  • Publication number: 20240237054
    Abstract: An extremely high throughput (EHT) station (STA) configured for trigger based (TB) transmission may decode an trigger frame (TF) received from an access point (AP). The TF may include an assignment of resources comprising one or more 20 MHz channels. The EHT STA may determine which of the one or more assigned channels are available for transmission and which of the allocated channels are unavailable when the EHT STA is assigned more than one 20 MHz channel. The EHT STA may encode a EHT TB PPDU in response to the trigger frame. The EHT TB PPDU may be encoded to include an EHT preamble followed by a data field. The EHT preamble may be encoded to indicate channel availability. The EHT STA may generate signalling to cause the EHT STA to transmit the encoded EHT TB PPDU only on the assigned channels that have been determined to be available.

  • Patent number: 12022322
    Abstract: An extremely high-throughput (EHT) station (STA) may encode a null data packet (NDP) announcement frame for transmission to include a high-efficiency (HE) subfield and a Ranging subfield in a Sounding Dialogue Token field. To identify the NDP announcement frame as an EHT NDP announcement frame (i.e., an EHT variant), the EHT STA may set both the HE subfield and the Ranging subfield in the Sounding Dialogue Token field to a value of one. When operating as an EHT access point (AP), the EHT STA may encode a trigger frame to include a Special User Info Field. The Special User Info Field may be identified by a predetermined value as an STA association identifier (AID) value. The use of the predetermined value as the AID value in the Special User Info Field indicates that the trigger frame is an EHT variant and indicates that the trigger frame is being sent by an EHT AP.

  • Publication number: 20240204907
    Abstract: For example, an AP may be configured to set RU allocation information for a user STA in an RU allocation subfield of a user field for the user STA. For example, the RU allocation information for the user STA may indicate an RU allocation for a TB UL transmission from the user STA. For example, the AP may be configured to set a 7-bit UL MCS subfield, for example, after the RU allocation subfield, to indicate a first MCS and a second MCS for the user STA. For example, the first MCS may be assigned to a first UL resource of the RU allocation for the user STA, and the second MCS may be assigned to a second UL resource of the RU allocation for the user STA. For example, the AP may be configured to transmit a trigger frame including the user field for the user STA.

  • Patent number: 12010516
    Abstract: Multi-link device (MLD) security association (SA) query and query response procedures are described. Any of the links between an access point (AP) MLD and a non-AP MLD may be used to initiate association, reassociation, or disassociation procedures using the SA query requests and responses. The SA query request or response from one of the stations (STAs) associated with the MLD is sent to a corresponding linked one of the STAs associated with the other MLD. The SA request or response is addressed to the other MLD rather than the STA of the other MLD. Retry timeouts and maximum timeouts for resending SA query requests are set by the AP MLD and the same across each of the links.
