Claim of US Patent No. 10,342,042

1. A method, wherein the method comprises:generating, by an access point (AP), a data frame, wherein the data frame comprises a high efficiency Wi-Fi Signaling Field 1 (HEW-SIG1) signaling, wherein the HEW-SIG1 signaling comprises first information indicating whether a scheduling transmission is a single-user transmission or a multi-user transmission, and the HEW-SIG1 signaling further comprises a frame structure indication field, and the frame structure indication field indicates a frame structure of the scheduling transmission, wherein the frame structure of the scheduling transmission comprises an uplink structure or a downlink structure, wherein when the first information indicates that the scheduling transmission is the multi-user transmission, the data frame further comprises a high efficiency Wi-Fi Signaling Field 2 (HEW-SIG2) signaling, the HEW-SIG2 signaling is a next signaling of the HEW-SIG1 signaling, and the HEW-SIG2 signaling comprises resource indication information, and when the first information indicates that the scheduling transmission is the single-user transmission, the data frame does not comprise the HEW-SIG2 signaling, and when the scheduling transmission is the multi-user transmission, the HEW-SIG1 signaling further comprises a HEW-SIG2 modulation and coding scheme (MCS) field, and the HEW-SIG2 MCS field indicates a transmission MCS of the HEW-SIG2 signaling; and
sending, by the AP, the data frame.
