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

Key words: ultra-dense networks, noncooperation game, interference coordination, demand rate
