Various aspects described herein relate to calibrating transceiver impairment in wireless communications. Direct current (DC) components of one or more signals can be modified, using one or more configured DC components, for transmitting to a user equipment (UE) via a transmitter. A receiver can receive the one or more signals as transmitted via the transmitter. An impairment of at least one of the transmitter, the receiver, or a combination thereof, can be determined based at least in part on comparing the DC components of the one or more signals as received via the receiver to the one or more configured DC components. One or more components of at least one of the transmitter, the receiver, or a combination thereof can be adjusted to compensate for the impairment.

Techniques for RF transceiver self-calibration

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.
