Hi,
I use LTE-A Link Level Simulation v1.4, and I have a question about HARQ.
when it calculates the throughput, the HARQ is considered or not?
I do the simulation in SUSISO simulation type, and 1.4MHz, and I checked the rv_idx is always ‘0’.
It means the HARQ and retransmission are working?
(I couldn’t find any part which HARQ effects the throughput calculations)

Hi,

did you set LTE_params.max_HARQ_retransmission > 0 in LTE_load_parameters?
did you deactivate feedback: LTE_params.UE_config.feedback = false? (if not, the CQI is adapted and there might not be a need for retransmissions).

If this is done, you should get retransmissions.

Best,
Stefan.
