CPICH pwer is set 10% for total power, that is if total power=20W(43dBm) then CPICH=2W(33dBm)
Can anybody help
1. how to Calculate power for control channels and signalling channels from CPICH power
2. Power remaining for users.
Thanks,

here is the table for reference:
Power (dBm) Power (Watts)
Max TX Power 43 19.95
Pilot Power 33 2.00 10%
PCCPCH 29.9 0.98 -3.1 db
SCCPCH 32.6 1.82 -.4 db
PSCH 31.2 1.32 -1.8 db
SSCH 29.5 0.89 -3.5 db
Total Pilot and Control Channel Power 38.45 7.00 35.09%
Available Traffic Power 41.12 12.95 64.91%
