Discussion on AI/ML for beam management

      Position extracted by Claude
    

InterDigital supports Option 2 for UE-side model applicability identification, arguing that Option 1 requires excessive configuration overhead for candidate CSI report configurations. They prefer Alt 2 for beam configuration, utilizing a single CSI-ResourceConfigId for both Set A and Set B to minimize specification impacts while supporting scenarios with non-transmitted Set A beams. InterDigital proposes supporting QCL parameter estimation for unmeasured beams via neighboring beams, citing performance data showing Doppler shift errors below 10 Hz and RMS delay spread below 15 ns for 90% of the time. They support UE-assisted performance monitoring (Option 2) and dynamic switching of inference location between UE and network to balance computational load and reporting overhead. Additionally, they propose enhanced reporting for network-sided models, including up to 64 RSRP values and pattern-based reporting mechanisms to reduce overhead without sacrificing prediction accuracy.

      Summary
    

InterDigital presents 29 proposals and 24 observations regarding AI/ML for beam management in NR, focusing on configuration frameworks, reporting overhead reduction, and lifecycle management. The document argues for Option 2 for UE-side model applicability to minimize signaling overhead and supports a unified CSI-ResourceConfigId for both Set A and Set B beams. It further proposes mechanisms for QCL parameter estimation for unmeasured beams, pattern-based reporting, and dynamic switching of inference location between UE and network.

    How this was derived
  

Claude extracted the "position extracted" field above directly from each Tdoc during summarization. For the delta summary at the top, Claude compared InterDigital's consolidated stance at RAN1#119 against their stance at RAN1#118bis and classified the change as new.
