中文摘要：

在密集小蜂窝网络场景下，针对同层干扰和跨层干扰问题，提出了一种联合增强型小区间干扰协调和协作多点联合传输的密集小蜂窝干扰管理机制．这种机制考虑了协作多点联合传输对用户的链接、几乎空白子帧的配置、资源块分配的影响，在保证用户最低速率的前提下，最大化系统的吞吐量．仿真结果表明，相比基于增强型小区间干扰协调的干扰管理方法，联合增强型小区间干扰协调和协作多点联合传输的干扰管理方法进一步提升了网络吞吐量，提高了频谱利用率．

英文摘要：

This paper considers the cross-layer and co-layer interference in small cell networks. Wepropose an interference management scheme by jointly optimizing user association, ABS （Almost Blank Subframes） configuration, and resource allocation. Especially, the proposed interference management smartly utilizes the opportunities of CoMP-JT （Coordinated Multi Point-Joint Transmission） to mitigate the interference from the macro base station to increase the coverage area of small cells. Simulation results show that the proposed interference management improves network throughput and spectrum efficiency as compared with the existing methods.
