Abstract: Abstract This paper investigates an anti-interference energy-efficient power allocation scheme in the multi-carrier millimeter-wave (mmWave) ultra-dense networks. To suppress the severe intercell-interference, this work proposes a novel interference minimization scheme based on the non-cooperative game theory for energy-efficiency maximization. In each best response, the non-convex problem is transformed into some convex subproblems, and each is solved by a low-complexity stair water-filling (SWF) algorithm over some subintervals. The interference minimization scheme, together with the SWF algorithm, has been proven to converge to a unique Nash equilibrium point. Simulation results and numerical analysis show that the scheme displays significant energy-efficiency performance advantages over other iterative water-filling methods.
