Description

I just realized that OsmoPCU would also require related changes/enhancements. Contrary to the circuit switched domain, we never used frequency hopping at all for the PS domain, no matter which base station hardware.

At the very least, we would need to be able to
  • pass the hopping parameters (MAIO, HSN, ...) over the PCU socket so the PCU knows about them
  • encode the hopping parameters in any kind of RLC/MAC messages, specifically
    • Encoding::write_immediate_assignment()
    • Encoding::write_packet_uplink_assignment()
    • Encoding::write_packet_downlink_assignment()

There are possibly more required modifications, the above is not meant as an exhaustive list.
