Claim 12:
13. The method according to claim 12, further comprising:
receiving M third code blocks retransmitted by the first communication device, wherein the M third code blocks are obtained through polar code encoding on M third to-be-encoded blocks, the Q information bit subblocks of each information bit block are placed into Q third to-be-encoded blocks in the M third to-be-encoded blocks according to a second order, and the second order used in the third to-be-encoded blocks is different from the second order used in the second to-be-encoded blocks;
in response to a sum of channel capacities of two times of transmission performed by the first communication device being less than the code rate R, and a sum of channel capacities of three times of transmission performed by the first communication device being greater than or equal to the code rate R, obtaining, through decoding, k1 information bit subblocks [a1, a2, . . . , aki] comprised in each information bit block carried in the M first to-be-encoded blocks and k2 information bit subblocks [aQ, aQ−1, . . . , aQ−k2+1] comprised in each information bit block carried in the M second to-be-encoded blocks, wherein k1 and k2 meet k1+k2<Q;
obtaining, through decoding, k3 information bit subblocks [A1, A2, . . . , Ak3] comprised in information bit block carried in the M third to-be-encoded blocks, wherein k3 meets 1≤k3≤Q, and k1, k2, and k3 meet k1+k2+k3≥Q;
obtaining, according to the mapping relationship between the first order and the second order, k3 information bit subblocks [ak1+1, ak1+1, . . . , aQ−k2] corresponding to each k3 information bit subblocks before mapping; and
obtaining Q information bit subblocks [a1, a2, . . . , aQ] comprised in each information bit block.
