Title:	Discussion on Reply LS on collision between SSB and RA occasion for LTM
Document for:		Discussion and Decision
Conclusion
In this contribution, we provide our views on the potential RAN1 actions based on the RAN4 reply on collision between SSB and RA occasion for LTM. The following proposals have been made:
Proposal 1: For RAN1, it should be sufficient to specify that RACH shall be prioritized over SSB if the collision occurs outside of the MG in TS 38.213.
Proposal 2: RAN1 should inform RAN2 about this reply from RAN4 for any potential RAN2 specification impact.

Title: 	Discussion on differentiation of sDCI mTRP, mDCI mTRP and sTRP
Document for:	Discussion and Decision
Conclusion
Proposal. To RAN2, RAN1 can provide the following answers.
Question 2a: RAN2 would like to ask if RAN1 has any concern on the above highlight sentence?
Answer 2a: RAN1 has a concern on the above highlight sentence, because the RRC parameter applyIndicatedTCI-State in ControlResourceSet is optionally present and may not be mandatorily configured for all ControlResourceSets in all BWPs of the serving cell operated as sDCI mTRP, hence it cannot clearly distinguish between sDCI mTRP and sTRP.
Question 2b: If there is any concern on Question 2a, what’s RAN1’s suggestion on how to separate the cells operated as sTRP and sDCI mTRP?
Answer 2b: As mentioned in Answer 2a, the RRC parameter applyIndicatedTCI-State cannot clearly distinguish between sDCI mTRP and sTRP. Instead, it is possible to use all RRC parameters for supporting sDCI mTRP (i.e., relevant RRC parameters for TCI application as well as DL/UL multi-TRP schemes). It is RAN1 consensus that RRC parameter(s) is used to indicate whether a serving cell is in sDCI mTRP operation or sTRP operation. For each serving cell list, the network ensures that either at least one of the following RRC parameters is configured for all BWPs of all serving cells (i.e., the case of single-DCI based multi-TRP) or none of the following RRC parameters is configured in any BWP of any serving cell (i.e., single-TRP).
“applyIndicatedTCI-State-r18” in ConfiguredGrantConfig, ControlResourceSet, PUSCH-Config, SRS-ResourceSet, PDCCH-ConfigCommon, PUCCH-ResourceExt-v1610, or

Title:	Discussion for HARQ-ACK aspects of Rel-17 multi-PDSCH scheduling
Document for:	Discussion and decision
Conclusions
This contribution considered the issue of counting overlapping DCIs / PDCCHs as related to HARQ-ACK information for multi-PDSCH scheduling, and made the following proposal.
Proposal: Clarify that, when a UE receives multiple DCI formats in a same PDCCH MO, and at least one of the DCI formats schedules multiple PDSCHs on a same serving cell, the UE counts (and runs the Type-2 HARQ-ACK pseudo-code for) the serving cell a same number of times as the number of DCI formats – and not the number of scheduled PDSCH receptions.
Adopt the TP proposed in draft CR [1].

Title:	Semi-Persistent SRS Frequency Hopping Discussion 
Agenda item:	7
Document for:	Discussion and Decision
Conclusions
In this paper we make the following observations and proposals: 
Observation 1: As the positioning SRS frequency hopping configuration is outside of the legacy BWP configuration it is not associated with any BWP ID.  
Observation 2: The SP positioning SRS MAC CE uses Cell ID, BWP ID, and SRS resource set ID to indicate to the UE which SRS resource set is impacted by the MAC CE.
Proposal 1: RAN1 to conclude that the existing MAC CE is not able to trigger SP positioning SRS frequency hopping. 
Proposal 2: RAN1 to select one of the following options for enabling SP positioning SRS frequency hopping and send an LS to RAN2 with the outcome to check the feasibility:
Option 1: Introduce a new MAC CE specifically for activating/deactivating positioning SRS frequency hopping.
Option 2: Repurpose an existing field in the current SP positioning SRS MAC CE to indicate that the MAC CE is for activation/deactivating positioning SRS frequency hopping

Title:	Discussion on suspending the RRC connection for SDT
Document for:	Discussion and decision
Conclusion
The observations captured are the following: 
Observation 1.	TS 38.213 §19 captures “UE indicated to release a dedicated RRC connection” which would refer to the case which transitions to the UE into RRC_IDLE (as per TS 38.331 §5.3.8.1). This operation in TS 38.213 §19 is not aligned to TS 38.331 and the corresponding Rel-17 SDT WID for which the RRC state of the UE is limited only to RRC_INACTIVE.
Observation 2.	TS 38.331 defines two behaviours (and terminologies): (1) to release the RRC connection when the UE in RRC_CONNECTED receives the RRCRelease message without the suspendConfig IE (which transitions the UE into RRC_IDLE), and (2) to suspend the RRC connection when the UE in RRC_CONNECTED receives the RRCRelease message with the suspendConfig IE (which transitions the UE into RRC_INACTIVE).

