  • Publication number: 20250141599
    Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a first wireless device. The method generally includes generating a protected frame that indicates: 1) an updated starting sequence number (SSN) of a block acknowledgment (BA) window and 2) an intended purpose of the protected frame as a request to update a BA window with the updated SSN; outputting, for transmission to a second wireless device that the first wireless device has established a protected block acknowledgment (BA) agreement with, the protected frame; generating multiple medium access control (MAC) Protocol Data Units (MPDUs) with SNs within the updated BA window; and outputting, for transmission to the second wireless device, the multiple MPDUs.

  • Patent number: 12232059
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for analyzing management frames for multiple basic service sets (BSSs). In one aspect, a wireless node may obtain a first management frame from a wireless local area network (WLAN) apparatus, the WLAN apparatus operating multiple virtual access points (VAPs) respectively corresponding to multiple BSSs. The wireless node may determine whether the first management frame includes a BSS profile of a BSS associated with the wireless node based, at least in part, on an arrangement of a plurality of BSS profiles within one or more management frames. The wireless node may determine to further process the first management frame based, at least in part, on a determination that the first management frame includes the BSS profile of the BSS associated with the wireless node.

  • Patent number: 12167469
    Abstract: An access point (AP) may prioritize the allocation of uplink resources between multiple basic service sets (BSSs). In some aspects, the AP may select one of a plurality of BSSs, may allocate one or more random-access resource units (RUs) to only the selected BSS, and may transmit, for each of the selected BSSs, a respective frame indicating the random-access RUs allocated to that BSS. Wireless devices belonging to the selected BSS may contend for access to the random-access RUs allocated by the frame, and then transmit uplink data using the random-access RUs.

  • Publication number: 20240314567
    Abstract: This disclosure provides methods, components, devices and systems for performing actions to protect a wireless access point (AP) from repeated incorrect security credential input attacks. For example, a combination of techniques are implemented to block a wireless station (STA) from submitting innumerable number of incorrect security credential inputs to connect to the wireless AP by using embargo lists to block the wireless STA media access control (MAC) address after N number of consecutive unsuccessful attempts to connect to the wireless AP, using telescopic delays to make it progressively harder for the wireless STA to attack (that is, repeatedly submit incorrect security credential inputs) at regular short intervals, and/or determining position of the wireless STA of the attacker and then block attacks from all wireless STAs at the determined location.

  • Publication number: 20240298173
    Abstract: This disclosure provides methods, components, devices, and systems for securing frames. In some examples, a frame is transmitted with a field that includes an identifier (ID) of a security key, a packet number (PN), and an integrity check based on one or more portions of the control frame and the security key. A device receiving the frame can verify the frame by calculating another integrity check based on the frame and the identified security key and comparing the calculated integrity check to the received integrity check.

  • Publication number: 20240089791
    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may buffer uplink communications. However, such approaches may be improved. An access point (AP) may receive, from a station, uplink traffic of a traffic flow for forwarding to a backhaul network via a backhaul link. The AP may monitor a buffer of the AP to determine that a quantity of buffered uplink traffic received from the station exceeds a buffer quota, the buffer quota set for the traffic flow based on a traffic throughput capacity of the backhaul link and a throughput parameter for the traffic flow. The AP may modify, based on the quantity of buffered uplink traffic exceeding the buffer quota, an uplink communication scheme to reduce the quantity of uplink traffic from the station.

  • Publication number: 20230413208
    Abstract: This disclosure provides methods, devices and systems for performing a single-sided ranging operation. In some implementations, a first device transmits a first frame to a wireless station (STA), and receives a second frame from the STA responsive to the first frame. The first device obtains information indicating a time period between transmission of the first frame and reception of the second frame by the first device, and obtains information indicating time delays associated with a plurality of second devices, where each of the time delays is between respective receptions of the first frame and the second frame by a respective one of the second devices. The first device obtains a position of the STA based on the time period, the time delays associated with the plurality of second devices, and signal propagation times between the first device and each of the plurality of second devices.

  • Publication number: 20230362822
    Abstract: Aspects relate to signaling the parameters to be used for a communication schedule such as a target wake time (TWT) schedule. For example, a first wireless communication device (e.g., an access point or a peer station) may determine (e.g., specify or negotiate) the parameters for at least one TWT schedule and transmit a broadcast management frame (e.g., a beacon) that includes these parameters. A second wireless communication device (e.g., station) that receives the broadcast management frame may, based on the received parameters for one TWT schedule or the received parameters for multiple TWT schedules, elect to transmit during a transmission opportunity (TXOP) that is defined to not cross at least one boundary of a period of time indicated by the parameters.

  • Patent number: 11509419
    Abstract: This disclosure provides methods, devices and systems for acknowledgement and retransmission, and more specifically, to methods, devices and systems that enable a secondary wireless channel to provide acknowledgements of data transmitted on a primary wireless channel concurrently with the reception of additional data on the primary wireless channel. In some implementations, a transmitting device may transmit wireless packets including multiple codewords to a receiving device via a first wireless channel. The receiving device may attempt to decode the received codewords based on primary information in the codewords. The receiving device may then transmit to the transmitting device, via a second wireless channel, a codeword acknowledgement that identifies codewords that the receiving device did not successfully decode. The transmitting device may then transmit parity information to the receiving device via the first wireless channel that aids the receiving device in decoding the identified codewords.
