Rel21Ready：3GPP Release 21技術ロードマップ＆6G Sub-THz・月面深宇宙NTN統合

Rel21Readyは、3GPP Release 21および6G商用標準の技術的最前線を定義し、Sub-THz無線、月面・火星通信インフラ、自律型AIネイティブ空口を統合します。

Rel21Ready 6G AI-Native Lunar & Terrestrial Unified Air Interface

Joint Communication and Sensing (JCAS) spanning Earth orbit to Lunar Artemis bases

Central System: Artemis Base 6G gNodeB - Cryo-hardened sub-THz cell tower at Lunar South Pole

Network Nodes

Artemis Base 6G gNodeB
Lagrange Point L2 Optical Gateway
Neural Autoencoder Air Interface
Unified 6G Planetary Core Network

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)
