      - Msg2 scheduler used for testing purposes was removed
      - Now the UE tries to DCI 1_0 scrambled with RA_RNTI in the RA window

      Introduced a delay after a completed sync before starting msg1 generation: · ec422f70
      cig authored
      - this was necessary because as soon as the gNB starts, it tries detecting
        the prach preambles and it mesaures the background noise. However, there is
        a delay of several dozens of frames before it considers the preables as
        detected.
      - the solution at the UE consists in avoiding sending preamble as soon as the
        UE syncs by introducing an offset, this keeps the power measurements low at
        gNB side as long as the preamble detection counter is under threshold
