[srslte-users] PRB Allocation and Active UEs

[Ayman Maghrabi]

Hey Francisco,

Thanks for the info. I'm OK with using time domain Round Robin, I can just
customize the allocation to chose from different pools of PRBs.

I actually want to read the QCI value associated with each UE. I know that
QCI is used for upper layer connections, but I'm considering to use it to
define the two set of UEs with different PRBs.

Regards,
Ayman Maghrabi
