If the secondary scrambling code is deactivated, the primary scrambling code is used.
Remote command:
Phase ← S-CPICH Enhanced
Defines the phase of the S-CPICH in degrees, relative to the P-CPICH phase. Within
the allowed range, you can set multiples of -45 degrees.
Remote command:
AICH Enhanced
The following enhanced settings apply to AICH.
Transmission Timing ← AICH Enhanced
Defines the minimum allowed time delay between two consecutive RACH preambles.
RACH preambles are sent by the UE during a random access procedure.
Remote command:
Acknowledge ← AICH Enhanced
Defines how the R&S
CMW acknowledges RACH preambles received from the UE.
●
Positive
: Normal operation mode. The R&S
CMW acknowledges or negatively
acknowledges the preambles appropriately. The UE can be registered and a con-
nection can be set up.
●
Negative
: The R&S
CMW always responds with negative acknowledgments so
that the random access procedure fails after the maximum number of preamble
cycles has been reached. The UE will reinitiate a new preamble cycle after a while
but not succeed in performing a registration or establishing a connection.
This setting can be used for repeated tests of the random access procedures.
Remote command:
DPCH Enhanced
The following enhanced settings apply to DPCH.
2nd Scrambling Code ← DPCH Enhanced
Defines index k used for calculation of a secondary scrambling code number by adding
k to the value of parameter
If the secondary scrambling code is deactivated, the primary scrambling code is used.
Remote command:
Power Offset ← DPCH Enhanced
Defines the power of the DPCCH relative to the power of the DPDCH. The DPDCH
power is defined as "DPCH" level in the channel table.
