E-RGCH
Configures E-RGCH related parameters.
Sequence Index ← E-RGCH
Defines the index of the E-RGCH signature sequence used to separate the E-RGCH
channel from the E-HICH. The value corresponds to the sequence index l defined in
3GPP TS 25.211.
To generate a signal conform to 3GPP select identical channelization codes but differ-
ent sequence indices for E-HICH and E-RGCH. For configuration of channelization
codes see
chapter 6.3.3, "Physical Channel Settings" , on page 931.

Mode / Pattern ← E-RGCH
Define a relative grant sequence to be transmitted via the E-RGCH to the UE.
The parameter Mode selects the type of the sequence: sequence filled with one bit (All
Up, All Down, All Hold), alternating sequence or freely selectable pattern (User Pat-
tern).
The parameter Pattern allows to define an arbitrary sequence that is used if "User Pat-
tern" is selected. The following characters are supported: 1 (= Up), 0 (= Hold), – (=
Down). To enter a Down via the front panel keys press the colon button.
