Abstract: This disclosure provides methods, devices and systems for establishing and maintaining connectivity between access points (APs) that provide multiple BSSID sets and wireless stations (STAs) that do not support enhanced multiple BSSID advertisement (EMA). In some implementations, a wireless communication device may transmit a burst of beacon frames each carrying a respective partial list of nontransmitted BSSID profiles for a multiple BSSID set. In such implementations, the bursts of beacon frames may be transmitted periodically such that the start of each burst occurs one beacon interval after the start of a prior burst. In some other implementations, a wireless communication device may broadcast multiple beacon frames each carrying a full set of nontransmitted BSSID profiles associated with a respective multiple BSSID set. In such implementations, each beacon frame may be periodically broadcast every beacon interval.

Abstract: This disclosure provides methods, devices and systems for reducing beacon bloat, inefficient spectrum use, and coupling of multi-link transmission element (MLTE) with a traffic indication map (TIM) element. In certain aspects, an MLTE may be transmitted by an access point (AP) multi-link device (MLD) in a frame separate from the beacon frame to reduce the size of the beacon frame. In such an example, the beacon frame may provide an indication to a non-AP MLD that is should remain awake to receive data. In certain aspects, the AP may transmit multiple MLTEs to reduce the amount of bandwidth used for MLTE transmission by cutting out non-AP MLDs and other stations (STAs) that do not have buffered data. In certain aspects, the AP may assign each non-AP MLD capable of transmission identifier (TID)-to-link mapping (TID2LM) with a per-link traffic indication bitmap (PLTIB) to decouple the MLTE from the TIM element.
