title = "A sum-rate maximization scheme for ultra-dense network",
abstract = "This paper considers the power allocation to maximize the sum-rate of the users when the total allocated power is limited in the ultra-dense network (UDN). In the paper, we first regard the interference caused by the specified base station (BS) to the other mobile station (MS) as a constant, and obtain the expression of the allocated power of each BS. However, it is not a closed-form solution, we apply the classic water-filling algorithm to get the optimum power allocation by some times of iterations. Finally, the simulation results show that the power allocation scheme can greatly improve the sum-rate of the users compared to the average power allocation.",
