Abstract: Example polar coding methods and apparatus are described. One example method includes determining a sequence used to code to-be-coded bits. Polar coding is performed on the to-be-coded bits by using the sequence to obtain coded bits. The sequence is used to represent a reliability order of N polarized channels, N is a mother code length of a polar code, and N is a positive integer power of 2.

Abstract: A polar code-based interleaving method and apparatus, to resolve a problem existing in the prior art that when a code length is relatively long, an implementation process of reading a sequence obtained after random interleaving is relatively complex, is provided. The method includes: determining an interleaving matrix based on a target code length M of a polar code; and interleaving, based on the interleaving matrix, encoded bits obtained after encoding of the polar code, to generate interleaved bits.

Abstract: This application relates to the field of communications technologies, and discloses a polar code encoding method and apparatus, to improve accuracy of reliability computation and sorting of polar channels. The method is: obtaining a first sequence used to encode K to-be-encoded bits, where the first sequence includes sequence numbers of N polar channels, and the sequence numbers of the N polar channels are arranged in the first sequence based on corresponding reliabilities of the N polar channels, where K is a positive integer, N is a mother code length of a polar code, N is a positive integer that is a power of 2, and K≤N; selecting sequence numbers of K polar channels from the first sequence in descending order of the reliabilities; and placing the to-be-encoded bits based on the selected sequence numbers of the K polar channels, and performing polar code encoding on the to-be-encoded bits.

Abstract: A method comprises: obtaining a coded bit sequence by performing PC-polar coding on information bits based on first constructor parameters; and sending the coded bit sequence. A check equation of the first constructor parameters includes a first element representing a check-required information bit position and a second element representing a check bit position, the first element corresponds to a first vector (V1) in a generator matrix for PC-polar codes, the second element corresponds to a second vector (V2) in the generator matrix, and if a first Hamming weight (HW1) of V1 is the same as a second Hamming weight (HW2) of V2, then a third Hamming weight (HW3) of an addition modulo 2 vector is greater than HW1 and greater than HW2, or if HW1 is different from HW2, then HW3 is greater than a smaller one of the HW1 and HW2.
