Dynamic PRB Allocation

[Bara Sabbah]

Dear 5G-LENA Community Members,  

Is there a way to dynamically control how many PRBs are available for UEs from the gNB during simulation (in Uplink)? . I’m trying to vary the total available resources over time to reflect changing network conditions (control of available PRB is necessary in my scenario).

I believe this might require modifying the "NrMacScheduler"  class (or related classes), but I’m not sure how to approach it.

Is there a way to control available resources over time without directly changing the scheduler? Or has anyone implemented something similar?

Thanks in advance,
Best Regards,

Bara Sabbah

I think you should be able to accomplish this by setting different notching masks over time.

When a notching mask is applied, does the UE transmit only on the non-notched PRBs? In other words, is it scheduled exclusively on the remaining PRBs, and is its transmit power distributed only over those PRBs or across the entire BWP?

[Gabriel Ferreira]

Yes. For power, make sure uniform power allocation is not used. I think it is off by default.
