    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: Embodiments are disclosed for station (STA) identifier opt-in. Some embodiments include a STA that can associate with an access point (AP) of a wireless network, where the STA is configured to opt-in to being identified by the AP. The STA can transmit a first message 2 (M2) of a 4-way handshake protocol during the association, where the first M2 includes a Device Identifier (ID) Key Data Encapsulation (KDE) that includes an Opt-in Control field, where a first value of the Opt-in Control field indicates the STA opts-in to being identified by the AP. The STA can receive a first message 3 (M3) of the 4-way handshake protocol including a Device ID KDE and an ID Blob, where the ID Blob corresponds to the STA. The STA can communicate with the AP, where the first value enables the AP to collect data about the STA during the communication.

    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: A basic bandwidth wireless local area network (WLAN) device or station (STA) is assigned to a secondary channel. The basic bandwidth STA may be a 20 MHz STA. On the secondary channel, the basic bandwidth STA operates in a wideband mode recovering received data transmitted from an access point (AP) as part of a high bandwidth physical layer protocol data unit (PPDU). The STA and the AP can be members of a basic service set (BSS). The high bandwidth PPDU may be, for example, a 40 MHz, 60 MHz, or 80 MHz PPDU. Once on the secondary channel, the STA relies on the AP to perform channel sensing and scheduling activities, thus reducing power consumption at the STA and increasing the efficiency of the BSS. Several signaling formats are provided for indicating the secondary channel that the STA is assigned to or requests to move to.

    Abstract: A wireless local area network station (STA) changes a receiver operating mode (ROM) and saves power by influencing when a ROM-conforming access point (AP) transmission takes place. The STA evaluates candidate delay regimes after a negotiation exchange with the STA. The STA then instructs the AP of a selected delay regime which the AP is permitted to use when transmitting data according to the changed ROM. The ROM can involve a change in the system bandwidth demodulated by the STA and/or the number of spatial streams demodulated by the STA. The delay regime can allow the AP to transmit with little or no delay based on the changed ROM, or the delay regime may require a fixed time delay before the AP transmits according to the changed ROM.

    Abstract: Disclosed herein are system, method, and computer program product embodiments for enabling a spatial reuse opportunity at a high efficiency (HE) station and a network allocation vector (NAV) reset capability at a legacy station using a Request to Send and/or Clear to Send (RTS and/or CTS) frame. For example, the method can include receiving a RTS frame with a redefined field that specifies spatial reuse information. The NAV can be set based on the RTS frame. The method can determine whether a second frame was received within a threshold time after a Short Interframe Space (SIFS). Finally, the method can reset the NAV based on whether the second frame was received within the threshold time.
