Sidelink 6G

Technical Explanation

Sidelink enables devices to communicate directly with each other over the PC5 interface. In 6G, Sidelink is upgraded with Sub-THz frequencies, full-duplex operation, and cooperative multi-hop relaying. Connected autonomous vehicles, delivery drones, and AR glasses stream raw video, radar point clouds, and trajectory intents to nearby devices with sub-0.5 millisecond latency, maintaining vital collision avoidance even when driving through underground tunnels without cellular coverage.

Key Functions

• Direct device-to-device transmission bypassing base station infrastructure entirely
• Sub-0.5 millisecond air interface latency for mission-critical vehicle collision avoidance
• Autonomous decentralized resource allocation functioning without cellular coverage
• High-throughput cooperative sensor sharing (collective perception) among vehicle swarms
• Sub-THz sidelink supporting high-speed local data swapping between nearby AR headsets
