- China Mobile wants to propose opening the CDLA. This is a brief introduction. Action/ Jinri Huang will shared slides to set up projects using the SC.
- Jack - we need to form a working activity to spend time talking and thinking it through. The data is always a rich place for discussions. The TOC doesn't have enough time to work it out. We need to report back to TSC what our plans and goals are starting this new effort. We should go through a process and talk to people and we're doing it right.

- O-RAN Alliance spec license restriction for ASN.1 spec (raised by Thoralf)
- Jack has been talking to Stephan (O-RAN Alliance lawyer) to address the O-RAN Specification copyright in the O-RAN SC. There are discussions going on an alliance with TIP and with TMC.
- From 3GPP we have submitted several requests about copyright usage. We've submitted requests twice and they've come back for more clarification. We are working through the standards groups to get done.
- Jack has been talking to Stephan (O-RAN Alliance lawyer) to address the O-RAN Specification copyright in the O-RAN SC. There are discussions going on an alliance with TIP and with TMC.
- O-RAN Alliance spec license restriction for Yang model (raised by Martin)
- Jack: Is it a copyright issue?
- Martin: Yes, not clear how to use 3GPP data models
- 3GPP models are broken from syntax and how can we fix them? By working group 1 license statement. Latest ask by 3GPP is still not addressing our needs. Next version coming out in March is not useful and I can'tuse them in the Bronze.
- Are you using them as a baseline?
- We have modified once and found we are not allowed to modify.
- We demonstrated at one event but I can not share the modeified ones with the public.
- Likelihood high that all has to be modified and tested.
- Clear statement that O-RAN Alliance should use and influence 3GPP but 3GPP is not used in the software community.
- Any comments or thoughts?
- Tracy: Thinks this topic will be discussed during WG1 modeling discussion at 5PM EST today. The goal is to getting this resolved but it's organizationally complicated across 3GPP and the O-RAN Alliance.
- Martin: I am careful in selecting to avoid future issues.
- Jack: There needs to be an abstraction layer. Once solved every time there is a change to the system doesn't it have to cascade through these layers.
- Martin: The model was supposed to be the abstraction layer you will have a model on a model with a 1:1 relationship.
- Jack: We're running into problems because we're tying to specifications that were never validated.
- Martin: That is why I am selecting young data models. But the RAN specific stuff will be problematic.
- Jack: We're running into problems because we're tying to specifications that were never validated.
- Martin: The model was supposed to be the abstraction layer you will have a model on a model with a 1:1 relationship.

- Yingying: O-CU will focus on U plane. No contribution on RRC part. UE attachment will be a problem in B release. E2 still under discussion with main contributor. E2 will be discussed in following weeks in WG8
- Jung/Rittwik: O-CU not advanced enough to provide enough metrics to support traffic steering. Fallback plan needed, enhancing E2 simulator to provide enough support. Can SIM project support this? Otherwise traffic steer is in jeopardy. O-DU has a plan to support. But need O-CU support as well. Need ToC decision on the fallback plan.
- CoChairs: Construct document for what's missing. Is this possible in Cherry or even further out?
- Rittwik: RSAC to provide document on what's current, what's future, suggesting alternatives.
- Jack: It will be a weak message if this cannot be supported.
- Second use case (healthcheck) Non-RT RIC making progress
- Action: Allocate a time slot next week to discuss.
