1. A method, comprising:
encoding, by a processor of an apparatus, a plurality of information bits using a polar code to generate a polar code block (CB); and
performing, by the processor, one or more transmissions of the polar CB using hybrid automatic repeat request (HARQ) by:
performing an initial transmission of the polar CB; and
performing a re-transmission of the polar CB with a re-transmission cyclic redundancy check (ReTX CRC),
wherein the performing of the initial transmission of the polar CB comprises performing the initial transmission of the polar CB with a code block cyclic redundancy check (CB CRC), and
wherein a size of the ReTX CRC is smaller than a size of the CB CRC.
