毫米波（mmWave）和太赫兹（THz）将用于第六代（6G）无线系统，特别是室内场景。本文提出了一种针对毫米波和亚太赫兹频率的室内三维 (3-D) 统计信道模型，该模型是根据 2014 年和 2019 年在办公楼中以 28 GHz 和 140 GHz 进行的广泛信道传播测量开发的。记录了超过 15,000 个功率延迟曲线 (PDP)，用于研究信道统计数据，例如时间集群数量、集群延迟和集群功率。信道生成过程中所需的所有参数均源自 28 GHz 和 140 GHz 视距 (LOS) 和非视距 (NLOS) 场景的经验测量数据。通过显示模拟均方根 (RMS) 延迟扩展和 RMS 角扩展与测量值产生良好的一致性，验证了信道模型。室内信道仿真软件建立在流行的 NYUSIM 室外信道模拟器的基础上，可以生成真实的信道脉冲响应、PDP 和功率角谱。
Millimeter-wave (mmWave) and Terahertz (THz) will be used in the sixth-generation (6G) wireless systems, especially for indoor scenarios. This paper presents an indoor three-dimensional (3-D) statistical channel model for mmWave and sub-THz frequencies, which is developed from extensive channel propagation measurements conducted in an office building at 28 GHz and 140 GHz in 2014 and 2019. Over 15,000 power delay profiles (PDPs) were recorded to study channel statistics such as the number of time clusters, cluster delays, and cluster powers. All the parameters required in the channel generation procedure are derived from empirical measurement data for 28 GHz and 140 GHz line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios. The channel model is validated by showing that the simulated root mean square (RMS) delay spread and RMS angular spread yield good agreements with measured values. An indoor channel simulation software is built upon the popular NYUSIM outdoor channel simulator, which can generate realistic channel impulse response, PDP, and power angular spectrum.
