Abstract

A data transmission method includes: generating a first data packet, where a signaling field in the first data packet includes bandwidth information and space-time stream information, the bandwidth information is used to indicate first bandwidth, and the space-time stream information is used to indicate k first space-time stream quantities corresponding to k receive ends, where k≥1; and sending the first data packet to the k receive ends, where a maximum value of the first bandwidth is greater than 160 MHz, and/or the k first space-time stream quantities meet a preset condition, where the preset condition includes: when k=1, a maximum value of the first space-time stream quantity indicated by the space-time stream information is greater than 8, and when k>1, a maximum value of a sum of the k first space-time stream quantities is greater than 8.
