vs RAN1#124
Ericsson appears as a new contributor to these topics at RAN1_124bis, with no corresponding position in the RAN1_124 consolidated positions. Their proposal spans four distinct areas: (1) reusing Rel-19 CLI enhancements as baseline and studying a unified CLI framework with both L3 and L1 configuration that is separate from the CSI framework; (2) adding 6GR-specific information in the RIM set ID with Framework-1 priority; (3) introducing CB-BSR as an alternative to single-bit SR, supported by DMRS-port and scrambling-sequence contention-resolution simulations; and (4) new UE measurements for downlink interference classification into intra-system, external unintentional, and deliberate jamming types. No prior stance exists for comparison.

Position extracted by AI
Ericsson proposes reusing Rel-19 BS-to-BS and UE-to-UE CLI enhancements as the 6GR baseline and supports studying feasibility of BS flexibly configuring both L3 (MeasObjectCLI) and L1 (CSI-ResourceConfig) UE-to-UE CLI measurement configuration and reporting, moving toward a potentially unified CLI framework separate from the CSI framework. They require embedding 6GR-specific information in the RIM set ID to enable differentiation of remote interference scenarios across 5G and 6G networks and prioritize RIM Framework-1 over FW-0 and backhaul-based FWs 2.1/2.2 to simplify design and interoperability. They propose studying contention-based multi-bit buffer-status reports (CB-BSR) as an alternative to single-bit scheduling requests, demonstrating via simulations that allocating different DMRS ports or scrambling sequences can avoid excessive BLER when multiple UEs select the same contention resource. They propose studying new UE measurements and related procedures for downlink interference classification to distinguish intra-system, external unintentional, and deliberate jamming interference types.
Summary
Ericsson presents 6 proposals and 5 observations across 6G physical layer topics: cross-link interference (CLI) reuse from Rel-19 with potential L1/L3 unification, remote interference management (RIM) prioritizing Framework-1 with 6G-specific set ID embedding, contention-based multi-bit scheduling requests (CB-BSR) with DMRS design study, and interference identification requiring new UE measurements for classification.
