Abstract: A basic service set (BSS) corresponding to an access point (AP) affiliated with an AP multi-link device (MLD) is terminated when the AP is removed. The link ID assigned to the AP is no longer assigned to that AP. A BSS corresponding to an AP affiliated with an AP MLD is not terminated when the link on which the AP is operating is disabled. The affiliated AP maintains the link ID assigned to the AP.

Abstract: Methods and apparatuses for facilitating notification of an impending TDLS transmission in a wireless local area network. The apparatuses include a non-access point (AP) multi-link device (MLD) comprising stations (STAs) and a processor. Each STA comprises a transceiver configured to transceive signals on multi-link operation (MLO) links with APs of an AP MLD and on tunneled direct link setup (TDLS) direct links between the STAs and peer STAs of a second non-AP MLD, and to transmit, to the AP MLD on one of the MLO links, a TDLS transmission notification message. The processor is configured to determine that a TDLS transmission is impending over one of the TDLS direct links from one of the STAs that forms a non-simultaneous transmit/receive (NSTR) link pair with another STA, and to generate the TDLS transmission notification message, which includes an indication that the TDLS transmission is impending.

Abstract: Embodiments of the present disclosure provide methods and apparatuses for facilitating restricted target wake time (TWT) operation in a wireless local area network. The apparatuses include a non-access point (AP) multi-link device (MLD) comprising a plurality of stations (STAs) and a processor. Each STA comprises a transceiver configured for broadcast TWT operation on multi-link operation (MLO) links with corresponding APs of an AP MLD. The processor is operably coupled to the transceivers, and configured to negotiate a broadcast TWT schedule over a first link between a first STA and a first AP of the AP MLD, apply the broadcast TWT schedule to the group of links, negotiate a restricted TWT schedule with the AP MLD over at least one link of the group of links, and establish the restricted TWT schedule on one or more links of the at least one link.

Abstract: Embodiments of the present disclosure provide methods and apparatuses for requesting traffic characteristics in a wireless network. The apparatuses include a wireless station (STA) device comprising a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to transmit and receive signals. The processor is configured to generate a traffic profile request element that comprises an indication of a request for an access point (AP) to provide, to the STA, traffic characteristics, as observed at the AP, of downlink (DL) traffic between the AP and the STA. The transceiver is further configured to transmit to the AP the traffic profile request element. The requested traffic characteristics are used to determine target wake time (TWT) parameters for a TWT operation between the AP and the STA.
