    Abstract: A non-access point multi-link device (non-AP MLD) in a wireless network, the non-AP MLD comprising a memory and a processor coupled to the memory, the processor is configured to establish a target-wake time (TWT) agreement or a TWT schedule on a first link between the non-AP MLD and an AP MLD, transmit a first frame to the AP MLD to reconfigure one or more links between the non-AP MLD and the AP MLD, wherein the first frame requests that the first link be deleted or disabled, receive a second frame from the AP MLD that indicates acceptance of the request to delete or disable the first link, and modify the TWT agreement or the TWT schedule on the first link.

    Abstract: A non-access point multi-link device (non-AP MLD) in a wireless network, the non-AP MLD comprising a memory and a processor coupled to the memory, the processor configured to establish a first link between a first station (STA) affiliated with the non-AP MLD and a first AP affiliated with an AP MLD, establish a second link between a second STA affiliated with the non-AP MLD and a second AP affiliated with the AP MLD, establish a target-wake-time (TWT) agreement or a TWT schedule on the first link between the first STA and the first AP, and transmit, from the first STA to the first AP on the first link, a frame intended for the second AP operating on the second link, wherein the frame includes information regarding when the TWT agreement or the TWT schedule established on the second link is suspended.

    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: 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.
