However, after the simulation, I have used the command simulation_results.plot_BLER_throughput and the shown results are the same of the AWGN channel model! Anyone has an idea how to generate the BLER curves for TU channel? What happens to the CQI thresholds in this case? Are the same of AWGN?

yes, the CQI threshold is the same irrespective of the employed channel model, MIMO mode,… since we employ SINR averaging to map the SINR onto an effective AWGN-equivalent SNR (see “Throughput maximizing feedback for MIMO OFDM based wireless communication systems” for details on this process).
Regarding your simulation setup, it should basically work as far as I see. Did you check whether the corresponding results files in ./examples/AWGN_BLER_curves have been updated after your simulation? You can just load one of the files stored in this directory and check LTE_params.ChanMod_config to see which channel model has been used in the simulation.
This is exactly what I have done: I have compared with the stored results and didn’t saw any difference…
I have a data set generated by the author of another LTE Simulator (the LTE-Sim, from the Giuseppe Piro) and he have stored a series of values that I am also using as a reference (I can post some values here).
