  • Patent number: 12185369
    Abstract: An apparatus (e.g., an access point (AP) establishes a plurality of links comprising a primary link and at least a secondary link. The apparatus transmits a management frame on the primary link to indicate a multi-link capability of the AP. The apparatus configures the secondary link for one or more non-AP stations (STAs), which are capable of operating on the primary link and the secondary link, with multi-link capability and operating parameters through an association procedure on the primary link.

  • Patent number: 12185286
    Abstract: Embodiments of the present invention provide a punctured preamble enabling wireless devices to efficiently use a channel (e.g., an 80 or 160 MHz channel) where a primary service is operating. A Wideband Channel Access Mechanism for 20 MHz/80 MHz operating STAs is provided so that a 20 MHz/80 MHz operating STA can dynamically move to a secondary channel to improve wireless performance of the STA. An AP coordinates the operating channel switch of the 20 MHz/80 MHz operating STA. An EHT cooperative multi-band operation can be applied to the preamble punctured PPDU0 for simultaneous multi-band operation.

  • Patent number: 12166711
    Abstract: Embodiments of the present invention provide duplication schemes for control frames to extend the range of LPI in the 6 GHz wireless band for EHT WLAN. Duplicate 20 MHz legacy preambles containing L-STF, L-LTF, L-SIG and RL-SIG, U-SIG and EHT-SIG fields may be used to transmit beacon and other control frames using duplicate PPDUs to extend transmission range thereof. Non-HT duplication can be performed to maintain backwards compatibility with legacy devices. HE duplication can include duplication of a 20 MHz HE SU PPDUs over 40 MHz, 80 MHz, 160 MHz or 320 MHz portions, for example. DCM+MCS0 or duplication over DCM+MCS0 may be applied to the payload, and a duplication indication is inserted in the U-SIG field or EHT-SIG field to indicate if the duplication is applied to the payload over DCM+MCS0.

  • Publication number: 20240406950
    Abstract: System and method of cooperative multi-band wireless STA communication that enables full duplex operations are disclosed herein. Frames are configured to carry band information and are selected to be transmitted simultaneously in multiple bands based on various constraints to avoid out-of-order delivery. For frames under a block ACK agreement, a transmit STA can specify the transmission bands for the frames in an ADDBA request frame. While a first band is transmitting a first frame under a block ACK agreement, the second band can be used to transmit a frame under the same block ACK agreement as, and from the same traffic flow with, the first frame. Otherwise, the second band can be used to transmit a frame with a different TID than the first frame.

  • Patent number: 12160778
    Abstract: Embodiments of the present invention provide methods and devices for performing admission control in a wireless network. Admission control can be used to set usage limits for wireless devices in the network. When admission control is enabled, a wireless station does not transmit frames if the current channel usage time is greater than a predefined time limit. The admission control parameters can be specific to an access category (AC), such as best effort (BE), voice (VO), video (VI), and background (BK). According to some implementations, the admission control is performed on a link-level. According to other implementations, the admission control is performed at a multi-link device (MLD) level.

  • Publication number: 20240259308
    Abstract: A network device to function as an Access Point (AP) in a Wireless Local Area Network (WLAN) is provided. The AP is configured to acknowledge a data frame transmitted by a station (STA) in an uplink multi-user physical layer protocol data unit (UL MU PPDU). The AP includes one or more memories, a physical layer (PHY) processor, and a media access controller (MAC) processor. Each processor is coupled to the one or more memories, and is configured to receive the UL MU PPDU, decode an acknowledge (ACK) policy field within a data field of the UL MU PPDU, and determine whether an acknowledgement (ACK) policy indicated in the data field signals an implicit block acknowledgement (BlockAck) request. Responsive to a determination that the ACK policy indication signals an implicit acknowledgement policy, the AP is configured to transmit an ACK or BlockAck frame to the STA in either a single user (SU) or a multi user (MU) manner.
