Polar coder for channel encoding chain for wireless communications

An apparatus for wireless communications, comprising:

• one or more memories;
• and
• one or more processors coupled with the one or more memories and configured, individually or in combination, to:
• receive an input data sequence of a set of bits, wherein the input data sequence includes at least a portion of a set of CRC interleaved information bits, and wherein a number of the set of bits is at least 32;
• encode the input data sequence by a polar encoder to define an intermediate polar encoded data sequence, the polar encoder having a combinational circuit including a plurality of stages that operate in a same clock cycle;
• encode the intermediate polar encoded data sequence for each of the plurality of stages according to a polar encoder factor graph to obtain a final polar encoded data sequence;
• and
• transmit a polar encoded codeword on a control channel based on the final polar encoded data sequence.

A computer-readable medium comprising stored instructions for wireless communications, wherein the instructions are executable by one or more processors to:

• receive an input data sequence of a set of bits, wherein the input data sequence includes at least a portion of a set of CRC interleaved information bits, and wherein a number of the set of bits is at least 32;
• encode the input data sequence by a polar encoder to define an intermediate polar encoded data sequence, the polar encoder having a combinational circuit including a plurality of stages that operate in a same clock cycle;
• encode the intermediate polar encoded data sequence for each of the plurality of stages according to a polar encoder factor graph to obtain a final polar encoded data sequence;
• and
• transmit a polar encoded codeword on a control channel based on the final polar encoded data sequence.
