- changed Mdlharq to Mlimit when comparing with the round number
- Not incrementing the HARQ round in case of err_flag = 1, until HARQ is implemented
- Changed MAX_LDPC_ITERATIONS to 5 from 4 (provided better performance)

- Setting the payload to random data instead of all zeros at the Tx side

- Handling "nb_symb_sch" equal to 0 in "phy_procedures_nrUE_RX" which prevents
  entering "nr_ue_pdsch_procedures"

- Handling symbol loop problem in "nr_ue_pdsch_procedures"

- Handling resource block loop problem in "nr_rx_pdsch"
