This Liaison Statement informs all 3GPP working groups about the completion of the Study on AI/ML consistency alignment.

Technical Contributions

Study Completion

TSG SA has completed the Study on AI/ML consistency alignment, with the following deliverables:

  1. TR 22.850 v1.0.0 - The technical report documenting the study findings was approved at SA#110
  2. CR 0128 on TR 21.905 - A change request to TR 21.905 was approved to establish consistent AI/ML terminology

Terminology Standardization

The key technical contribution is the definition of consistent AI/ML terminology to be used across all 3GPP working groups. This terminology has been captured in the approved CR to TR 21.905, which serves as the 3GPP vocabulary specification.

Work Item Closure

  • No further work is planned on this study activity
  • The study item FS_AIML_CAL is considered complete

Actions Requested

TSG SA requests all recipient groups (TSG RAN, TSG CT, and all SA, RAN, and CT working groups) to:
- Take note of the completed study
- Apply the standardized AI/ML terminology defined in the updated TR 21.905 in their respective work
