Abstract: This application relates to the field of wireless fidelity Wi-Fi technologies, and in particular, to a groupcast feedback method, an apparatus, and a system, to send a feedback in a groupcast transmission scenario. According to the method, an access point sends a groupcast data frame and a groupcast feedback trigger frame. The groupcast feedback trigger frame is used to schedule a plurality of stations in a groupcast group to indicate whether the groupcast data frame is correctly decoded.
