Abstract :
In this paper, the spectrum efficiency for four scenarios: baseline, cell split, fixed relay and dedicated mobile relay on vehicle are analyzed and compared in terms of unified spectrum efficiency bps/Hz/km2. The theoretical expression is derived and the capacity is calculated by numerical integration based on the parameters for 3GPP LTE-advanced system. The deployment costs for different scenarios are also estimated based on the current real network. This comparison can clearly show the benefit and cost of different solutions, and this is helpful for the strategy making.
