Query: Interference Mitigation Using Dynamic Frequency Re-use for Dense
  Femtocell Network Architectures   The next generation network aims to efficiently deploy low cost and low power
cellular base station in the subscriber's home environment. For the femtocell
deployment, frequency allocation among femtocells and macrocell is big concern
to mitigate the interference, and to ensure the best use of the expensive
spectrum. There are many sources of interference in integrated
femtocell/macrocell networks. Lagging in proper management of interference
reduces the system capacity, increases the outage probability, and finally
users feel bad quality of experience (QoE). The cost effective interference
management technique depends on the size of femtocells deployment. In this
paper, firstly we present deployable various possible femtocell network
scenarios. We propose the dynamic frequency re-use scheme to mitigate
interference for femtocell deployment. For highly dense femtocells, we propose
the functionalities of self organizing network (SON) based femtocell network
architecture. The outage probability of a femtocell user is analyzed in
details. The performances of the proposed schemes for various femtocell
deployments are performed using numerical analysis.
