PHICH Transmission Configuration (Advanced LTE FDD Downlink)

State

Choice: On | Off  

Default: Off

Check (On) or clear (Off) to set the channel state.

Sequence Index

Range:

0 to 7 (Normal Cyclic Prefix)

0 to 3 (Extended Cyclic Prefix)

The software assigns a Sequence Index number to each available sequence in the Group.

PHICH Transmission Configuration is showing PHICH Sequence Index in the PHICH group. The relationship between Sequence Index and orthogonal sequence is shown in the table below:

Couple

Choice: On | Off  

Default: On

Check (On) or clear (Off) to set the coupling state.

When Couple is turned on, the configuration for Subframe 0 is applied to all subframes in the sequence.

To configure each subframe in a sequence individually, turn Couple off.

Subframe#nHI

Use the ClosedData Source Selection dialog box to select ACK, NACK,or DTX for the selected subframe.

ACK = positive acknowledgement for the selected subframe.

NACK = negative acknowledgement for the selected subframe.

DTX = discontinuous transmission for the selected subframe.
