Individually addressed traffic indication method applicable to multiple links and related apparatus

A communications apparatus comprising:

• a transceiver;
• at least one processor;
• and
• at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor and causing the communications apparatus to:
• generate individually addressed traffic indication information, wherein the individually addressed traffic indication information indicates whether a first non-AP MLD associated with a first AP MLD has a downlink individually addressed traffic and whether a second non-AP MLD associated with a second AP MLD has a downlink individually addressed traffic, and the second AP MLD is an AP MLD to which a non-transmitted AP belongs, and the non-transmitted AP is in a multiple BSSID set in which a first AP is located;
• and
• send the individually addressed traffic indication information on a first link, wherein the first link is a working link of the first AP.

A first access point multi-link device (AP MLD), wherein the first AP MLD includes a first AP and a second AP, the first AP comprising:

• a transceiver;
• at least one processor;
• and
• at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor and causing the first AP to:
• generate individually addressed traffic indication information, wherein the individually addressed traffic indication information is used to indicates whether a first non-AP MLD associated with the first AP MLD has a downlink individually addressed traffic and whether a second non-AP MLD associated with a second AP MLD has a downlink individually addressed traffic, and the second AP MLD is an AP MLD to which a non-transmitted AP belongs, and the non-transmitted AP is in a multiple basic service set identifier (BSSID) set in which a first AP is located;
• and
• send the individually addressed traffic indication information on a first link, wherein the first link is a working link of the first AP.
