Discussion on consistency of training / inference for AI/ML-based CSI prediction
From Panasonic
Summary
Panasonic presents their view on ensuring consistency between training and inference for AI/ML-based CSI prediction in NR, focusing on UE-side model development and proposing solutions for handling network-side additional conditions. The document contains 1 observation and 6 proposals addressing data collection, configuration identification, and information sharing mechanisms.
Position
Panasonic advocates FOR UE-side only training/development for CSI prediction models and proposes using configuration IDs instead of actual network configurations to preserve proprietary information. They push FOR reusing beam prediction conclusions and implementing data-transfer-based methods, while arguing AGAINST requiring RAN1 to handle data transfer mechanisms to UE-side servers, which should be left to RAN2 and SA working groups.
Key proposals
- Observation 1 (Discussion): Only UE-side training/development is considered for CSI prediction
- Proposal 1 (Discussion): RAN1 should conclude whether NW-side additional condition is necessary or not for ensuring the consistency between training and inference based on the observations and/or evaluation results considering the aspects agreed in RAN1#118bis
- Proposal 2 (Discussion): For ensuring the consistency between training and inference of CSI prediction, the discussion / conclusion in beam prediction can be reused
- Proposal 3 (Discussion): For UE-side data collection, in order to identify the scenario / configuration, how to share the NW-side additional condition should be studied
- Proposal 4 (Discussion): Instead of informing actual configuration, some kind of configuration ID corresponding to associated ID is necessary
- Proposal 5 (Discussion): Data-transfer-based method as not to inform NW-side additional condition at the time of the training should be studied
- Proposal 6 (Discussion): RAN1 is not required to discuss how UE collected data is transferred to UE side (server)
