1. A method of wireless communications, comprising:

  • generating a codeword by encoding a sequence of information bits based on a polar code, wherein generating the codeword comprises;

    determining a plurality of locations within the polar code having a rate of 1;

    generating error detection codes based on portions of the sequence of information bits, the portions being defined by the plurality of locations within the polar code having a rate of 1;

    inserting the error detection codes in the sequence of information bits at locations corresponding to the plurality of locations within the polar code having a rate of 1; and

    generating the codeword based on the sequence of information bits, including the error detection codes, and the polar code; and

    transmitting the codeword over a wireless channel.
