1. A data transmission method, wherein the method is used on a transmit end and comprises:
generating a first data packet, wherein a signaling field in the first data packet comprises bandwidth information and space-time stream information, the bandwidth information indicating a first bandwidth, and the space-time stream information indicating k first space-time stream quantities corresponding to k receive ends, wherein k is larger than 1; and
sending the first data packet to the k receive ends, wherein
a maximum value of the first bandwidth is greater than 160 MHz, and the k first space-time stream quantities meet a preset condition, wherein the preset condition comprises a maximum value of a sum of the k first space-time stream quantities is greater than 8;
wherein a target transmission resource comprises m first transmission resources successively arranged in a frequency domain, and n second transmission resources successively arranged in the frequency domain, and m>1, and n>1;
wherein the signaling field further comprises indication information, the indication information comprising first allocation information of each first transmission resource in the target transmission resource and second allocation information of each second transmission resource in the target transmission resource;
wherein the first allocation information of each first transmission resource indicates at least one first resource unit (RU) obtained by dividing the first transmission resource, and a receive end to which each first RU is allocated; and
wherein the second allocation information of each second transmission resource indicates whether the second transmission resource is allocated to any one of the k receive ends, and indicates a receive end to which the second transmission resource is allocated when the second transmission resource is allocated to any receive end.
