Classification: CPC H | IPC H

Claim 7:
8. The method according to claim 7, wherein the method further comprises:
obtaining, by the receive end, incremental redundant bits that are transmitted by a transmit end for a second time or some of the k information bits and the incremental redundant bits that are transmitted by the transmit end;
combining, by the receive end, the incremental redundant bits to an end of the first codeword to form a second codeword; and
decoding, by the receive end, the second codeword based on a second check matrix, wherein the second check matrix is a submatrix of the first ((n—k)/Z+h) rows and the first (n/Z+h) columns in the check matrix H, a code rate of the second check matrix is equal to a second transmission code rate, and h is an integer greater than j and less than or equal to Q.
