Reply To: Low MCS usage



could you check your retransmission rate in DL ?
I think it is available per MCS, isn’t it ?
Basically, you may want to check your DL quality (BER). The voice is not a good indication on BER because it is very resistant (C/I around 9dB is ok). MCS9 on the other is very sensitive and requires a C/I around 30dB !
