This paper presents a thorough validation of the Third Generation Partnership
Project (3GPP) Technical Report (TR) 38.901 indoor hotspot (InH) path loss
model, as part of the 3GPP Release 19 study on “Channel model validation of TR
38.901 for 7-24 GHz,” for 6G standardization. Specifically, we validate the
3GPP TR 38.901 path loss model for the InH scenario in both line of sight (LOS)
and non line of sight (NLOS) channel conditions, using the floating intercept
(FI) and alpha-beta-gamma (ABG) path loss models. The validation focuses on
specific frequencies, including 6.75 GHz and 16.95 GHz, as well as the broader
7-24 GHz and 0.5-100 GHz frequency ranges. The validation is based on
real-world measurements conducted at 6.75 GHz, 16.95 GHz, 28 GHz, Und 73 GHz by
NYU WIRELESS using a 1 GHz wideband time domain based sliding correlation
channel sounder in the InH scenario for both LOS and NLOS channel conditions.
Our results confirm that the 3GPP TR 38.901 path loss model for the InH
scenario remains valid for the 7-24 GHz range in both LOS and NLOS conditions
and provide valuable input for 6G standardization efforts.
