Classification: CPC G  H | IPC H

Claim 13:
14. An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:
a memory;
a transceiver; and
at least one processor coupled to the memory and the transceiver and configured to:
select 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;
determine an orthogonal matrix based on the sub-matrix of the DFT matrix;
determine a codebook based on the orthogonal matrix, the codebook including a plurality of codepoints; and
transmit, via the transceiver, 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.
