Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A method, applied to a second communication device, wherein the method comprises:
receiving M first code blocks initially transmitted by a first communication device, wherein the M first code blocks are obtained through polar code encoding on M first to-be-encoded blocks, the M first to-be-encoded blocks carry X information bit blocks, each information bit block is divided into Q information bit subblocks, the Q information bit subblocks of each information bit block are placed into Q first to-be-encoded blocks in the M first to-be-encoded blocks according to a first order, the first order is that each qth information bit subblock of each information bit block is located at ((q−1)*K/Q+1)th to (q*K/Q)th reliable positions of the M first to-be-encoded blocks, q meets 1≤q≤Q, and M meets M=X+Q−1;
receiving M second code blocks retransmitted by the first communication device, wherein the M second code blocks are obtained through polar code encoding on M second to-be-encoded blocks, the Q information bit subblocks of each information bit block are placed into Q second to-be-encoded blocks in the M second to-be-encoded blocks according to a second order, and the second order and the first order meet a mapping relationship; and
combining and decoding the M first code blocks and the M second code blocks to obtain decoded data.
