1. An apparatus for wireless communication at a station (STA), comprising:
one or more processors; and
one or more memories coupled with the one or more processors, the one or more memories storing instructions executable by the one or more processors to cause the apparatus to:
generate a channel state information matrix for each subcarrier of a plurality of subcarriers of a channel;
scale each value in the channel state information matrix using a scaling factor associated with a determined value in the channel state information matrix, wherein scaling each value in the channel state information matrix comprises scaling a real part of each value of the channel state information matrix using the scaling factor and scaling an imaginary part of each value of the channel state information matrix using the scaling factor; and
transmit, to a second device, a channel state information report that includes the scaled values of the channel state information matrix.
