Abstract:
Various aspects described herein relate to adjusting transmit power of a radio frequency (RF) transceiver. A total power adjustment for adjusting a transmit power of the RF transceiver can be determined. The transmit power can be adjusted to a first adjusted transmit power based at least in part on a first adjustment size that is less than the total power adjustment and determined based at least in part on the transmit power. Digital pre-distortion (DPD) training of the RF transceiver can be performed to adjust one or more coefficients for calibrating the RF transceiver based on the first adjusted transmit power. The first adjusted transmit power can be adjusted to a second adjusted transmit power based at least in part on a second adjustment size that is less than the total power adjustment and computed based at least in part on the first adjusted transmit power.
