Draft reply on LS on capability reporting for PRS Processing Window
From Samsung
Summary
This document is a Liaison Statement reply from RAN1 to RAN2 regarding capability reporting for Positioning Reference Signal (PRS) Processing Window in Release 19. It contains two specific technical determinations clarifying which network entities must receive specific UE capabilities. The document addresses the distribution of capabilities 58-2-11, 58-2-9, and 58-2-10 between the gNB and the Location Management Function (LMF).
Position
Samsung, representing RAN1, clarifies the distribution requirements for PRS Processing Window capabilities in Release 19. They specify that capability 58-2-11 needs to be informed to the gNB and can be informed to the LMF, establishing a mandatory path to the base station with an optional path to the location server. Furthermore, they determine that capabilities 58-2-9 and 58-2-10 should also be known to the gNB, ensuring the base station has visibility into these specific processing window parameters. This stance resolves ambiguity regarding whether these capabilities are exclusively for the LMF or shared with the gNB.
Key proposals
- Proposal 1 (Sec 1): Capability 58-2-11 must be informed to the gNB and may optionally be informed to the LMF.
- Proposal 2 (Sec 1): Capabilities 58-2-9 and 58-2-10 must be known to the gNB.
