Decoded Info (5G NR/5G-Advanced)

There are two types of traces in the Trace > Data > Demod and MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. menus that display component carrier data: CCn (component carrier is fixed), and Selected Display CC (component carrier is dynamically selected using the Display parameter). See About Per-Carrier Trace Types for more information.

Decoded Info displays the decoded information results for the physical channels with decoding enabled.

DecodedBits - Decoded bits by PeriodIndex, BlockIndex and SymbolIndex. If there are more than 100 decoded bits, the decoded bit data will not be displayed in Decoded Info trace. See the Decoded Symbols trace to view decoded data longer than 100 bits.
CRC Cyclic Redundancy Check - Pass/Fail CRC results by PeriodIndex, BlockIndex and SymbolIndex.

PDSCH Decoder

Allocation Info - Frequency domain and time domain allocation information:

PDSCH Physical Downlink Shared Channel Index
CarrierIndex
BWPIndex

Primary Decoded Info:

SlotIndex - Index of the decoded slot as configured in the selected PDSCH's Allocated Slots parameter.
RV Redundancy Version Index - RV Index as specified in the selected PDSCH's RV Index parameter.
EffectiveCodeRate - Effective code rate. The effective code rate should be close to the Target Code Rate displayed in the selected PDSCH's Demod Properties.
CRC - Pass/Fail CRC results by Codeword and SlotIndex.

Additional Info:

Codeword
Number Of Code Blocks
Failed Code Blocks (when PDSCH Auto Detection is selected)
Number Of Corrected Bits - Number of bits corrected by the error correcting algorithm resulting CRC pass.

PUCCH Decoder

Allocation Info - Frequency domain and time domain allocation information:

PUCCH Index
CarrierIndex
BWPIndex

Primary Decoded Info:

SlotIndex - Index of the decoded slot as configured in the selected PUCCH's Allocated Slots parameter.
DecodedBits - Decoded bits by SlotIndex. If there are more than 100 decoded bits, the decoded bit data will not be displayed in Decoded Info trace. See the Decoded Symbols trace to view decoded data longer than 100 bits.
CRC - Pass/Fail CRC results by SlotIndex.

For PUCCH Format 0, decoded bits is provided but it requires the user to provide the payload size information. The CRC is not returned because there is no CRC attached to PUCCH Format 0, so the display shows CRC=***.

For PUCCH Formats 1, 2, 3 and 4, when the UCI bit size (PUCCH bit number) is less than 12 bits, there is no CRC result, and the decoded bits are displayed in the Decoded Symbols trace.

Primary Decoded Info:

SlotIndex - Index of the decoded slot as configured in the selected PUSCH's Allocated Slots parameter.
RV Index - RV Index as specified in the selected PUSCH's RV Index parameter.
EffectiveCodeRate - Effective code rate. The effective code rate should be close to the Target Code Rate displayed in the selected PUSCH's Demod Properties.
CRC - Pass/Fail CRC results by Codeword and SlotIndex.
