Creation of a link list to get an overview (docs, readmes, wiki, ....):

Existing Information

  • AM/ML

  • ODU-High

  • OAM/SIM

Rest missing

  • needs to be discussed by email (ptl-private) 

  • did not happen - sorry

 

k-Release

  • reported page for deployment testing

  • continuous of functionality - > xTesting - robot test

L-Release

  • it/test continuation needs confirmation from RIC and AIMLFW PTL to update the robot test file

15min

OSC integration use case

@all

  • Details should be documented here: Release "L"

    • copy from B and reuse for L

    • use case setup by INT or by PTLs

      • each PTL provides a proper documentation

      • feedback by INT if it works

      • validates and approves documentation

      • INT requires definition of use cases

        • definition by PTLs

          • describe flows to be integrated and tested 

          • AI: Martin send to PTLs 

          • OAM/SIM / O-DU  /OAI (example) 

            • deploy OAM → 

              • connection supervision

              • what is a health check

              • PM to OAM to Grafana

              • flow related

              • FM flow

  • @Ankit Barve will take the lead for OAI + WLS + OSC DU HIGH integration

    • integration lab must work!!!

    • xFapi

    • Servers required 

      • currently in OAI lab and Radisys lab

      • NTUST: end-to-end test - see also slack

      • AT&T-Lab → COSMOS-lab → @Ivan Seskar

    • OAI team will be back from new years vacation and will start discussion this week with Ankit.

 

  • Jan 8, 2025

    • TM500 MUX log RSRP is not good compared to OAI. Bimo will ask VIAVI

    • Confirm to @Ankit Barve and @ASHWINI BHAGAT for configuration table of ODU Integration

      • Note:

        • ODU High change the Cell ID from 1 to 0

        • ODU Low may have different MTU size 1500 or 9000.

        • ODU Low set to 9BFP Dynamic (Ashwini told Sheryl to test with dynamic. This should fix to Static. Bimo Will confirm internally)

  • Feb 12, 2025

    • Ashwini analyze FH pcap and found from phystats couple of issues for SIB1 allocation.

      1. SIB1 allocation incorrect

      2. Why there is another RNTI as UE 0?

      3. Are there any packets drops in DL direction for these runs? Or some other check at ecpri level? For UE to detect and decode SSB, need to make sure RU is processing packets correctly and not dropping eCPRI packets.

      4. We can see that WaveJudge can detect and decode PBCH okay. What does UE see just for PSS, SSS and PBCH currently? Cell search will fail since it clearly looks like SIB1 allocation is not right but SSB should be detected at UE.

      5. Suggest to check on L2 and UE side

    • Ashwini asked for setup in Delhi but no response yet.

    • Ankit request info on how SIB1 decoded from intel API. He needs definition for frequency domain buffer from Ashwini.

    • Action item:

      • NTUST to do testmac and share terminal log and PCAP to all

      • NTUST to ask Viavi for error clarification

      • Ashwini to provide definition to Ankit

      • Ashwini to modify L1 config from 4x4 to 2x2

      • Ankit to modify L2 based on test result and definition

      • The next step will be discussed after resolve issues above

How to address e2e?!?!? 

  • required for e2e testing

  • What are O-RAN WGs/FGs defining!

    • Module up health check

      • ???  → O2?!??!?

    • Interface periodically health check 

      • e.g. OAM O1 WG#10 → ves healthcheck

      • e.g OFHM WG#4 → supervision

  • best practice from OTIC → TIFG

AI working on it!

  • security

  • e2, a1, o2, r1,  ...

  • 3gPP interface → F1, E1 

Idea of a "private" session in 2 to 3 weeks.

  • end of feb - Ankit 

  • OAI module

05min
