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.

Claim (Index 7):
A data transmission apparatus, for transmitting an Orthogonal Frequency Division Multiple Access (OFDMA) uplink physical layer convergence protocol data unit (PPDU), the apparatus comprising:\n a memory having a storage medium, wherein the memory stores a data transmission program; and a processor that is connected to the memory, the processor invokes the data transmission method program stored in the memory, and executes the following: in a communication channel having a channel bandwidth that is a multiple of 20 MHz channels, configuring an uplink OFDMA PPDU that comprises a common signaling portion and a data portion with a frequency resource unit (RU) within the bandwidth being allocated for the data portion and that is located:\n in one 20 MHz channel and is smaller than 20 MHz, or \n in multiple 20 MHz channels and is smaller than the multiple 20 MHz; and \n configuring the common signaling portion of the PPDU to include at least one of a legacy preamble and an HE-SIG-A; sending, by the STA, the data portion in the OFDMA PPDU on the allocated RU; and sending, by the STA, the at least one of the legacy preamble and the HE-SIG-A in the common signaling portion of the uplink OFDMA PPDU only on the one or multiple 20 MHz channels where the allocated RU is located.
