Extensive Summary of Agreements by Topic

SRS Carrier Switching

• Simultaneous SRS Carrier Switching: Two SRS carrier switches are considered simultaneous if their transmissions overlap in time. UE capability signaling is reused, and UEs not capable of simultaneous switching are not expected to be configured for it.
• Switching Time: Required switching time depends on UE capability and operation state. Prioritization rules in TS 38.214 Sec. 6.2.1.3 are applied, and no spec change is needed.

HARQ Process Numbers

• Maximum HARQ Processes: Support up to 32 HARQ process numbers for TN in FR1 and FR2-1 in Rel-19.
• New RRC Parameters: Introduced parameters for HARQ process numbers (e.g., harq-ProcessNumberSizeDCI-0-1-Ext-r19) with specific value ranges.
• Layer Configuration: Parameters can only be configured when the maximum number of layers for PDSCH/PUSCH is up to 4.

UE Capabilities

• CSI-RS Reception: Define a new UE capability to count CSI-RS ports within one resource as a single resource, even if referred by multiple report settings.
• SRS Frequency Hopping: Extend Rel-18’s UL frequency hopping for positioning to non-RedCap UEs in a single carrier. UE capability for this feature is introduced.
• PDCCH Monitoring: Introduce UE capability and RRC parameters to enable/disable monitoring based on designated SSSG index.

SRS Beamforming and Antenna Switching

• Enhancement of SRS Beamforming: Improvements for FR2 positioning were discussed, including antenna switching pattern reporting.
• SRS Frequency Hopping: UEs are expected to perform frequency hopping for positioning based on higher layer parameters, subject to UE capability.

Link Adaptation

• Enhancements: Proposals for improving link adaptation were discussed, including handling ambiguities with SRS carrier switching.

MBMS Support

• Cell Acquisition Signals: Non-MBSFN subframes containing acquisition signals in MBMS-dedicated cells are transmitted within specific time intervals. New parameters (n and k) are introduced for configuration.

UL Frequency Hopping

• Non-RedCap UEs: Extend UL frequency hopping for positioning to non-RedCap UEs. Liaison sent to RAN2 to discuss potential new parameters.

Concurrent Configuration of SRS-CS and UL Tx Switching

• Prioritization Rules: Confirm prioritization rules between target and source CCs, with no spec change needed.
• Switching Time: Switching time depends on UE capability and operation state, with specific rules for simultaneous transmission.

Counting of Active NZP-CSI-RS Resources

• Proposal: Counting of active NZP-CSI-RS resources was discussed, involving multiple stakeholders (e.g., Nokia, Apple, Ericsson).

CDM DMRS Port Allocation

• Enhancements: Improvements in DMRS port allocation combinations for enhanced uplink and downlink performance were proposed.

Miscellaneous

• UE Frequency Hopping for Positioning: Extend Rel-18’s UL frequency hopping for positioning transmission to non-RedCap UEs.
• Muting of Always-On Signals: Proposal for muting always-on signals for 5G Broadcast was discussed.
