Millimeter-wave (mmWave) and Terahertz
(THz) will be used in the sixth-generation (6G) wireless
systems, especially for indoor scenarios. This paper presents
an indoor three-dimensional (3-D) statistical channel model
for mmWave and sub-THz frequencies, which is developed
from extensive channel propagation measurements conducted in an office building at 28 GHz and 140 GHz in 2014
and 2019. Over 15,000 power delay profiles (PDPs) were
recorded to study channel statistics such as the number of
time clusters, cluster delays, and cluster powers. All the parameters required in the channel generation procedure are
derived from empirical measurement data for 28 GHz and
140 GHz line-of-sight (LOS) and non-line-of-sight (NLOS)
scenarios. The channel model is validated by showing that
the simulated root mean square (RMS) delay spread and
RMS angular spread yield good agreements with measured
values. An indoor channel simulation software is built upon
the popular NYUSIM outdoor channel simulator, which
can generate realistic channel impulse response, PDP, and
power angular spectrum.
