WCDMA user equipment is divided into four power classes. The maximum output
power of the UE transmitter depending on the power class is defined in 3GPP TS
25.101, section 6.2. An even lower "Maximum UE Power" value restricts the output
power range of the UE additionally.
Remote command:
UE Power Class
In signaling mode the UE power class to be used by the R&S
CMW can be set man-
ually or the UE power class reported by the UE in the capability report can be used. In
reduced signaling mode the UE power class must be set manually.
If no reported value is available, the manually configured value is used.
The power class influences the expected nominal power in automatic mode.
Remote command:
DPCCH Power Offset
Reference value for the initial DPCCH power of the UE at random access: The larger
the DPCCH Power Offset, the larger the initial DPCCH power.
If the dual carrier HSPA scenario is active, individual values can be set per carrier.
The DPCCH power offset for secondary uplink frequency is defined as the power offset
between the initial DPCCH power level on the secondary uplink frequency and the cur-
rent DPCCH power level on the primary uplink frequency.
Remote command:
Expected Initial DPCCH Power
Displays the expected power of the first DPCCH received from the UE. The value is
calculated as follows (see also 3GPP TS 25.331):
Expected power = Minimum(<Maximum UE Power>, <DPCCH Power Offset> – <Out-
put Power (Ior)> – <Level of P-CPICH>)

Remote command:
Uplink Scrambling Code
Number of the long code that the UE shall use to scramble the uplink WCDMA signal.
The scrambling code number must be in the range 0 to FFFFFF (hex) corresponding to
0 to 16777215 decimal.
