B.1.3. Error Free Setting
For the UE to receive DL-SCH with high TBS, the CFI must be made smaller. As a result, the Symbol count used in
PDSCH increases and since the number of Physical Channel bits becomes larger, the Code Rate increases.
Consequently decoding is possible even when the MCS Index is high.
Common Parameter - CFI Setting
(Example at 20 MHz: The CFI setting range varies with the Channel Bandwidth. Refer to the MX88201xC LTE
Measurement Software operation manual.)
Code Rate
By making the CFI smaller, the Symbol count used in PDSCH increases and since the number of Physical Channel
bits increases, the Code Rate increases and the UE can decode DL-SCH even when the MCS Index is high and the
Code Rate exceeds 0.930.
However, care is required when making settings in the small region, because the Code Rate may rise above 0.930
where sufficient Physical Channel Bits cannot be secured.
