Joint Femtocell Clustering and Cross-tier Interference Mitigation with Distributed Antenna System in Small Cell Networks
Massa Ndong, Takeo Fujii (Univ. of Electro-Comm.) SR2013-21
Abstract (in Japanese) (See Japanese page) 
(in English) Small cell networks improve the spectral area efficiency of macrocells.
The femtocells overlaid onto macrocell constitute an underlay system instance
of small cell network whose performance is limited by the cross-tier interference
of the macrocell users. This study proposes a cooperative cellular architecture
composed of a distributed antenna system (DAS) and the femtocell-macrocell
underlay system. By distributing the remote antenna units of the DAS in the
two-tier network, the cross-tier interference can be mitigated at the femtocells
experiencing the interference of near macrocell users. The cross-tier
interference mitigation is applied on femtocells clustered by the DAS. The
proposed joint cross-tier interference mitigation and femtocell clustering
ensures a better average capacity across all end users in the two tier network.
The simulation results show that with our proposal, more than 90% of the
two-tier network users get an average capacity larger compared with
conventional femtocell-macrocell network where almost all users obtain a lower
average capacity.
