摘　　要：小基站已成为运营商为用户提供更高数据业务速率和容量的重要技术手段,但随着小基站部署密度的增大,会导致很多问题的出现,如频繁的切换失败,回程链路的非理想化等等。通过进一步研究小基站的增强技术,可以更好地改善这种多层混合组网的整体性能。为解决这些问题,文章针对不同场景进行了增益分析,并给出了潜在解决方案,最后通过分析对比,找到比较合适的小基站增强技术。Small Cell has become an important teehnology to improve user data rate and system eapacity; but with inerease of density of Small Cell deploytment, a lot of issues have occurred, such as frequent handover failure, non-ideal baekhaul etC. Apparently if these issues can be solved well, the overall performance for network with multiple layers deployment will be further improved. In this paper, evaluation in various scenarios are provided, accordingly a solutioni （i.e. Dual connectivity） is put forward. Finally by comparison of different architecture options, we can find a more suitable small cell enchaneement tecnique.
