Access point AP multi-link device discovery method and related apparatus

An apparatus, comprising:

• at least one memory storing program instructions;
• and
• at least one processor coupled to the at least one memory, wherein the program instructions, when executed by the at least one processor, enable the apparatus to:
• generate a management frame, wherein the management frame comprises a first information field, wherein the first information field indicates a multi-link device (MLD) identifier of an access point multi-link device (AP MLD) with which a reported AP is affiliated or the first information field indicates that the reported AP is not affiliated with any AP MLD;
• and
• send the management frame to a station.

An apparatus, comprising:

• at least one memory storing program instructions;
• and
• at least one processor coupled to the at least one memory, wherein the program instructions, when executed by the at least one processor, enable the apparatus to:
• receive a management frame from a reporting access point (AP), wherein the management frame comprises a first information field, wherein the first information field indicates a multi-link device (MLD) identifier of an AP MLD with which a reported AP is affiliated or the first information field indicates that the reported AP is not affiliated with any AP MLD;
• and
• determine the MLD identifier of the AP MLD with which the reported AP is affiliated or that the reported AP is not affiliated with any AP MLD according to the first information field.
