Hi Experts,
MCS 16&17 both are mapped to TBS index 15.
What is the difference in scheduling between MCS 16 & MCS 17?

Modulation order.

MCS is different 16QAM and 64QAM as you can seee carry bit are 4 and 6, right?

Yes I see. But same TBS.

Probably coding scheme is different too between MCS 16 & 17.

Hainm · July 4, 2021, 12:36am

So MCS 16 & 17 code rate is much different.

Looks like 16QAM on MCS16 & 64QAM on MCS17.

Mod order and code rate are different

Code rate = (TBS + CRC) / ( number of REs * Mod Order)
