Embodiment Construction
[0064] figure 1 It is a schematic diagram of a wireless network architecture. Such as figure 1 As shown, the wireless network can include multiple nodes
[0065] Among multiple nodes in the wireless network, nodes whose distance is less than a preset distance may be referred to as adjacent nodes.
[0066] figure 1 Take the four nodes A, B, C, and D as an example. Node B is adjacent to A, C, and D. It can receive the signal sent by node A, and can also receive the signals sent by node C and node D.
[0067] Specifically, these nodes may be nodes in a (Mesh network), and each node can not only send and receive information, but also act as a router to forward information to its nearby nodes.
[0068] The foregoing node may be a network device, or a device such as a terminal. Endpoints can be access points (APs) or Meshnetwork nodes.

The application provides a data transmission method, a synchronizing sequence construction method and synchronizing sequence construction devices. The data transmission method comprises the followingsteps: a first node generates a physical layer transmission unit, the physical layer transmission unit comprises a synchronizing sequence; the first node sends the physical layer transmission unit toa second node, wherein the synchronizing sequence included in the physical layer transmission unit is different from the synchronizing sequence in an interference physical layer transmission unit received by the second node. The synchronizing sequence in the physical layer transmission unit actually sent to the second node is different from the synchronizing sequence in the interference physical layer transmission unit received by the second node, the condition that the second node regards the interference physical layer transmission units sent to other nodes as the own, thereby improving theaccuracy rate of the data transmission.
Description
technical field [0001] The present application relates to the field of wireless communication, in particular to a data transmission method, a synchronization sequence construction method and a device. Background technique [0002] In order to better meet user demands for new services such as high-definition video, home theater, and virtual reality (VR), the 60 gigahertz (GHz) millimeter-wave frequency band has gradually become the focus of communication system research in recent years. The 60GHz millimeter-wave frequency band has the characteristics of rich spectrum resources and a wide range of available spectrum. In this frequency band, the data rate can easily exceed Gbps, and the equipment is usually small in size and easy to carry, which provides the possibility to realize wireless communication with larger capacity. Among the current standards, the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11ad stand...
