For HSPA tests (R6) the OCNS uses only channelization code 6 (SF = 128).

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 2.2.10.6, "Power Levels" , on page 41.
2.2.10.6 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 is
called "accumulated power" (including OCNS channels and excluding AICH and S-
CCPCH that are not active during the actual call). It is calculated under consideration
of the transmission duration of each channel within a timeslot or frame.
The transmission durations are as follows:
●
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)
●
AICH: 4096 chips out of 5120 chips (not relevant for accumulated power)
●
All other channels: transmitted during entire timeslot / frame
For HS-SCCH, HS-DSCH, E-AGCH, E-RGCH and E-HICH it is assumed that these
channels are transmitted continuously, e.g. unscheduled subframes/slots filled with
dummy data.
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:
