I wanted to see the PRB consumption during UL/DL transmission using 5G toolbox.

I started with example NRCellPerformanceEvaluationwithMIMO, I wanted to see how PRB are consumed during UL/DL transmission. The PRB share in percentage that PUSCH FDD sceduling example is showing, tells about resource consumption. Should I add something to MIMO example to see PRB consumption due to PDSCH/PUSCH transmission? Theoretically, more users in a cell means more resource consumption, but in my case the PRB share reduces with increase in UEs. Can somebody elaborate it please?
