    Abstract: The present invention discloses a data transmission method, apparatus, and system, and an access point. The method includes: transceiving data of a data portion in an uplink OFDMA PPDU scheduled by an access point AP on a corresponding allocated frequency resource unit RU, determining one or more fundamental channel units on which the allocated frequency resource unit RU is located, and transceiving at least some fields in a common signaling portion in the uplink OFDMA PPDU on the determined one or more fundamental channels. In this way, one or more fundamental channels for transceiving at least some fields in a common signaling portion in an uplink OFDMA PPDU are determinate, and another user can transceive data on another idle fundamental channel, thereby improving channel utilization. In addition, multiple users can simultaneously transceive data on multiple fundamental channels, thereby improving a service transmission rate.

    Abstract: An HE-LTF transmission method is provided, including: determining, based on a total number NSTS of space-time streams, a number NHELTF of OFDM symbols included in an HE-LTF field; determining a HE-LTF sequence in frequency domain according to a transmission bandwidth and a mode of the HE-LTF field, where the HE-LTF sequence in frequency domain includes but is not limited to a mode of the HE-LTF field sequence that is in a 1× mode and that is mentioned in implementations; and sending a time-domain signal according to the number NHELTF of OFDM symbols and the determined HE-LTF sequence in frequency domain. In the foregoing solution, a PAPR value is relatively low.

    Abstract: The disclosure discloses a high-efficiency short training field sequence generation method, a signal sending method, a signal receiving method, and related apparatuses, where the high-efficiency short training sequence generation method includes: increasing frequency domain density of a frequency domain sequence corresponding to a first high-efficiency short training field sequence to generate a frequency domain sequence with increased frequency domain density; generating a second high-efficiency short training field sequence according to the frequency domain sequence with increased frequency domain density; and using the second high-efficiency short training field sequence as a high-efficiency short training field sequence in a preamble sequence of a data transmission frame in a wireless local area network WLAN. In embodiments of the disclosure, a cycle of a high-efficiency short training field sequence used for performing stage-2 AGC adjustment in the WLAN may be increased, and a maximum CSD value that can be used is further increased.

    Abstract: Embodiments of the present invention disclose a frame transmission method for a wireless local area network and a wireless local area network apparatus, and relate to the field of communications technologies. According to the present invention, in a frame transmission process in a WLAN, a frame sent by a wireless local area network WLAN apparatus is received, and the frame of a particular standard is recognized by detecting a user common signal field included in the frame, so that backward compatibility of a WLAN apparatus is implemented, and hybrid networking of WLAN apparatuses of different standards can be supported, thereby improving flexibility of network deployment, and reducing complexity of networking.
