Fill-Up Frame With Dummies
With a 10 ms TTI the E-RGCH and E-HICH are transmitted for 12 slots per frame. Dur-
ing the remaining slots it is possible to switch the channels off (DTX) or to continue
sending in order to maintain the channel power (fill-up with dummies). This setting has
no effect for 2 ms TTIs.
If the dual carrier HSPA scenario is active, individual values can be set per carrier.
Option R&S CMW-KS401 is required.
Remote command:
HARQ Feedback (E-HICH)
The following parameters configure the HARQ feedback transmitted via the E-HICH.
If the dual carrier HSPA scenario is active, individual values can be set per carrier.
Option R&S CMW-KS401 is required.
Option R&S CMW-KS405 is additionally required for dual carrier HSPA.
Mode ← HARQ Feedback (E-HICH)
Type of the HARQ acknowledgment indicator sequence transmitted via the E-HICH.
You can e.g. send an alternating sequence or an all ACK or all NACK sequence. ACK
corresponds to 1, NACK to 0.
The selection "React on UL CRC" sends: ACK for correct UL CRC, NACK for UL CRC
error, DTX if no E-DPCCH is detected.
Remote command:
Signature ← HARQ Feedback (E-HICH)
E-HICH signature used to separate the E-HICH from the E-RGCH and from the E-
HICH/E-RGCH allocated to other UEs.
The value is equal to the "Sequence index l" defined in 3GPP TS 25.211. Configure
different values for the E-HICH signature and the E-RGCH signature.
Remote command:
Relative Grant (E-RGCH)
The following parameters configure the relative grant sequence transmitted via the E-
RGCH.
If the dual carrier HSPA scenario is active, individual values can be set per carrier.
Option R&S CMW-KS401 is required.
Option R&S CMW-KS405 is additionally required for dual carrier HSPA.
