The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

The initial access method provided by the embodiments of the present disclosure is applied to a wireless local area network communication system including a data sending device and a data receiving device. The data sending device and the data receiving device can be a station (Station, STA) or an access point (Access Point, AP). The data sending device and the data receiving device perform the forward transmission and back transmission of data through the wireless local area network.

Among them, the STA involved in this disclosure can be understood as a user terminal in a wireless local area network. The user terminal can be referred to as user equipment (UE), mobile station (MS), and mobile terminal (MT). ), etc., are devices that provide users with voice and/or data connectivity. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, and the like. At present, some examples of terminals are: smart phones (Mobile Phone), pocket computers (Pocket Personal Computer, PPC), handheld computers, personal digital assistants (Personal Digital Assistant, PDA), notebook computers, tablet computers, wearable devices, Internet of Things (IoT) client or in-vehicle equipment, etc.
