A cluster based scheme for interference mitigation in mobile macrocell-femtocell networks
In this paper, we consider a power control scheme for co-channel deployment of femtocells in the umbrella of macrocell LTE. The severe interference in the downlink from the femtocells should be controlled to guarantee the Quality of Service (QoS) required by the macrocell users. We used clustering method for grouping femtocells according to their geographical localizations. For this scenario, we proposed a hybrid scheme that combines both centralized and distributed schemes to minimize the total power consumption at femtocells, while guaranteeing the QoS of their users. Simulation results showed that our proposed power scheme can allocate power efficiently on the resource blocks in femtocells while obtaining a small performance reduction in femtocell compared to the fully distributed scheme. As well, our method minimized the signaling overhead compared to the fully centralized power allocation scheme.
