Abstract
In some aspects, the disclosure is directed to methods and systems for in-packet transmission power control. Measurement circuitry in communication with a transmission stage of a device is configured to generate a transmitted signal strength measurement signal based on an output of the transmission power amplifier during transmission of a packet. Measurement conversion circuitry connected to the measurement circuitry is configured to convert the transmitted signal strength measurement signal from the measurement circuitry to an output power measurement. Power control circuitry connected to the measurement conversion circuitry is configured to generate a power correction signal based on the output power measurement and an output power target value. Power ramping circuitry connected to the power control circuitry is configured to provide a gain signal to the transmission stage of the device based on the power correction signal.
