    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 described herein relate to a system and method for providing flexible receiver configuration in wireless communication systems, such as 802.11 WLAN systems. In one embodiment, a wireless device may transmit a first data frame including first configuration information specifying a first configuration of the receiver to notify a remote device that the wireless device intends to configure its receiver according to the first configuration. After receiving an acknowledgement frame confirming the first configuration information, the wireless device may configure the receiver according to the first configuration. In another embodiment, a wireless device may receive a first data frame including first configuration information and further including a request that the wireless device configure its receiver according to the first configuration. In response, the wireless device may configure the receiver according to the first configuration. In either case, the wireless device may receive subsequent communications according to the first configuration.

    Abstract: This disclosure relates to techniques for access control operation between devices in a wireless communication system. An access device may store reader group identifier information for one or more reader devices. The access device may receive an advertisement indication from a reader device in a wireless manner. The advertisement indication may include a reader group identifier for the reader device. The access device may determine that the reader group identifier information stored by the access device includes the reader group identifier indicated by the reader device. The access device may attempt to perform access control communication exchange with the reader device based at least in part on determining that the reader group identifier information stored by the access device includes the reader group identifier indicated by the reader device.

    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: An interface circuit in an electronic device (such as an access point) may receive a setup request associated with the recipient electronic device. The setup request may specify a group address for which the recipient electronic device wants to receive associated frames and a proposed transmission interval. Based at least in part on the proposed transmission interval, the electronic device may determine a transmission schedule and/or may assign, based at least in part on the group address, the recipient electronic device to an aggregated group having a flexible multicast service identifier (FMSID). Then, the electronic device may provide a wake-up frame for the recipient electronic device, where the wake-up frame includes an identifier of the aggregated group for which a group-addressed frame will subsequently be transmitted by the electronic device. Moreover, the wake-up frame may be provided at a transmission time based at least in part on the transmission schedule.

    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.
