Abstract
Embodiments of this application provide information transmission methods and apparatuses. One method includes: generating, by a first communications device, a physical layer protocol data unit (PPDU) with a bandwidth of X MHz, wherein X>160, some or all fields in the PPDU are rotated in the bandwidth of X MHz by using a rotation factor sequence, the bandwidth of X MHz comprises n bandwidths of Y MHz, the rotation factor sequence comprises n rotation factors, and each of the n bandwidths corresponds to one rotation factor; and sending, by the first communications device, the PPDU to a second communications device.
