    Abstract: Embodiments of this application relates to a multi-link communication setup method and a related apparatus. The method includes: a non-AP MLD sends an association request frame on a first link, to request multi-link setup. An AP MLD returns an association response frame on the first link, to notify whether multi-link setup succeeds. The AP MLD sets a second status code field of a multi-link element of the association response frame to a newly defined value, to indicate that a cause why a link is not accepted is that the first link is not accepted. This application is applied to a WLAN system that supports a next generation Wi-Fi protocol of 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and other 802.11 series protocols; and for another example, a next generation protocol of 802.11be: Wi-Fi 8.

    Abstract: This application provides a communications method and a communications apparatus. A first station in a first multi-link device sends first information to a second multi-link device, where the first information is used to indicate a frequency at which how often a station in a power saving mode in the first multi-link device receives a beacon frame. In this way, the second multi-link device may learn about, based on the first information, how often a frequency at which a station in the first multi-link device receives a beacon frame, thereby helping the second multi-link device effectively manage a cache service of each station in the first multi-link device and manage a data buffer space.

    Abstract: This application provides a channel access method and an apparatus, and relates to the field of communication technologies, to resolve a problem that it is difficult for a long range communication device to access a channel, and communication efficiency is low. The method includes: A first device detects a channel status in first duration. If a channel is in an idle state, M is subtracted from a value of a first counter, where M is a positive integer greater than 1. If the value of the first counter is greater than 0, the first device detects the channel status in next first duration; or if the value of the first counter is less than or equal to 0, the first device transmits data through the channel.

    Abstract: This application provides a data transmission method and a related apparatus. The method includes: A network device generates a first physical layer protocol data unit PPDU. The first PPDU includes a first universal-Signaling field U-SIG field and a first extremely high throughput-Signaling field EHT-SIG field, a sum of a quantity of information bits of the first U-SIG field and a quantity of information bits of the first EHT-SIG field is less than or equal to 78 information bits, and at least one of the first U-SIG field and the first EHT-SIG field includes an identifier indication field, where the identifier indication field is used to uniquely identify one station. The network device sends an encoded first PPDU to a station.

    Abstract: This application discloses a multi-link communication probe request method and apparatus. The method includes: a non-access point multi-link device (non-AP MLD) generates a probe request frame, and sends the probe request frame to an access point multi-link device (AP MLD), and the AP MLD receives the probe request frame, and generates a probe response frame and sends to the non-AP MLD. The probe request frame includes a first multi-link element (MLE) that is used to request link information of the AP MLD and that includes a first link information field. The first link information field includes a first field. The first field indicates that the non-AP MLD requests the AP MLD to feed back complete information or partial information of a first link. The first link information field corresponds to the first link.

    Abstract: Disclosed are a physical layer (PHY) protocol data unit (PPDU) transmission method and a related apparatus. The method includes: generating a PPDU, where the PPDU includes a universal signal field (U-SIG), and the U-SIG includes a subfield indicating that the PPDU is a null data packet (NDP); and sending the PPDU. In this way, a beamformee (Bfee) that receives the NDP can identify the NDP earlier. This helps improve efficiency of reading the NDP by the Bfee. The PPDU is an NDP used for a standard after 802.11ax. In a scenario in which wireless communication is performed by using the standard (for example, 802.11be) after 802.11ax, the Bfee can perform channel estimation based on the NDP.

The method includes: generating a physical layer protocol data unit (PPDU), where the PPDU includes a short training field, a length of a frequency domain sequence of the short training field is greater than a first length, and the first length is a length, for example, 2048, of a frequency domain sequence of a short training field that is transmitted over a 160 MHz-bandwidth channel, and sending the PPDU over a target channel, where a bandwidth of the target channel is greater than 160 MHz. According to embodiments of this application, a larger actual channel bandwidth can be achieved, and backward compatibility is implemented.
