Nope, you are not taking into account the quality of the transmission.
Based on the CQI (Channel Quality Indicator) that the UE transmit to the
eNB, the eNB computes the MCS to use. Higher MCS lead to higher throughput.
I'm not even reconsidering re-tx here, which should also be taken into
account.

What changes should be applied in order to schedule more users per TTI?

You need to craft additional DCIs in regions not previously allocated for
broadcast or other UE data.
Use the bitmask to organize such control elements.

Cheers,
