1. For scenario B3, XPR H values are not available. In the channel model implementation, these
values have been substituted by XPR V .
2. Distribution of XPR is log-normal, i.e., XPR = 10 X/10 , where X is Gaussian with standard
deviation σ and mean µ.
Average powers of the ZDSC are normalized so that the total power of all ZDSCs is equal to one. Then,
the normalized power of the nth ZDSC is

where Q is the number of ZDSCs. For the case when LOS model is used, the power of the direct
component is considered in the normalization such that the ratio of the direct power to the scattered power
is the K-factor.

It should be noted that when LOS component exists, the ZDSC will have 10+1 rays.
3.1.3 Directional distributions of ZDSCs
There are two types of angle information for each ZDSC. These are the mean angle and the offset angles
of each ray from the mean within each cluster. The zero mean azimuth departure (azimuth arrival) angle
is the transmitter (receiver) broadside direction. The generated mean angle of departures and angle of
arrivals are relative to the direct path between transmitter and receiver with respect to the broadside of
transmitter or receiver, respectively. The angle definitions and references that are used in the generic
channel model are the same as those presented in [3GPP SCM]. The relation between the mean azimuthdeparture
and the mean azimuth-arrival probability density functions of each ZDSC and their delays is
generated through correlated large-scale parameters used in the corresponding density functions. We
fixed the power azimuth spectrum of each ZDSC at the departure and the arrival sides assuming it as
Laplacian. The RMS angle-spread of each ZDSC is fixed to one value, which may be different in
departure from arrival and may vary from scenario to scenario. However, the power azimuth spectrum
(PAS) and the angle-spread values (AS ) of each ZDSC can be changed in the model if needed. The
distribution parameters of the mean angle of departure (AoD) and the mean angle of arrival (AoA) the
ZDSCs may vary from one scenario to another. The ZDSC azimuth-departure PAS and azimuth-arrival
PAS are defined by 10 rays having predefined offset angles for Laplacian PAS from the mean angles of
