1. A polar code coding method, comprising:
obtaining, by a coding apparatus, K to-be-coded bits;
determining a mother code length N;
determining a first sequence from at least one polar code construction sequence based on a coding parameter, wherein the first sequence consists of serial numbers of L polarized channels, the serial numbers are arranged in an ascending or a descending order of reliability of the polarized channels, K, L and N are positive integers, L is equal to K or N, K is less than or equal to N, and N is one of the following values: 32, 64, 128, 256, 512, 1024;
placing the K to-be-coded bits based on serial numbers of K polarized channels determined based on the first sequence, and performing polar coding on the to-be-coded bits, to obtain a coded bit sequence; and
outputting the coded bit sequence.
