4.2.12 ScalingFactorCCHPower

ScalingFactorCCHPower is a parameter for tuning the common controlchannel power for non-HSPA control channels. It can be configured byoperators, but has the following default value:

ScalingFactorCCHPower = 2

The parameter should be set per cell.

4.2.13 Z

Z is a parameter reflecting to what extent thermal noise contributes to the totalinterference. It can be configured by operators, but has the following defaultvalue:

Z = 2 [W]
