Embodiments of the present invention provide an OFDMA transmission method, an access point (AP), and a station. The method comprises: an access point (AP) allocates a same resource unit (RU) to multiple stations, the RU being one or more subcarriers on a frequency domain; and the AP sends, in the same resource unit (RU), downlink data to the multiple stations by using a time division multiplexing manner or a code division multiplexing manner, and the AP sends, in the same resource unit (RU), a pilot symbol to the multiple stations. In this way, an AP can send, in the same resource unit (RU), downlink data and a pilot symbol to multiple stations in a limited time, thereby improving the utilization efficiency of resources. |
