  • 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.

  • Patent number: 11996317
    Abstract: A method includes etching a semiconductor substrate to form a trench and a semiconductor strip. A sidewall of the semiconductor strip is exposed to the trench. The method further includes depositing a silicon-containing layer extending into the trench, wherein the silicon-containing layer extends on the sidewall of the semiconductor strip, filling the trench with a dielectric material, wherein the dielectric material is on a sidewall of the silicon-containing layer, and oxidizing the silicon-containing layer to form a liner. The liner comprises oxidized silicon. The liner and the dielectric material form parts of an isolation region. The isolation region is recessed, so that a portion of the semiconductor strip protrudes higher than a top surface of the isolation region and forms a semiconductor fin.

  • Publication number: 20240137971
    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.
