Abstract
The present disclosure relates to polar encoding methods and apparatus. One example method includes obtaining locations of information bits and frozen bits based on a reliability order of polar channels, where reliability of a polar channel corresponding to the information bits is higher than reliability of a polar channel corresponding to the frozen bits, performing cyclic redundancy check (CRC) encoding on an information block, mapping bits obtained after the CRC encoding to the information bits, determining at least one bit of the frozen bits as a check frozen bit, where a value of the check frozen bit is determined based on values of P information bits that are in information bits prior to the check frozen bit and that meet a preset condition, and performing polar encoding on the information bits, the check frozen bit, and a frozen bit other than the check frozen bit.
