Abstract: The proposed tutorial is intended to offer a comprehensive and in-depth course to communication professionals/academics, aiming to address recent advances and future challenges on channel measurements and models for sixth generation (6G) wireless communication systems. The 6G vision and paradigm shifts are summarized as global coverage, all spectra, full applications, all senses, all digitals, and strong security, which would bring new performance metrics and requirements. To meet these requirements, 6G networks will rely on novel key technologies, i.e., air interface and transmission technologies and network architecture. The underlying 6G wireless channels will face new channel characteristics, such as space-timefrequency non-stationarities, which need to be thoroughly studied. Channel measurements and non-predictive channel models are then reviewed for challenging 6G scenarios and frequency bands, focusing on millimeter wave (mmWave), terahertz (THz), and optical wireless communication channels under all spectra, satellite, unmanned aerial vehicle (UAV), and maritime communication channels under global coverage scenarios, and high-speed train (HST), vehicle-to-vehicle (V2V), ultra-massive multiple-input multiple-output (MIMO), reconfigurable intelligent surface (RIS), industry Internet of things (IoT), and orbital angular momentum (OAM) communication channels under full application scenarios. New machine learning based predictive channel models will also be investigated. A non-predictive 6G pervasive channel model will then be proposed, which is expected to serve as a baseline for future standardized 6G channel models. Future research challenges and trends for 6G channel measurements and models will be discussed in the end of the tutorial.
