Problems solved by technology
[0004] However, due to the crosstalk in the data link established between the router and the device, the data transmission between adjacent links will have data crosstalk, which in turn causes the risk of packet loss in the data transmission between the router and the device.

This application relates to a data transmission method, system and terminal based on wifi6. If the router does not receive a data packet feedback response message within a preset period of time after the data packet is sent, the second is to determine that the data packet sent to the first device is lost. Determine the authority level of the first device; if the authority level is greater than the preset value, then set at least one data packet retransmission window, and resend the data packet within the data packet retransmission window; or, if the authority level is not greater than the preset value, then Detect whether the feedback information from the second device is received, and send the data packet to the first device through the second device according to the feedback information. When the router communicates with multiple devices and the data link crosstalk causes data packet loss, if the first device has a higher authority, the data packet retransmission window is used to retransmit the data packet. If the authority is disclosed, it will be forwarded through other devices, thereby reducing the risk of packet loss during data transmission between the router and multiple devices while ensuring device communication.
Description
technical field [0001] The present application relates to the field of data transmission, in particular to a wifi6-based data transmission method, system and terminal. Background technique [0002] Wi-Fi 6 (formerly known as: 802.11.ax) is the sixth generation of wireless network technology and is the name of the Wi-Fi standard. It is a wireless local area network technology created by the Wi-Fi Alliance based on the IEEE 802.11 standard. Wi-Fi 6 mainly uses technologies such as OFDMA and MU-MIMO. MU-MIMO (Multiple User Multiple Input Multiple Output) technology allows routers to communicate with multiple devices at the same time instead of sequentially. MU-MIMO allows routers to communicate with four devices at once, and Wi-Fi 6 will allow communication with up to eight devices. [0003] The data communication method based on Wi-Fi 6 allows the router to communicate with multiple devices, so in terms of data transmission, it avoids the problem of queuing for data transmis...
