    摘要: This disclosure describes systems, methods, and devices related to aligned channel access. A device may perform a first backoff countdown on a first link associated with a first station device (STA) of the device, wherein the device is a multi-link device (MLD). The device may detect a second backoff countdown associated with a second STA of the MLD after the first backoff countdown reaches zero. The device may determine to hold the first backoff countdown at zero based on the value of the second backoff countdown. The device may transmit in synchronization on the first link and on the second link from the first STA and the second STA respectively based on holding the first backoff countdown at zero.

    摘要: Embodiments of an access point (AP) configured for extremely high throughput (EHT) operation may be configured to operate as a triggering AP for a trigger-based (TB) peer-to-peer (P2P) communication between a triggered direct (TD) station (STA) and a TD peer STA. The AP may encode a Direct Link Announcement (DiL-A) frame to schedule the TD STA for a direct link transmission to the TD peer STA. The DiL-A frame may be encoded to include a Duration/ID field. The AP may set the Duration/ID field of the DiL-A frame to a remaining duration of a transmission opportunity (TXOP) when the TD peer STA is an EHT STA that supports TB P2P operation (e.g., to allow the TD peer STA to ignore the NAV set by the DiL-A frame). The AP may set the Duration/ID field of the DiL-A frame to a response time for the TD STA to respond to the DiL-A frame when the TD Peer STA is a legacy STA (e.g., to allow the TD peer STA to set its NAV based on the response time).

    摘要: Slurry compositions and chemically activated CMP methods for polishing a substrate having a silicon carbide surface using such slurries. In such methods, the silicon carbide surface is contacted with a CMP slurry composition that comprises i) a liquid carrier and ii) a plurality of particles having at least a soft surface portion, wherein the soft surface portion includes a transition metal compound that provides a Mohs hardness ≦6, and optionally iii) an oxidizing agent. The oxidizing agent can include a transition metal. The slurry is moved relative to the silicon carbide comprising surface, wherein at least a portion of the silicon carbide surface is removed.

    摘要: This disclosure describes systems, methods, and devices related to multi-link acknowledgments. A device may transmit a trigger frame to a station device (STA) multi-link device (MLD), wherein the trigger frame polls the STA MLD to announce presence on communication links. The device may identify a null data packet (NDP) from the STA MLD announcing its presence on a set of communication links. The device may establish the set of communication links with the STA MLD, wherein the STA MLD comprises a plurality of station devices (STAs). The device may allocate a plurality of tone-sets to the plurality of STAs within the STA MLD. The device may identify energy on the allocated tone-sets for each link that the STA MLD has presence on.

    摘要: Apparatuses, computer readable media, and methods for multicast negative acknowledgements using high-energy long-training fields for feedback are disclosed. An apparatus of a wireless device is disclosed. The apparatus includes memory and processing circuitry coupled to the memory where the processing circuitry configured to: encode one or more packets in accordance with multicast or broadcast, cause to be transmitted the one or more packets to one or more stations, and decode feedback from the one or more stations. The feedback may be received simultaneously on a same resource block for each packet of the one or more packets. Each packet may be represented by one resource block of the one or more resource blocks. The resource blocks may be thirty-six resource blocks per 20 MHz subchannel with nine resource blocks in a frequency domain by four spatial streams.
