Abstract
Ultra-dense network (UDN) downlink interference is researched in this paper, where some neighboring base stations significantly interfere with objective user. This problem arises from increasing node deployment density in UDN. And serious interference generates from neighboring inter-cell. With respect to this problem, a novel clustering priority-based user-centric interference coordination scheme (CPUCIC) is presented, where performance gain can be attained with base station cooperation and interference nulling. Simulation results demonstrate that the proposed scheme can increase two following performance, signal interference plus noise ratio (SINR) and user bandwidth gain-to-loss ratio. However, system performance with CPUCIC scheme is increased at the cost of bandwidth.
