Claim 0:
1. An method applied in a wireless local area network (WLAN), the method comprising:
generating, by an apparatus, a physical protocol data unit (PPDU) for a downlink multiple-user transmission, wherein the PPDU includes: a legacy preamble, a high efficiency Wi-Fi Signaling Field 1 (HEW-SIG1), a high efficiency Wi-Fi Signaling Field 2 (HEW-SIG2) adjacent to the HEW-SIG1 in the PPDU, and a data portion, and wherein the HEW-SIG1 comprises a HEW-SIG2 modulation and coding scheme (HEW-SIG2 MCS) field, the HEW-SIG2 MCS field indicates a transmission modulation and coding scheme (MCS) used to transmit the HEW-SIG2, the HEW-SIG1 further comprises a frame structure indication field, the frame structure indication field indicates whether a frame structure of a scheduling transmission is an uplink structure or a downlink structure, and the HEW-SIG2 comprises resource indication information; and
sending, by the apparatus, the PPDU.
