Abstract
Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to transmit one or more reference signals to a second wireless device using a first antenna array at the first wireless device and in accordance with a first precoder matrix. The first wireless device may receive, from the second wireless device based on the one or more reference signals, a feedback message indicating an estimated rotational misalignment, an estimated spatial misalignment, or both, between the first antenna array at the first wireless device and a second antenna array at the second wireless device. The first wireless device may then transmit a message to the second wireless device in accordance with a second precoder matrix that is modified relative to the first precoder matrix based at least in part on the estimated rotational misalignment, the estimated spatial misalignment, or both.
