Wireless MIMO Channel Modeling for B5G Indoor Scenarios

Indoor communication has been widely concerned by both academia and industry. Wireless channel characterization is the basis for communication system deployment. Wireless channel characterization in indoor office scenarios and indoor factory environments is equally necessary but more challenging than channel characterization in typical outdoor communication environments. In this paper, we summarize the existing indoor MIMO channel models, describe the characteristics of different indoor scenarios such as office and factory environments. Then the characteristics of indoor channel models for FR3 are analyzed. Furthermore, we consider indoor channel modeling for ISAC, and describe the characteristics of different indoor scenarios such as office and factory environments. The research in the paper can enrich indoor channel investigations and enable the design and practical deployment of indoor communication systems.
