Claim 0:
1. A polar code encoding method implemented by a polar code encoding apparatus, comprising:
obtaining, by an input interface circuit of the polar code encoding apparatus, K information bits to be encoded, wherein K is a positive integer;
determining, by a processor of the polar code encoding apparatus, K information bit positions;
mapping, by the processor of the polar code encoding apparatus, the K information bits to be encoded to the K information bit positions to obtain a first bit sequence, wherein a length of the first bit sequence is N, N is a positive integer power of 2, and the first bit sequence comprises fixed bits and the K information bits to be encoded;
determining, by the processor of the polar code encoding apparatus, a second bit sequence based on the first bit sequence and an upper triangular matrix, wherein the upper triangular matrix is a matrix having N rows and N columns;
performing, by the processor of the polar code encoding apparatus, polar code encoding on the second bit sequence to obtain an encoded sequence; and
transmitting, by the output interface circuit of the polar code encoding apparatus, the encoded sequence to a device to be decoded.
