05min	admin	bimo fransiscus asisi	Next meetings Tue 2025-02-11 9pm EST by Rittwik Jana Wed 2025-02-19 8am EST by Martin Skorupski Tue 2025-02-27 9pm EST by Rittwik Jana - canceled due to O-RAN f2f in Paris? Wed 2025-03-05 8am EST by Martin Skorupski L Release Timeline
10min	Email Thread: Access to OSC INT Server	@all	Related debugging session are scheduled. Connection issues to the Taiwan Lab by Ashutosh now - Please raise status in Slack!!! Connection issues to the Taiwan Lab by Ashwini - Fixed Item to be removed for next week.
10min	Configuration with OAI at Taiwan Lab	bimo fransiscus asisi c/o Martin Skorupski	Ankit Barve, ASHWINI BHAGAT confirmed configuration used in https://hackmd.io/fx7gYOpHSNSJOe0De1aaRA?view#Configuration
10min	E2E testing		bimo fransiscus asisi: can this section be deleted from the agenda in future?!?! __ 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 integration issue between robot and xTesting PTLs → common template https://hackmd.io/@q-eiMFW8TLa2Pa3QKECMzw/SJXLyJDNJg input preferred from James about xTesting and its advantages. 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 AI: Martin: kick off an email no answer follow up by Martin There are options for O-RAN f2f ... but some requirements should be exchanged see O-RAN-SC RSAC Slack.... https://o-ran-sc-lf.slack.com/archives/C07CT61549M/p1735998051389359 OAI team will be back from new years vacation and will start discussion this week with Ankit. Goal: O-DU Integration with RU-sim UE-emulated Ankit share the parameters that need to be tested. Table for ODU High parameters in https://hackmd.io/fx7gYOpHSNSJOe0De1aaRA?view#Configuration have been confirmed Ankit(parameters are OK). Slack discussion is ongoing but no response from Intel yet. Ankit: RAN Integration should be come together since need expertise from each component and cannot be done by only a single person. Suggest to have debugging call regular week to solve the blocker. ODU High still testing K release so stick with I Release. 08 Jan 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) 12 Feb 2025 Ashwini analyze FH pcap and found from phystats couple of issues for SIB1 allocation. SIB1 allocation incorrect Why there is another RNTI as UE 0? 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. 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. 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	O-RAN F2F Paris 2025-02-24+	Martin Skorupski	Per ToC - would be nice of have a running demo in the "networking area" time until ~mid January Martin - reach out to OAI for a joined Email conversation is ongoing - no decisions yet... 90min session as a normal slot 30min Alex - DHCP configuration of O-RUs according to WG4 Spec 30min John - rApp Manager 30min Sirdhar - OAI and Performance Measurements (martin to Sridhar)
10min	Q/A	@all
