The disclosure provides a data transmission method and a data transmission device. The data transmission method includes allocating corresponding Orthogonal Frequency Division Multiple Access (OFDMA) sub-channels to respective target neighbor devices in a wireless personal area network (WPAN) based on a determination that a current data transmission scenario of the WPAN is a specific data transmission scenario and transmitting data in the preset data transmission scenario to the respective target neighbor devices through the OFDMA sub-channels. Moreover, according to the data transmission method, an OFDMA transmission mechanism is supported in a SoC system under a wireless local area network and the wireless personal area network, and the OFDMA transmission mechanism is provided in data transmission scenarios with a large amount of data, thereby improving the data transmission rate and saving the data transmission time.
