Nokia added a new specification that PDCCH/PDSCH-based paging be supported as the triggered response to DL WUS—no paging response mechanism was specified in the prior contribution. They shifted their connected-mode measurement feasibility argument from a general claim of reduced RRM measurement cost in the 6G EE processing state to a bounded position: EE processing state applicability is limited to SSB-based measurements outside active time, with an explicit technical objection to CSI-RS processing due to computational complexity from multi-port channel matrix estimation and codebook searches. They added residual CFO as a specific risk to EE-based RRM measurement accuracy with a proposal to assume lower residual synchronization error—no CFO concern appeared previously. They dropped prior proposals on early termination of PDCCH skipping and SPS activation/deactivation as WUS-supported features, retaining only ACTIVE times triggering with duration indication and SSSG switching. A new prioritization of RRC IDLE/INACTIVE DL WUS study for IoT appears with no prior counterpart. Their prior specific constraint of one time occasion per paging cycle is preserved within the duty-cycled monitoring stance.

On WUS operation in different RRC states
Position extracted by AI
Nokia proposes that 6GR DL WUS monitoring be duty-cycled with predefined time occasions and that PDCCH/PDSCH-based paging be supported as the triggered response. They argue that using EE processing state for serving and neighbor cell RRM measurements is feasible and significantly increases power saving gains, but they identify large residual CFO as a risk to measurement accuracy and propose assuming lower residual synchronization error. For connected mode, Nokia proposes limiting EE processing state applicability to at least SSB-based measurements outside active time, while questioning its use for CSI-RS processing due to computational complexity from multi-port channel matrix estimation and codebook searches. They require a streamlined 6G PDCCH monitoring adaptation feature suite that avoids functional overlaps seen in 5G (e.g., between Cell-DTX/UE-DRX, DCP/WUS, PDCCH skipping/SSSG switching) and propose studying WUS for triggering ACTIVE times with duration indication and SSSG switching. For IoT, they prioritize RRC IDLE/INACTIVE mode DL WUS study.
Summary
This 3GPP RAN1 document from Nokia presents 16 proposals and 10 observations concerning 6G DL WUS operation across RRC Idle/Inactive and Connected modes, with extensions to IoT. The contribution covers WUS monitoring configuration, EE processing state impacts on measurements, and PDCCH monitoring adaptation features, aiming to establish study assumptions for the 6GR physical layer design.

On WUS operation in different RRC states
Position extracted by AI
Nokia proposes assuming duty-cycled 6GR WUS monitoring with predefined time occasions rather than continuous monitoring, arguing this is necessary to attain UE power benefit given the agreed power model. They propose that WUS monitoring occasions be limited to one time occasion per paging cycle containing one or more continuous WUS monitoring occasions, as increasing monitoring occasions may negatively impact UE power savings. For connected mode, Nokia proposes retaining a basic duty-cycled C-DRX configuration and aligning 6GR WUS monitoring with C-DRX configuration (option 1-1), citing reduced RRM measurement cost in the 6G EE processing state. Nokia proposes studying WUS usage within ACTIVE times (previously deprioritized in NR Rel-19) and extending WUS to support multiple PDCCH monitoring adaptation features including SSSG switching, early termination of PDCCH skipping, and SPS activation/deactivation, while striving to avoid overlapping functionality that occurred in 5G across Cell-DTX, DCP, and LP-WUS.
Summary
This Nokia contribution (18 observations/proposals) discusses WUS operation in RRC states for 6GR power savings. It proposes study assumptions and evaluations for duty-cycled WUS in IDLE/Inactive mode for paging and connected mode for PDCCH monitoring, while also exploring broader WUS use cases like SI indication, PDCCH adaptation, and SPS.
