    Abstract: Embodiments are disclosed for triggered multi-link (ML) access coordination. A station (STA) ML device (MLD) can establish a preferred triggering link (PTL) with an access point (AP) MLD where the PTL is the preferred link for receiving triggering frames. The STA MLD can transmit uplink (UL) frames via the PTL in response to a trigger frame. Subsequently, the STA MLD can determine that the PTL is busy, and transmit enhanced distributed channel access (EDCA) UL frames on a non-PTL link. In a power save mode, the STA MLD can use the PTL to exchange UL and downlink (DL) frames. Multiple PTLs can be established supporting concurrent trigger frames, and different ranges of traffic IDs (TIDs) can be used for each PTL. The STA MLD can utilize AP MLD link pair information to receive a DL retransmission corresponding to one TID via both links of the AP MLD link pair.

    Abstract: Some aspects of this disclosure include apparatuses and methods for implementing a hibernation mode for multi-link wireless communication networks such as a wireless local area network (WLAN). For example, some aspects relate to a multi-link device (MLD) including a first station (STA) associated with a first link of a wireless network and configured to communicate with a second MLD over the first link. The MLD also includes a second STA associated with a second link of the wireless network. The second STA is in a hibernation mode. The MLD also includes one or more processors communicatively coupled to the first and second STAs and configured to control operations of the first and second STAs.

    Abstract: Some aspects of this disclosure include apparatuses and methods for implementing backup link establishment and operation for multi-link wireless communication networks such as a wireless local area network (WLAN). Some aspects relate to an electronic device including a transceiver configured to communicate over a wireless network and a processor communicatively coupled to the transceiver. The processor receives a message including information associated with a backup link from a second electronic device. The processor further receives data associated with data traffic from the second electronic device on a primary link of the wireless network. In response to a quality of the primary link being below a threshold, the processor receives a notification frame from the second electronic device on the backup link and receives additional data associated with the data traffic from the second electronic device on the backup link or on an other link informed by the notification frame.

    Abstract: Some embodiments include an apparatus, method, and computer program product for Extremely High Throughput (EHT) medium reservation. Some embodiments include a first station configured to exchange EHT-Request to Send (RTS) and/or EHT-Clear to Send (CTS) capabilities with a second station, and determine CTS response mode (e.g., rules) for the first station based at least on the RTS and CTS capabilities of the first and the second stations. Some embodiments include transmitting RTS frames and receiving CTS frames in the presence of punctured channels, implementing a flexible channel reservation scheme, reserving punctured bandwidths, and receiving CTS frames even when a primary channel is busy. Some embodiments include an RTS or an CTS frame that includes an EHT bandwidth puncture (BnP) signaling address and/or a modified scrambler seed that enable channel reservations for an EHT bandwidth.

    Abstract: Some embodiments include utilizing a multilink media access control (MAC) address structure to support multilink devices (MLDs) that can operate concurrently in more than one link such as extremely high throughput (EHT) access points (APs) and EHT stations (STA), where the multilink MAC address structure is compatible with legacy devices. An EHT AP can utilize a multilink basic service set (BSS) identification (BSSID) MAC address to communicate with an EHT STA identified by a multilink MAC address. Values of the multilink BSSID and the multilink MAC address of the EHT STA are independent of which of the multiple links are used in the communication. In addition, to utilizing a multilink BSSID, the EHT AP can also support unique link-specific MAC addresses to concurrently support legacy and MLD stations. The EHT STA can also utilize unique link-specific MAC addresses that can be different than the EHT AP's link-specific MAC addresses.

    Abstract: Methods and apparatuses are disclosed for high-bandwidth stations in a WiFi environment. In embodiments, a bandwidth of communications supported by the access point is divided into multiple frequency segments. In an embodiment, bandwidths up to 320 MHz are supported, which can be subdivided into four frequency segments of 80 MHz each. Different stations park on different frequency segments, whereas the access point has its primary channel located on the first frequency segment. With this configuration, uplink and downlink channel access can be provided to the different stations using a primary channel hopping pattern, which is provided to the stations from the AP. This pattern provides time windows for each frequency segment, during which the stations in that segment are able to freely communicate. Several other aspects of the disclosure further support this configuration and other high-bandwidth configurations.

    Abstract: Some embodiments include an apparatus, method, and computer program product for dynamic window access point (AP) power save enhancements. Some embodiments include transmitting an availability window (AW) of an AP to stations (STAs) and dynamically modifying the AW. In some embodiments, a mobile device may perform soft AP functions and associate with the stations. The modifications can include truncating or extending the AW. Some embodiments include: a broadcast availability frame that informs STAs of the modified AW; an Availability Clear To Send (A-CTS) frame that allows the AP to inform associated STAs of the modified AW; and/or an uplink (UL) multi-user (MU)-Request to Send (RTS) Enabled feature, that allows an AP to be available while operating in a low power receive (LPR) state (e.g., low power mode) and transition to a full power state to receive data using a bandwidth greater than 20 MHz.

    Abstract: Embodiments are disclosed for one-to-many and many-to-many ranging using narrowband assisted (NBA)-multi-millisecond (MMS) ultra wideband (UWB) protocols. Some embodiments include an initiator device that communicates with many responder devices. For example, the initiator device can transmit a control/initialization poll message via NB signaling that identifies a ranging cycle, and transmit a first set of MMS segments corresponding to the control/initialization poll message. The initiator device can receive a plurality of report frames from two or more responder devices via NB signaling subsequent to transmitting the first set of MMS segments, and transmit within the ranging cycle, a ranging results report message based at least on the plurality of report frames via narrowband signaling.
