Default: 0

Enter a value for the frequency hopping offset of the PUSCHs.

Refer to the TS 3GPP 36.211 5.3.4 and 36.213 8.4 about the PUSCH frequency hopping for more information.  

Hopping Subbands

Range: 1 to 4

Default: 1

Double-click or use the drop-down menu to select the frequency hopping subbands.

This parameter is only available when the frequency hopping type is set to Type 2.

Refer to the TS 3GPP 36.211 5.3.4 and 36.213 8.4 for more information.
