摘　　要：为了保证(LTE-Advanced)异构网络控制信道的可靠传输,首先对异构组网后的典型干扰场景进行了详细的分析;然后,针对上述干扰情况提出了2种可行的控制信道干扰协调方案;最后,通过对异构网络进行系统级的仿真建模来评估这2种控制信道干扰协调技术对系统性能的影响。仿真结果表明,提出的控制信道干扰协调技术能够有效提升异构网络系统的整体性能。In order to ensure the reliable transmission for control channel in LTE-Advanced with heterogeneous networks, this paper firstly makes a detailed analysis on the interference scene in heterogeneous networks. Then, two possible interference coordination technologies for control channel are proposed. Finally, we evaluate the two interference coordination technologies on system performance by system-level simulation model. The simulation results show that the proposed technologies can effectively improve system performance of heterogeneous network.
