Abstract

The mobile femtocell (MFemtocell) is a new concept that has been recently proposed to be a potential wireless communication technology for next-generation cellular systems. The essence of MFemtocell lies in adopting the femtocell technology inside vehicles such as trains, buses, or private cars to provide better coverage and a good Internet experience while on the move. In this paper, we investigate the spectral and energy efficiency for the MFemtocell-Assisted network with different resource partitioning schemes. Closed-form expressions for the relationships between spectral efficiency and energy efficiency are derived for a link-level MFemtocell network. We also investigate the spectral efficiency for multiuser system-level MFemtocells with opportunistic scheduling schemes. Our analysis shows that MFemtocells can provide better spectral and energy efficiency compared with the direct transmission scheme.
