English abstract:
The trade-off when simulating wireless cellular
networks is mainly between accuracy on the one side and
simulation time and supported maximum network size on the
other side. A common approach in system level (SL) simulations
is to utilize various abstractions that also include employing
propagation models, which can be parameterized by only a small
number of values. When investigating high speed train (HST)
scenarios, the distinct effects of this particular environment
have to be reflected in the chosen models. In order to verify
the validity of SL simulations in this context, we incorporate
the results of channel measurements, obtained in a real-world
train transmission scenario, in our SL simulations and compare
the obtained results to those of post-processed results obtained
directly through the measurement data. We show that despite
of the various abstraction steps in SL simulations, average
throughput results are in good accordance and general trends are
preserved. Additionally, we take advantage of the more flexible
SL simulations and investigate the influence of feedback delay
and jitter. In a last step, we then discuss the advantages of
introducing a channel quality indicator (CQI) feedback backoff,
in order to improve the reliability of the connection in this
