16 November to 20 November 2026Calgary3GPP TSG RAN WG4Last updated 2026-11-10
At a glance
The meeting examines 6G UE grouping for RRM, channel models, output power and radiated performance.
UE grouping proposals differ on whether maintaining a group needs separate criteria.
Output power proposals disagree on whether to specify ΔTRxSRS, remove it, or define a separate requirement.
Channel model work also addresses 400 MHz test equipment constraints and cross-polarization modelling.

MediaTek proposes standardized, verifiable criteria for maintaining a 6G UE group. China Mobile opposes separate maintenance criteria and proposes using establishment criteria and group updates instead.
The proposed maintenance checks reuse RSRP and RSRQ differences between UEs, with separate thresholds for hysteresis and time-to-trigger. The disagreement concerns how group membership is maintained after establishment, not whether grouping is studied.
8.7.2
Channel model
Significance 49 of 100, 14 TDocs
Qualcomm proposes identifying test equipment and fader bandwidth constraints for practical rCDL implementation at 400 MHz. Nokia proposes against using XP models without further cross-polarization modelling updates.
The bandwidth question concerns whether the channel model can be implemented in the intended test setup. The XP proposal concerns the model itself, so the two submissions address different parts of test design.
Qualcomm
Proposal
RAN4 to identify in this Study Item potential test equipment/fader bandwidth constraints relevant to the practical rCDL implementation at 400 MHz.
Output power submissions offer different treatments of ΔTRxSRS. LG Electronics proposes using tolerable SRS power imbalance to guide a requirement, while Huawei (with HiSilicon) opposes defining one.
OPPO proposes removing ΔTRxSRS from the equation without specifying a requirement. ZTE (with Sanechips) also prefers removal from the equation, but proposes a separate requirement.
UE RF work includes proposed values and device classifications for specific satellite-related cases. Sharp proposes a 2 dB ΔRIBC value for VSAT types 2 and 5.
LG Electronics proposes VSAT type 8 for a small, electronically steered Ka-band device using HD-FDD with LEO. These proposals address different requirements, so neither resolves the other.
Radiated performance work examines how TAS state affects measurement. Samsung proposes recording the advantages and disadvantages of TAS OFF and TAS ON measurement in the 6G TR.
Apple proposes studying TAS-ON dwell time so antenna selection can settle before capture. Its proposal would have manufacturers declare dwell time within a range that remains FFS.
Samsung
Proposal
Capture the following pros and cons analysis into 6G TR for TAS OFF and TAS ON measurement:
