Channel precoder selection for uplink wireless communications

A method for wireless communications at a user equipment (UE), comprising:

• receiving, from a network entity, a set of neural-network based precoding coefficients for a neural-network based precoding function for generation of an uplink channel precoding matrix for at least a first uplink communication to be transmitted from the UE;
• obtaining a channel estimation associated with a wireless channel that carries the first uplink communication;
• generating the uplink channel precoding matrix based at least in part on application of the set of neural-network based precoding coefficients to the neural-network based precoding function and the channel estimation;
• and
• transmitting the first uplink communication via the wireless channel using the uplink channel precoding matrix that is based at least in part on application of the set of neural-network based precoding coefficients to the neural-network based precoding function and the channel estimation.
