Recently, operators have resorted to femtocell networks in order to enhance indoor coverage and increase system capacity. Nevertheless, to successfully deploy such solution, efficient resource allocation algorithms and interference mitigation techniques should be deployed. The new applications delivered by operators require large amounts of network bandwidth. Whereas, some customers may want to pay more in exchange for a better Quality of Service (QoS), some others need less resources and can be charged accordingly. Hence, the authors consider an OFDMA femtocell network serving both QoS constrained High-Priority (HP) and Best-Effort (BE) users.
