      Adapt RACH procedure for large delay · 6f9f542f
      Bo Zhao authored
      - Add CL options for additional DURATION_RX_TO_TX and k2 value at UE, additional k2 at gNB
      - Apply additional DURATION_RX_TO_TX at UE
      - Apply the additional k2 at UE for scheduled msg3 by RAR and scheduled UL transmission by DCL. Re-compute the next Tx frame number
      - Apply the additional k2 at gNB for scheduled msg3 and scheduled UL transmission. Re-compute the next Tx frame number
      - Increase the RA window counter for reception of RAR
      - Fix the data type for larger slot number in function get_samples_slot_timestamp
      - Example for a one-way delay of 120ms: run gNB with "-P 7372800 --gnb_k2 480", run UE with "-P 7372800 -A 14745600 --ue_slot_Rx_Tx 480 --ue_k2 480"

      Lower scheduler PF averaging constant · 8ad215f6
      Robert Schmidt authored
      This time constant plays a major role in how long a UE has to wait
      maximally before it might be scheduled. For instance, if a UE had a lot
      of traffic, the average traffic will be high, pushing the PF coefficient
      down. If another UE with no traffic in the past becomes active with
      heavy traffic, the first UE might not be scheduled for an extended
      period of time.
      
      In the AW2S-Amarisoft UE CI test pipeline, we sometimes see that the
      maximum number of RLC retransmissions was reached. While this might not
      be the (only) cause, scheduling a UE more often might prevent such
      situations, and we saw an improved stability.
