Abstract: In a data transmission method, a station in a wireless network receives a trigger frame sent by an access point of the wireless network. The trigger frame includes an identifier of a target frequency domain resource unit RU allocated to the station. The station sends an uplink orthogonal frequency division multiple access physical layer protocol data unit OFDMA PPDU, where a data part of the OFDMA PPDU is sent in the target RU, and a common physical layer preamble of the OFDMA PPDU is sent in one or more fundamental channels in which the target RU is located. The station then receives from the access point an acknowledgement frame, which is sent in a response RU that is located in the one or more channels of the target RU.

Abstract: This application discloses a multi-link establishment method and a related device. A multi-link association response frame carries radio bitmap information, to indicate an AP allowed to be associated with a radio of a STA MLD or a link allowed to be established by using a radio of a STA MLD, so that the radio subsequently switches between different APs or links. The multi-link association response frame carries link establishment status information, to indicate a link establishment status of each link that the STA MLD requests to establish, so that multi-link establishment is more flexible. The multi-link association response frame carries reassociation information, to indicate whether each parameter in association configuration information is reserved, so that a problem that signaling overheads are relatively large due to a reassociation operation is avoided. It can be learned that, in the multi-link establishment method, the foregoing information is carried to improve multi-link establishment flexibility.

Abstract: This application relates to the field of wireless fidelity technologies, and in particular, to a resource indication method, an access point, and a station. The method includes: An access point generates a PPDU, and sends the PPDU, where the PPDU comprises a preamble puncturing information field; and where when the PPDU is in non-orthogonal frequency division multiple access (non-OFDMA) transmission mode, the preamble puncturing information field is used to indicate a puncturing status of an entire bandwidth corresponding to the PPDU; when the PPDU is in an orthogonal frequency division multiple access (OFDMA) transmission mode, the preamble puncturing information field is used to indicate a puncturing status of 80 MHz corresponding to a frequency domain fragment.

Abstract: Embodiments of this disclosure disclose a multi-link communication method and a related apparatus. In a scenario in which simultaneous transmission and reception over a plurality of links is not supported, a multi-link device first sends a first physical layer protocol data unit (PPDU) over a first link, and then sends a second PPDU over a second link through channel contention, where an end time of the second PPDU is not later than an end time of the first PPDU. The method not only ensures fairness of multi-link access, but also can reduce an idle rate of the plurality of links.

Abstract: This application relates to the field of wireless communication, and in particular, to an orthogonal frequency division multiple access (OFDMA) hybrid transmission method and apparatus. The method includes: An access point may send a trigger frame, to schedule stations supporting different standards to perform OFDMA uplink transmission, where the stations supporting different standards support different bandwidth sizes. The stations receiving the trigger frame send a trigger-based physical layer protocol data unit (TB PPDU) to the access point, where the TB PPDU includes uplink data of the stations supporting different standards, and the stations of different standards may send the uplink data by using RUs located in bandwidths respectively supported by the stations. Therefore, a channel can be fully utilized to improve frequency domain resource utilization.
