vs RAN1#124
Nokia expanded their contribution scope dramatically to 38 proposals and 30 observations across multiple physical-layer design areas, adopting the Gothia cell concept alongside their existing CA framework for spectrum aggregation. Their positions on ruling out 60 kHz SCS and supporting only normal CP are preserved and hardened with additional detail. The provided summary truncates specifics on frame structure, duplexing, maximum channel bandwidths, and coverage proposals—the status of earlier positions on UE-specific TDD removal, semi-static TDD as primary duplexing, deprioritization of dynamic SBFD/UE SBFD/gNB FD, decoupled serving cell scheduling, and semi-static UL TX switching cannot be confirmed from the available current-meeting text.

Overall aspects of the 6GR multi-antenna system
Position extracted by AI
Nokia proposes ruling out 60 kHz SCS from the Around 15 GHz scenario and postponing final SCS selection between 30 kHz and 120 kHz until end of 2026. They require supporting only normal CP length for TN communication, and for NTN only normal CP in DL with any UL pre-compensation solutions maintaining alignment with NCP symbol structure. For 400MHz UE support with 30 kHz SCS, they require a single RF chain per antenna port with unified processing framework, proposing consideration of asymmetric CBW (200MHz UL / 400MHz DL). They propose studying three frame structure configuration options (symbol-based, layer-based, 2D resource) and require removing UE-specific TDD configuration while supporting flexible symbols as a resource type. They require semi-static TDD as the primary duplexing scheme, propose deprioritizing dynamic SBFD, UE SBFD, and gNB FD, and support dynamic TDD based on predefined TDD patterns rather than NR's symbol-level SFI. For spectrum aggregation, they propose building 6G CA upon a single unified framework with decoupled serving cell scheduling and propose studying semi-static UL TX switching patterns instead of NR's dynamic triggering approach.
Summary
This Tdoc from Nokia presents 24 proposals and 12 observations on 6GR physical layer design aspects including SCS selection, CP length, 400MHz UE bandwidth support, frame structure, duplexing, spectrum aggregation, and coverage, with a focus on system simplification and unified framework design.
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 Nokia's consolidated stance at RAN1#124bis
against their stance at RAN1#124 and classified the change as
