- RAN Slicing tutorial from: https://github.com/srsran/srsRAN_Project/discussions/756
purpose:
- Slice 1: reserving a small BW for critical traffic by putting the UE having critical traffic on a different slice and setting minimum number of RBs to allocate to that slice
- Slice 2: no limit

- # Configure Slice 1
sst: 1 # Optional UINT (1). Sets the Slice Service Type. Supported: [0 - 255].
sd: 1 # Optional UINT (0). Sets the Service Differentiator. Supported: [0-16777215].
