    Abstract: A non-AP MLD or a first STA in the non-AP MLD generates a first frame. The first frame includes indication information for indicating padding duration for a channel switch delay in an initial control frame. The padding duration is determined based on duration of a control response frame. The non-AP MLD or the first STA or another STA in the non-AP MLD transmits the first frame. An AP MLD or a first AP or another AP in the AP MLD receives the first frame. The AP MLD or the first AP determines the padding duration of the initial control frame based on the indication information.

    Abstract: This application relates to the field of wireless communication, and in particular, to individually addressed traffic indication methods and apparatuses applicable to multiple links, for example, in a wireless local area network supporting an 802.11be standard. In an example method, a first access point (AP) of a first access point multi-link device (AP MLD) generates and sends individually addressed traffic indication information. The individually addressed traffic indication information is used to indicate whether a non-AP MLD associated with the first AP MLD has a downlink individually addressed traffic and whether a non-AP MLD associated with a second AP MLD has a downlink individually addressed traffic. The second AP MLD is an AP MLD to which a non-transmitted AP belongs. The non-transmitted AP is in a multiple basic service set identifier (BSSID) set in which the first AP is located.

    Abstract: This application discloses a multi-link device probing method and a communication apparatus, which may be applied to a wireless local area network supporting the 802.11 be standard. The method includes: A STA multi-link device generates a probe request frame, where the probe request frame carries first indication information used to indicate a first AP working on a first link in an AP multi-link device to feed back communication information of an AP that works on a second link and that is in the AP multi-link device, the communication information is used by the STA multi-link device to perform multi-link communication with the AP multi-link device, the second link is different from a first link; and the STA multi-link device sends the probe request frame on the first link.

    Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies. The method includes: An AP generates a trigger frame, where the trigger frame includes a first user information field, a part or all of a frequency domain resource indicated by a resource unit allocation subfield in a fourth user information field before the first user information field is located on a primary 160 MHz channel, and a part or all of a frequency domain resource indicated by a resource unit allocation subfield in a fourth user information field after the first user information field is located on a secondary 160 MHz channel. Then, the AP sends the trigger frame.

    Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STAMLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.
