In peak test scenarios, DMRS SINR must be greater than 30 dB. This ensures that the MCS index is 27 and the IBLER is close to 0%.
Is it possible IBLER should be 0%?
IBLER is always 10%…
This is how MCS is decided based on cqi and BLER.
Only residual BLER is 0%
So phrases in powerpoints are hilarious.
There are up to 6 harq retransmissions for each packet so plenty of chances to get residual bler to 0%.
This is for 5G.
We know that: BLER = No of ACK Codeword / ( ACK + NACK) *100%.
But I mean, how long UE sum of CW?
UE and eNB/gNB both calculate BLER, their value may be different?
