A novel concept, the neighbourhood small cell (NSC) network, has been brought up to provide high-capacity wireless communications in a cost-effective manner. The indoor small cells not only cover indoor users but are also considered open access to serve outdoor users through indoor to outdoor (I2O) propagations. In this correspondence, we facilitate the analytical performance evaluation for a pure NSC network system by deriving the distribution of the signal to interference ratio (SIR) and the outage probability in closed-form expressions. In the proposed system evaluation scheme, both the indoor penetration loss and the Nakagami-$m$ fading are taken into account. Numerical results obtained in a typical urban scenario show that the system performance of a pure NSC network depends on the propagation environment, the indoor building structures and the layout of the neighbourhood significantly.

使用邻域小基站进行室内到室外通信的评估

提出了一种新颖的概念，即邻域小小区 (NSC) 网络，以经济高效的方式提供高容量无线通信。室内小基站不仅覆盖室内用户，还被视为开放接入，通过室内到室外 (I2O) 传播为室外用户提供服务。在此对应关系中，我们通过推导信号干扰比 (SIR) 的分布和封闭式表达式中的中断概率来促进对纯 NSC 网络系统的分析性能评估。在提出的系统评估方案中，室内穿透损耗和 Nakagami-$m$ 衰落都被考虑在内。在典型城市场景下获得的数值结果表明，纯 NSC 网络的系统性能取决于传播环境，
