Synthesized summary
The RAN1_123 meeting was dominated by contributions to the FS_6G_Radio work item, with a strong focus on foundational physical layer design topics. Recurring technical themes included the evaluation and selection of modulation schemes—particularly comparisons between 5G NR uniform QAM and alternatives like PSCM and ATSC 3.0 NUC—alongside discussions on waveform, numerology, and subcarrier spacing, with some proposals advocating for simplified configurations such as a 15 kHz-only SCS for FDD. Companies also addressed the scoping of AI/ML study use cases, often prioritizing one-sided models and proposing down-selection to a limited set of use cases, while early security alignment and system parameter evaluations were raised through inter-WG liaison statements.
