1. An apparatus for wireless communications at a user equipment (UE), comprising:
at least one processor;
at least one memory coupled with the at least one processor; and
instructions stored in the at least one memory and executable by the at least one processor to cause the apparatus to:
encode channel state feedback information associated with the UE to compress the channel state feedback information to a first encoding output associated with a first dimensional space;
apply entropy coding to the first encoding output of the channel state feedback information, wherein the entropy coding transforms the first encoding output to a second encoding output associated with a second dimensional space that is smaller than the first dimensional space of the first encoding output; and
transmit a channel state feedback message comprising the second encoding output;
wherein the instructions are further executable by the at least one processor to cause the apparatus to perform one or more of:
(i) receive an indication of a size of the first dimensional space, wherein the UE encodes the channel state feedback information based at least in part on the indication;
(ii) receive an indication of a size of the second dimensional space, wherein the UE applies the entropy coding to the first encoding output based at least in part on the indication; and
(iii) receive an indication of an entropy coding technique; and apply the entropy coding to the first encoding output based at least in part on the indication.
