When you ran it with the scope as:

    ./dlsim -X

you saw no activity in the "PDSCH I/Q of MF Output" window,
so matter what SNR you put (even for very high SNR, say: ./dlsim -X -s40)

this commit seems to fix it.

I am not sure it is the end of story. The 2 threads PDCCH/PDSCH structures
may still not be used correctly everywhere.

the argument 'coded_bits_per_codeword' has to be an array in
case of several codewords.

The calling sites have been adapted.

Today, only the first index is used, so calling sites where
'coded_bits_per_codeword' is an integer pass the address
of it. It is expected that 'dump_dlsch2' will check in the
future that there is one or two codewords and only access
'coded_bits_per_codeword[1]' when it's sure there are
really two codewords.

Same as previous commit 41dda3d3
but for dlsim.

I'm not sure the fixes are correct.

                since two rx threads (even/odd) are used by OAI-UE

Beamforming is now only done when necessary. This patch is based on one from enhancement-10-harmony.

EPA channel model. -gV, -gW, -gX.

Adding the updated CSI option for retransmission of TB1 in TM4. Pass -U from the command line to enable.

The independent retransmission of TB1 will take data from the last PUSCH
report, when both TB were active and keep it for all the retransmission
rounds.
Now the TPMI for the retransmissions of TB1 is passed from the command
line with -K(tpmi): -K0 for Alamouti, -K5 for PUSCH column1 , etc.

Modifying some printouts into the file.

Intermediate commit. Adding HARQ support for SIC receiver. Changes in dci_tools.c to map TB to CW in a proper way.
Enable different options for TB1 retransmissions. Needs further improvements.

Counting for the number of 2CWs or 1CW retransmissions.
Adding corresponding changes to the phy_scope.
