1. A data transmission method, comprising:
generating, by a network device, a multiple user physical layer protocol data unit (MU PPDU); and
sending, by the network device, the MU PPDU to a station, wherein a bandwidth of the MU PPDU is greater than 20 MHz, and the bandwidth comprises a first sub-bandwidth and a second sub-bandwidth, wherein the first sub-bandwidth carries a first content channel of an extremely high throughput-signaling (EHT-SIG) field of the MU PPDU, and the second sub-bandwidth carries a second content channel of the EHT-SIG field; and
wherein a first universal signal (U-SIG) overflow field carried in a field of first (i−1) information bits of the first content channel is the same as a second U-SIG overflow field carried in a field of first (i−1) information bits of the second content channel, and an ith information bit to a jth information bit of the first content channel carry a first resource unit allocation indication field and a first user field, wherein both i and j are positive integers, and 1<i<j.
