5G NR V2X: Ultra-Reliable Low-Latency Sidelink for Autonomous Fleets

NRV2X delivers reference architectures for 3GPP Release 16 and 17 NR Sidelink, empowering automated driving functions with sub-millisecond roundtrips and high-throughput data exchange.

Beyond Basic Safety: Enabling High-Bandwidth Cooperative Maneuvers

Where legacy V2X broadcasts basic telemetry, 5G NR V2X introduces flexible numerology, physical sidelink feedback channels, and connection-oriented communication for platooning and sensor sharing.

Core Engineering Areas

• Flexible Numerology & Subcarrier Spacing — Adapting 15, 30, 60, and 120 kHz subcarrier spacing to optimize latency and Doppler robustness.
• Sidelink Unicast & Groupcast — Connection management, pairing handshakes, and geographic distance-based acknowledgments.
• High-Throughput Sensor Sharing — Streaming LiDAR feature vectors, stereo camera feeds, and occupancy grids between automated vehicles.
