Abstract
Methods, systems, and devices for wireless communications are described. A first wireless device may identify a translational or rotational misalignment between a first antenna array of the first wireless device and a second antenna array of a second wireless device that is in line-of-sight (LoS) wireless communication with the first wireless device via a channel. The first wireless device may update a channel matrix for the channel based on the translational or rotational misalignment, where the first wireless device may update the channel matrix with one or more beam steering metrics of the first antenna array so as to improve a beam alignment between the first antenna array and the second antenna array. The first wireless device may communicate with the second wireless device in accordance with the updated channel matrix.
