2020-07-07

  1. Bronze and Bronze maintenance status update.
    1. Bronze done with 5 xApps
    2. Waiting for Samsung KPIMON and Viavi simulator output for the maintenance release.
  2. Cherry progress.
  3. How to contribute:
    1. Help with an existing xApp (Find an unassigned user story here https://jira.o-ran-sc.org/projects/RICAPP/ and contact me)
    2. Suggest a new xApp idea/.
  4. HCL is interested in contributing to the ML pipeline in xApp (QP) - followup by email
  5. Idea on how infra metrics could be used in xApps was discussed - in the O-RAN  architecture they should be only exposed to nonRT RIC, need to think if RIC's own infra metrics could be somehow used by xApps.
