    Abstract: Systems, methods, and devices for indicating a target wake time (TWT) service period (SP) termination may include a first device which receives, from a second device, an indication for terminating a TWT SP. The first device may determine a status of downlink traffic for transmission to the second device. The first device may transmit, to the second device, an SP termination notification according to the status of the downlink traffic and the indication. The first device may terminate the TWT SP according to the SP termination notification.

    Abstract: A device within an access point multi-link device (AP MLD) having a plurality of wireless links, may include one or more processors configured to generate a frame including a first subfield, the first subfield indicating whether there is an update on one or more basic service set (BSS) level parameters or one or more MLD level parameters different from the one or more BSS level parameters. The one or more processors may determine whether there is an update on the one or more MLD level parameters. Responsive to determining that there is an update on the one or more MLD level parameters, the one or more processors may set the first subfield to a first value. The one or more processors may wirelessly transmit, through a transmitter via a link of the plurality of wireless links corresponding to the device in a wireless local area network (WLAN), the frame.

    Abstract: A first wireless multi-link device (MLD) may include a transceiver configured to transmit a first frame to a first station (STA) of a second wireless MLD over a first link of a plurality of links after waiting for an amount of time during which the first STA switches from a listening mode over the first link to a frame exchange mode over the first link. The transceiver may determine whether the first STA is in a power save mode or an active mode, and can transmit, in response to determining that the first STA is in a power save mode, a second frame to a second STA of the second wireless MLD over a second link of the plurality of links without waiting for an amount of time during which the second STA switches from a listening mode over the second link to a frame exchange mode over the second link.

    Abstract: A device may generate a frame relating to a target wake time (TWT) schedule. In response to determining that the device cannot accept a request for a new membership of the TWT schedule, the device may set a subfield of the frame to a first value, indicating, to a receiver device receiving the frame, to avoid sending a request for a new membership of the TWT schedule. In response to determining that there is at least one wireless device having a membership of the TWT schedule, the device may set the subfield of the frame to a second value. In response to determining that there exists another TWT schedule set up for an overlapping basic service set (OBSS), the device may set the subfield of the frame to a fourth value. The device may wirelessly transmit the generated frame to the receiver device.

    Abstract: A first device within a multi-link device having a plurality of wireless links including a first link and a second link, may include one or more processors configured to receive a first frame on the first link while communicating with a second device for transmission of a second frame on the second link. The one or more processors may decode a portion of the first frame to determine a first duration of no medium access. The one or more processors may determine, a second duration comprising a remaining transmission duration on the second link. The one or more processors may determine whether the first duration is greater than or equal to the second duration. In response to the first duration being greater than or equal to the second duration, the one or more processors may defer channel access on the first link until an end of the first duration.

    Abstract: Systems, methods, and devices for managing target wake time (TWT) schedules may include a first device of a wireless local area network (WLAN) which receives information relating to drift of a start time of a target wake time (TWT) schedule from a second device of the WLAN. The first device may modify a start time for a subsequent TWT service period, according to the information relating to the drift of the start time from the second device.
