Publication number: 20240137154Abstract: A station (STA) configured for operation in a WLAN may perform bit scrambling on input bits to generate scrambled input bits and may perform probabilistic constellation shaping using a shaping encoder on the scrambled input bits. The shaping encoder may encode a segment of the scrambled input bits for a modulation order and generate a shaped bit stream. In these embodiments, the STA may generate a QAM symbol stream with a QAM modulator. The QAM symbol stream may be generated at least from the shaped bit stream and from parity bits using the modulation order. The STA may generate the parity bits from the shaped bit streams with a forward-error correction (FEC) encoder and may transmit the QAM symbol stream within a physical layer protocol data unit (PPDU). To address a potential byte boundary shift caused a decoding error at a receiving station, the STA may modify performance of the bit scrambling when probabilistic constellation shaping is performed.Type: ApplicationFiled: December 29, 2023Publication date: April 25, 2024Inventors: Qinghua Li, Hao Song, Danny Alexander, Shlomi Vituri, Assaf Gurevitz, Robert J.

Patent number: 11864027Abstract: An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate, The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.Type: GrantFiled: April 16, 2021Date of Patent: January 2, 2024Assignee: Intel CorporationInventors: Po-Kai Huang, Daniel F.

Patent number: 11805561Abstract: Multi-link device (MLD) devices and transitions are described. The MAC addresses of the AP MLD and non-AP MLD are used to generate keys for different fast transitions (FT) between a non-AP MLD and an AP MLD. In an FT initial mobility domain operation, the AP MLD MAC address is used as the R1KH-ID and the non-AP MLD MAC address is used as the S0KH-ID and S1KH-ID. The MAC addresses are exchanged in Authentication Request/Response or Association Request/Response messages and the GTK/IGTK/BIGTK are delivered in a single FT 4-way handshake. In a fast MLD transition to an AP MLD in the same ESS, the other AP MLD MAC address is used as the R1KH-ID and the non-AP MLD MAC address is used as the S1KH-ID. The MAC addresses are exchanged in Authentication Request/Response or Association Request/Response messages and the GTK/IGTK/BIGTK are delivered in an FTE.Type: GrantFiled: December 23, 2020Date of Patent: October 31, 2023Assignee: Intel CorporationInventors: Po-Kai Huang, Ido Ouzieli, Robert J.

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
