1. A multilink device (MLD) access point (AP), comprising:
one or more transceivers configured to transmit and receive extremely high throughput (EHT) wireless communications over multiple links; and
a processor, coupled to the one or more transceivers, configured to:
transmit, via a first transceiver of the one or more transceivers using a first link of the multiple links, a beacon comprising: i) a multilink basic service set (BSS) identification (BSSID), wherein the multilink BSSID identifies an MLD media access control (MAC) address of the MLD AP, and the multilink BSSID remains the same regardless of which link of the multiple links is used for the transmission; and ii) a first link-specific BSSID corresponding to the first link of the multiple links; and
receive from an MLD station (STA), via a transceiver of the one or more transceivers using one link of the multiple links, a first frame comprising a multilink MAC address that identifies the MLD STA, wherein the multilink MAC address remains the same regardless of which link of the multiple links is used for the reception of the first frame.
