The coupling loss (CL) is the effective path loss (Section 7.6.1) and is proportional to the cell size. Figure 446 451 illustrates an OFDMA UL for a single cell:

For one event, SEAMCAT calculates the CL for all the active UEs which are uniformly distributed over cells and the network. SEAMCAT gathers all the CL value and generate a CDF of it. The CL_xile value is taken out of this CDF for a certain percentile (xile = “power scaling threshold”) and then fed into the equation. The power scaling threshold can be interpreted as the percentage of UEs Transmitting with less than the maximum power.
Figure 447 452 illustrates the CDF of the CL and the meaning of the X-ile with some illustrative numbers.
