Sidelink Carrier Aggregation
Multi-Carrier Aggregation Across Sidelink PC5 Channels
Combines multiple sidelink frequency channels simultaneously, achieving multi-gigabit direct vehicle-to-vehicle sensor and video sharing.
Technical Explanation
Connected autonomous vehicles must share raw high-definition LiDAR point clouds and 4K camera feeds with nearby vehicles to see through obstacles. Rel-18 Sidelink Carrier Aggregation bonds multiple sidelink component carriers (in both licensed and unlicensed spectrum), delivering multi-gigabit direct data throughput between moving vehicles.
Key Functions
- Aggregates multiple direct sidelink component carriers into a single logical pipe
- Achieves multi-gigabit transmission speeds directly between moving autonomous vehicles
- Transports high-density raw LiDAR point clouds and 360-degree video sensor feeds
- Enhances collective environmental perception across cooperative vehicle fleets
