Maintenance on Rel-19 AI/ML

      Position extracted by AI
    

InterDigital opposes the current framework where PDSCH rate matching is tied to the configuration of Set A, arguing it introduces unintended restrictions and negates the fundamental benefit of AI/ML beam management by wasting resources on virtual CSI-RS. They propose that rate matching behavior should depend on the presence of the CSI-ResourcePeriodicityAndOffset parameter: if configured, rate matching is performed; if absent, rate matching is not performed. This approach allows the utilization of resource elements for PDSCH transmission when Set A resources are not actually transmitted, thereby preserving resource efficiency. They argue that treating virtual CSI-RS resources identically to transmitted ones causes unnecessary performance degradation and constrains UE implementation flexibility.

      Summary
    

InterDigital argues that mandatory PDSCH rate matching for Set A CSI-RS resources in Rel-19 AI/ML beam management negates the efficiency benefits of the feature and wastes resources when transmissions are virtual. The document presents three observations regarding these inefficiencies and two proposals to condition rate matching on the presence of the CSI-ResourcePeriodicityAndOffset parameter.

    How this was derived
  

The AI extracted the "position extracted" field above directly from each Tdoc during summarization. For the delta summary at the top, the AI compared InterDigital's consolidated stance at RAN1#124bis against their stance at RAN1#124 and classified the change as new. Always verify critical claims against the original Tdocs linked above.
