Abstract: Embodiments of the present application disclose a data communication method and apparatus. The data communication method includes: receiving, by a station STA, a wake-up packet sent by an access point AP, where the wake-up packet includes basic service set BSS parameter indication information, the BSS parameter indication information includes BSS parameter change indication information or a target parameter of a primary BSS to which a primary transceiver of the STA currently belongs, and the BSS parameter change indication information is used to indicate whether a critical parameter of the primary BSS changes when the primary transceiver of the STA is in a sleep state; and communicating, by the primary transceiver of the STA, with the AP based on the BSS parameter indication information. The embodiments of the present application can be used to effectively ensure that the primary transceiver of the STA successfully communicates with the AP.
