NRSidelink: 3GPP 5G NR 사이드링크(PC5) 및 위성 협력 릴레이 시스템

NRSidelink는 PC5 인터페이스 기반 3GPP Rel-17/18 NR 사이드링크를 표준화하여 기지국 없이 단말 간 직접 탐색, 공공안전 통신 및 위성 협력 중계를 지원합니다.

NRSidelink PC5 Direct Communications & NTN Satellite Anchor

Mode 2 autonomous distributed resource allocation with satellite synchronization

Central System: Emergency Responder Terminal A - Standard 5G smartphone transmitting on PC5 sidelink

Network Nodes

  • Emergency Responder Terminal A
  • Emergency Responder Terminal B
  • Vehicle-to-Everything (V2X) Gateway
  • LEO Direct-to-Device Satellite

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)
