Discussion on LS on capability reporting for PRS Processing Window
From OPPO
Summary
OPPO provides responses to RAN2 questions regarding capability reporting for PRS Processing Window in the context of AI/ML positioning Case 1. The document contains one main proposal addressing the visibility of specific UE capabilities to the gNB and LMF, aiming to align with legacy positioning procedures.
Position
OPPO proposes that capability 58-2-11, regarding the support of multiple activated PRS processing windows, should be known only to the gNB to maintain alignment with legacy positioning procedures where similar capabilities are gNB-specific. Conversely, OPPO proposes that capabilities 58-2-9 and 58-2-10, which correspond to legacy capabilities 27-3-2 and 27-3-3 respectively, should be known to both the gNB and the LMF. This stance ensures that the LMF is aware of the UE's DL PRS measurement and buffering capabilities outside the Measurement Gap, which is necessary for proper positioning assistance and configuration.
Key proposals
- Proposal 1 (Discussion/Conclusion): Capability 58-2-11 (support of more than one activated PRS processing window) should be known only to the gNB.
- Proposal 1 (Discussion/Conclusion): Capabilities 58-2-9 (DL PRS measurement outside MG) and 58-2-10 (DL PRS buffering capability) should be known to both the gNB and the LMF.
