[srsran-users] gNB: Getting SCHED: Cannot fit pending UCI into PUCCH when using my COTS UE at band n66

[Pilato, Glenn - US]

Community, Designers,

We are attempting to use and S21 on band n66 on a srs-gNB running with a bladerf.   We are running into the the following warning which may be the reason we cannot RACH:

  // If any UCI information is triggered, schedule PUCCH
      if (bwp_slot.ul.pucch.full()) {
        logger.warning("SCHED: Cannot fit pending UCI into PUCCH");
        continue;
      }

Does any know what/why this is happening? Does this indicate that uplink has been scheduled by the gNB, but the UE has  not sent any information or information that could be decoded so the gNB will not longer has any more room to schedule new requests?  Does any one have any suggestions about how to proceed?   We are just starting to use srsran with real UEs now and are learning as we go.

Thanks,

GJP
