1. A method for wireless communication by a first wireless communication device, comprising:
transmitting, from at least a first antenna of a first antenna array of the first wireless communication device to at least a second antenna of a second antenna array of a second wireless communication device, a first set of reference signals that includes one or more reference signals, the first antenna array including a first set of antennas that includes a plurality of antennas including the first antenna;
transmitting, from two or more antennas of the first set of antennas of the first antenna array to two or more antennas of a second set of antennas of the second antenna array, a second set of reference signals that includes a plurality of reference signals, each respective reference signal of the plurality of reference signals being associated with a respective antenna of the first set of antennas and a respective antenna of the second set of antennas;
receiving, from the second wireless communication device in association with transmitting the first set of reference signals, an indication of a linear offset between the first antenna array and the second antenna array associated with phase measurements of the first set of reference signals;
receiving, from the second wireless communication device in association with transmitting the second set of reference signals, an indication of one or more rotational offsets between the first antenna array and the second antenna array associated with a plurality of phase measurements of the plurality of reference signals of the second set of reference signals; and
communicating with the second wireless communication device using the first antenna array in accordance with the indication of the linear offset and the indication of the one or more rotational offsets.
