I am currently using the Aerial testbed, but I encounter the following error when attempting to connect multiple UEs simultaneously. I would like to know what this error means and how to resolve it.
Thank you in advance.

Hi @furuki-takuma409 ,

These errors occur every 8 frames, and we have observed a similar error due to SRS. Could you capture the SRS PDU in the FAPI message and confirm whether all parameters are valid?

Thank you.

I also suspected SRS. So in my environment, I turned off SRS.(in cuphycontroller, enable_srs=0 ).
But it still happend.

I found this error caused by newer UE.

I suspect there is a mismatch between recent UL C-plane communication and cuBB processing, resulting in errors in the UL C-plane communication (possibly involving SRS).

Currently, it is working correctly by using only the old UE.

If all PDUs in UL_TTI.request are valid, L1 drops SRS PDUs in the message with enable_srs: 0.

Error type 3 indicates a functional error when generating the corresponding C-plane messages.

Based on these clues, I think the UL_TTI.request was broken due to SRS.
If you need to investigate the cause of this issue, please capture the FAPI message and ensure all the PDUs is valid.

Thank you,

In addition, please disable SRS on the OAI side and try again.
