Claim 0:
1. A method, comprising:
receiving, by a first wireless device, a first reference signal (RS) over an receive (RX) radio frequency (RF) chain of the first wireless device;
transmitting, by the first wireless device, a second RS over a transmit (TX) RF chain of the first wireless device using beams determined based on the first RS;
receiving, by the first wireless device from a second wireless device, a second quality parameter corresponding to the second RS;
comparing, by the first wireless device, 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, by the first wireless device, 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.
