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.