The proposals captured are the following: 
Proposal 1.	To correct the inconsistency in RAN1 TS 38.213 for Small Data Transmission (SDT) functionality based on the intended behaviour of the RRC connection defined by RAN2 in TS 38.331 and for this, to agree on the draftCRs R1-2503745/R1-2503746 for Rel-17 and Rel-18 (with TPs of TS 38.213 in §19 “PUSCH transmission in RRC_INACTIVE state”).

Title:              	Discussion on starting slot for typeII Doppler CSI
Document for:	Discussion and Decision

Conclusion
In this contribution, we provided our views on the definition of starting slot for predicted CSI, and we propose:
Observation: For typeII Doppler CSI, it’s unclear for the slot  and the predictiondelay , there are two options for clarification:
Option 1: slot  is a downlink slot, and the predictiondelay  corresponds to downlink subcarrier spacing.
Option 2: slot  is an uplink slot, and the predictiondelay  corresponds to uplink subcarrier spacing, at least for .  
Proposal 1: UE behavior should be defined in case of reported DO value is ‘out of range’ (i.e. an infinite interval ). For example, the UE can do no pre-compensation or UE can do pre-compensation based on an exact value . 
Proposal 2: For typeII Doppler CSI, clarifying that:
The earliest of the  slot intervals starts at slot , where  corresponds to subcarrier spacing configuration for DL,
  and  and  are the subcarrier spacing configurations for DL and UL, respectively, and  and  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],
 is the uplink slot in which the CSI is reported.
And adopt the following CR.

Title: On R17 SSSG reset with BWP switch triggered by RA procedure
Document for: Discussion and decision
Conclusion
We have the following proposals for R17 UE power saving with BWP switch triggered by RA procedure:

Proposal 1: RAN 1 to clarify whether UE should reset the PDCCH monitoring due to BWP switch triggered by the RA procedure according to Clause 10.4 of TS 38.213 (as copied below in Proposal 2) for R17 UE power saving.

Proposal 2: To accommodate more general BWP switch cases triggered by higher layers (including BWP switch triggered by the RA procedure), adopt the following revision in TS 38.213.

Observation 1: During the online discussion in RAN1 #120, some companies have doubts on whether initialDownlinkBWP can be configured with multiple search space set groups (SSSGs). To address this, Figure 1 shows the search space switching configurations under initialDownlinkBWP from 38.331. It can be seen that initialDownlinkBWP can be configured with multiple SSSGs.

Interpretation 1
For receiving PDSCH in FR1, when applying beam determination procedure in TS 38.214, UE determines timeDurationForQCL in FR1 as 0;
Interpretation 2
For receiving PDSCH in FR1, when applying beam determination procedure in TS 38.214, the condition with timeDurationForQCL is not applicable to FR1,
Note: This means that UE performs beam determination procedure for FR1 by ignoring the condition with timeDurationForQCL.

Title:                     On TCI-state determination with BWP Switching operation
Agenda item:	7
Document for:	Discussion and Decision
1 
Conclusion 
In this contribution, we discussed an ambigurity relation to TCI-state determination for BWP switching operation. Based on the discussion, we present the following observations and proposals:   
Observation #1: TS 38.133 and TS 38.214 define different rules for determining the TCI-state of a target BWP after a BWP switch, before a TCI-state activation MAC-CE is received for that BWP.

Observation #2: The default QCL rule in TS 38.214 was orginally intended for the period after initial access and before TCI-state are configured by RRC and/or MAC-CE, not for handling BWP switching scenario.

Proposal #1: RAN1 to confirm that the following rule from TS 38.133 is used to determine the TCI-state for a new BWP after a BWP switch: 
‘Provided the UE does not have the required TCI-state information to receive PDCCH and PDSCH in the new BWP, the UE shall use old TCI-states before the BWP switch until a new MAC CE updating the required TCI-state information for PDCCH and PDSCH is received after the BWP switch’. 

