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: This application provides a channel contention method and a related apparatus. The method includes: After data transmission on a first link is completed or a block acknowledgment corresponding to data is received on the first link, a first non-access point station of a first multi-link device performs clear channel assessment CCA detection on a second link in a first time period, where a start moment corresponding to the first time period is the same as a moment at which the data transmission on the first link is completed; and when the CCA detection on the second link fails, the first non-access point station performs channel contention on the second link based on a second time period.
