1. A method for wireless communication at a user equipment (UE), comprising:
receiving a control message indicating at least two precoding matrices and a set of weighting coefficients for deriving a precoder for uplink transmission from the at least two precoding matrices;
deriving the precoder for transmission of an uplink message based at least in part on interpolating or extrapolating the at least two precoding matrices using the set of weighting coefficients; and
transmitting the uplink message, wherein the uplink message is precoded using the precoder.
