1. A polar code encoding method, comprising:
obtaining, by an encoding apparatus, K to-be-encoded bits, a mother code length N, and a first sequence, wherein the first sequence comprises sequence numbers of N polarized subchannels, the sequence numbers of the N polarized subchannels are arranged in the first sequence based on reliability of the N polarized subchannels, N=2n, K≤N, N is greater than or equal to 32, and K, n, and N are positive integers;
determining, based on the first sequence, K polarized subchannels used to contain the K to-be-encoded bits, and performing polarization encoding on the K to-be-encoded bits to obtain an encoded bit sequence;
performing rate matching on the encoded sequence to obtain a rate-matched sequence; and
outputting the rate-matched sequence;
wherein the first sequence is a sequence Q5_8192 or a subsequence of the sequence Q5_8192.
