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 STA MLD 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.

Abstract: A method includes: generating, by an access point AP, a first frame, where the first frame includes P station information fields, each of the P station information fields corresponds to one resource unit RU allocated to a first station STA, P is a positive integer greater than 1, each station information field further includes end indication information, and the end indication information is used to indicate whether the station information field is the last station information field in the P station information fields. The AP may allocate P RUs to the first STA, and indicate the P RUs to the first STA through the P station information fields in the first frame. Therefore, a resource allocation manner of the AP can be more flexible, a frequency selective gain of an OFDMA system can be effectively improved, and a system capacity can be increased.

Abstract: This application provides communication methods, apparatuses, and computer-readable storage media. In an example, a value of a specific element of a first access point (AP) (or a second AP) is reused in a management frame, to indicate specific elements of a plurality of APs in a multiple basic service set identifier (BSSID) set to which the first AP (or the second AP) belongs. The management frame does not need to carry a plurality of same specific elements in the multiple BSSID set. The described techniques can be applied to, for example, a wireless local area network system supporting IEEE 802.11ax next-generation Wi-Fi protocols, for example, 802.11 series protocols such as the 802.11be or the EHT.

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 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, 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.
