Claim 0:
1. A wireless local area network data transmission method, comprising:
generating, by an access point, a physical layer protocol data unit (PPDU) of a wireless local area network, wherein the generated PPDU comprises a Physical Layer Convergence Protocol (PLCP) header domain and a data domain, wherein the PLCP header domain comprises a preamble and a control domain, wherein the control domain carries identifier information of the access point, an identifier of at least one station, and duration information, wherein the duration information in the PLCP header domain is for network allocation vector (NAV) setting, wherein the NAV is for protecting transmission of one or more PPDUs subsequent to the generated PPDU in an orthogonal frequency division multiple access (OFDMA) transmission opportunity (TXOP), and wherein a duration indicated by the duration information in the PLCP header domain includes a transmission duration of the one or more PPDUs subsequent to the generated PPDU in the TXOP; and
sending, by the access point, the generated PPDU;
wherein the data domain of the generated PPDU is transmitted via OFDMA technology, and wherein the data domain of the generated PPDU carries a downlink medium access control protocol data unit (MPDU), and the MPDU comprises a medium access control (MAC) header domain, wherein the MAC header domain of the downlink MPDU carried in the data domain further comprises an OFDMA control field and a frame control field.