Proposal #2: RAN1 to endorse the following CR to TS 38.214 to resolve the identified ambigurity:

Title:	Discussions on AP CSI-RS active time for CSI report configured with ‘none’
Agenda Item:	7
Document for:	Discussion and Decision
Conclusion
In this contribution, we have discussed our views on remaining issues for AP CSI-RS active time and make the following proposals:
Proposal 1: For earlier releases (Rel-15 to Rel-17), draw a conclusion that active time of aperiodic CSI-RS starts from the end of the PDCCH containing the request and ends at the end of the scheduled PUSCH containing the report associated with this aperiodic CSI-RS, if any.
Proposal 2: For Rel-18 NR, adopt the 1st change in R1-2504449.
Proposal 3: For earlier releases (Rel-15 to Rel-17), draw a conclusion that if ‘UL-SCH’ field is set to ‘0’ and the associated reportQuantity in the CSI report indicated by the ‘CSI request’ field is set to ‘none’, active time of aperiodic CSI-RS starts from the end of the PDCCH containing the request and ends at the last symbol between  symbols after the first symbol after the PDCCH and  symbols after the last symbol of the CSI-RS.
Proposal 4: For Rel-18 NR, adopt the 2nd change in R1-2504449.

Title:	Discussion on aperiodic triggering offset of CSI-IM for Rel-18 type II Doppler codebook and Rel-18 type II Doppler port selection codebook
Agenda Item:	7
Document for:	Discussion and Decision

Conclusion
In this contribution, we provide our views on aperiodic triggering offset of CSI-IM for Rel-18 type II Doppler codebook. The following proposal is made:
Proposal 1: For the Rel-18 Type-II Doppler codebook and Rel-18 type II Doppler port selection codebook, the aperiodic triggering offset of the CSI-IM, if configured, follows the offset of the associated NZP CSI-RS resource with the lowest resource ID in the CSI-RS resource set for channel measurement.

Title:	Discussion on CSI-RS resource slot offsets for the Rel-18 Type-II codebook refinement for CJT mTRP
Agenda Item:	7
Document for:	Discussion and Decision

Conclusion
In this contribution, slot offsets of CSI-RS resources for the Rel-18 Type-II codebook refinement for CJT mTRP are discussed. Based on the discussion, we have the following proposals:
Proposal 1: For the Rel-18 Type-II codebook refinement for CJT mTRP, each of the  aperiodic CSI-RS resources can be configured by a higher layer parameter (e.g., additionalOneSlotOffset) with one additional slot offset relative to the slot offset configured by the higher layer parameter aperiodicTriggeringOffset in the resource set.
Proposal 2: Send an LS to RAN2 to ask for adding a new RRC parameter in aperiodicTriggeringOffset to indicate the slot offsets for each of the  aperiodic CSI-RS resources.

Title:	Clarification on the starting MO of PEI-O
Document for:	Discussion and Decision 

Conclusions
This contribution discusses the clarification with respect to the determination of the starting MO of PEI occasion. The following is proposed for clarification.
Proposal 1: RAN1 to clarify which alternative should be used for determination of the starting MO of PEI-O:
Alt.1: UE does not expect a configuration of firstPDCCH-MonitoringOccasionOfPEI-O indicating a MO which overlaps with uplink symbol or not aligned with the MO pattern configured by pei-SearchSpace;
Alt.2: If a configuration of firstPDCCH-MonitoringOccasionOfPEI-O indicating a MO which overlaps with uplink symbol or not aligned with the MO pattern configured by pei-SearchSpace, the first PDCCH monitoring occasion for DCI format 2_7 is the first MO configured by pei-SearchSpace which is not overlapped with uplink symbol after the symbol indicated by firstPDCCH-MonitoringOccasionOfPEI-O.

