Title: Summary of RAN1 agreements on LP-WUS/WUR for NR
Document for: Discussion and Decision
|
Conclusion
There is no consensus in RAN1 on whether to introduce any enhancements of PDCCH skipping indication for the interaction with LP-WUS in RRC connected mode in Rel-19.
Agreement
For RRC CONNECTED mode when LP-WUS is configured with Cell DTX, during Cell DTX inactive time, the UE is not expected to monitor LP-WUS both for Option 1-1 and 1-2

Agreement
The case where a UE does NOT supports Rel-17 unified TCI framework but supports LP-WUS is supported in Rel-19. For the TCI state of LP-WUS in RRC CONNECTED mode, select one of the following in RAN1#121 for this case:
Alt1: RRC provides the CORESET ID that UE shall derive the active TCI state for LP-WUS
Alt2: RRC configures K TCI states for LP-WUS and new MAC-CE for TCI activation activates one of them
The case where a UE supports Rel-17 unified TCI framework and supports LP-WUS is supported in Rel-19. For the TCI state of LP-WUS in RRC CONNECTED mode,
When Rel-17 unified TCI framework is configured, LP-WUS follows the activated/indicated TCI-state by MAC-CE/DCI, same as other DL channels/signals (no change to DCI format)
When Rel-17 unified TCI framework is NOT configured, select one of the following in RAN1#121 for this case
Alt1: RRC provides the CORESET ID that UE shall derive the active TCI state for LP-WUS
Alt2: RRC configures K TCI states for LP-WUS and new MAC-CE for TCI activation activates one of them
Same alternative to be chosen for both cases.

Agreement
For LP-WUS monitoring in RRC CONNECTED mode, SSB and/or CSI-RS can be the QCL source of LP-WUS QCL type(s) is {Type A or Type C – for down-selection} and Type D, when applicable

Title: Summary of discussion on RRC parameters for Rel-19 LP-WUS/WUR
Agenda Item: 9.6
Document for: Discussion and Decision

Conclusion
Based on the two round of comments, an further updated version is provided, with the changes relative to R1-2501646 are highliged in blue (updates before RAN1#120bis) and red (updated during RAN1#120bis). Note that the parameters that becomes newly stable during RAN#120bis is marked as “stable” in red in column Q.
