For calls with constant data rates, the specified gain factors are valid for the entire
duration of the connection. For voice connections the UE can use DTX and switch off
the DPDCHs if no data is being transferred.
Use the CDP vs. Slot view of the WCDMA Multi Evaluation Measurement (option
R&S CMW-KM400) to verify to which degree of accuracy the actual gain factors of the
UL channels comply with the gain factors signaled to the UE.
Option R&S CMW-KS401 is required for HSDPA.
Remote command:
ΔACK, ΔNACK, ΔCQI
Power offset parameters Δ
ACK
, Δ
NACK
and Δ
CQI
for HS-DPCCH slots carrying ACK,
NACK and CQI messages.
Option R&S CMW-KS401 is required.
Remote command:
HSUPA
The following parameters control the gain factors for the uplink HSUPA channels E-
DPCCH and E-DPDCH.
The UE derives the gain factors from the signaled values. For details see 3GPP TS
25.213 section 4.2.1.3 and 3GPP TS 25.214 section 5.1.2.5B.
Option R&S CMW-KS401 is required.
ΔE-DPCCH ← HSUPA
Specifies the signaled value
Δ
E-DPCCH. The value is used by the UE to derive the
quantized amplitude ratio A
ec
. From this ratio it calculates the E-DPCCH gain factor
β
ec
.
Option R&S CMW-KS401 is required.
Remote command:
No of Reference E-TFCIs, Reference E-TFCI ← HSUPA
"No of Reference E-TFCIs" specifies how many pairs of reference E-TFCIs and
assigned power offset values are signaled to the UE. The pairs are taken from the
"Reference E-TFCI" table, using column 1 to n.
Each table column specifies a reference E-TFCI value and a signaled value
Δ
E-
DPDCH (power offset). The signaled
Δ
E-DPDCH values are used by the UE to derive
the quantized amplitude ratio A
ed
for each reference E-TFCI. From these ratios it calcu-
lates the reference gain factors
