Multi-Band CA
Multi-Octave Extreme Carrier Aggregation
Simultaneously aggregating carrier channels across widely disparate spectrum bands—from low Sub-1GHz to mid FR3 and high Sub-THz.
Technical Explanation
In 5G, carrier aggregation typically combined adjacent or nearby frequency bands. 6G Multi-Band CA aggregates channels across multiple octaves of spectrum simultaneously: a 20 MHz anchor carrier in Sub-1GHz for bulletproof control plane reliability, a 500 MHz carrier in FR3 (10 GHz) for broad coverage, and a 10 GHz ultra-wideband pipe in Sub-THz (150 GHz) for peak data dumping.
Key Functions
- Simultaneous aggregation of up to 32 carrier channels spanning 1 GHz to 300 GHz
- Decoupling uplink and downlink bands across optimal physical propagation frequencies
- Instantaneous packet-level switching between Sub-THz and Sub-6GHz upon line-of-sight blockage
- Delivering combined peak user throughput exceeding 100 Gbps across multi-tier spectrum
- Dynamic carrier activation based on user buffer queue depth to optimize battery drain
