1. A method of wireless communication at a user equipment (UE), comprising:
selecting one or more even-numbered rows of a plurality of rows or one or more even-numbered columns of a plurality of columns in a discrete Fourier transform (DFT) matrix for a sub-matrix of the DFT matrix;
determining an orthogonal matrix based on the sub-matrix of the DFT matrix;
determining a codebook based on the orthogonal matrix, the codebook including a plurality of codepoints; and
transmitting at least one signal including a first codepoint of the plurality of codepoints in the codebook to convey a K bit payload in an uplink resource, where K is a positive integer.
