Claim 0:
1. A method for wireless communication at a user equipment (UE), comprising:
receiving, via a downlink channel, a downlink message comprising an indication of a precoder applied to one or more downlink signals;
receiving the one or more downlink signals using at least one demodulation reference signal and the precoder, wherein the one or more downlink signals are at least partially mismatched in gain and phase;
performing an iterative channel estimation procedure to estimate the downlink channel;
performing a gain and phase mismatch equalization procedure at the UE to equalize an estimated gain and phase mismatch of the one or more downlink signals based at least in part on the estimated downlink channel and the precoder; and
receiving one or more equalized downlink signals in accordance with the gain and phase mismatch equalization procedure.
