Abstract
Embodiments of the present disclosure relate to a data transmission method and a communications device. The method includes: performing an interpolation operation on a first signal sequence to obtain a second signal sequence, where a length of the second signal sequence is greater than a length of the first signal sequence; mapping the second signal sequence onto a subcarrier to obtain a second signal sequence that is on the subcarrier; performing an inverse fast Fourier transform (IFFT) on the second signal sequence that is on the subcarrier, to obtain a time-domain signal, and transmitting the time-domain signal. According to the embodiments of the present disclosure, a delay deviation can be better resisted.
