Sub-terahertz sub-band flattening feedback

An apparatus for wireless communication of a device, comprising:

• a memory;
• and
• at least one processor coupled to the memory, the at least one processor configured to:
• receive a reference signal;
• measure amplitude and phase of the reference signal relative to a set point;
• and
• transmit channel flattening information in a precoding feedback.

A method of wireless communication at a device, comprising:

• receiving a reference signal;
• measuring amplitude and phase of the reference signal relative to a set point;
• and
• transmitting channel flattening information in a precoding feedback.

An apparatus for wireless communication of a network device, comprising:

• a memory;
• and
• at least one processor coupled to the memory, the at least one processor configured to:
• transmit a reference signal;
• receive channel flattening information in a precoding feedback;
• apply the precoding feedback to a signal to transmit one or more data;
• and
• output the one or more data.

A method for wireless communication at a network device, comprising:

• transmitting a reference signal;
• receiving channel flattening information in a precoding feedback;
• applying the precoding feedback to a signal for transmitting one or more data;
• and
• outputting the one or more data.
