Reply LS on applicable functionality reporting for beam management UE-sided model
From Samsung
Summary
Samsung's response to RAN2's liaison statement regarding applicable functionality reporting for beam management UE-sided AI/ML models, containing 4 key observations about terminology definitions and 3 agreements/conclusions on configuration procedures and CSI reporting mechanisms.
Position
Samsung advocates FOR a flexible CSI framework-based approach to AI/ML functionality management with clear separation between supported, applicable, and activated functionalities. They push FOR allowing multiple CSI reports for inference based on UE capability and support associated ID usage for consistency. They are AGAINST immediate activation of CSI report configurations upon receiving Step 3, insisting on proper applicability reporting procedures first.
Key proposals
- Observation 1 (Sec 1): The concept/terminology 'functionality' of Supported functionalities may refer to UE-capability information/parameters i.e., Rel-19 AI/ML-enabled Features/FGs
- Observation 2 (Sec 1): The concept/terminology 'functionality' of Applicable functionalities may refer to CSI-ReportConfig for inference configuration or a set of inference related parameters
- Observation 3 (Sec 1): The Activated functionalities may be enabled based on CSI framework
- Observation 4 (Sec 1): Therefore, the meaning and the granularity of 'functionality' for Applicable functionalities, Activated functionalities and Supported functionalities may or may not be the same
- Agreement 1: In Step 3, following configurations are provided from NW to UE: UE is allowed to do UAI reporting via OtherConfig, with applicability report based on A) one or more CSI-ReportConfig for inference configuration and/or B) One set or multiple sets of inference related parameters
- Agreement 1: CSI report configuration for UE-side model inference can't be activated immediately upon receiving Step 3
- Agreement 1: In Step 4, UE reports applicability for all the above A) one or more CSI-ReportConfig and/or B) set(s) of inference related parameters
- Agreement 1: Applicable periodic CSI Report is considered as activated only if the applicability of the corresponding CSI-ReportConfig is reported in RRCReconfigurationComplete
- Agreement 2: For beam management, multiple CSI reports for inference for UE-side model can be configured/activated/triggered, which is up to UE capability
- Conclusion: For the CSI-ReportConfig for inference configuration provided in Step 5, periodic CSI Report is considered as activated after RRCReconfigurationComplete
