Guido Casati 8cf8a44e8e Handle division by 0 assert gracefully in average channel level calculation 
* nb_re_pdsch is directly linked to nb_rb_pdsch, if the latter is 0 the
  former is also 0
* compute average channel level only when number of RE for PDSCH is not 0
  the average channel level will be set to 0 otherwise
* Added a log message to handle this special case, which is consequence
  of other issues in the RX chain
* with this commit, the inconsistency in the RX chain will be handled
  in later in nr_ue_pdsch_procedures with a demodulation failure

other minor changes:

* Improved clarity by using NR_NB_SC_PER_RB instead of hard-coded value 12 in nb of RBs calculation
* cleaned up unused variable and outdated comments

Robert Schmidt 58335443b1 Revert "remove asserts on min RX/TX, set the RX/TX shift as 2 in the UE" 
This reverts commit 0d0e111135.  It was
set to UE RX to TX time to 2 as it was deemed that the UE could sustain
this time. However, we noticed a degradation of performance, so reset
the RX to TX time to something higher to ensure proper performance.

Laurent THOMAS 6379350f51 Correct data offset for unscrambling in PUSCH processing 
Correctly compute the offset of data to unscramble in PUSCH processing
at the gNB. Rename variables to make them easier to spot (instead of
"s"), and remove a global variable.

Closes: #734

Thomas Schlichter 5ac881b7c1 rfsimulator: add support to simulate a long propagation delay 
Add the option `--rfsimulator.prop_delay` to specify the simulated receive-path (gNB: UL, UE: DL) propagation delay in ms.
This option can be used e.g. to simulate a simple GEO satellite channel by specifying `--rfsimulator.prop_delay 238.74` to both, the gNB and the UE.

This is part of the work developed by Fraunhofer IIS within the ESA-funded project 5G-GOA (https://connectivity.esa.int/projects/5ggoa).