Conclusion
Based on the comments received, this CR is only for Rel-17 and no mirror CR for Rel-18 in this meeting. Rel-18 CR can be discussed in future meeting.
For Rel-17 CR, there are two possible ways to address this issue.
Alt1: TP is revised based on option1
If a UE is provided a zero value for searchSpaceID in PDCCH-ConfigCommon for a Type0/0A/1A/2-PDCCH CSS set, the UE determines monitoring occasions for PDCCH candidates of the Type0/0A/1A/2-PDCCH CSS set as described in clause 13, and the UE is provided a C-RNTI, the UE monitors PDCCH candidates only at monitoring occasions associated with a SS/PBCH block, where the SS/PBCH block is determined by the most recent of 
-	an indicated TCI-State of the active BWP that includes a CORESET with index 0 provided with followUnifiedTCI-State, as described in [6, TS 38.214], which includes a CSI-RS quasi-co-located with the SS/PBCH block if the UE is provided followUnifiedTCI-State for the CORESET with index 0; otherwise, a MAC CE activation command indicating a TCI state of the active BWP that includes a CORESET with index 0, as described in [6, TS 38.214], where the TCI-state includes a CSI-RS which is quasi-co-located with the SS/PBCH block, or 
-	a random access procedure that is not initiated by a PDCCH order that triggers a contention-free random access procedure, or
-	configured-grant based PUSCH transmission in RRC_INACTIVE state as described in clause 19.

Alt2:

Title:              	Summary on draft CR discussion for group based beam reporting 
Document for:	Discussion and Decision

Conclusion
According to companies’ input, the following is proposed.
Proposal 1: For the missing parameter to provide the number of reported resource groups for Rel-18 group based beam reporting, down-select one of the following direction
Direction 1a [1]: Send LS to RAN2 to ask for adding nrofReportedGroups-r18 in groupBasedBeamReporting-v1800, 
FFS: clarification that groupBasedBeamReporting-v1710 and groupBasedBeamReporting-v1800 cannot be configured simultaneously
Direction 1b [5]: Change RRC parameter “nrofReportedGroups-r18” in TS 38.214 to “nrofReportedGroups-r17”. And send LS to RAN2 to ask for clarification that groupBasedBeamReporting-v1800 must be dependent on groupBasedBeamReporting-v1710 configuration and the UE assumption when both groupBasedBeamReporting-v1710 and groupBasedBeamReporting-v1800 are configured.

Proposal 2: Further discuss whether the changes are needed for correcting the conditions for group based beam reporting.
Conditions to enable Rel-15, Rel-17 and Rel-18 group based beam reporting need to be clarified
According to TS 38.331, when groupBasedBeamReporting (without suffix) set to 'enabled', it may suggest either Rel-15 group based beam reporting or Rel-17 group based beam reporting or Rel-18 group based beam reporting. Thus, for UE to adopt Rel-15 group based beam reporting, it shall not be configured with groupBasedBeamReporting-v1710 nor groupBasedBeamReporting-v1800, meanwhile, for UE to adopt Rel-18 group based beam reporting, groupBasedBeamReporting (without suffix) shall set to 'enabled' and groupBasedBeamReporting-v1800 shall be configured.

Proposal 3: Adopt the following changes for Rel-17 group based beam reporting.

Proposal 4: Adopt the following changes for Rel-18 group based beam reporting.

Title:	Summary on discussion on SP SRS frequency hopping support 
Agenda Item:	7
Document for:	Discussion and Decision
Conclusion
Proposals for Tuesday Morning Online discussion:

Proposal 1:
Option 1: Send an LS to RAN2 highlighting the issue of activation/deactivation of SP SRS frequency hopping and ask them to fix it if they confirm the issue. 
Option 2: Continue discussion on a particular solution and send an LS to RAN2 with an endorsed solution from RAN1 point of view. 

Proposal 2: 
Option 1: Agree that when positioning SRS FH is configured to the UE in a CC that the UE can’t be configured with other positioning SRS in that CC. 
Option 2: Conclude that when positioning SRS FH is configured to the UE in a CC that the UE can be configured with other positioning SRS in that CC. 

Potential solutions discussed in RAN1: 
Option 1: Introduce a new MAC CE specifically for activating/deactivating positioning SRS frequency hopping.
Supported by: Ofinno 
Option 2: Repurpose an existing field in the current SP positioning SRS MAC CE to indicate that the MAC CE is for activation/deactivating positioning SRS frequency hopping 
Supported by: vivo, Nokia, Ofinno 
Option 3: When the UE is configured with positioning SRS frequency hopping the UE ignores the BWP ID field in the MAC CE. 
Note: this implies that for a CC, the UE can’t be configured with other positioning SRS (e.g., in a “regular” BWP) in the CC when it is configured with positioning SRS frequency hopping in the CC. 
Supported by: QC, vivo, ZTE

5.2.1.4.2	Report quantity configurations

If the UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity set to 'cri-RSRP', 'ssb-Index-RSRP', 'cri-RSRP- Index' or 'ssb-Index-RSRP- Index',
-	if the UE is configured with the higher layer parameter groupBasedBeamReporting set to 'disabled', the UE is not required to update measurements for more than 64 CSI-RS and/or SSB resources, and the UE shall report in a single report nrofReportedRS (higher layer configured) different CRI or SSBRI for each report setting.

