9.4.1Connected mode mobility
Agreed
6G supports both network- and UE-triggered mobility
The resource reservation study will continue for both mobility types, with UE-triggered mobility using pre-configuration.

Quote from the record
Both NW-triggered mobility and UE-triggered mobility with pre-configuration is supported in 6G. For both UE-triggered and NW-triggered mobility we continue the resource reservation study.

Agreed
Network control is the baseline for early downlink sync

Preconfigured measurement gaps are reused for prediction fallback
The reused gap is configured per measurement object for inter-frequency prediction.
Source:R2-2605831 (meeting or session report, paragraphs 255, 267 and 272). 3GPP TSG RAN WG2 #135.
Quote from the record
Preconfigured measurement gap (per MO) is reused for fallback operation for inter-frequency prediction.

Agreed
Predicted frequencies can be configured without co-located information
They can be listed in otherConfig as a partial inference configuration for inter-frequency prediction.

Xiaomi
Xiaomi's submitted proposal makes UE-based candidate-cell pre-configuration the power-saving baseline.Their words
For power-saving CONNECTED mobility study, UE based mobility with pre-configuration of candidate cells and with UE notification upon cell change (i.e., a CHO/C-LTM like mechanism) [...]

ETRI
ETRI proposes power-saving enhancements while maintaining network-controlled mobility.Their words
RAN2 studies enhancements to the existing power saving mechanisms in connected mode, such as DTX/DRX operation and measurement/reporting relaxation, while maintaining NW-controlled mobility.
R2-2605577Proposal 6, paragraph 108 · register: not treated
8.3.2Inference related LCM procedure
Proposed
What should the UE do when inference configuration cannot be used?
Submissions differ on UE behavior when inference configuration fails. One proposes stopping inference and reporting, while another proposes continuing when fallback is barred.

What they propose

UNISOC
UNISOC proposes following the current measurement gap and stopping inference and reporting when no preconfigured gap exists.Their words
If there is no preconfigured MG, UE follows the current MG, stops the inference and inference report procedures, and waits for reconfiguration.
China Telecom proposes continuing inference and reporting inapplicability when full configuration fails and fallback is disallowed.Their words
Proposal 1: If the full inference configuration becomes inapplicable and fall back is not allowed, UE continues inference operation and reports inapplicability status to the [...]
Fraunhofer IIS and Fraunhofer HHI say CA and DC mainly benefit peak rate, while multi-carrier deployment can add capacity without aggregation.Their words
Observation 1: Spectrum Aggregation (CA and DC) is mostly beneficial to peak data rate increase. [...]

Samsung (with Verizon)
Samsung and Verizon identify CA and DC as typical LTE and NR spectrum-aggregation schemes.Their words
Observation 1: Carrier Aggregation and Dual Connectivity are the typical schemes to utilize the spectrum aggregation in LTE and NR.
R2-2604693Observation 1, paragraph 12 · register: available
A pre-meeting submission reports field-test gains for both DL and UL in non-collocated FR1-FR2 aggregation.Their words
Observation 1: Field tests demonstrate substantial performance gains with both downlink and uplink spectrum aggregation for the non-collocated FR1-FR2 scenario.
R2-2605568Observation 1, paragraph 30 · register: not treated
Resource reservation for both network-triggered and UE-triggered mobility remains under study.

Scout read 28 recorded decisions and 137 company positions or contribution passages on these agenda items (catalog synced 2026-09-29) and cites 14 decisions and 7 positions from 10 TDocs. Every quoted passage was matched verbatim against the TDoc text; the summaries around the quotes are Scout's reading. Register statuses are copied from the 3GPP TDoc register: not treated means a document was not handled on its own, though its content may have fed feature-lead summaries or merged revisions. Not covered: other agenda items and meetings, plenary TDocs and plenary decisions after the meeting, email discussions after the meeting, and anything not yet in the chair notes or register.
Spectrum aggregation coverage is limited to an approved outgoing LS and company observations.
