vs RAN1#124
Ericsson enters the discussion as a new contributor with a comprehensive set of proposals. They position enhanced CA as the primary spectrum aggregation mechanism, defining Gothia cell only conditionally as a fallback. On duplexing, they propose removing SFI-based (DCI 2_0) operation for dynamic TDD and introduce two new frame resource types (Mixed DL/UL and None), while requiring deprioritization of gNB dynamic SBFD, gNB FD, and UE SBFD. New specific coverage requirement values appear (1 Mbps DL / 30 kbps UL at MaxCL 143 dB). Additional new proposals include MRSS/IoT coexistence via aligned 5G/6G RB boundaries and dynamic CORESET sharing, time-asynchronous UCI reporting with L2-based MAC CE transmission, and multi-bit contention-based scheduling requests.

6G general aspects and frameworks
Position extracted by AI
Ericsson proposes enhanced carrier aggregation (CA) as the primary 6G spectrum aggregation tool, requiring means for fast/instant activation, same-configuration indications, multi-carrier single-DCI scheduling, and removing tight time-synchronous dependencies like DAI. They require deprioritizing gNB dynamic SBFD, gNB FD, and UE SBFD in the duplexing study, proposing removal of SFI-based (DCI 2_0) operation for dynamic TDD and introducing new 'Mixed DL/UL' and 'None' frame resource types. They propose aligning 5G/6G RB boundaries and enabling dynamic CORESET sharing for MRSS, while defining a virtual carrier ('Gothia cell') only if it solves problems not addressable by CA enhancements. They propose specific coverage requirement values (e.g., 1 Mbps DL / 30 kbps UL at MaxCL 143 dB) and strive for time-asynchronous UCI reporting with L2-based MAC CE transmission and multi-bit contention-based scheduling requests.
Summary
Ericsson's Tdoc R1-2601876 provides 31 proposals and 8 observations across 8 main sections, covering spectrum aggregation, MRSS/IoT coexistence, channel bandwidth, duplexing, coverage, and UCI transmission for 6G. The document emphasizes lessons learned from 5G NR to reduce complexity.

How this was derived
The AI extracted the "position extracted" field above directly from each Tdoc during summarization.
For the delta summary at the top, the AI compared Ericsson's consolidated stance at RAN1#124bis
against their stance at RAN1#124 and classified the change as
new.
