I am running 802.11 simulations in NetSim and want to understand how the data rate is determined for different MCS in 802.11.
Thank you.

With the knowledge of MCS index and bandwidth of the channel data rate is set in the following manner
1: Gets the number subcarriers that are usable for the given bandwidth of the medium.
2: Gets the Number of Bits per Sub Carrier (NBPSC) from selected MCS
3: Number of Coded Bits Per Symbol (NCBPS) = NBPSC*Number of Subcarriers
4: Number of Data Bits Per Symbol (NDBPS) = NCBPS*Coding Rate
5: Physical level Data Rate = NDBPS/Symbol Time (4micro sec for long GI and 3.6 micro sec for short GI)
