R1-2501562         FL Summary #3 on Rel-19 TEIs   Moderator (NTT DOCOMO, INC.)

From Thursday session

R1-2501539         Draft LS on non-RedCap UE UL SRS frequency hopping for positioning          ZTE Corporation, Sanechips

Decision: The draft LS to RAN2 is endorsed with following information:

In RAN1#120 meeting TEI agenda, RAN1 has made the following agreement for enabling non-RedCap UE performing UL SRS frequency hopping for positioning:

Agreement

Ÿ   Extend Rel-18’s UL frequency hopping UL SRS for positioning transmission to non-RedCap UEs in a single carrier

Ÿ   UE capability for non-RedCap UEs for UL SRS frequency hopping for positioning transmission

Send LS to RAN2 to inform this agreement, whether new parameter is needed is up to RAN2 discussion.

As this agreement may relate to RAN2 specification, this liaison informs RAN2 about this agreement and whether new parameter for non-RedCap UE UL frequency hopping is needed is up to RAN2 discussion.

To RAN2

ACTION: RAN1 respectfully asks RAN2 to take the agreement into account in their Rel-19 specification, and feedback if there is any spec impact.

Final LS is approved in R1-2501573.

 

Agreement

To resolve ambiguities with concurrent configuration of SRS-CS and ulTxswitch in a case where a UE configured with SRS CS on target CC and its “switch-from” CC on CC2 and configured with UL Tx switching operation for UL CC2 and at least one UL CC1 

·       Confirm that the prioritization rules in 38.214 Sec. 6.2.1.3 are applied between target and CC1, regardless of SRS-AS antenna port configuration on target CC, if UE indicates based on srs-SwitchingAffectedBandsListNR-r17 that SRS-CS on target impacts CC1, where CC1 is one of the CC(s) which may share Tx chains with source CC. No spec change is needed.

o   Note: if UE does not indicate srs-SwitchingAffectedBandsListNR-r17, UE can only perform simultaneous transmission when the total number of involved Tx chains for simultaneous transmission on all the bands/carriers is not greater than number of Tx chains supported by the UE for simultaneous UL transmission. No spec change is needed. 

·       If the UE is under the operation state in which all Tx chains are available at the source CC, the required switching time before the beginning of SRS-CS transmission on target CC is SRS-SwitchingTimeNR. Otherwise, the required switching time before the beginning of SRS-CS transmission on target CC is indicated by a UE capability. Details about UE capability will be discussed in UE feature session.

·       The existing scheduling restriction of maximum one switching per reference slot for UL Tx switching is also taking into account the triggered SRS CS.

·       After SRS transmissions within an SRS resource set is done, if UE is indicated to transmit on CC1, the required switching time between the end of SRS-CS transmission on target CC and start of UL transmission on CC1 is indicated by the UE capability defined above. Otherwise, it is assumed for the determination of any future switching time that all Tx chains are returned to the source CC, and the RF tuning time to switch from target to source will be SRS-SwitchingTimeNR.

From Wednesday session

Agreement

For simultaneous CSI-RS reception in UE features 2-33, 2-36, 2-40, 2-41, 2-43, 16-3a and 16-3b, define 1 new UE capability:

·        UE capability 1: To allow the UE to indicate that CSI-RS ports within one periodic/semi-persistent CSI-RS resource, as well as the periodic/semi-persistent CSI-RS resource, are counted as one resource, even if the periodic/semi-persistent CSI-RS resource is referred by N Report Settings.

Agreement

The non-MBSFN subframes containing the cell acquisition signals (PSS/SSS/PBCH/SIB1) in an MBMS-dedicated cell shall only be transmitted within the first (k×40) ms out of every (n×160) ms.

·        Introduce a new parameter n, to be configured for support MBMS, from the set {2,4,8,16}.

·        Introduce a new parameter k, to be configured for support MBMS, from the set {4,5,6,7,…,63}.

·        In the absence of the above parameters {n,k}, all non-MBSFN subframes containing cell acquisition signals in an MBMS-dedicated cell shall be transmitted.

NOTE: For a MBMS-dedicated cell, there is no RAN4 impact from the above TEI proposal.

 

Agreement

Adopt the following TP to Section 6.2.1.4.1, TS 38.214.

6.2.1.4.1  SRS frequency hopping for positioning

<Unchanged parts are omitted>

For operation in the same carrier, the reduced capability UE is not expected to be activated or triggered to transmit SRS on overlapping symbols with a SRS resource of the transmit frequency hopping configured by the higher layer parameter SRS-PosTx-Hopping including the switching time to or from the active bandwidth part and a SRS resource with resourceType of both SRS resources as 'semi-persistent' or 'aperiodic'.

A UE shall perform SRS frequency hopping for positioning according to clause 6.2.1.4.1, subject to UE capability, with the following modifications:

‐           “reduced capability UE” is replaced by “UE”

‐           The reduced capability UE transmit frequency hopping is configured within one SRS resource for positioning in higher layer parameter srs-PosConfig, that may be configured with a bandwidth larger than the maximum bandwidth of the reduced capability UE” is replaced by “The UE transmit frequency hopping is configured within one SRS resource for positioning in higher layer parameter srs-PosConfig”.
