中文摘要：

为抑制小区间干扰，提高系统性能，研究了异构网络中的基站分簇问题，提出了一种基于阈值的协作基站分簇方法。该方法在异构组网场景下，以最大化接收端传输速率为目标，通过选择满足设定阈值的基站进行协作，考虑了用户所属基站信号强度和非所属基站的干扰情况，分析了不同分簇方法下的用户传输速率变化情况。仿真结果表明，所提算法在系统传输速率性能方面优于现有方法。

英文摘要：

The base station clustering problems in wireless heterogeneous network to suppress the inter cell interference were studied. A clustering method based on the threshold, which can improve the system performance, was proposed. The method maximizes the transmission rate for the target under the heterogeneous network scenarios, then selecting the base stations meeting the threshold value to collaborate, at the same time considering the user belonging-base station＇s signal intensity and the no-belongings＇ interference. The receiver transmission rate in different clustering methods was analyzed. The simulation results show that the proposed method is better than the existing methods in the system transmission rate.
