工业物联网、大型商超、体育场馆等室内通信场景的重要性在6G无线通信系统中日益显著。研究室内视距（LoS）信号概率模型有利于提升室内通信系统性能分析准确性。针对室内环境，考虑家具、设备等室内阻挡物的任意位置以及任意高度，构建了视距信号概率模型。该模型可以准确刻画不同阻挡物场景下的视距概率。基于视距信号概率模型，推导了信噪比分布，并研究了室内覆盖性能和能量效率。相关研究成果有助于指导室内无线通信系统部署，降低成本。
Abstract：The importance of indoor communication scenarios, such as industrial Internet of things, superstores, and stadiums, is becoming increasingly significant in the sixth generation(6G) wireless communication systems. The investigation into indoor line-of-sight(LoS) signal probability is conducive to improving the accuracy of indoor communication performance analysis. In this paper, a LoS probability model is constructed for indoor environments, considering any position and any height of blockages. This model can accurately characterize the LoS probability in different scenarios. Based on the model, this paper derives the signal-to-noise ratio(SNR) distribution and investigates the coverage performance and energy efficiency. The research results are instrumental in instructing the deployment of indoor wireless systems and reducing costs.
