摘　　要：本文以业务特征为着眼点,设计了两种适用于超密集网络的干扰协调技术——大规模CoMP(协作多点传输)、ON/OFF(动态小区开关)机制。通过对3种典型业务的分析与建模,并基于3种业务对两种干扰协调技术进行仿真,仿真结果表明在特定的业务模型下,两种干扰协调技术均能有效地降低系统干扰,提升系统性能。This paper focused on thecharacteristic of traffi c model, designed two kinds of interference coordination technology apply to ultra dense network--large scale CoMP and dynamic cell ON/OFF algorithm. Through the analysis and modeling of three kinds of typical traffi c model, the simulations are fulfi lled on two types of interference coordination technology based on four kinds of traffi c models. The simulation results validate that both interference coordination technologies can decrease the inter-cell interference, promote system performance with the specifi c traffi c model.
