Fourth Generation (4G) cellular networks present a
number of improvements in the overall network performance.
However, and despite the advanced technologies that are being
employed, Inter Cell Interference (ICI) remains a constraining
factor. ICI Coordination techniques target the minimization of
ICI and have gained ground in the literature. The introduction
of dynamicity in these schemes results in even better
bandwidth utilization and enhances the overall performance.
In this work, we propose a distributed algorithm that performs
dynamic channel allocation to mitigate the ICI in cellular
scenarios applying Partial Frequency Reuse (PFR). In
particular, the algorithm is based on a Gibbs Sampler
mechanism that allows achieving an optimized performance.
Simulation results have shown that the proposed solution
reduces the network interference up to 13 dB with respect to
classical PFR. In addition, benefits have also been observed in
the user capacity, where our scheme achieves improvements of up to 43% in terms of average user capacity and up to 17% for
the users located at the cell edge.
