US 2023/0413017 A1 · GROUP ADDRESSED TRAFFIC TRANSMISSION METHOD APPLICABLE TO PLURALITY OF LINKS AND APPARATUS

Abstract

This application is applicable to a group addressed traffic transmission method applicable to a plurality of links and an apparatus. In the method, group addressed traffic indication information is used to indicate whether each AP or an AP other than a first AP in an AP MLD has group addressed traffic; or group addressed traffic indication information is used to indicate whether each AP or an AP other than a first AP in an AP MLD and each AP or an AP other than a non-transmitted AP in an AP MLD in which the non-transmitted AP in a multiple BSSID set in which the first AP is located have group addressed traffic. This application is applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, an 802.11 series protocol such as 802.11be.

Claims23

Dependent claims

A group addressed traffic transmission method applicable to a plurality of links, wherein the method comprises:

receiving through a first link, from a first access point (AP) in a first access point multi-link device (AP MLD), group addressed traffic indication information, wherein:
the group addressed traffic indication information indicates whether a plurality of access points (APs) in the first AP MLD and a second AP MLD have group addressed traffic;
and
the first AP is in a multiple basic service set identifier (BSSID) set that includes a non-transmitted AP belonging to the second AP MLD;
and
determining, based on the group addressed traffic indication information, whether an AP of the first AP MLD and the second AP MLD has group addressed traffic.

3 more elements

A non-AP station multi-link device (non-AP STA MLD), the non-AP STA MLD comprises one or more station (STA), the STA comprises a transceiver and a processor, wherein the STA is configured to perform the following steps:

receiving through a first link, from a first access point (AP) in a first access point multi-link device (AP MLD), group addressed traffic indication information, wherein:
the generate group addressed traffic indication information, wherein:
the group addressed traffic indication information indicates whether a plurality of APs in the first AP MLD and a second AP MLD have group addressed traffic;
and
the first AP is in a multiple basic service set identifier (BSSID) set that includes a non-transmitted AP belonging to the second AP MLD;
and
determining, based on the group addressed traffic indication information, whether an AP of the first AP MLD and the second AP MLD has group addressed traffic.

4 more elements

A chip system, applied to a station (STA) in a non-AP station multi-link device (non-AP STA MLD), the STA comprises a transceiver and a processor, wherein the chip system comprises at least one processor and an interface, wherein the chip system is configured to perform the following steps:

receiving through a first link, from a first access point (AP) in a first access point multi-link device (AP MLD), group addressed traffic indication information, wherein:
the group addressed traffic indication information indicates whether a plurality of APs in the first AP MLD and a second AP MLD have group addressed traffic;
and
the first AP is in a multiple basic service set identifier (BSSID) set that includes a non-transmitted AP belonging to the second AP MLD;
and
determining, based on the group addressed traffic indication information, whether an AP of the first AP MLD and the second AP MLD has group addressed traffic.
