1. A method for wireless communications at a first wireless device, comprising:
identifying 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 wireless communication with the first wireless device via a channel;
updating a channel matrix for the channel based at least in part on the translational or rotational misalignment, the channel matrix updated 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;
communicating with the second wireless device in accordance with the updated channel matrix; and
transmitting, to the second wireless device, an indication of the translational or rotational misalignment between the first antenna array and the second antenna array.
