[srslte-users] 20% of PDCCH miss

Dear all,

I confirm that. It seems like the pdsch_enodeb generates the DCI for 0xffff
badly.
What I tried was recording a trace file with
pdsch_enodeb -o file -m100
and decoding it with
pdsch_ue -i file
what you get here is that the second synchronize, but cannot decode
anything. PDCCH miss 100%
if instead you try
pdsch_ue -i file -r 1234
you get 20% PDCCH miss as Bahar reported.

It looks like the receiver can decode the messages for the intended user,
but not the broadcast ones.
Best,
