question about function set_slice_resources(slice_idx: int, slice_mask: str) #10

Open hanghoo opened 1 week ago

hanghoo commented 1 week ago

Hello,

I was wondering if the function set_slice_resources() can be used to assign specific PRBs (index) based on channel conditions for different slices.

In addition, I read the paper "Intelligence and Learning in O-RAN for Data-Driven NextG Cellular Networks". It looks like this type of resource scheduling does not support at the DU. What do you think of it?

Hello,

At this time, and without introducing further modifications to the code, you can only allow a specific slice to use or not certain RBGs.

Hi @leonardobonati,

Do the RBGs need to be specified in the conf file? Thank you very much.

leonardobonati commented 1 day ago

Hello, you can specify them in the config file for them to be written as the initial configuration. Otherwise, you can manually set them in the slicing_allocation_mask_tenant_X.txt files, where X is the slice ID (https://github.com/wineslab/colosseum-scope/tree/main/radio_code/scope_config/slicing).

Hi @leonardobonati,

Thanks much for your explanation. Based on this, I understand that the slicing group is a hyperparameter, not learning from Agent, right?

If this is the case, why do I see the output of xApp sched-slicing PRB is dynamic instead of predefined? Thank you very much.
