[srslte-users] Downlink data rate dropping to half at MCS = 28

[Bilal Maqsood]

Hi All,

I am trying to test the max downlink data rate. However, I am facing a
strange issue as I fix the downlink MCS to 28, the DL data rate reduced to
half of what I got for MCS 27.

At MCS 27 DL data rate = 62 Mbps
and
At MCS 28 DL data rate = 35 Mbps

Please let me know if anybody has faced this problem.
I am using iperf3.

Thanks and regards
Bilal
