Xhaul6G：6G統合NTNトランスポート＆Sub-THzワイヤレスフロントホール

Xhaul6Gは、地上基地局、高高度プラットフォーム（HAPS）、LEO衛星をSub-THz電波および光メッシュでシームレスに結合する統一6Gトランスポート仕様を策定します。

Xhaul6G Terrestrial-Space Unified Transport Mesh

Cross-layer routing across sub-THz wireless fronthaul and 1 Tbps coherent space optical trunks

Central System: 6G Terrestrial Extreme-MIMO Cell - 140 GHz sub-THz active antenna unit (AAU)

Network Nodes

  • 6G Terrestrial Extreme-MIMO Cell
  • Stratospheric HAPS Relay (20 km)
  • Low Earth Orbit Laser Node (600 km)
  • 6G Cloud-Native Disaggregated Core

Architectural Protocol Layers

  • Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
  • Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
  • Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
