Agreement:

TP-1 and TP-2 in R1-2104324 for TS36.212 and TS36.213 respectively are endorsed. The changes are to be incorporated by the specification editors of the respective specifications and request the 36.212 and 36.213 spec editors to take the subframeAssignment-r15 to tdm-PatternConfig/tdm-PatternConfigNE-DC change to Rel-15.

R1-2106307 (TS38.214, CR0200, Rel-16, F) 38.214 CR on unaligned frame boundary CA with A-CSI-RS transmission and CSI reference resource definition	Moderator (Nokia), MediaTek

Agreement:

Alignment of the order of SCG and MCG in the section 7.6.2 of TS38.213 as below is endorsed to be included in the 38.213 editor’s alignment CR in thread [105-e-NR-AlignmentCRs-38213]

Agreement:

Adopt the following text in 38.214 5.2.1.5.1 “Aperiodic CSI Reporting/Aperiodic CSI-RS when the triggering PDCCH and the CSI-RS have the same numerology”:

The aperiodic CSI-RS is transmitted in a slot , , if UE is configured with ca-SlotOffset for at least one of the triggered and triggering cell, and in slot , otherwise, and where

-	n is the slot containing the triggering DCI, X is the CSI-RS triggering offset according to the higher layer parameter aperiodicTriggeringOffset or aperiodicTriggeringOffset-r16,

-	and are the and the which are determined by higher-layer configured ca-SlotOffset for the cell receiving the PDCCH, and are the and the which are determined by higher-layer configured ca-SlotOffset for the cell transmitting the CSI-RS respectively, as defined in [4, TS 38.211] clause 4.5.

Agreement:

Adopt the following text in 38.214 5.2.2.5 “CSI reference resource definition”:

In the time domain, the CSI reference resource for a CSI reporting in uplink slot n’ is defined by a single downlink slot n-nCSI_ref,

-	where and and are the subcarrier spacing configurations for DL and UL, respectively, and the and the are determined by higher-layer configured ca-SlotOffset for the cells transmitting the uplink and downlink, as defined in clause 4.5 of [4, TS 38.211]

Agreement:

Correction of the subscript when referencing the SCS of a PDSCH in the section 5.5 of TS38.214 as below is endorsed to be included in the 38.214 editor’s alignment CR in thread [105-e-NR-AlignmentCRs-38214].

This clause applies only if the PDCCH carrying the scheduling DCI is received on one carrier with one OFDM subcarrier spacing (µPDCCH), and the PDSCH scheduled to be received by the DCI is on another carrier with another OFDM subcarrier spacing (µPDSCH).
