Abstract
Example Polar code rate matching methods and apparatus are described. One example method includes determining a first index set corresponding to N to-be-encoded bits. The first index set includes indexes of Z polarized channels on which forced frozen bits are placed. The Z polarized channels are a subset of N polarized channels corresponding to the N to-be-encoded bits, N=2n, Z<N, and n and Z are positive integers. A first codeword with a length of N is obtained by performing Polar coding on the N to-be-encoded bits. Rate matching is performed on the first codeword based on the first index set, to obtain a second codeword with a length of M, where M<N and M is a positive integer. The second codeword is sent with a length of M.
