource allocation in orthogonal frequency division …

Both orthogonal frequency-division multiple access (OFDMA) and femtocell are promising
technologies providing subscribers with better services. However, due to the ad hoc nature …

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 …

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 …

Femtocells are being considered a promising technique to improve the capacity and
coverage for indoor wireless users. However, the cross-tier interference in the spectrum …

Femtocell technology has been drawing considerable attention as a cost-effective means of
extending cellular coverage and enhancing capacity as well as realizing its potential, when …

Joint consideration of interference, resource utilization, fairness, and complexity issues is
generally lacking in existing resource allocation schemes for Long-Term Evolution …
