Meas. Power Offset Control, Meas. Power Offset
The measurement power offset
Γ
is signaled to the UE. The UE shall measure the P-
CPICH power and assume the total received HS-PDSCH power to be
P
HS-PDSCH
= P
P-CPICH
+
Γ
+
Δ
(CQI, UE Category)
The reference power adjustment
Δ
is only relevant for CQI channels and specified by
3GPP depending on the UE category.
In general, changing the measurement power offset will cause an offset of the CQI val-
ues reported by the UE. The larger the offset, the higher the reported CQIs.
For more details see 3GPP TS 25.214, section 6A.
Option R&S CMW-KS411 is required.
The first parameter can be set to the following values:
●
Manual
:
Γ
is set manually via the second parameter. A manual setting can be used
to report a wrong offset value to the UE and test its reaction, e.g. by analyzing the
returned CQI values.
●
Auto
: The correct value
Γ
is calculated automatically using the formula
Γ
= P
HS-PDSCH
- P
P-CPICH
-
Δ
(CQI, UE Category)
Remote command:
Unscheduled Subframes
Defines the transmission in the gaps between consecutive HS-DSCH subframes allo-
cated to the mobile (inter-TTI distance > 1).
Option R&S CMW-KS411 is required.
●
Dummy Data
: The HS-DSCH power is maintained as specified in 3GPP TS 34.121
for CQI reporting tests.
●
DTX
: Discontinuous transmission in unscheduled HS-DSCH subframes (output
power switched off)

HSUPA DL Channels
This section configures the downlink channels related to HSUPA: E-AGCH, E-HICH
and E-RGCH.
Channels transmitted via downlink carrier 1 control primary uplink carrier, channels
transmitted via downlink carrier 2 control secondary uplink carrier of the HSUPA con-
nection. For switching between the carriers see
Fig. 2-64: Physical channel DL settings - HSUPA
