Performance Evaluation in Heterogeneous Networks Employing Time-Domain Inter-Cell Interference Coordination and Cell Range Expansion for LTE-Advanced Downlink

Autor: Masashige Shirakabe, Nobuhiko Miki, Akihito Morimoto

Publikováno v: IEICE Transactions on Communications. :1218-1229

In Long-Term Evolution (LTE)-Advanced, heterogeneous networks where femtocells and picocells are overlaid onto macrocells are extensively discussed in addition to traditional well-planned macrocell deployment to improve further the system throughput.

Investigation on Interference Coordination Employing Almost Blank Subframes in Heterogeneous Networks for LTE-Advanced Downlink

Autor: Akihito Morimoto, Nobuhiko Miki, Tetsushi Abe, Masashige Shirakabe, Yuya Saito

Publikováno v: IEICE Transactions on Communications. :1208-1217

This paper investigates the application of inter-cell interference coordination (ICIC) in heterogeneous networks for the LTE-Advanced downlink where picocells are overlaid onto macrocells. In LTE-Advanced, in order to perform ICIC, almost blank subfr
