    Abstract: Embodiments of this application provide a data transmission method and apparatus. A method at a transmit end includes: obtaining a first sequence, where the first sequence includes a first sub-sequence and a second sub-sequence; mapping the first sub-sequence into K third sub-sequences based on a preset sequence group; performing differential coding and phase modulation on the second sub-sequence to obtain a fourth sequence whose length is K′; obtaining K fifth sub-sequences based on the K third sub-sequences and the K′ fourth sub-sequences; and outputting a second sequence including the K fifth sub-sequences. A method at a receive end includes: obtaining a second sequence including K fifth sub-sequences, and detecting the K fifth sub-sequences based on a preset sequence group to obtain a first sub-sequence; and performing differential demodulation based on the first sub-sequence to obtain a second sub-sequence, so that a first sequence is determined.

    Abstract: A data modulation method includes dividing, by a terminal device, to-be-sent data into N bit groups, wherein N≥2 and N is an integer. The method also includes generating, by the terminal device, N complex symbol groups. An ith complex symbol group is obtained by processing an ith bit group based on a mapping rule corresponding to the ith bit group. The mapping rule corresponding to the ith bit group is determined based on at least a group identity of the ith bit group and a first parameter. The first parameter includes at least one of a pilot parameter, a hopping identity, a terminal device identity, a layer index of a non-orthogonal layer, or a hopping offset. The N bit groups correspond to at least two different mapping rules, 0≤i≤N−1, and i is an integer. The method further includes sending, by the terminal device, the N complex symbol groups.
