AI Technical Summary
Technical Problem
The power consumption of station multilink devices is increased due to the need for periodic listening to determine the presence of downlink group addressable traffic in each access point, which is inefficient and wasteful.
Method used
A group addressable traffic transmission method that uses group addressing traffic instruction information to indicate whether one or more access points have group addressable traffic, reducing the need for stations to periodically listen, thereby conserving power.
Benefits of technology
This method reduces power consumption in station multilink devices by allowing stations to efficiently determine the presence of group addressable traffic without continuous listening, enhancing power efficiency.

Abstract
This invention provides a group addressing traffic transmission method and apparatus applicable to multiple links in a wireless local area network system that supports the IEEE 802.11ax next-generation Wi-Fi EHT protocol. [Solution] Group addressing traffic instruction information is used to indicate whether each AP in an access point multilink device (AP MLD) or APs other than the first AP have group addressing traffic, or the group addressing traffic instruction information is used to indicate whether each AP in an AP MLD or APs other than the first AP and each AP in an AP MLD of a non-transmitting AP in the multibasic service set identifier (BSSID) set where the first AP is located, or APs other than non-transmitting APs, have group addressing traffic.
