I noticed a mismatch in the IQ width and compression method between the U and C eCPRI packets. While I configured the 9-bit block floating point compression in cuphycontroller_*.yaml, the C-Plane packet still indicated 16-bit no-compression.
I tried to configure my RU, but it still follows C-Plane compression instructions.
How can I change the compression config on C-Plane packets? Change in source code or configuration are both fine for me.
Thank you very much.
Hi @vantuan_ngo ,
Aerial code currently supports static data format (please see attached for the related section of the ORAN_FH specification) . It is expected that the O-RU should not use udCompHdr fields in the C-plane messages.
Thank you.
Yes, I see. It is the problem of RU implementation. But, can we fix it from DU side. It is not possible for me to update RU firmware now.
Hi @vantuan_ngo,
This is currently what we support on the DU side. Please let us know if you need help with any other issue.
Thank you.
Hi,
To work around my RU, I uncommented these lines of code to make cuBB send C-Plane msg according to the configuration.
Thank you very much for supporting.
Hi @vantuan_ngo ,
It is correct that un-commenting these lines can be a work-around for your current setup.
Please note that we had commented out these lines to be compliant with the O-RAN specification.
Thank you.
