In split spectrum macrocell-femtocell networks, certain portion of the available spectrum resources are dedicated to each tier in order to avoid interference problems among the tiers. In such a setting, effective partitioning of the spectrum resources carries critical importance for maximizing the total capacity and satisfying quality of service (QoS) requirements of the users within each tier. This...
Access configuration of femtocell networks carries critical importance due to the resulting interference scenarios. Especially in closed-access femtocell networks, there might be significant interference between the femtocell and the macrocell users. In this paper, we evaluate the capacity of closed access femtocell networks employing various dynamic spectrum reuse techniques. When there is a macrocell...
Open access is one of the access options for femtocell networks, where the mobile stations (MSs) are allowed to make hand-off to the femtocell base stations (fBSs) in their vicinity. In this paper, several performance trade-offs that are related to the deployment of open access femtocell networks are presented through computer simulations. In particular, first, impact of a capacity-based cell selection...
