Abstract:
An information transmission method includes: modulating, by a terminal device, encoded hybrid automatic repeat request (HARQ) information according to a codebook, to generate HARQ modulation symbols, where the HARQ modulation symbols include at least one non-zero HARQ modulation symbol and at least one zero HARQ modulation symbol, the codebook includes at least two code words, the code words are multi-dimensional complex vectors, and the code words are used to indicate a mapping relationship between a bit and at least two modulation symbols; and sending the HARQ modulation symbols to a network device.
