METHOD OF CONTROLLING POWER SUPPLY FOR AMPLIFYING RADIO FREQUENCY SIGNAL AND COMMUNICATION APPARATUS FOR PERFORMING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18086642 titled 'METHOD OF CONTROLLING POWER SUPPLY FOR AMPLIFYING RADIO FREQUENCY SIGNAL AND COMMUNICATION APPARATUS FOR PERFORMING THE SAME
Simplified Explanation
The patent application describes a method for controlling the power supply in amplifying a radio frequency (RF) signal. The method involves determining the power supply mode, such as envelope tracking (ET) mode, which supplies power based on the ET of the RF signal.
- The method checks if the downlink block error rate and downlink modulation method in the ET mode meet a first condition.
- If the first condition is satisfied, the method determines if a full resource block (RB) in the uplink band is allocated for uplink data transmission.
- If the full RB is allocated for uplink data transmission, the power supply mode is switched to average power tracking (APT) mode, which supplies power based on the average power of the RF signal.
Potential applications of this technology:
- Wireless communication systems
- Mobile devices and smartphones
- Radio transmitters and amplifiers
Problems solved by this technology:
- Efficient power supply control for amplifying RF signals
- Optimization of power supply modes based on signal conditions
- Reduction of power consumption and improved overall performance
Benefits of this technology:
- Enhanced power efficiency in RF signal amplification
- Improved signal quality and reliability
- Extended battery life in mobile devices
Original Abstract Submitted
A method of controlling power supply for amplifying a radio frequency (RF) signal includes: determining whether a power supply mode for supplying power from a power modulator of a communication apparatus to an amplifier for amplifying the RF signal is an envelope tracking (ET) mode for supplying power based on ET of the RF signal; when the power supply mode is the ET mode, determining whether a downlink block error rate in the ET mode and a downlink modulation method in the ET mode satisfy a first condition; when the first condition is satisfied, determining whether a full resource block (RB) in an uplink band is allocated to uplink data transmission; and when the full RB in the uplink band is allocated to uplink data transmission, switching the power supply mode to an average power tracking (APT) mode for supplying power based on average power of the RF signal.
