How can I build a simulator for a wireless network (downlink)?

I would like to build a simulator for a wireless network (downlink) with the following parameters:

• The base station is positioned at the center of the cell.
• The cell coverage area is circular (radius 100 m).
• The users are randomly distributed within the cell area (uniform distribution).
• Assume a round robin scheduler where every user is given an equal portion of time for transmission.
• The pathloss model is: 𝑃𝐿 = 32.4 + 30 log 𝑑 + 20 log 𝑓c, where 𝑑 is the distance (in meter) between the base station and the user and 𝑓c is the carrier frequency (in GHz).
• The rest of the system parameters are as listed below:

Carrier frequency: 2.4 GHz

Bandwidth: 20 MHz

Shadow fading std: 7.8 dB

Transmit power: 20 dBm

Thermal noise: -174 dBm/Hz

Number of users: 50

May I know please from where should I start? May I get help please?
