Asymmetric Carrier Aggregation

Technical Explanation

Mobile smartphones have severe battery constraints and small internal power amplifiers, making high-power Sub-THz transmissions challenging. Asymmetric Carrier Aggregation pairs asymmetric physical bands: the base station (which has access to wall power and massive antenna panels) transmits downstream to the phone over a massive 10 GHz Sub-THz channel, while the phone transmits its uplink acknowledgments and data back to the tower on a penetrating, battery-friendly 700 MHz band.

Key Functions

• Pairing massive high-frequency downlink spectrum with low-frequency penetrating uplink spectrum
• Overcoming mobile smartphone battery and power amplifier transmission limits in Sub-THz
• Delivering multi-gigabit download speeds while maintaining broad uplink coverage reach
• Eliminating the need for bulky, battery-draining power amplifiers inside handheld smartphones
• Decoupling uplink and downlink cell associations for optimal radio resource efficiency
