    Abstract: This disclosure provides methods, devices, and techniques to indicate operations by extremely high throughput (EHT) devices on an operating bandwidth, including devices in a basic service set (BSS) supporting the use of a 320 MHz channel. In some aspects, the supported functionality may include extensions to flexibility and support rules, structures, and signaling using legacy fields, frames, and features. In addition, the supported functionality may include channel sensing and reporting, such as per-channel network allocation vectors (NAVs) for the sub-channels of the operating bandwidth. A device may identify an operating mode for an operating bandwidth and determine a value for a bandwidth query report (BQR) or a target wake time (TWT) element. The device may check multiple NAVs for sub-channels of the operating bandwidth. The operating bandwidth may span concurrent operations on traditional Wi-Fi frequency bands including the 2.4 and 5 GHz bands as well as the 6 GHz band.

  • Publication number: 20230276466
    Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for providing uplink broadcast service connectivity via a wireless local area network (WLAN). In some implementations, a wireless device may transmit an uplink communication to an access point (AP) that supports uplink broadcast services, and the AP may forward the uplink communication to a remote destination indicated in the uplink communication. In some implementations, the wireless device may be in an unassociated state and may transmit the uplink communication without establishing a formal wireless session with the AP. The uplink communication may include a request for the AP to embed AP-provided data to the uplink communication before forwarding it the remote destination. This disclosure includes techniques to prevent flooding and unauthorized uplink communications being used for a denial of service attack on the remote destination.

  • Patent number: 11743709
    Abstract: A first access point (AP) of an AP multi-link device (MLD) is associated with a first communication link, and one or more secondary APs of the AP MLD are associated with one or more respective secondary communication links of the AP MLD. The first AP of the AP MLD generates a frame including a first change sequence field and one or more secondary change sequence fields. The first change sequence field indicates a presence or absence of a critical update associated with the first communication link, and each of the one or more secondary change sequence fields indicates a presence or absence of a critical update associated with a corresponding secondary communication link of the AP MLD. The first AP of the AP MLD transmits the frame over the first communication link of the AP MLD to a station (STA) of a STA MLD.

  • Patent number: 11737021
    Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication that can be used to establish a restricted target wake time (TWT) session on a wireless medium. In some implementations, an access point (AP) establishes a restricted TWT session for one or more wireless stations (STAs) associated with latency sensitive traffic, the restricted TWT session including restricted TWT service periods (SPs) during which the AP reserves access to the wireless medium for only the one or more STAs associated with the latency sensitive traffic. The AP transmits a clear-to-send (CTS) frame at a start of each restricted TWT SP, the CTS frame indicating to other STAs that the wireless medium is unavailable for a duration of the respective restricted TWT SP. The AP transmits latency sensitive data to or receives latency sensitive data from the one or more STAs during at least one of the restricted TWT SPs.

  • Publication number: 20230262763
    Abstract: In some implementations, a first access point (AP) selects one or more other APs for participation with the first AP in a coordinated access point transmission session. The first AP obtains a transmission opportunity (TXOP), and transmits a frame indicating scheduling information for uplink (UL) or downlink (DL) transmissions to or from the selected APs, the scheduling information indicating a respective start time for the UL or DL transmissions to or from the selected APs, at least two of the start times being offset from one another by a time period associated with decoding a preamble of a wireless packet. The first AP transmits or receives wireless packets to or from one or more associated stations (STAs) at least partially concurrently with the transmission or reception of wireless packets by the selected APs to or from their respective associated STAs based on the scheduling information.

  • Patent number: 11728924
    Abstract: This disclosure provides methods, devices and systems for enhanced bandwidth puncturing. Some implementations more specifically relate to punctured channel indications that support channel puncturing over a range of bandwidths achievable in accordance with the Institute of Electrical and Electronics Engineers (IEEE) 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an access point (AP) may communicate static punctured channel information to each associated wireless station (STA) in its BSS. In some other implementations, a transmit opportunity (TXOP) holder may communicate dynamic punctured channel information to a TXOP responder with which it intends to communicate. Still further, in some implementations, the TXOP responder may communicate additional punctured channel information to the TXOP holder responsive to the dynamic punctured channel information.

  • Patent number: 11729670
    Abstract: Certain aspects of the present disclosure provide techniques that may allow a device participating in a setup procedure to efficiently propose a range of values for a negotiated parameter. The techniques may reduce setup time, for example, allowing a responder to accept a value within the proposed range which may eliminate overhead associated with some of the back and forth message exchange of typical negotiations.

  • Patent number: 11722946
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify an aggregation capability to communicate in parallel over a plurality of wireless links. The wireless device may in some cases broadcast this aggregation capability (e.g., periodically). Additionally or alternatively, the wireless device may transmit the aggregation capability in response to a request received from another wireless device. In some cases, the first wireless device may transmit a request to a second wireless device inquiring about aggregation capabilities of the second wireless device. The second wireless device may respond with its aggregation capabilities (e.g., or may broadcast its aggregation capabilities independently of receiving the response). The wireless devices may establish a multi-link session based at least in part on the indicated aggregation capabilities.
