InterDigital, representing RAN2, clarifies that NG-RAN involvement in UE-side data collection is limited to providing radio measurement configuration, specifically for the beam management use case, while explicitly stating that RAN2 has not concluded on the level of NG-RAN involvement in the actual data transfer process. They define standardized data as content explicitly defined in 3GPP specifications, ensuring the network can understand its meaning, and assert that full MNO visibility allows verification of collected versus reported data without requiring an SLA. RAN2 opposes the assumption that gNB or LMF are in charge of 'initiating, terminating and fully managing data transfer,' restricting their role to configuration provision. They state that roaming considerations are outside RAN2 scope and that the impact of full controllability on UE normal operation has not been evaluated. The position emphasizes that data collection initiation and configuration remain under network control, with the specific determination method still FFS.

InterDigital reports that SA2 did not reach consensus on the feasibility of any of the outlined options (1b, 2, and 3) to meet the RAN requirements specified in LS RP-242389. They state that a full evaluation of potential solutions for all UE side data collection options would require further study in SA2. They emphasize that this study requires coordination with SA5, SA3, and RAN2. Consequently, they ask TSG RAN and TSG SA to take this lack of consensus and the need for further study into account.

InterDigital is advocating for a comprehensive framework that balances MNO control with standardized AI/ML data collection, pushing for solutions that ensure full MNO controllability and visibility while maintaining privacy compliance. They are seeking SA group input to resolve technical feasibility questions rather than taking a strong stance on any particular option.
