Latest progress for 3GPP ISAC channel modeling standardization

Currently, 3GPP TSG RAN1 has held four meetings focused on ISAC technology. These discussions have led to the approval of a common framework for ISAC channel modeling. At the same time, modeling schemes for target and background channels have been proposed. RCS modeling has also been considered, in particular the various factors affecting RCS values. These aspects will be the focus of future discussions as efforts continue to reach a consensus. In addition, further field measurements in typical scenarios are required to support the research and standardization of ISAC channel. Overall, ISAC channel modeling is a challenging and ongoing process.
