Problems solved by technology

[0005] This problem is more serious in the synchronous multi-link system, which is more prone to the problem of lower transmission efficiency
Specifically, in a synchronous multi-link system, since there may be one or more auxiliary links, and the main / auxiliary link can use a variety of bandwidths, the determined channel bandwidth is limited by multiple conditions, which may further decrease

Embodiment Construction

[0031] As mentioned above, in the existing single-link system of wireless data transmission technology, due to the use environment with interference, the available bandwidth of the transmitter or receiver is often limited due to the existence of interference. In addition, the transmitter and receiver The available bandwidth between the receiving ends may also be different. Therefore, there are various bandwidth combinations, which often results in the use of a smaller bandwidth to transmit data in order to meet the needs of the party with the smaller bandwidth, resulting in lower transmission efficiency. For example, Primary20, Primary40, Primary80 or other bandwidths can be used, respectively. Among them, when the status of the primary 20MHz channel (eg, channel 1) is idle, and the status of other non-primary channels are busy, only "Primary20" can be used, and the available bandwidth at this time is 20MHz. When the status of the main 40MHz channel (such as channels 1 and 2) is...

Abstract

A wireless data transmission method and device, storage medium, and terminal, the method includes: the control of TXOP through TXOP competition;The comparison of the total bandwidth and the total bandwidth of the first reference to determine whether the TXOP competition is restarted; of which, the first available bandwidth with the total bandwidth of one or more links is the sum of the available bandwidth.The invention scheme can be compared by comparison. Only when the total bandwidth is large, it can be transmitted with higher bandwidth, which can effectively 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 terminal. 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 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 continuously use the channel to tra...
