- there was this vote (on moving the code freeze to Nov-4) in the Oct-09 ToC meeting: "There is a formal request. In the Amber release this schedule was ambitious process. One of the goals is to get people to get familiar and start contributing. Code freeze is supposed to occur at the end of this week. The developers enter a maintenance cycle. To get a release out we add a maintenance release. So the developers can continue to fix defects while everyone plans on what the new features are in the B release. This next window October 14 - November 2 is time to work on fixing bugs on the software only for this release. We should allow this extension because there is not enough code to do end to end testing." I am not sure how to interpret this. But is my understanding correct that after Nov-4 (the code freeze date) we will have a two week cycle in which only bug fixes go to the master branch and only after this two week cycle we branch of an Amber release maintenance branch? New code development cannot be committed to master during this 2 week cycle? Do we already have a plan on how we do and who does this branch off?

- We have 2 weeks and then we will have our updated code freeze.
- We will freeze code November 2 and then a few weeks of defect fixing, then freeze and branch the code. We will document the code during the code freeze and then have our release. Once we branch the code we will return to a maintenance cycle in January. The maintenance release will run through Feb 1. This is projected for B. We have not finalized the B plan. Dec. 2 we will start Epic identification. RSAC will come with their use cases and details. We take off from December 21st to January 6th. If changes need to be made make them now. They need to be finalized in the next few weeks.

- Matti Hiltunen RIC Applications (RICAPP)
- Thoralf Czichy RIC Platform (RIC)
Below a list of changes to repos (new ones, as well as deletions) under the RICP (near-RT RIC Platform) that we would like the TOC to approve. Parts marked with RICP/RICAPP are proposed by Matti and I (PTLs for RICAPP and RICP) and parts marked with RICP only me as PTL.
(WE1) Project RICP
ric-plt/resource-status-manager
- Summary: Implements the management of Resource Status messages over E2
- Description: The Resource Status Manager is responsible to control the generation of
Resource Status messages sent by the RAN to the RIC by issuing Resource Status Requests.
The RSM provides an API that allows to start and stop the generation of these messages as
well as to issue specific request commands. The RSM provides also default values which are used
whenever a new RAN (eNB) is added to the RIC.

We (RICP and RICAPP PTL) would like to remove the following repositories:
ric-app/demo (empty)
ric-app/reporter (not maintained anymore for 6 months (and actually confusing community if someone uses this as reference) and e.g. the measurement campaign xApp can replace it)
com/asn1 (an ASN.1 compiler for which we found that it causes to much issues that we had to troubleshoot. We already switched to using com/asn1c (which is derived from https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_vlm_asn1c&d=DwIFAg&c=LFYZ-o9_HUMeMTSQicvjIg&r=Tnwenk7t78Qk7cMlMZ90EGmbng6eVuV4yQNhqbtpKkk&m=xoq2zMpPhab9uHOEBVXWXAFXjPsyFpAgdbNtyADOnwY&s=Rkl10dXpdSlyLJTKlTd3zwy98meppgWMQ_0PNWZ8QjQ&e=)(WE3) Project RICP
new repo: ric-plt/ric-test
- Summary: RIC platform-specific testing that are not specific to a single RIC component
- Description: This repo includes test cases that span the full RIC platform, i.e., that cannot run against a single RIC component. This may also include
simulators related to the E2 base protocol, or related abstract test xApps (that do not actually implement 3GPP specifications). Note that the test
cases must still be limited to RIC platform only. If you want to write/check test cases that integrate also other O-RAN SC components, check
the it/test repository.

new repo: ric-plt/ric-dep
- Summary: Code and configuration files that are needed for deploying a near-RT RIC platform instance
- Description: This includes, for example, helm charts for RIC platform components. In this we can make assumptions about the underlying k8s already existing or
we can also spin up blueprints for such a deployment. Note that this component is intentionally limiting itself to the RIC platform and does
not include other O-RAN SC components. For such you might want to look at the it/dep repo managed by another O-RAN SC project.

