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.