5.2.1.2	Resource settings

The time domain behavior of the CSI-RS resources within a CSI Resource Setting are indicated by the higher layer parameter resourceType and can be set to aperiodic, periodic, or semi-persistent. For periodic and semi-persistent CSI Resource Settings, when the UE is configured with groupBasedBeamReporting-or groupBasedBeamReporting-, the number of CSI Resource Sets configured is S=2, otherwise the number of CSI-RS Resource Sets configured is limited to S=1, except for periodic CSI Resource Settings, when the UE is configured with TDCP reporting, for which the number of CSI-RS Resource Sets in the CSI Resource Setting for channel measurement is  and all the CSI-RS Resource Sets are configured with the higher layer parameter trs-Info. For periodic and semi-persistent CSI Resource Settings, the configured periodicity and slot offset is given in the numerology of its associated DL BWP, as given by BWP-id. When a UE is configured with multiple CSI-ResourceConfigs consisting the same NZP CSI-RS resource ID, the same time domain behavior shall be configured for the CSI-ResourceConfigs. When a UE is configured with multiple CSI-ResourceConfigs consisting the same CSI-IM resource ID, the same time-domain behavior shall be configured for the CSI-ResourceConfigs. All CSI Resource Settings linked to a CSI Report Setting shall have the same time domain behavior.


5.2.1.4.1	Resource Setting configuration

For aperiodic CSI, each trigger state configured using the higher layer parameter CSI-AperiodicTriggerState is associated with one or multiple CSI-ReportConfig where the CSI-ReportConfig not configured with groupBasedBeamReporting-or groupBasedBeamReporting- is linked to periodic, or semi-persistent, or aperiodic resource setting(s): 
-	When one Resource Setting is configured, the Resource Setting (given by higher layer parameter resourcesForChannelMeasurement) is for channel measurement for L1-RSRP or for channel and interference measurement for L1-SINR computation.
-	When two Resource Settings are configured, the first one Resource Setting (given by higher layer parameter resourcesForChannelMeasurement) is for channel measurement and the second one (given by either higher layer parameter csi-IM-ResourcesForInterference or higher layer parameter nzp-CSI-RS-ResourcesForInterference) is for interference measurement performed on CSI-IM or on NZP CSI-RS.
-	When three Resource Settings are configured, the first Resource Setting (higher layer parameter resourcesForChannelMeasurement) is for channel measurement, the second one (given by higher layer parameter csi-IM-ResourcesForInterference) is for CSI-IM based interference measurement and the third one (given by higher layer parameter nzp-CSI-RS-ResourcesForInterference) is for NZP CSI-RS based interference measurement.
For aperiodic CSI, and for periodic and semi-persistent CSI resource settings, each trigger state configured using the higher layer parameter CSI-AperiodicTriggerState is associated with one or multiple CSI-ReportConfig where the CSI-ReportConfig configured with groupBasedBeamReporting-or groupBasedBeamReporting- is linked to periodic or semi-persistent, setting(s): 
-	When one Resource Setting is configured, the Resource setting is given by resourcesForChannelMeasurement for L1-RSRP measurement. In such a case, the number of configured CSI Resource Sets in the Resource Setting is S=2
For aperiodic CSI, and for aperiodic CSI resource settings, each trigger state configured using the higher layer parameter CSI-AperiodicTriggerState is associated with one or multiple CSI-ReportConfig where the CSI-ReportConfig configured with groupBasedBeamReporting-or groupBasedBeamReporting-is associated with resourcesForChannel and resourcesForChannel2, which correspond to first and second resource sets, respectively, for L1-RSRP measurement.

