nr_dlsim, coding table 2 (256QAM) and mcs 27
nr_dlsim "-n100" "-q1" "-e27" "-s30"
is in the CI
the result is "ok" for a long while, but, even with perfect signal (no channel noise) these are retransmissions
Another change made it worse:
NR_DMRS_DownlinkConfig__dmrs_AdditionalPosition_pos1 instead of NR_DMRS_DownlinkConfig__dmrs_AdditionalPosition_pos0
with this dmrs configuration, the retransmissions grow from 1.2 retransmissions (so 1/5 packets resent) to 1.7 therefore the test is now "nok"
but there is a bug, likely in nr_dlsim or in the OAI UE because it seems not occuring with commercial UE
