Abstract: 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.

Abstract: An indirect data transmission method may include: calculating an estimated arrival time of a next poll data request of a terminal device according to a receipt time of a poll data request, after the poll data request is received from the terminal device; transmitting data for the terminal device to a cache of a Media Access Control (MAC) layer module at a time point which is a predetermined time length ahead of the estimated arrival time responsive to a determination that there is the data for the terminal device in a network layer module; and transmitting, to the terminal device, an acknowledgement packet indicating that there is the data to be transmitted in the cache of the MAC layer module and the data for the terminal device, responsive to receiving the next poll data request.

Abstract: A method of wirelessly transmitting data by a first electronic apparatus configured to initially perform communication using a first wireless communication manner, includes: the first electronic apparatus determining whether performing data transmission through a second wireless communication manner is required; the first electronic apparatus sending a data transmission request message through the first wireless communication manner when it is determined that performing data transmission through the second wireless communication manner is required; and the first electronic apparatus performing data transmission with a second electronic apparatus through the second wireless communication manner after a data transmission acknowledgement message is received from the second electronic apparatus through the first wireless communication manner. The data transmission request message includes indicating information indicating the first electronic apparatus desires to perform the data transmission using the second wireless communication manner.
