Abstract

In this paper, we analyze whether mobile relay could bring capacity gain to a LTE-Advanced network. The analysis is based on the Shannon formula modified for LTE. The Spatial Poisson Process is used to model the distribution of terminals and mobile relays in the cell. We consider two relay modes in the study: pure-relay mode and femto-like mode. Through the analysis we get the conclusion that penetration loss is a key factor to decide whether mobile relay can bring considerable capacity gain into the system. When penetration loss is 25 dB, pure-relay mode can bring about +30% capacity gain compared with traditional mode, femto-like mode can bring almost +100% capacity gain compared with traditional mode.
