Abstract

A wireless data transmission method and device, storage medium, and STA, the method comprising: determining an original backoff window; based on the original backoff window, randomly determining an initial value of the reciprocal, and using the initial value of the reciprocal to perform the reciprocal; Reciprocal time interval, if the state of the main channel is idle, then determine the available total bandwidth, and determine the reciprocal reduction step in the reciprocal time interval according to the available total bandwidth; according to the reciprocal reduction step, at each reciprocal An updated reciprocal value is obtained at a time interval; when the updated reciprocal value is less than or equal to zero and the control right of the TXOP is obtained, the TXOP is used to send the wireless data. The present invention can help to increase the probability that a larger available total bandwidth is selected, so that there is an opportunity to use a higher bandwidth for transmission to improve the data transmission efficiency of the system.

Description

technical field

[0001] The present invention relates to the field of communication technologies, and in particular to a wireless data transmission method and device, a storage medium, and a station. Background technique

[0002] In the traditional Institute of Electrical and Electronics Engineers 802.11 (Institute of Electrical and Electronics Engineers 802.11, IEEE802.11) protocol, only a single-link system is defined, such as a wireless local area network (Wireless Local Area Network, WLAN) protocol. With the development of technology, the transmission mode of synchronous multi-link system is discussed in 802.11be.

[0003] In wireless data transmission technology, transmission opportunity (Transmission Opportunity, TXOP) competition is an important content of wireless channel access, which consists of an initial time and a maximum duration (TXOP limit). Specifically, the TXOP can be obtained through competition or allocation, and the station that obtains the TXOP can con...
