    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: A method for determining time to live (TTL) of a path of a node including receiving a routing control packet, which includes a first link quality indicating a link quality of a path from the neighbor node to a source node transmitting the routing control packet, from a neighbor node of the node, acquiring a third link quality indicating a link quality of a path from the node to the source node according to a second link quality indicating a link quality of a path from the node to the neighbor node and the first link quality, and determining the TTL of the path from the node to the source node according to the third link quality may be provided. Accordingly, the TTL of the path can be determined more accurately according to a link quality of the path, thereby contributing to ensuring performance and stability of a routing algorithm.

    Abstract: A method, apparatus and/or system of selecting a routing in an asymmetric link, in which an arbitrary intermediate node of the at least one intermediate node receives routing request information including a first link quality for a path from the source node to the arbitrary neighbor node from an arbitrary neighbor node of the arbitrary intermediate node, acquires a second link quality for a path between the arbitrary intermediate node and the arbitrary neighbor node, acquires a third link quality based on the first and second link qualities, updates the first link quality in the routing request information with the third link quality, and broadcasts an updated routing request information to other neighbor node for the destination node to determine at least one of a desirable forward path or a desirable backward path from the source node to the destination node, may be provided.
