The relative level setting specified in dB describes the relationship between the OCNS
channels. The total power level of all OCNS channels depends on the power level of
the other channels, see
chapter 6.2.5, "Power Levels" , on page 918.
6.2.5 Power Levels
The individual channel power levels and the OCNS power level are expressed relative
to the RMS output power of the generator. The total power of all active channels
(excluding OCNS channels) is called "accumulated power". It is calculated under con-
sideration of the transmission duration of each channel within a timeslot or frame (see
chapter 6.2.2, "Channel Structure" , on page 908):
●
SCH: first 256 chips of a slot (2560 chips)
●
P-CCPCH: last 2304 chips of a slot (2560 chips)
●
PICH: 288 bits of a frame (300 bits)
●
F-DPCH: 256 chips of a slot (2560 chips)
●
all other channels: transmitted during entire timeslot / frame
Example: For a configuration with active P-CPICH, DPCH, PICH, P-SCH and P-
CCPCH the accumulated power is calculated according to the following formula:
