This application discloses an encoding method, an apparatus, a communications device, and a communications system. The method includes: encoding an input bit sequence by using a low density parity check (LDPC) matrix, where the LDPC matrix is obtained based on a lifting factor Z and a base matrix, and the base matrix includes row 0 to row 6 and column 0 to column 16 in one of matrices shown inFIG. 3b-1 to FIG. 3b-8, or the base matrix includes row 0 to row 6 and some columns of column 0 to column 16 in any matrix shown inFIG. 3b-1 to FIG. 3b-8. The encoding method, the apparatus, the communications device, and the communications system in this application can support an encoding requirement for information bit sequences with a plurality of lengths.
