Abstract: The present invention discloses a data transmission method, apparatus, and system, and an access point. An example 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 some implementations, 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: This application provides a data transmission method. When performing data transmission with a first station in a bandwidth power saving mode by using an operating channel of the first station, an access point performs data transmission with a second station by using an operating channel of the second station. Therefore, even if the operating channel of the first station includes a primary channel, the access point can still perform data transmission with the second station by using another channel. Further, for the access point, although the operating channel of the first station occupies only a part of available bandwidth resources of the access point, the access point can still perform data transmission with the second station by using a remaining channel.

Abstract: A wireless communication apparatus includes, a transceiver module performs data transmission; and a processing module selects a channel whose bandwidth is a to-be-detected bandwidth from a WLAN system. If there is no idle channel, detection is performed again after the to-be-detected bandwidth is reduced.

Abstract: A transmission device includes: an acquiring unit acquires LTF parameters, and acquires a start position I of allocated subcarriers, where the LTF parameters include a frequency domain transform parameter and a time domain transform parameter that are required for generating an LTF sequence; a frequency domain transform unit performs, according to the frequency domain transform parameter and the start position I, a frequency domain transform on an LTF basic sequence to obtain an LTF symbol; a time domain transform unit performs, according to the time domain transform parameter, a time domain transform on the LTF symbol to obtain the LTF sequence; and a sending unit adds the LTF sequence to a first data frame, and sends the first data frame to a second device, so that the second device determines the LTF basic sequence according to the LTF sequence and performs channel estimation according to the LTF basic sequence.
