Cedric Roux 3089dc0d45 rlc v2: update to latest develop 
All previous commits for rlc v2 are proably
not functional or even compiling.

Cedric Roux 123745118c rlc v2: hotfix: remove some AssertFatal 
Not sure if the problem is in the MAC layer or in the RLC v2 layer.
Maybe the buffer status reporting in RLC v2 is not good. Let's remove
two AssertFatal in the MAC for the time being.

Cedric Roux 4b6f5cea52 rlc v2: have the L2 simulator functional 
Not very clean, but will do the job for the time being.

Cedric Roux fbd69663b1 rlc v2: fix for CU/DU split 
Limitation: this fix only works if there is only one eNB,
because we force module_id = 0 in the function deliver_sdu where
(as the code is today) we have no way to know which module_id is
concerned. More generally, the rlc v2 does not work with more than
1 eNB.

Cedric Roux 8ca42918d6 hotfix: remove an AssertFatal 
The UE code to compute BSR is too complex, has to be reworked/simplified.
This commit just removes the assert, does not solve anything.

Cedric Roux eebf2cb938 rlc v2: improve buffer status reporting 
The old method was wrong.
The new method is better, but not accurate, especially when the
TX buffer contains SDU of size > 2047 bytes.

Plus it's probably too slow.

To be refined at some point.

Cedric Roux 3310f5c6b0 alternative RLC implementation 
This commit introduces an alternative RLC implementation
based on 36.322 version 8. AM and UM done, TM not done.

See openair2/LAYER2/rlc_v2/TODO for missing parts.

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

Robert Schmidt a56be93e80 Reduce CPU load in PHY stub UE (L2 sim) 
Instead of looping over UEs and all DL config Req/HI DCI0, loop first
over all DL config Req/HI DCI0, and for each, match UE.  Lowers CPU
traffic for high traffic situations.
