%X <span>Ultra-dense networks (UDNs) is a promising solution to meet the exponential increase in mobile data traffic. But&nbsp;</span><span>the ultra-dense deployment of cells inevitably brings complicated inter-cell interference ( ICI) and existing&nbsp;</span><span>interference coordination scheme cannot be directly applied. To minimize the aggregate interference of each small&nbsp;</span><span>cells, this paper formulates the problem as a distributed noncooperation game-based interference coordination&nbsp;</span><span>scheme in ultra-dense networks considering the real demand rate of each small cell user equipment (SUE) and&nbsp;</span><span>proves it to be a potential game. An improved no-regret learning algorithm is introduced to coverage to the Nash&nbsp;</span><span>equilibrium (NE) of the formulated game. Simulation results show that the proposed scheme has better performance&nbsp;</span><span>compared with existing schemes.</span>
