K factor.
5.4.11.4 Scenario C1
The CDF percentiles of the K-factor in a suburban LOS environment are given in the Table 5.38.

The Ricean K-factor as a function of distance in a suburban LOS environment is shown in the Figure
5.61.
Figure 5.61: Ricean K-factoe as function of distance in a suburban environment.
The equation for the K-factor can be expressed as
where d is the distance between the BS and the MS.
5.4.11.5 Scenario D1
K = 17.1 – 0.0205 d (5.24)
The percentiles of the cumulative distribution function (CDF) of the Ricean K-factor at 100 MHz
bandwidth and 5.25 GHz centre-frequency in a rural LOS environment can be found in Table 5.39.
