This paper proposes a Self-organized Spectrum
Assignment strategy in the context of next generation multicell
Orthogonal Frequency Division Multiple Access networks. The
proposed strategy is able to dynamically find spectrum assignments
per cell depending on the spatial distribution of the users
over the scenario, opening new spectrum access opportunities for
secondary spectrum usage. Reinforcement Learning methodology
has been employed to implement the strategy, which compared
with other fixed and dynamic spectrum assignment strategies
shows the best tradeoff between spectral efficiency and Qualityof-
Service while releases spectrum in large geographical areas.
