cig 12b585a190 Fixes to RA procedure 2020-05-12 17:19:10 +02:00
cig ec422f7050 Introduced a delay after a completed sync before starting msg1 generation: 
- 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
