摘要
Abstract
Device-to-Device communications in cellular networks can improve the performance of the cellular system,while bringing a lot of interference.In order to alleviate the interference from cellular networks to D2D,this paper introduces a resource allocation algorithm for cross-cell D2D based on virtual sectors.First of all,the interference limited area is proposed so that cellular resources can not be located within the limited area.Secondly,in order to establish large spatial distances between users that are supposed to share the same set of radio resources,the concept of virtual sectors is presented.Finally, with the purpose of maximizing the throughput of the system,the base station selects the best channel quality of k cellular subscribers,after that,the resources of the k cellular subscribers are assigned to D2D users.The simulation results prove that the proposed algorithm can effectively reduce interference from cellular networks to D2D,improve the throughput of the sys-tem and the system performance.关键词
