Provided are a data transmission method and a data transmission device, the data transmission method comprising: when a current data transmission scene is a preset data transmission scene, allocating a corresponding OFDMA sub-channel for each target neighbor device in a wireless personal region network; and transmitting the OFDMA sub-channel corresponding to the data distribution in the preset data transmission scene to each target neighbor device through the sub-channel. According to the method, an SOC system under a wireless local region network and a wireless personal region network supports an OFDMA transmission mechanism, the OFDMA transmission mechanism is provided under a data transmission scene with a large data volume, the data transmission rate is increased, and the data transmission time is saved. 提供了一种数据传输方法和数据传输装置，数据传输方法包括：在当前的数据传输场景为预设数据传输场景时，为无线个域网中的各目标邻居设备分配对应的OFDMA子通道；通过所述子通道向各目标邻居设备传输所述预设数据传输场景下的数据分配对应的OFDMA子通道。该方法使得无线局域网和无线个域网下的SOC系统中支持OFDMA传输机制，在数据量较大的数据传输场景下提供OFDMA传输机制，提高数据传输的速率，节省数据传输的时间
