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: Disclosed herein are related to a wireless communication. In one aspect, a wireless communication device receives a frame including a first indication that indicates the wireless communication device to disable transmission during a quiet period. The quiet period may overlap with a restricted service period of a restricted target wake time (TWT) schedule of the wireless communication device. In one aspect, the wireless communication device may determine to ignore the first indication for the quiet period based on a defined rule or a separate indication indicating the wireless communication device to ignore the first indication.

Abstract: Disclosed herein are a system, a method and a device for switching between different communications protocols. A head wearable display can transmit, to a console during a first session interval, a first request to switch from a first link using a first communication protocol to a second link using a second communication protocol. The first request can include at least one characteristic of the first link. The head wearable display can receive, from the console, a first response to the first request, to perform a switch from the first link to the second link. The first response can indicate a wake up time and a second session interval to perform the switch. The head wearable display can switch from the first link to the second link in the second session interval and after the wake up time.

Abstract: Disclosed herein includes a system, a method, and a device for providing latency sensitive links. A wireless device can receive, from a wireless node, an advertisement message indicating a set of wireless local area network (WLAN) links that support one or more defined latency requirements, a capability of the wireless node to support the set of WLAN links, a plurality of parameters, an operating mode, and a status for the set of WLAN links. The wireless device can send, to the wireless node responsive to the advertisement message, a request to access a first link of the set of WLAN links. The request can indicate a capability of the wireless device to interoperate with the wireless node to use the first link. The wireless device can access the first link of the set of WLAN links if the wireless node accepts the request to access the first link.

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.
