Abstract

The present invention discloses a data transmission method and apparatus. The method includes: generating, by the primary access point, spatial reuse transmission signaling, the spatial reuse transmission signaling is used to indicate a reuse transmission device of the spatial reuse link to perform data transmission based on the spatial reuse link according to the spatial reuse transmission signaling; sending, by the primary access point, the spatial reuse transmission signaling. According to the data transmission method and apparatus in embodiments of the present invention, mutual interference between the primary link and the spatial reuse link during data transmission can be reduced, and transmission quality can be improved.
