Rel21Ready: 3GPP Release 21 演进路线、6G 亚太赫兹与地月中继深空通信标准

Rel21Ready 领航定义 3GPP Release 21 演进与 6G 正式商用标准前沿，深度融通 Sub-THz 太赫兹超宽带物理层、月球基地与火星地表深空网络，以及原生 AI 自适应空口架构。

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)
