English abstract:
In this paper, we investigate the impact of various re-
mote unit collaboration schemes on the transmission performance
to passengers, traveling in high speed trains. We assume that the
user equipments directly communicate with the remote units,
i.e., the trains are not equipped with relay nodes. We introduce
a theoretical model based on Maximum Ratio Transmission and
Gamma distributed fading, and analyze a representative segment
of a railroad track. Results from both, theory and simulations
by the Vienna LTE-A System Level Simulator are provided in
terms of train average spectral efficiency and allow us to discuss
the suitability of the moving cell concept for trains without
relay support. Our theoretical results exhibit an offset from
the simulations. Investigating its origin reveals the limitations of
codebook-based precoding and allows us to adapt our theoretical
model for accurate performance predictions.
