Claim 15:
16. A non-transitory computer-readable medium having instructions stored thereon that, when executed by a first wireless device, cause the first wireless device to perform operations, the operations comprising:
receiving a first reference signal (RS) over an receive (RX) radio frequency (RF) chain of the first wireless device;
transmitting a second RS over a transmit (TX) RF chain of the first wireless device using beams determined based on the first RS;
receiving, from a second wireless device, a second quality parameter corresponding to the second RS;
comparing between the second quality parameter corresponding to the second RS and a first quality parameter corresponding to the first RS to determine a difference between the second quality parameter and the first quality parameter; and
calibrating analog beamforming components of at least one of the TX RF chain or the RX RF chain based on the comparing between the second quality parameter and the first quality parameter.
