vs RAN1#124
Ericsson is a new contributor to this topic at RAN1_124bis. They introduce a requirement to avoid overlapping functionalities like PEI and Rel-19 WUS, proposing a single DL WUS tool per RRC state—a structural constraint absent from prior meeting discussions. They present a novel technical case for full measurement offloading (serving cell RRM, RLM/BFD, and neighboring cell RRM) to the EE processing state, quantified with 60%-90% energy saving gain. They provide the first meeting contribution with specific RSRP accuracy evaluation data tied to RX count and CFO assumptions (2dB accuracy with 2Rx/3 SSBs/160ms periodicity; failure with 1Rx at 5ppm CFO). Their argument that entry/exit conditions for WUS monitoring are unnecessary in Idle/Inactive because 6G WUS targets full cell coverage is a new technical position with no prior counterpart.

WUS operation in RRC states
Position extracted by AI
Ericsson proposes studying a single 6G DL WUS tool for paging indication in Idle/Inactive state and a single WUS feature for PDCCH monitoring indication in Connected state, explicitly requiring the avoidance of overlapping functionalities like PEI and Rel-19 WUS. They argue entry/exit conditions for WUS monitoring are unnecessary in Idle/Inactive states because 6G WUS targets full cell coverage. They present a technical case for offloading serving cell RRM and RLM/BFD measurements, as well as neighboring cell RRM measurements, to EE processing state in RRC connected state, supported by energy saving evaluations showing full offloading provides 60%-90% gain. Their preliminary results indicate EE processing RSRP accuracy of 2dB using 3 SSBs with 160ms periodicity is achievable with 2Rx but may not be achieved with 1Rx under 5ppm CFO, requiring smaller CFO values for the 1Rx case.
Summary
Ericsson presents 7 proposals and 7 observations on 6G WUS operation across RRC states, focusing on UE energy saving via a single WUS tool per state, full cell coverage for idle mode, and offloading RRM/RLM/BFD measurements to energy-efficient (EE) processing. They support studying EE processing measurement accuracy with preliminary results showing RSRP accuracy targets are achievable with 2Rx or smaller CFO values.
