Publication number: 20230379749Abstract: A non-Access Point Extremely High Throughput Station (non-AP EHT STA) initiates a Quality-of-Service (QoS) setup by sending a Stream Classification Service (SCS) Request frame to an associated access point (AP). The SCS request frame may be encoded to have a request type field set to “Add” and may contain an SCS Descriptor element having a traffic description field, a traffic classification field, and a Multi-Link Operation (MLO) field. The non-AP EHT STA may decode an SCS Response frame from the AP that indicate whether the QoS setup has been added. The non-AP EHT STA may then exchange a QoS traffic flow with the associated AP in accordance with the QoS setup when the QoS setup has been added. When the QoS traffic flow ends, the non-AP EHT STA may encode a second SCS Request frame for transmission to the AP with the request type field set to “Remove” to delete the QoS setup.Type: ApplicationFiled: December 8, 2021Publication date: November 23, 2023Inventors: Necati Canpolat, Dibakar Das, Ganesh Venkatesan, Dave A.

Patent number: 11792170Abstract: 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.Type: GrantFiled: May 16, 2022Date of Patent: October 17, 2023Assignee: Intel CorporationInventors: Qinghua Li, Jonathan Segev, Benny Abramovsky, Danny Alexander, Xiaogang Chen, Chittabrata Ghosh, Feng Jiang, Ido Ouzieli, Robert Stacey

Patent number: 11696225Abstract: 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.

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.Type: GrantFiled: May 23, 2022Date of Patent: July 4, 2023Assignee: Intel CorporationInventors: Dave A.
