Question About Aerial SDK ARC-OTA compatibility, we are using
Openair RAN 2024.w21+ARC1.5 with Aerial 24-2.
We are seeing issues with the L1 being configured by L2.
This are using the docker compose process with two containers supported in the openair build system. I exported/copied out the nfapi-date.tar.gz to use in the openair build but am seeing some errors with the fapi messages being exchanged, where the L1 (cubb) ends up erroring out

I had seen similar issues with the aerial23-4 version with older versions of openair so I updated to get best known versions from the document.

L1 Configs:

l2_adapter_config_P5G.yaml
L2 Configs:

Are there any possible missmatched versions of config options? I can attach L1/L2 configs if needed

Hi @eric.a.momper,

Can you please attach the L1/L2 config files? Can you also share the nvipc.pcap log? You can obtain the nvipc pcap log with the following:

# Usage: sudo ./pcap_collect <prefix> [destination path]
sudo $cuBB_SDK/build/cuPHY-CP/gt_common_libs/nvIPC/tests/pcap/pcap_collect nvipc

# The nvipc.pcap can be seen at current directory (by default) or the inputed "destination path".

Thank you.

Hi @bkecicioglu ,

Thanks

Hi @eric.a.momper,

Aerial SDK currently supports PRACH preamble formats 0 and B4. The PRACH configuration index value of 98 is used in your CONFIG request message. This index corresponds to the preamble format A2 for FR1 (see Table 6.3.3.2-3 of 3GPP 38.211 v16.2.0).

Can you correct this setting and try again?

Can you also please share the phy.log from your initial test?

Thank you.

@bkecicioglu
Thanks for this info i looked in the table and tried a few values, 0,145,158,159

L2 config/output:
gnb.conf prach_ConfigurationIndex = 159;# testMAC 158; OAI gNB 98
oai L2 debug output pack_nr_tlv: TLV 0x1029 with padding of 3 bytes

I seem to be getting the same data in the rach section of the pcap reguardless of what the prach_ConfigurationIndex is set to are there additional settings that correspond with this, or from looking at the phy.log and the l1 fapi recieve code, could there be an issue with the message encoding/decoding?

Hi @eric.a.momper,
I have tested with prach_ConfigurationIndex = 0, 145, 158, 159, and I can see the correct values in the config.request for all of them, though there is an issue with 145 that we will look in to.

My configuration files are here: ci-scripts/yaml_files/sa_gh_gnb · 2024.w21+ARC1.5 · oai / openairinterface5G · GitLab

I think the gnb.conf im using should match that one the only difference i saw was what cfg index I set, ill look into if its an issue with how im building/running the OAI L2, is that wireshark plugin/ dissector something available? would make it easier to compare things changing vs expected values, as i was seeing all the same as i posted/ orig pcap despite changing the config idx

10

Hi @eric.a.momper,

Please see attached for the wireshark plugin. Once added, you can modify the options from preferences>protocols>NVIDIA_FAPI.
scffapi_nv.lua.zip (27.1 KB)

11

@eric.a.momper Do you use SCF FAPI version 10.02 or 10.04?

12

Thanks for the wireshark plugin seemed the pcap disected ok, i think i had an issue with how i was copying out the pcap from the container double checking that, i comipled aerial 24-2 with cmake .. -DCMAKE_TOOLCHAIN_FILE=cuPHY/cmake/toolchains/native -DSCF_FAPI_10_04=ON

13

Please make sure that the length field of the CONFIG request TLV is encoded as uint32_t. This is what we expect if SCF FAPI 10.04 is used. In your pcap, I can see that the length field is encoded as uint16_t. This will cause parsing errors in the CONFIG request message.

14

Thanks for the explanation, i was suspecting something like that, it looks like on this branch of OAI the L2 config ecoding devolves to packing as u16

uint8_t pack_tl(nfapi_tl_t *tl, uint8_t **ppWritePackedMsg, uint8_t *end) {
  return (push16(tl->tag, ppWritePackedMsg, end) &&
          push16(tl->length, ppWritePackedMsg, end));
}

would it be easier if i rebuild aerial without the 10_04 FAPI? or what is the recommened option for running the ARC OTA with a Foxconn Radio?

15

@bkecicioglu
Thanks, For this info
rebuilding without -DSCF_FAPI_10_04=ON i saw L1 was able to get futher and send a config response

@eric.a.momper That is great!

Let us know if you are having any other issues.

Hi @eric.a.momper the default cmake flags are configure to work with the oai L2+ in the ARC 1.5 release as it is.
https://docs.nvidia.com/aerial/aerial-ran-colab-ota/current/text/installation_guide/validate_setup.html#start-aerial-cubb-on-the-gnb
The -DCMAKE_TOOLCHAIN_FILE=cuPHY/cmake/toolchains/native flag came with the 24-2 release of aerial