5.2.1.4.3	L1-RSRP Reporting

For L1-RSRP reporting, if the higher layer parameter nrofReportedRS in CSI-ReportConfig is configured to be one, or if the higher layer parameters nrOfReportedCells and nrOfReportedRS-PerCell are both configured to be one, the reported L1-RSRP value is defined by a 7-bit value in the range [-140, -44] dBm with 1dB step size, if the higher layer parameter nrofReportedRS is configured to be larger than one, or if the higher layer parameter groupBasedBeamReporting is configured as 'enabled', or if the higher layer parameter groupBasedBeamReporting-is configured, or if the higher layer parameter groupBasedBeamReporting-is configured, or if any of the higher layer parameters nrOfReportedCells and nrOfReportedRS-PerCell is configured to be larger than one, the UE shall use differential L1-RSRP based reporting, where the largest measured value of L1-RSRP is quantized to a 7-bit value in the range [-140, -44] dBm with 1dB step size, and the differential L1-RSRP is quantized to a 4-bit value. The differential L1-RSRP value is computed with 2 dB step size with a reference to the largest measured L1-RSRP value which is part of the same L1-RSRP reporting instance. The mapping between the reported L1-RSRP value and the measured quantity is described in [11, TS 38.133]. 
When the higher layer parameter groupBasedBeamReporting-or the higher layer parameter groupBasedBeamReporting- in CSI-ReportConfig is configured, the UE shall indicate the CSI Resource Set associated with the largest measured value of L1-RSRP, and for each group, CRI or SSBRI of the indicated CSI Resource Set is present first.



Rel-17 TP
Proposal 2: Adopt the following changes for Rel-17 group based beam reporting. 
5.2.1.4.2	Report Quantity Configurations

If the UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity set to 'cri-RSRP', 'ssb-Index-RSRP', 'cri-RSRP- Index' or 'ssb-Index-RSRP- Index',
-	if the UE is configured with the higher layer parameter groupBasedBeamReporting set to 'disabled', the UE is not required to update measurements for more than 64 CSI-RS and/or SSB resources, and the UE shall report in a single report nrofReportedRS (higher layer configured) different CRI or SSBRI for each report setting. 
-	if the UE is configured with the higher layer parameter groupBasedBeamReporting set to 'enabled', the UE is not required to update measurements for more than 64 CSI-RS and/or SSB resources, and the UE shall report in a single reporting instance two different CRI or SSBRI for each report setting, where CSI-RS and/or SSB resources can be received simultaneously by the UE either with a single spatial domain receive filter, or with multiple simultaneous spatial domain receive filters.

5.2.1.2	Resource settings

The time domain behavior of the CSI-RS resources within a CSI Resource Setting are indicated by the higher layer parameter resourceType and can be set to aperiodic, periodic, or semi-persistent. For periodic and semi-persistent CSI Resource Settings, when the UE is configured with groupBasedBeamReporting-, the number of CSI Resource Sets configured is S=2, otherwise the number of CSI-RS Resource Sets configured is limited to S=1. For periodic and semi-persistent CSI Resource Settings, the configured periodicity and slot offset is given in the numerology of its associated DL BWP, as given by BWP-id. When a UE is configured with multiple CSI-ResourceConfigs consisting the same NZP CSI-RS resource ID, the same time domain behavior shall be configured for the CSI-ResourceConfigs. When a UE is configured with multiple CSI-ResourceConfigs consisting the same CSI-IM resource ID, the same time-domain behavior shall be configured for the CSI-ResourceConfigs. All CSI Resource Settings linked to a CSI Report Setting shall have the same time domain behavior.



5.2.1.4.1	Resource Setting configuration

For aperiodic CSI, each trigger state configured using the higher layer parameter CSI-AperiodicTriggerState is associated with one or multiple CSI-ReportConfig where the CSI-ReportConfig not configured with groupBasedBeamReporting- is linked to periodic, or semi-persistent, or aperiodic resource setting(s): 
-	When one Resource Setting is configured, the Resource Setting (given by higher layer parameter resourcesForChannelMeasurement) is for channel measurement for L1-RSRP or for channel and interference measurement for L1-SINR computation.
-	When two Resource Settings are configured, the first one Resource Setting (given by higher layer parameter resourcesForChannelMeasurement) is for channel measurement and the second one (given by either higher layer parameter csi-IM-ResourcesForInterference or higher layer parameter nzp-CSI-RS-ResourcesForInterference) is for interference measurement performed on CSI-IM or on NZP CSI-RS.
-	When three Resource Settings are configured, the first Resource Setting (higher layer parameter resourcesForChannelMeasurement) is for channel measurement, the second one (given by higher layer parameter csi-IM-ResourcesForInterference) is for CSI-IM based interference measurement and the third one (given by higher layer parameter nzp-CSI-RS-ResourcesForInterference) is for NZP CSI-RS based interference measurement.

