Solve the NUM problem for $=3in$ a non$-SD-$RAN setup for a base

station with $30PRBs,5$ users with per$-PRB$ rates $R1=0\mathrm{.}05Mbps,R2=0\mathrm{.}2Mbps,$

$R3=0\mathrm{.}3Mbps,R4=0\mathrm{.}6Mbps,$ and $R5=0\mathrm{.}7Mbps.$ Which allocation policy $is$ optimal?

Solve the problem both analytically and using $CVX.$ For the latter, provide the code $as$

well.
