Summary of Agreements by Topic on UE Power Saving Enhancements

Idle/Inactive Mode UE Power Saving Enhancements

1. Paging Early Indication (PEI):
• PEI without subgrouping can only be implemented by configuring PEI plus UEID subgrouping with one subgroup.
• Multiple PEI occasions for one paging occasion (PO) are not supported.
• UE assistance information for preferred offset between PEI-O and PO is not supported.
• Different PEI configurations for different device types are not supported.
2. TRS/CSI-RS Occasions:
• TRS-ResourceSetConfig IE does not affect UE behavior in CONNECTED mode and can be ignored by UE in CONNECTED mode.
• TRS availability indication field length is determined by the highest value of all indBitID(s) provided by TRS-ResourceSetConfig.
• UE behavior for TRS occasions outside the initial DL BWP is clarified.
3. Corrections to Specifications:
• Editorial corrections to parameter names (e.g., "TRS-ResourceSetConfig" updated to "trs-ResourceSetConfig").
• Clarifications on TRS scrambling IDs and periodicity configurations.

PDCCH Monitoring Adaptation

1. PDCCH Skipping:
• PDCCH skipping applies only during active time and terminates when the UE enters outside active time.
• UE resumes PDCCH monitoring if a positive SR is transmitted or during contention resolution timer, RAR window, or MsgB window.
• UE monitors PDCCH on all serving cells of the corresponding Cell Group when SR is pending.
• PDCCH skipping behavior clarified for scenarios involving RACH transmission due to positive SR.
2. Search Space Set Group Switching:
• Timer value for switching between search space groups is clarified.
• UE behavior for mixed Rel-16 and Rel-17 SSSG switching is aligned.
3. BWP Switching:
• UE resumes PDCCH monitoring on the new active DL BWP after bwp-InactivityTimer expiration during PDCCH skipping duration.
• Behavior clarified for scenarios where PDCCH monitoring adaptation and BWP switching are indicated in the same DCI.

General Agreements

1. Corrections to Specifications:
• Editorial corrections to TS 38.211, TS 38.212, and TS 38.213 for alignment with agreed behaviors and parameter names.
• Clarifications on short message indicators when TRS availability indication is present.
2. LS to RAN2:
• Reply LS to RAN2 on PDCCH skipping behavior endorsed.
3. Final CRs:
• Final CRs for TS 38.211, TS 38.212, and TS 38.213 agreed, incorporating all corrections and clarifications.

This summary consolidates the agreements reached across multiple RAN1 sessions, focusing on idle/inactive mode power saving enhancements, PDCCH monitoring adaptation, and general corrections to specifications.
