The power allocated to control
channels may depend on equipment vendor recommendation. Typically no more than 20% of the total NodeB
power is allocated to control channels, including CPICH. However, if HSDPA is deployed on the same
carrier then the total power allocated to control channel may go up to 25 to
30% because of the additional HSDPA control channels required.

What is a typical EiRP?
The EiRP depends NodeB transmit
power, cable and connector loss and antenna gain. With a sample system of 43dBm transmit power,
a 3dB cable and connector loss and a 17dBi antenna gain, the EiRP = 43 – 3 + 17
= 57dBm.
