Summary of Agreements by Topic

UE Feedback Enhancements for HARQ-ACK

• PUCCH repetition and dynamic PUCCH carrier switching are clarified, with SPS HARQ-ACK always transmitted on PCell/PSCell/PUCCH-SCell.
• Semi-static PUCCH cell switching applies only to non-repeated PUCCH transmissions, with timing clarified for SCell activation/deactivation/dormancy.
• Enhanced Type 3 HARQ-ACK codebook construction includes per cell and per HARQ process configuration, with separate DCI field presence for DCI format 1_2.
• One-shot HARQ-ACK retransmission is supported before and after the initial PUCCH transmission slot, handled per physical layer priority.
• Deferred SPS HARQ-ACK bits are appended to the HARQ-ACK codebook in the target slot, with timelines clarified for dropping deferred SPS HARQ.

Intra-UE Multiplexing/Prioritization

• LP PUCCH overlapping with HP PUCCH is dropped if overlapping PUCCH is subject to repetition.
• LP HARQ-ACK is multiplexed with HP HARQ-ACK on PUCCH or PUSCH, while LP CSI/SR are dropped during multiplexing.
• Power allocation rules prioritize LP and HP PUSCH with HARQ-ACK equally, with HP PUSCH without UCI having the same priority as HP PUSCH with LP HARQ-ACK.
• Simultaneous PUCCH/PUSCH transmission excludes overlapping channels for multiplexing.

Propagation Delay Compensation Enhancements

• RTT-based propagation delay compensation is supported for Rel-17, with PRS used only in RRC_CONNECTED mode.
• A new spatial relation field ("spatialRelationInfo-PDC-r17") indicates spatial relation between reference RS and target SRS.
• PRS configuration aligns subcarrier spacing and cyclic prefix with the downlink active BWP of the serving cell, with UE not measuring DL PRS outside the active BWP.

Unlicensed Band URLLC/IIoT

• Semi-static channel access mode ensures consistent COT ownership for all transmissions in a burst, with UL transmission allowed for contention-free random access.
• PUSCH repetition Type B is supported for DG on unlicensed spectrum in Rel-17.

PUCCH Transmission and Power Control

• Adjustments were made to PUCCH power control, including multiplexing HARQ-ACK of different priorities and inter-priority UCI multiplexing.

Semi-Static Channel Access and PUCCH Switching

• Corrections were made to semi-static channel occupancy and PUCCH carrier switching to improve alignment and functionality.

General Agreements

• Editorial changes improve clarity in specifications for HARQ-ACK feedback, intra-UE multiplexing, and propagation delay compensation.
• Unsupported features include simultaneous configuration of Rel-17 intra-UE multiplexing and SPS HARQ deferral, as well as simultaneous configuration of semi-static and dynamic PUCCH cell switching.

Miscellaneous Corrections

• Various corrections enhance Rel-17 URLLC/IIoT specifications, including definitions of DCI and alignment of RRC parameters.
