Measurement Campaigns, Datasets, and Curve Fitting Officially Used by 3GPP in the Release 19 for Channel Modeling in TR 38.901 for 7-24 GHz

2026-03-26

AI Summary

This work addresses the absence of a 3GPP-adopted standardized channel model and corresponding measurement data for the 7–24 GHz frequency band. To bridge this gap, the study systematically conducts millimeter-wave channel measurements and constructs a large-scale, wideband measurement dataset spanning the entire 7–24 GHz range. Channel parameters are extracted and modeled in strict compliance with the 3GPP TR 38.901 framework, followed by rigorous curve fitting. The resulting dataset and modeling methodology constitute the foundational channel model officially adopted by 3GPP Release 19, marking the first public release of such standardized data and procedures for this frequency range. This contribution provides authoritative support for the design of 5G-Advanced and 6G high-frequency communication systems and advances the standardization and unification of millimeter-wave channel modeling.
