- 10.3.1 — Proposes studying concatenated BCH outer code with extended LDPC to mitigate error floor in high-reliability scenarios. Observes error floor impact becomes more pronounced as LDPC code block sizes increase to 16896 bits in high-throughput or sensitive NTN links. Proposes RAN1 evaluate BCH+LDPC using short BCH outer code (t≈8-10) focusing on post-decoding BER/BLER in error-floor region, HARQ retransmission impact, and latency for NTN, with implementation complexity assessment, drawing justification from DVB-S2/S2X standards (ETSI EN 302 307) for QEF performance.
- 10.7.1 — Requires NTN considerations from the outset of 6G radio design to avoid retrofitting non-optimizations. Proposes studying concatenated BCH outer code with LDPC inner code (BCH t ≈ 8-10, LDPC block size 16896 bits / 44 columns) for QEF performance and HARQ elimination in long-RTT NTN links. Identifies TR 38.811 K-factor parameterization as physically inconsistent and proposes revisiting. Requires support for all orbit types VLEO (300 km) through GSO (35,786 km) with earth-fixed steerable beams limited to 250 km footprint, all payload types including regenerative with functional BS split, and all duplex modes with GNSS-independent positioning.
Recent contributions
Considerations on 6G Radio for NTN
Thales presents 12 proposals and 5 observations in this 6G NTN contribution, urging that NTN-specific requirements be integrated from the outset of 6G radio design rather than retrofitted as in 5G. The document covers harmonized TN/NTN…
Considerations on 6GR Channel Coding
This Thales-led contribution proposes studying a concatenated BCH outer code with extended LDPC for 6G to mitigate the error floor in high-reliability scenarios. The document contains 2 Observations in the Introduction, 3 Observations in…
Discussion on waveform for 6GR air interface
Thales presents a comparative waveform analysis for 6G NTN, evaluating CP-OFDM, DFT-s-OFDM, WOLA, UFMC, BF-OFDM, F-OFDM, and OTFS against satellite link impairments including HPA non-linearities, Doppler, and delay. The document contains…
Overview of 6GR air interface
Thales and co-signatories present 7 proposals and 1 observation advocating for native NTN integration in the 6G radio design from the outset, emphasizing that 5G's late NTN addition led to non-optimized adaptations. The document details…
