Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration indicating a set of resources for a reference signal to track an in-phase and quadrature-phase imbalance of the UE. The set of resources may include a first subset of resources for transmitting the reference signal and a second subset of resources for a mirror image signal that is generated during upconversion of the reference signal. The UE may upconvert the reference signal to a set of subcarriers corresponding to the first subset of resources and transmit the upconverted reference signal on the first subset of resources. The base station may receive the reference signal and the mirror image signal and determine a signal adjustment for communications with the UE based on the received reference signal and the received mirror image signal.
