Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0032] refer to figure 1 , figure 1 It is a network architecture diagram of a wireless communication system. A wireless communication system includes at least one station and at least one access point (access point, AP for short). For example: the wireless fidelity communication system includes: STA1, STA2, STA3 and AP. Before the station establishes a connection with any access point, the station selects a frequency point to connect to the access point through passive scanning or active scanning. The frequency point is the center frequency of the frequency range. A frequency point corresponds to a channel. The access point establishes a connection. When the station establishes a communication connection with the access point, the stati...

Abstract

The embodiment of the invention discloses a data transmission method and device, a storage medium and a wireless node, and belongs to the field of wireless communication. The method comprises the following steps: in an idle state, updating a sending waiting time length and the number of data frames to be sent; if the duration value of updating, sending and waiting is greater than or equal to the duration threshold value or the number of the data frames to be sent is greater than or equal to the first aggregation number threshold value, executing a channel competition process; if the channel competition is successful, determining a starting moment and an ending moment of a TXOP period; sending the cached data frames in an aggregation mode in the TXOP period; if the data transmission is successful or partially successful, continuing to update the transmission waiting duration and the number of the data frames to be transmitted in an idle state; if the upper limit of the TXOP period is not reached, updating the number of the data frames to be sent, if the number of the data frames to be sent is larger than or equal to the second aggregation number threshold value, sending the cached data frames in the TXOP period. The purposes of controlling data transmission time delay and improving transmission efficiency can be achieved.

Description

technical field [0001] The present application relates to the field of wireless communication, and in particular to a data transmission method, device, storage medium and wireless node. Background technique [0002] The 802.11 protocol stipulates that a station (station, referred to as STA) obtains the right to use the channel through channel competition, and the station that successfully competes for the right to use the channel sends an RTS (require to send, request to send) frame to apply for a TXOP (transmit opportunity, transmission Opportunity) period, the station is also called the holder of the TXOP period (TXOP holder). Then the station sends data within the TXOP period. After the data is sent, it sends a CF-END (contention-free periodend, end of contention-free period) frame to indicate TXOP The cycle ends. After the TXOP cycle ends, all stations wait for at least one DIFS (DCF interframe space, distributed coordination function interframe space) before re-executi...
