[0093] In a first embodiment, the present application provides a Wi-Fi chip, and the Wi-Fi chip includes a processor and multiple FIFO queues. The processor can be used to schedule, process or control the messages to be transmitted, for example, to schedule the messages to one of the multiple FIFO queues, and control the messages in the multiple FIFO queues to be output sequentially according to the priority order of the queues .
[0094] Wherein, the above-mentioned plurality of FIFO queues may include four first FIFO queues and N second FIFO queues, and the four first FIFO queues include voice stream VO queues, video stream VI queues, best-effort stream BE queues, and background streams BK queue. The N second FIFO queues are newly added private FIFO queues, and are used for buffering data sensitive to transmission delay or messages that the user wishes to process preferentially. Wherein, the N second FIFO queues respectively correspond to which business types of data are s...

[0129] In the second embodiment, the present application provides an AP device, and the AP device includes the Wi-Fi chip in the first embodiment above.
[0130] Optionally, the AP device can establish a wireless connection with one or more terminal devices (that is, STA devices) through the Wi-Fi protocol, that is, establish a Wi-Fi transmission channel, and then the connection between the AP device and one or more STA devices They can transmit packets to each other on the Wi-Fi transmission channel. In the embodiment of the present application, in the downlink direction of message transmission from the AP device to the STA device, the AP side may implement putting the message into FIFO queues of different priorities for scheduling processing.
[0131] Exemplarily, refer to Figure 11 As shown, in the downlink direction in which the AP device 41 forwards the message to the terminal device 42, if the AP device 41 obtains the message to be forwarded, the AP device can first id...

[0134] In the third embodiment, the present application provides a terminal device supporting the Wi-Fi protocol, also called STA device, and the terminal device includes the Wi-Fi chip in the first embodiment above. The terminal device can establish a wireless connection with the AP device through the Wi-Fi protocol, that is, establish a Wi-Fi transmission channel, and then the terminal device and the AP device can exchange messages on the Wi-Fi transmission channel. In the embodiment of the present application, in the uplink direction of message transmission from the STA device to the AP device, the STA side may implement putting the message into FIFO queues of different priorities for scheduling processing.
[0135] Exemplarily, refer again to Figure 11 As shown, in the uplink direction in which the terminal device 42 sends messages of various service types to the AP device 41, if the terminal device 42 obtains the message to be forwarded, the terminal device 42 can first ...
