Enable (Carrier 2)
Enables or disables the usage of the second carrier for data transport via the HS-
DSCH.
This parameter is only visible while the dual carrier scenario is active.
Options R&S CMW-KS404 and R&S CMW-KS411 required.
Remote command:
Inter TTI Distance
Minimum distance between two consecutive transmission time intervals in which the
HS-DSCH is allocated to the UE.
If the dual carrier scenario is active, you can configure the parameter per carrier.
Option R&S CMW-KS411 required.
Remote command:
Number of HARQ Processes
Number of hybrid automatic repeat request processes for retransmission of HSDPA
packets.
Option R&S CMW-KS411 required.
Remote command:
IR Buffer Size
Displays the size (no. of bits) of the virtual IR buffer used in the H-ARQ process. The
IR buffer size is given by the total buffer size divided by the number of HARQ pro-
cesses. The total buffer size for all H-ARQ processes is fixed for each UE category;
see 3GPP TS 25.306, table 5.1a, "Total number of soft channel bits".
Option R&S CMW-KS411 required.
Remote command:
Transport Block Size Index
Value of the Transport Format and Resource Indicator (TFRI) signaled to the UE. The
TFRI is also called k
i
in the specification. It is used for calculation of the transport block
size.
If the dual carrier scenario is active, you can configure the parameter per carrier.
Option R&S CMW-KS411 required.
Remote command:
Transport Block Size
Displays the used transport block size for information. The value depends on the trans-
port block size index, the modulation type and the number of assigned channelization
codes.
