You can also try a different PLMN like 99999 or 90170

Could you try the gNB PLMN and IMSI combinations from this table? https://docs.srsran.com/projects/project/en/latest/knowledge_base/source/cots_ues/source/index.html

@tilldroemmer any updates on your issue? Could you try tuning TX/RX gains on both gnb and srsUE?

@tilldroemmer do you run the experiments over an RF cable? In the UE logs you need to filter for `PRACH:|PDSCH:` with `grep -rE "PRACH:|PDSCH:" ./` then you can see that...

Do you have any attenuator in between?

you mean you are not adding any external attenuators, just using the built-in ones?

ok, that is good. In the logs you have provided, do X and Y stands for gnb tx_gain and srsUE rx_gain? did you try other values for gnb tx_gain than...

you do not need to repeat it 3 times. If the parameters are good, it should work out of the box. what about the `time_adv_nsamples = 300` in srsUE config?

did you try with `time_adv_nsamples = 300` ?
