10.5.2.4 shiftedShifted baseline stance: prior meeting proposed reusing Rel-18/19 inter-cell AI/ML BM framework for D-MIMO; current meeting adopts Rel-17/18 unified TCI framework and QCL rules as baseline without redesign, broadening the foundation. Added new proposal to study streamlined QCL chain design evaluating removal or reduction of UE-specific periodic TRS as QCL source RS, explicitly assessing impacts on tracking robustness, system performance, and overhead—no such QCL-chain critique appeared before. Dropped earlier emphasis on Set A/Set B mechanism reuse for TRP selection and the specific L1-RSRP N=6 or 8 limitation argument for joint transmission scheduling. Added new event-driven UEIBM UL reporting framework proposal eliminating Events 1, 2, 3, 9 as redundant, modifying Event-5 to support mTRP dynamic switching between DPS and CJT modes, and specifying aperiodic UL procedure with conditional network response—substantially more detailed than prior meeting's general temporal beam prediction extension to D-MIMO. Added study of associated ID limitations including potential disclosure of NW proprietary information, not previously discussed.
New positions this meeting
- 10.5.2.3 — Proposes a PUCCH-less uplink control architecture combining Option 2 (UCI on PUSCH) and Option 3 (other methods), with UCI conveyed via MAC CE on PUSCH when resources are available. For cases without scheduled resources, proposes CB-PUSCH-SR for synchronized UEs and minimized 2-step PRACH-SR for unsynchronized or coverage-limited UEs, with non-overlapping operation based on uplink synchronization status and implicit SR acknowledgement via MsgB or uplink grant.
- 10.5.4.1 — Proposes a single-stage DCI baseline for 6G and explicitly argues that two-stage DCI introduces multi-step dependencies, timing constraints, and additional failure modes. Proposes a fixed-size unified DCI format (40-bit example) separating baseline DCI fields on PDCCH from feature-dependent information moved to PDSCH-embedded signaling and RRC-configured profiles. Proposes hash-conditioned early termination using a Target Identification Field (TIF) mapped to early polar bit positions. Proposes restricting SearchSpaceSets, aggregation levels, and candidate counts as configuration levers for blind decoding complexity, and handling cross-carrier scheduling via SearchSpace-bound carrier context or compact Carrier-Group ID.

Considerations for the downlink control channel, scheduling for downlink and uplink transmissions
Kyocera presents 5 Observations and 4 Proposals arguing for a single-stage DCI design with a fixed-size unified format for 6G, moving feature-dependent fields from PDCCH to PDSCH or RRC to limit blind decoding hypotheses and candidates,…
PUCCH-less 6GR
Kyocera proposes a PUCCH-less uplink control architecture as a baseline for 6GR, where UCI (HARQ, CSI, SR) is conveyed via MAC CE on PUSCH when resources are available, and a minimized SR-replacement mechanism is used otherwise. Three…
Beam management for downlink and uplink

Beam Management for Multi-TRP transmission in 6GR
Kyocera presents 5 proposals for AI-based beam management for multi-TRP transmission in 6G, arguing that Rel-18/19 AI/ML frameworks should be reused and extended to Distributed MIMO scenarios with more than 2 TRPs, while studying beam…
