1. A data transmission method of a transmission device, the method comprising:
initiating a first transmission mechanism by allocating corresponding Orthogonal Frequency Division Multiple Access (OFDMA) sub-channels to respective one or more 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;
transmitting data in the current data transmission scenario to the respective one or more target neighbor devices through the OFDMA sub-channels; and
performing transmission mechanism switching operation to initiate a second transmission mechanism based on a determination that the transmitting of the data in the current data transmission scenario is completed.
