本研究旨在分析嵌入热点的分层蜂窝结构，该结构位于WCDMA宏蜂窝系统中，重点关注在此场景下引入智能天线的影响。采用系统级仿真方法，考虑两种解决热点业务的主要方案：部署微蜂窝天线或在宏蜂窝处采用智能天线技术，随后评估信号干扰比（SIR）的相对增益。根据不同业务类别的用户比例定义不同场景，进而评估每种场景下最适合的方案。
英文摘要
The purpose of this contribution is to analyze a hierarchical cell structure with a hot spot embedded in a WCDMA macrocellular system. Particular attention is paid to the impact of introducing smart antennas in this context. A system-level simulation approach is employed, in which we consider two main solutions to address hot-spot traffic: the placement of a microcell antenna or the adoption of smart antenna technology at the macrocell. Relative gains in signal-to-interference ratio (SIR) are then evaluated. Distinct scenarios are defined based on the proportion of users of different service classes. An evaluation of which solution is best suited to each scenario is then conducted.
