A coordinated multi-point-based quality of service provision resource allocation scheme with inter-cell interference mitigation

The paper investigates resource allocation via power control for inter-cell interference (ICI) mitigation in an orthogonal frequency division multiple access-based cellular network. The proposed scheme is featured by a novel subcarrier assignment mechanism at a central controller for ICI, which is further incorporated with an intelligent power control scheme. We formulate the system optimization task into a constrained optimization problem for maximizing accepted users' requirements. To improve the computation efficiency, a fast yet effective heuristic approach is introduced for divide and conquer. Simulation results demonstrate that the proposed resource allocation scheme can significantly improve the network capacity compared with a common approach by frequency reuse.
