Relaying is a well-known technology that has gained a wide interest in the academic papers over the past years. It provides the advantages of enhanced throughput and extended coverage. However, most of the previous studies focused on fixed relay scenarios. Mobile Femtocell or MFemtocell can be considered as a practical implementation of the concept of the mobile relay. We investigate the impacts of deploying Mobile Femtocell in LTE networks. A possible protocol framework for MFemtocell deployment is suggested. The spectral efficiency performance of opportunistic multiuser scheduling algorithms over MFemtocell-enhanced LTE cellular networks is studied. Furthermore, we particularly study the impacts of deploying MFemtocells stations on the signalling overhead for opportunistic scheduling. In order to investigate the potential of MFemtocell in an LTE network, a dynamic system-level LTE simulator has developed. Our system level simulation results indicate that one potential advantage of deploying MFemtocells is improving spectral efficiency by reducing the amount of feedback signalling.
