Hello,
we have tried both settings (CQI Adjustment by IBLER & by Dynamic BLER) we got a good improvement in the NACK Rate & RLC Throughput after applying the CQI Adjustment by IBLER Value with setting the IBLER Target Value to 10% (This is the value recommended by Qualcomm). However we didn't see any improvement when we tried the CQI Adjustment by Dynamic BLER. we saw a degradation in the NACK Rate after applying it with no improvement in the throughput.
