Methods and apparatus for CRC concatenated polar encoding

An apparatus for wireless communications, comprising:

• a receiver configured to obtain a codeword in accordance with a wireless technology via one or more antenna elements situated proximate the receiver;
• and
• at least one processor coupled with a memory and comprising at least one decoder circuit configured to:
• perform polar inner decoding of the codeword to obtain cyclic redundancy check (CRC) encoded bits to decode the codeword;
• and
• perform CRC outer decoding of the CRC encoded bits to obtain bits of information using only odd-weighted generator polynomials.

A method for wireless communications, comprising:

• obtaining bits of information to be transmitted;
• performing cyclic redundancy check (CRC) outer encoding of the bits of information using only odd-weighted generator polynomials to produce CRC encoded bits;
• performing polar inner encoding of the CRC encoded bits to generate a codeword;
• and
• transmitting the codeword in accordance with a wireless technology across a channel.
