ELECTRONIC DEVICE AND METHOD FOR CONTROLLING TRANSMIT POWER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17946503 titled 'ELECTRONIC DEVICE AND METHOD FOR CONTROLLING TRANSMIT POWER
Simplified Explanation
An electronic device is described in this patent application that includes an antenna, a power amplifier, and at least one processor. The device is configured to transmit user data within a specific time slot during uplink transmission. The device is also able to adjust the supply voltage to the power amplifier based on the specific subcarrier spacing (SCS) used for transmitting the user data.
- The device identifies the user data to be transmitted within the first slot.
- It switches the supply voltage for the power amplifier to a voltage value corresponding to the desired transmission power.
- If the user data is transmitted using a second SCS that is greater than the first SCS, the device switches the supply voltage to the desired voltage value within a second duration in a second slot, which occurs before the initiation of the first slot.
- The device then transmits the user data with the desired transmission power using the power amplifier within the first slot to the base station.
Potential Applications
- This technology can be applied in various wireless communication devices such as smartphones, tablets, and IoT devices.
- It can be used in cellular networks to improve the efficiency and reliability of uplink transmission.
Problems Solved
- The technology solves the problem of efficiently transmitting user data within specific time slots during uplink transmission.
- It addresses the issue of adjusting the supply voltage for the power amplifier based on the subcarrier spacing used for transmitting the user data.
Benefits
- By adjusting the supply voltage based on the specific subcarrier spacing, the device can optimize the power amplifier's dynamic range, resulting in improved transmission performance.
- The technology allows for efficient and reliable uplink transmission, enhancing the overall communication experience for users.
Original Abstract Submitted
An electronic device include an antenna, a power amplifier and at least one processor configured to identify, transmit power of user data to be transmitted within a first slot in which uplink transmission is initiated; switch, based on identifying that the user data is transmitted based on a first SCS, supply voltage for dynamic range of the PA to a voltage value corresponding to the Tx power; switch, based on identifying that the user data is transmitted based on a second SCS greater than the first SCS, the supply voltage to the voltage value, within second duration in the second slot, the second duration in the second slot being before an initiation of the first slot; and transmit, using the PA, the user data with the Tx power within the first slot, to the base station.
