摘　　要：在协作多点(CoMP)蜂窝系统中,为了有效利用无线频谱资源,需要设计相应的分布式干扰协调机制。首先,利用相邻小区间接口交换信息的能力,设计了一种分布式的无线资源分配冲突检测与仲裁算法。接下来,针对协作多点蜂窝系统具体场景,应用所提出冲突仲裁算法,设计了包括三个步骤的分布式干扰协调方案。仿真结果表明,设计方案能够分布式地在协作多点蜂窝系统中的各区域间公平、自适应地分配无线资源,从而达到干扰协调的目的,并达到较好的无线资源空间复用效率。To efficiently utilize the radio spectrum resource in coordinated multi-point （CoMP） based cellular systems, the distributed interference coordination mechanisms are needed. First, based on the information exchange capability on the interfaces between neighboring cells, a distributed radio resource conflict detection and arbitration algorithm is proposed. Then, a distributed interference coordination scheme, which consists of three steps, is proposed. Simulation results show that the proposed scheme can fairly and adaptively allocates radio resource among regions in CoMP based cellular systems to achieve good resource spatial reuse efficiency.
