This application relates to the field of wireless communications technologies, and discloses
a polar code encoding method and apparatus, to improve accuracy of reliability calculation
and ordering for polarized channels. The method includes: obtaining a first sequence used
to encode K to-be-encoded bits, where the first sequence includes sequence numbers of N
polarized channels, the sequence numbers of the N polarized channels are arranged in the
first sequence based on reliability of the N polarized channels, K is a positive integer, N is a …