-	When one Resource Setting is configured, the Resource setting is given by resourcesForChannelMeasurement for L1-RSRP measurement. In such a case, the number of configured CSI Resource Sets in the Resource Setting is S=2
For aperiodic CSI, and for aperiodic CSI resource settings, each trigger state configured using the higher layer parameter CSI-AperiodicTriggerState is associated with one or multiple CSI-ReportConfig where the CSI-ReportConfig configured with groupBasedBeamReporting- is associated with resourcesForChannel and resourcesForChannel2, which correspond to first and second resource sets, respectively, for L1-RSRP measurement.
For semi-persistent or periodic CSI, each CSI-ReportConfig is linked to periodic or semi-persistent Resource Setting(s):
-	When one Resource Setting (given by higher layer parameter resourcesForChannelMeasurement) is configured, the Resource Setting is for channel measurement for L1-RSRP or for channel and interference measurement for L1-SINR computation.
-	When two Resource Settings are configured, the first Resource Setting (given by higher layer parameter resourcesForChannelMeasurement) is for channel measurement and the second Resource Setting (given by higher layer parameter csi-IM-ResourcesForInterference) is used for interference measurement performed on CSI-IM. For L1-SINR computation, the second Resource Setting (given by higher layer parameter csi-IM-ResourcesForInterference or higher layer parameter nzp-CSI-RS-ResourceForInterference) is used for interference measurement performed on CSI-IM or on NZP CSI-RS.


5.2.1.4.3	L1-RSRP Reporting

For L1-RSRP reporting, if the higher layer parameter nrofReportedRS in CSI-ReportConfig is configured to be one, the reported L1-RSRP value is defined by a 7-bit value in the range [-140, -44] dBm with 1dB step size, if the higher layer parameter nrofReportedRS is configured to be larger than one, or if the higher layer parameter groupBasedBeamReporting is configured as 'enabled', or if the higher layer parameter groupBasedBeamReporting-is configured, the UE shall use differential L1-RSRP based reporting, where the largest measured value of L1-RSRP is quantized to a 7-bit value in the range [-140, -44] dBm with 1dB step size, and the differential L1-RSRP is quantized to a 4-bit value. The differential L1-RSRP value is computed with 2 dB step size with a reference to the largest measured L1-RSRP value which is part of the same L1-RSRP reporting instance. The mapping between the reported L1-RSRP value and the measured quantity is described in [11, TS 38.133].

Summary #1 of discussion
Thanks to companies for the inputs. 
Based on the feedback received from Nokia by in the moderator summary and companies (NTT DOCOMO, Fujitsu, Google, vivo, Huawei) offline discussion in RAN1#120 meeting, we can see that majority of companies agree to change TS 38.214 to resolve inconsistency issue on aperiodic LTM CSI reporting configuration, specific spec changes are as follows:
Change “Each trigger state in CSI-AperiodicTriggerStateList contains a list of associated CSI-ReportConfigs or LTM-CSI-ReportConfigs” in clause 5.2.1 of TS 38.214 to “Each trigger state in CSI-AperiodicTriggerStateList contains a list of associated CSI-ReportConfigs or one associated LTM-CSI-ReportConfig”.

Moderator proposal for online session (Tuesday)
Given the above situation, Moderator recommends the following proposal:
Proposal 1: In order to align aperiodic LTM CSI reporting configuration in TS 38.214 and TS 38.331, the following update is adopted in clause 5.2.1 of TS 38.214.
Change “Each trigger state in CSI-AperiodicTriggerStateList contains a list of associated CSI-ReportConfigs or LTM-CSI-ReportConfigs” in clause 5.2.1 of TS 38.214 to “Each trigger state in CSI-AperiodicTriggerStateList contains a list of associated CSI-ReportConfigs or one associated LTM-CSI-ReportConfig”.

Title: 	Summary on discussion on aperiodic triggering offset of CSI-IM for Rel-18 Type-II Doppler codebook
Document for:	Discussion/Decision
Conclusion
Based on the feedback, companies’ views are summarized as following:
Essentially, all companies agree that aperiodic CSI-IM should be located at the earliest slot comprising aperiodic CMR, and different views are mainly about wording/English:
8 companies are OK to take the wording of CR2 (proposed in [3]);
1 company suggested refined wording;
1 company thinks that existing text in 214 has no ambiguity, thus CR is not needed.
Therefore, we have two possible ways to move forward:
Possible conclusion1: Take the following TP:

Possible conclusion2: RAN1 conclude that for Rel-18 Type-II Doppler and Type-II Doppler Port Selection codebook, aperiodic CSI-IM, if configured, follows the triggering offset of the associated NZP CSI-RS resource with the lowest resource ID for channel measurement.
CR is not needed.

