Ue feedback for layer reduction

An apparatus of wireless communication at a network entity, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to:
• receive, from a user equipment (UE), channel information comprising at least one of:
• a set of mutual information for each layer of a first number of layers associated with a channel between the UE and the network entity, or
• rank reduction information for a rank reduction of the channel;
• identify, based on the channel information, a precoding scheme for communication between the UE and the network entity;
• and
• communicate, based on the channel information and the precoding scheme, with the UE.

A method of wireless communication at a user equipment (UE), comprising:

• obtaining channel information comprising at least one of:
• a set of mutual information for each layer of a first number of layers associated with a channel between the UE and a network entity, or
• rank reduction information for a rank reduction of the channel;
• transmitting, to the network entity, the channel information for an identification of a precoding scheme for communication between the UE and the network entity;
• and
• communicating, based on the channel information and the precoding scheme, with the network entity.
