1. An apparatus for wireless communications at a user equipment (UE), comprising:
one or more processors;
memory coupled with the one or more processors; and
instructions stored in the memory and executable by the one or more processors to cause the apparatus to:
receive, from a network entity, a transmission comprising a data block modulated according to a modulation and coding scheme scheduled by the network entity; and
transmit, based at least in part on a result of a decoding process of the received transmission, a feedback message comprising a codepoint selected from a codebook comprising a set of codepoints corresponding to respective types of feedback and respective delta values, wherein the set of codepoints comprises a first subset of codepoints indicating that the decoding process was successful and a second subset of codepoints indicating that the decoding process was unsuccessful, and wherein a first codepoint of the first subset of codepoints indicates an increase to the modulation and coding scheme of a first delta value and a second codepoint of the second subset of codepoints indicates a decrease to the modulation and coding scheme of a second delta value, and wherein the respective types of feedback or the respective delta values corresponding to the set of codepoints of the codebook are a function of the modulation and coding scheme scheduled by the network entity.
