Cell Range Expansion (CRE) is a promising solution to offload macrocells' traffic and improve the radio capacity in Heterogeneous Network (HetNet). On the other hand, enhanced Inter-Cell Interference Coordination (eICIC) techniques are introduced in HetNets to mitigate the severe interference caused between the small cells and the macrocell. In this paper, we present a novel application of the CRE...
Femtocells are new devices that are recently developed to address the poor indoor coverage of the 3G cellular network and beyond. This solution may, however, cause significant interference in the system. In our paper, we propose a new approach based on game theory which aims at enhancing the femtocells' capacity in a HSDPA network while mitigating the interference impact on the macro users' quality...
In this paper, we propose a new dynamic frequency assignment scheme for femtoCells in OFDMA networks. The femtoCell base stations are small cellular base stations specially designed to improve the poor indoor coverage and increase the system capacity for cellular and wireless broadband networks. However, these femto-base stations cause harmful interference to the macroCells. Therefore, the optimization...
