Florian Kaltenberger 7fb14ab321 adding MAC part of 5G FAPI interface for PUSCH. Since the previous version was incomplete anyway I merged in the new SCF specs and used those (only for PUSCH). Todo: implement PHY part. 2019-09-05 16:40:31 +02:00

Ahmed Hussein 53e6a5223c Minor Fixes in ulsim 2019-08-23 16:08:57 +02:00
Ahmed Hussein f398e4999b Set start_rb to 0 
- start_rb was set to 30, and nb_rb was set to 50 with NB_RB_DL = 106.
- When the DC subcarrier is included in the RB allocation,
  this causes errors in FFT/IFFT operations arounf the DC subcarrier
- This leads to errors in unscrambling and decoding

Ahmed Hussein 2660f4ea4f Added frame loop to ulsim 2019-08-23 16:08:57 +02:00
Ahmed Hussein 0e78faa744 TBS fix at UE side + minor restructuring in "phy_procedures_nrUE_TX" 
- TBS calculation was performed 2 times. Once in "phy_procedures_nrUE_TX" and
  another in "nr_ue_ulsch_procedures". The TBS calculation was wrong in "phy_procedures_nrUE_TX"
  and correct in "nr_ue_ulsch_procedures".

- The data generation was performed in "phy_procedures_nrUE_TX" with a wrongly
  calculated TBS because "ulsch_ue->nb_re_dmrs" wasn't set to a value, so the calculated
  TBS would be more than it should be. This doesn't create a problem in the test because
  the comparison between the TX and RX data is made using the correctly calculated TBS
  which is smaller.

- Solution was to perform data generation in "nr_ue_ulsch_procedures", and remove TBS calculation
  in "phy_procedures_nrUE_TX"
