    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: This disclosure relates to methods for transmitting and receiving multi-user request-to-send and clear-to-send frames in a wireless communication system. An access point wireless device may establish wireless connections with multiple wireless devices. The access point wireless device may transmit a multi-user request-to-send frame to the wireless devices. The multi-user request-to-send frame may indicate a transmit opportunity duration and allocate frequency resource units on which to transmit clear-to-send frames to the wireless devices. The wireless devices may transmit the clear-to-send frames on the allocated frequency resource units. The clear-to-send frames can include an indication of partial or full availability for the transmit opportunity.

    Abstract: An electronic device (such as an access point) is described. This electronic device transmits an orthogonal frequency division multiple access (OFDMA) frame to a recipient electronic device (such as a client or a station). The OFDMA frame includes multiple predefined resource units (RUs) allocated to the recipient electronic device in a set of predefined RUs having associated frequency bandwidths. Moreover, the multiple predefined RUs include two or more first predefined RUs having a first number of tones less than a predefined amount, or two or more second predefined RUs having a second number of tones greater than or equal to the predefined amount. For example, the predefined amount may include 242 tones. Note that the multiple predefined RUs may have the same or different numbers of tones. Moreover, the electronic may receive an acknowledgment or a block acknowledgment from the recipient electronic device.

    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: Disclosed herein are system, method, and computer program product embodiments for identity obscuration of a station (STA) connected to a wireless network to prevent the tracking of the STA. Embodiments include a STA configured to establish a security association with an access point (AP) based on an original long term identity for the station and an identity of the AP. The STA can transmit a new long term identity for the STA to the AP based on the security association. The STA can then transmit a request frame to change the original short term identity assigned to the STA to the AP. The STA can receive a response frame from the AP. The response frame can include a new short term identity assigned to the station by the AP. The STA can then map its new long term identity to its new short term identity assigned by the AP.
