21. A method for wireless communications, at a network entity, comprising:
transmitting, via a first time slot, a first demodulation reference signal that is precoded according to a first set of precoding parameters for a user equipment (UE);
transmitting, via the first time slot, a second demodulation reference signal that is precoded according to a second set of precoding parameters for the UE;
receiving a feedback message indicating channel estimation information for the UE based at least in part on the first demodulation reference signal and the second demodulation reference signal;
performing, based at least in part on the feedback message and one or more other feedback messages for the UE, a channel prediction procedure for a second time slot subsequent to the first time slot; and
transmitting, via the second time slot, one or more messages that are precoded according to a third set of precoding parameters, the third set of precoding parameters predicted based at least in part on the channel estimation information and the channel prediction procedure.
