Query: Load-aware Dynamic Spectrum Access for Small Cell Networks: A Graphical
  Game Approach   In this letter, we investigate the problem of dynamic spectrum access for
small cell networks, using a graphical game approach. Compared with existing
studies, we take the features of different cell loads and local interference
relationship into account. It is proved that the formulated spectrum access
game is an exact potential game with the aggregate interference level as the
potential function, and Nash equilibrium (NE) of the game corresponds to the
global or local optima of the original optimization problem. A lower bound of
the achievable aggregate interference level is rigorously derived. Finally, we
propose an autonomous best response learning algorithm to converge towards its
NE. It is shown that the proposed game-theoretic solution converges rapidly and
its achievable performance is close to the optimum solution.
