  • Publication number: 20230180127
    Abstract: A device may generate a frame relating to a target wake time (TWT) schedule. In response to determining that the device cannot accept a request for a new membership of the TWT schedule, the device may set a subfield of the frame to a first value, indicating, to a receiver device receiving the frame, to avoid sending a request for a new membership of the TWT schedule. In response to determining that there is at least one wireless device having a membership of the TWT schedule, the device may set the subfield of the frame to a second value. In response to determining that there exists another TWT schedule set up for an overlapping basic service set (OBSS), the device may set the subfield of the frame to a fourth value. The device may wirelessly transmit the generated frame to the receiver device.

  • Patent number: 11665780
    Abstract: A multi-link access point (AP) device is configured for multi-link operation to communicate with a plurality of non-AP stations (STAs) over a plurality of corresponding links. A multi-link policy element is encoded for transmission to the non-AP STAs to signal a multi-link policy. The multi-link policy element comprises a common policy sub-element and a plurality of link-specific policy sub-elements. The common policy sub-element is applicable to all links. Each of the link-specific policy sub-elements is applicable to a single link. The link-specific policy sub-elements comprise at least a first link-specific policy sub-element applicable to a first link and a second link-specific policy sub-element applicable to a second link. The common policy sub-element defines a link policy for all links that have been set up between the multi-link AP device and the non-AP STAs.

  • Patent number: 11638202
    Abstract: An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.

  • Publication number: 20220407844
    Abstract: The disclosure provides some embodiments for securing long training field (LTF) sequence. A responding station (RSTA) configures a location management report (LMR) frame. The LMR frame is configured to include an LMR in respect of a previous measurement, and data to be used to generate a null data packet (NDP) for a current measurement that is to be performed following the previous measurement. The RSTA further encrypts the LMR frame using protected management frames (PMF) scheme, and transmits the encrypted LMR frame to an initiating station (ISTA) for generating an LTF sequence for the current measurement. In response to receiving an NDP announcement (NDPA) and an NDP for the current measurement from the ISTA, the RSTA generates an NDP for the current measurement based on the NDPA and the data using CCMP, and transmits the NDP to the ISTA.