Some online discussion would be beneficial.

Title:	Summary of AP CSI-RS active time for CSI report configured with ‘none’
Agenda Item:	7
Document for:	Discussion and Decision
Conclusion
According to Apple’s comments, CSI-RS resources associated with CSI reports for Beam management related are considered active resource in the slot in which the RS is transmitted, as shown in the following.
While according to current 38.214, e.g. for CSI report configured with ‘cri-RSRP’, if the associated CSI-RS resources are periodic, then they are considered to be active upon configuration and end at RRC release. Obviously, they are contrary with each other. Therefore, we believe a conclusion is needed for the proper reference in specs for active CSI-RS resources counting.
Proposal 1(updated_v2): make a conclusion that active resource counting for CSI-RS resources associated with CSI reports with reportQuantity set to 'ssb-Index-RSRP', 'cri-RSRP' or with reportQuantity set to 'none' and CSI-RS-ResourceSet with trs-Info is not configured is specified in TS38.306.

Proposal 
Proposal: Capture the following sentence in RAN1 chairman notes as conclusion to clarify the potential ambigurity: 
It is common undestanding that the ‘before reception of the activation command, …’ in the following paragraph of section 5.1.5 in TS 38.214 refers to ‘the activation command for any BWP’. 
If tci-PresentInDCI is set to "enabled" for the CORESET scheduling the PDSCH, and the time offset between the reception of the DL DCI and the corresponding PDSCH is equal to or greater than timeDurationForQCL if applicable, after a UE receives an initial higher layer configuration of TCI states and before reception of  the activation command, the UE may assume that the DM-RS ports of PDSCH of a serving cell are quasi co-located with the SS/PBCH block determined in the initial access procedure with respect to 'QCL-TypeA', and when applicable, also with respect to'QCL-TypeD'.
No CR is needed.

To RAN2
ACTION: 	RAN1 respectfully asks RAN2 to take the information into consideration.

From moderator’s assessment, although a few companies argue that we do not have to send an LS to RAN2 regarding the LS, the other few companies believe we should reply to the answers raised by RAN2. As the moderator, I tend to agree that we should send the reply to RAN2 as they have made changes on the spec and seek the advice from RAN1. We should reply to the questions 2A and 2B raised from RAN2. And of course, please provide your views on whether/how we capture the conclusion in the reply LS.
Q1: Do you agree to have a reply LS? If yes, do you agree with the draft reply LS?

Proposal for online discussion
Since I did not receive any negative comments on sending the reply LS to RAN2, I suggest that we provide such a LS.
Proposal 1: Provide the reply LS to RAN2 for the discussion regarding the differentiation of sDCI based mTRP and sTRP. Final LS is in R1-2504885.

6.2.2	UE DM-RS transmission procedure
*** Unchanged parts are omitted ***
When transmitted PUSCH is scheduled by DCI format 0_1 with CRC scrambled by C-RNTI, CS-RNTI, SP-CSI-RNTI or MCS-C-RNTI, or corresponding to a configured grant, or being a PUSCH for Type-2 random access procedure,
-	for a configured-grant based PUSCH transmission in RRC_INACTIVE state, the UE is provided with a set of DM-RS port(s) by sdt-DMRS-Ports. The DM-RS port for the PUSCH is determined by the mapping between SS/PBCH block(s) and a PUSCH occasion and the associated DM-RS resource as described in Clause 19.1 of [6, TS 38.213]. 

-	the UE may be configured with higher layer parameter dmrs-Type in DMRS-UplinkConfig, and the configured DM-RS configuration type is used for transmitting PUSCH in as defined in Clause 6.4.1.1 of [4, TS 38.211].

R1-2504823	Summary#2 on startSFN for positioning SRS FH	Moderator (ZTE)

Agreement
The draft LS content in section 4 of R1-2504823 is endorsed.

Answer to Q1: No, parameter start SFN is not needed for UTW for positioning SRS frequency hopping. The parameter periodicityAndOffset-r18 and periodicityAndOffset-Ext-r18 for UTW already covers the startSFN and they indicate the periodicity in slots and the offset of the starting slot with respect to SFN#0 slot#0.

Final LS in R1-2504854.
