Tutorial: Recent Progress on Channel Measurement and Modeling for 6G Part 2

This tutorial focused on the recent progress in channel measurement and modeling for 6G, including four aspects: 1. Channel measurements and modeling of multi-bands from centimeter to millimeter wave: The propagation mechanisms vary along the frequency domain. We will give a review of the channel measurement, the propagation mechanism modeling, and the channel modeling approach in sub-6GHz, new mid-band, mmWave, and THz bands. 2. Massive MIMO channel measurements and modeling: The spatial non-stationary near-field channel model for massive MIMO is reviewed. As a multi-antenna technology, reconfigurable intelligent surface (RIS) is discussed and the RIS-assisted channel model is reviewed. 3. ISAC channel measurements and modeling research: We will present a channel measurement campaign for the JCAS channel and introduce a stochastic JCAS channel model that can jointly generate communication and sensing channels. 4. Intelligent channel modeling and channel prediction research: Improving the accuracy and reducing the complexity is of critical importance for channel modeling. Various AI methods can be utilized to improve training efficiency and reduce prediction errors. The tutorial will give an introduction to the AI-based channel model and prediction method. In addition, background and challenges, channel sounding methodologies, and future research directions on channel measurement and modeling for 6G are introduced successively in detail.
