The UE PHY loading simulator creates a set of simulated UEs at the MAC and PHY layers.
These simulated UEs can be active or idle.
To add simulated UEs to the ENB PHY:
enb uepool sim active=<num> idle=<num>
In the enb uepool chans outputs, simulated UEs are marked with an S following the RNTI.
To remove all of the simulated UEs from the ENB PHY:
enb uepool sim clear=true
