1. A method for wireless communications at a first wireless device, comprising:
partitioning a set of information bits into a plurality of subsets of bits corresponding to a plurality of polarization levels based at least in part on one or more mutual information polarization functions that are representative of respective relationships between a coding rate of a channel and respective coding rates of the plurality of polarization levels, wherein the partitioning comprises:
allocating a first quantity of bits to a first subset of bits, wherein the first quantity of bits is determined based at least in part on a first coding rate determined using a first mutual information polarization function; and
allocating a second quantity of bits to a second subset of bits, wherein the second quantity of bits is determined based at least in part on a second coding rate determined using a second mutual information polarization function;
encoding the first subset of bits for a first polarization level of the plurality of polarization levels according to a first channel coding scheme having the first coding rate;
encoding the second subset of bits for a second polarization level of the plurality of polarization levels according to a second channel coding scheme having the second coding rate;
performing a polarizing transform using the encoded first subset of bits for the first polarization level and the encoded second subset of bits for the second polarization level to obtain a set of output bits corresponding to the set of information bits and
transmitting the set of output bits to a second wireless device.
