Abstract: A station may use information from a reduced neighbor report to determine which neighboring access points (APs) to scan. A station may receive the reduced neighbor report from an AP. The reduced neighbor report may include one or more parameters related to security, verification status, or capabilities of neighbor APs. The station may scan channels of the one or more of the neighbor APs based on the security, the verification status, or the capabilities of the neighbor APs.

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: Disclosed are methods, systems, and computer-readable medium to perform operations including detecting a reception opportunity of a physical layer protocol data unit (PPDU) scheduled to be transmitted by a transmitter, where the PPDU includes a preamble and one or more media access control (MAC) PDUs (MPDUs); decoding the preamble of the PPDU; detecting that reception of the one or more MPDUs has failed; and in response to the detecting, preparing a Negative Acknowledgment (NACK) message for transmission to the transmitter.

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: This disclosure relates to methods for transmission preemption in a wireless local area network. An access point wireless device may establish a wireless association with another wireless device. A first data transmission may be initiated. The transmitting wireless device may determine to preempt the first data transmission prior to its completion. The transmitting wireless device may transmit signaling indicating that the first data transmission is preempted.

Abstract: Multiuser (MU) Multi-TID (multi-traffic-identifier) transmission may be enabled in a resource unit (RU). To transmit an urgent payload as soon as possible, the urgent payload may be injected/included into the ongoing MU physical protocol data unit (MU PPDU), if possible. This may be accomplished by indicating to the latency-sensitive wireless station (STA) the ID of a companion (or buddy) station that has an assigned resource unit (RU) on which the STA may expect to receive the urgent payload, also referred to as the “overloaded RU.” Alternatively, an extra user field in the preamble of the MU PPDU may be used to indicate to the STA its station ID as well as the location of the overloaded RU. A receiver operating on an A-MPDU may select the RU it receives, and may identify (or determine) a wrong transmission based on the transmitter address.

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: A wireless device may coordinate UWB channel usage with neighboring devices. In some embodiments, an initiator may periodically send an ultra-wideband acquisition packets (UWB-AP). The UWB-AP may comprise information of future UWB channel usage of the initiator. Neighboring UWB devices may receive the UWB-AP and adjust channel usage based on the UWB-AP.
