1. A method, applied to a first communication device, wherein the method comprises:
obtaining X information bit blocks, wherein each information bit block comprises K information bits, each information bit block is divided into Q information bit subblocks, and each information bit subblock is a binary sequence whose length is K/Q;
placing the Q information bit subblocks of each information bit block into Q first to-be-encoded blocks in M first to-be-encoded blocks according to a first order, wherein 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;
separately performing polar code encoding on the M first to-be-encoded blocks to obtain M first code blocks;
sending the M first code blocks to a second communication device;
when retransmission is required after sending the M first code blocks, placing the Q information bit subblocks of each information bit block into Q second to-be-encoded blocks in M second to-be-encoded blocks according to a second order, wherein the second order and the first order meet a mapping relationship;
separately performing polar code encoding on the M second to-be-encoded blocks to obtain M second code blocks; and
sending the M second code blocks to the second communication device.
