Abstract
he unsupervised and chaotic deployment of Home
eNBs (HeNBs) is leading to high levels of interference. To under-
stand the behaviour of the interference of these uncoordinated
deployments is vital to reach significant capacity improvement
and also to explore some opportunity for any energy reduction.
This paper considers scenarios with high interference and middle
interference levels, with a maximum of four users per cell. HeNBs
are deployed indoor in order to cover a building. We theoretically
analyse the traffic performance of this scenario through the
study of the Signal to Interference plus Noise Ratio (SINR).
Through the use of the LTE-Sim simulator one obtains the quality
indicators for two flows that are being utilised by the users. Video
and one best effort are studied, while varying the transmitter
power and the areas of the apartments.
The achieved SINR is higher when the area of the cells is
smaller. The variation of the transmitter power of the HeNBs
does not present any significant impact. Noticeable throughout
the simulations is observed that is possible to operate the system
without setting the transmitter power of HeNBs to the maximum
value at both interference levels. Simulation results also show
that with the considered flows is possible to serve the maximum
number of four users per HeNB with high quality. Take in
account the obtained results it is possible to promote a reduction
in energy consumption of the HeNBs without penalizing the
service quality.
