PUCCH Bits (LTE-Advanced)

PUCCH Bits specifies how much coding to undo before showing the bits from PUCCH Physical Uplink Control Channel on the Decoded Symbol Table. See 3GPP TS Technical Specification 36.212, Section 5.2.3 for a diagram of the coding operations performed on PUCCH.

The following is a list of the available PUCCH Bits selections and the resulting bits.

Mapped - raw PUCCH bits are mapped to resource element locations and shown in the Symbol Table. No PUCCH bits are shown in the Decoded Symbol Table.
Descrambled - descrambled (channel coded) bits for each subframe are shown on the Decoded Symbol Table.
Decoded - decoded bits for each subframe are shown in the Decoded Symbol Table.

For PUCCH Format 2/2a/2b, where both CQI Channel Quality Indicator / PMI Precoding Matrix Indicator and HARQ Hybrid Automatic Repeat Request-ACK Acknowledgement bits are jointly encoded, CQI / PMI information bits are listed first in a set of PUCCH bits, followed by HARQ-ACK information bits.
