    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: Methods and apparatuses for supporting target wake time operation for enhanced multi-link multi-radio operation. A method for wireless communication performed by a non-access point (AP) multi-link device (MLD) that comprises stations (STAs), the method comprising: forming a first enhanced multi-link multi-radio (EMLMR) link for an EMLMR mode of operation with a first AP of an AP MLD; forming a second EMLMR link for the EMLMR mode of operation with a second AP of the AP MLD; establishing a first restricted target wake time (r-TWT) schedule that has an r-TWT service period (SP) is established on the first EMLMR link; determining that the non-AP MLD is operating in the EMLMR mode of operation with the AP MLD; and determining, based on the r-TWT SP, scheduling for traffic on the first EMLMR link and the second EMLMR link.

    Abstract: A method includes obtaining range estimates and carrier phase estimates from each of multiple anchors. The method also includes, in response to determining that a trilateration technique is to be performed, (i) obtaining improved range estimates using the carrier phase estimates and (ii) determining a first location estimate of a target device using the trilateration technique and the improved range estimates. The method also includes, in response to determining that a triangulation technique is to be performed, (i) obtaining differential range estimates using the carrier phase estimates and (ii) determining a second location estimate of the target device using the triangulation technique and the differential range estimates. The method also includes combining the first location estimate and the second location estimate to determine an overall location estimate of the target device.

    Abstract: A method includes repeatedly sending, by a first device, sync beacons to a second device in a target network at a first frequency. The method also includes determining that the second device will use beacons received from an unrelated sync provider (USP) device for synchronization of a clock of the second device with the target network. The method further includes repeatedly sending the sync beacons to the second device at a second frequency that is less frequent than the first frequency. The second frequency is determined based on a maximum synchronization error tolerance of the target network.

    Abstract: An access point (AP) affiliated with a non-simultaneous transmit and receive (NSTR) mobile AP multi-link device (MLD) and operating on a primary link may advertise a broadcast target wake time (TWT) schedule for the other AP affiliated with the same NSTR mobile AP MLD and operating on a nonprimary link by including a TWT element comprising a corresponding broadcast TWT parameter set field in the STA profile field of the Per-STA profile subelement of the basic multi-link element corresponding to the AP operating on the nonprimary link carried in beacon frames and/or probe response frame that it transmits on the primary link.

    Abstract: Methods and apparatuses for enhancing a scan phase for efficient mobility handling. A method of wireless communication performed by a non-access point (AP) multi-link device (MLD) (non-AP MLD) that includes stations (STAs) comprises: forming a link with a corresponding AP of an AP MLD, wherein the AP MLD comprises a plurality of APs that form a logical AP MLD; initiating a scan phase procedure over the link between the non-AP MLD and the corresponding AP to request information about the APs that form the logical AP MLD; and receiving a response from the corresponding AP based on the scan phase procedure, the response including information related to roaming received by the corresponding AP from other APs of the logical AP MLD.
