Abstract: 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.