- Initial committers: (first one AT&T, the other two from Nokia): Lusheng Ji (lji@research.att.com) , Prabhu K ( prabhu.k@nokia.com ) Ranjit Angajala ( ranjit.angajala@nokia.com )Note that this needed for legal reasons to clearly define the scope of the near-RT RIC project. It is aligned with a "scope" wiki text that we wrote for the same reason.
Also note that we continue with the it/dep repo as a general integration repo where any O-RAN SC components can be integrated together. In scope of their work on
integrating all O-RAN SC components, engineers working on the it/dep repo might re-use some of the functionality that was original committed to ric-plt/ric-dep .(WE5) Project RICP/RICAPP
We would like to remove the empty ric-app/uemgr and instead create a new repo under ric-plt/. This is in order to clearly link
the demo xApp to the RIC platform project. At the same time also note that the license of this is changed to a documentation
license. So that its legal scope reflects its actual role in the RIC platform. Naturally there will continue to be actual xApps under the
RICAPP project. Placing it under the RICP project (and not RICAPP) allows Nokia to contribute to it. The name is intentionally kept
generic. As part of this change we also move this page https://urldefense.proofpoint.com/v2/url?u=https-3A__wiki.o-2Dran-2Dsc.org_display_RICA_UE-2BManager-2BxApp&d=DwIFAg&c=LFYZ-o9_HUMeMTSQicvjIg&r=Tnwenk7t78Qk7cMlMZ90EGmbng6eVuV4yQNhqbtpKkk&m=xoq2zMpPhab9uHOEBVXWXAFXjPsyFpAgdbNtyADOnwY&s=gaI_Yvwbqi4X3KKgd2KlO1cau-oPGsKTpA0lo3SzHeo&e= to the RICP project (a reference

We delete the following repo: ric-plt/ue-nib . The scope of the RIC platform does not include this functionality. If, then
such functionality should be developed outside of the RIC platform, e.g., under the RICAPP project. Some of the earlier functionality (read and write
of the demo data that is actually needed in the "demo1" demo xapp (under documentation license) is moved into the demo1 repo as it is
closely related and does not make too much sense as standalone documentation repo. Note that this implies that the functionality is now under
document license in ric-plt/demo1- Empty repos are allowed to be deleted. Repos with content are open source and remain for historical reasons.
- Needs to be marked as depricated. When we complete the Amber release there should not be code dependencies. Therefore we can remove the repos because this is the first A release.
- The RIC platform as an entity must be open source contained platform. When you cross over to system integration is work in a different project that will rely on the RIC project but other people on different licenses won't be able to participate.
- E2 was removed due to legal issues.
- RIC PLT E2 had files ASN1 files that were not supposed to be there. That compiler was used in early development but won't be used again.
- Concern about putting this in documentation license downstream and someone contributes back to a test repo then it becomes a part of the test by the integration team.
- That is acceptable.
- Empty repos are allowed to be deleted. Repos with content are open source and remain for historical reasons.

- Discussed traffic churn use case with different values. We should prepare for that. We are going to look at our spreadsheet of epics consolidate and move on to call flows. It's in a word document with some call flows. I am hoping that Thoralf Czichy and Matti Hiltunen will discover algos that will work with xApps. Talked to Samsung about CU DU binary code for an example. Jin Sun said their management will look into it. Radisys agreed to provide a CU DU binary.
- As part of the release planning when we get into the B release we identify the epics. Yes there is an approval. This is the version of our requirements and use cases as part of the B release. That package should be brought to the TOC for a vote to freeze the target environments.
- When does that happen?
- December 7th once the epics are identified we should freeze it so the projects can commit to B release. This gives the development team to groom their user stories.
- When does that happen?
- How many end to end use cases?
- One
- Jack would like to see a simpler e2e base line "hello world" use case that demonstrates that the platform is working. It is a simple metrics use case that can exercise the components and return metrics on the different components running in place. We need a use case that we maintain for the basic level of operation before talking about complex. We want a base line use case that exercises the system and gathers metrics. A heartbeat check. This way everyone is at a base point before advancing their use case. There should be a self diagnostic test so the platform is base lined.
