摘　　要：为了解决LTE宏微协同组网中的干扰问题,提升网络协同性能,研究了eICIC、FeICIC、CoMP、小区合并等宏微协同干扰抑制技术。首先分析了各类干扰抑制技术的原理,然后从性能特点、部署条件、发展进程等角度出发并结合宏微协同的典型场景给出了技术应用建议。提出了宏微协同组网应优先采用宏微共基带的方式,优先采用CoMP技术来抑制干扰,同时干扰抑制技术的应用需要分阶段、逐步地推进,并与LTE网络的发展相同步。In order to deal with interference in LTE macro-micro cell coordinative networking and improve coordinative performance of network, several interference suppression techniques including e ICIC, Fe ICIC, Co MP and cell combination were discussed in this paper. Firstly, principles of these interference suppression techniques were analyzed. Then, from aspects of performance characteristics, deployment conditions and development processes, application recommendations of these techniques were presented according to typical scenarios of macro-micro coordination. It was suggested that macro-micro baseband pool should be adopted in macro-micro coordinative networking. CoM P technique was preferentially used to suppress interference. In addition, the application of inter-ference suppression techniques should be propelled gradually and synchronized with the development of LTE net-work.
