Option R&S CMW-KS411 is required.
Remote command:
Unscheduled Subframes
Defines the transmission in the gaps between consecutive HS-SCCH subframes allo-
cated to the UE (inter-TTI distance > 1).
Option R&S CMW-KS411 is required.
●
Transmit Dummy UEID
: The HS-SCCH power is maintained and the unscheduled
HS-SCCH subframe contains the defined dummy UE ID, see
.
●
DTX
: Discontinuous transmission in unscheduled HS-SCCH subframes (output
power switched off)
Remote command:
Example for cyclic HS-SCCH selection (R5 connection)
Settings:
●
HS-SCCH #1: Level = –7 dB
●
HS-SCCH #2: Level = OFF
●
HS-SCCH #3: Level = –7 dB
●
HS-SCCH #4: Level = OFF
●
Selection = Cyclic/Automatic
●
Number of HSSCCH = 3
●
Inter TTI = 2 configured in HSDPA channel configuration, see
As a result of these settings, the HS-SCCH subframes 0 to 4 of the first two radio
frames are generated as follows:
●
Subframe 0: UE ID on HS-SCCH #1
●
Subframe 1: UE unscheduled due to Inter TTI = 2
●
Subframe 2: UE ID on HS-SCCH #2, but signal power off. UE returns DTX instead
of ACK or NACK.
●
Subframe 3: UE unscheduled
●
Subframe 4: UE ID on HS-SCCH #3
●
Subframe 0: UE unscheduled
●
Subframe 1: UE ID on HS-SCCH #1
●
Subframe 2: UE unscheduled
●
Subframe 3: UE ID on HS-SCCH #2, but signal power off. UE returns DTX instead
of ACK or NACK.
●
Subframe 4: UE unscheduled

HS-PDSCH Configuration
This section configures the HS-PDSCH.
For a dual carrier scenario, all settings are available per carrier. For switching between
the carriers see
