摘要： Methods, apparatuses, and computer readable media for trigger frames or transmission opportunities with delayed uplink start are disclosed. Apparatuses of a station (STA) are disclosed, where the apparatuses comprise processing circuitry configured to decode a trigger frame, the trigger frame indicating that delayed transmission is permitted, indicating a length of a simultaneous uplink (UL) transmission, and indicating a resource unit (RU) for the uplink transmission to an access point (AP), encode a delayed UL trigger-based (TB) physical (PHY) protocol data unit (PPDU), and configure the STA to transmit the delayed UL TB PPDU on the RU after receiving the trigger frame, where data of the UL TB PPDU is delayed. from being transmitted during the simultaneous UI transmission,

摘要： Embodiments disclosed herein are directed to communicating time-critical ultra-low latency (ULL) data using one or more dedicated resource units (RUs). A station (STA) decodes a trigger frame received from an access point station (AP) encoded to indicate resource units (RUs) of an UL PPDU for an uplink multi-user orthogonal frequency division multiple access (UL MU OFDMA) data transmission by a first and a second station STA. The trigger frame may also be encoded to indicate configuration information for a dedicated RU for time-critical ultra-low latency (ULL) UL data. The dedicated RU may be one RU of one or more RUs of the UL PPDU that are reserved for time-critical communications. The STA may encode time-critical ULL UL data for transmission to the AP on the dedicated RU during the uplink MU OFDMA data transmission by the first and second STAs. The time-critical ULL UL data may start at any time during transmission of the UL PPDU. Medium access control layer (MAC) padding may be included in a MAC payload until the time-critical ULL UL data is available at the MAC layer of the STA.

摘要： A Quality-of-Service (QoS) Management AP is configured to support QoS Management features and to perform a QoS Management Protocol. The AP decodes an Enhanced Add Traffic Stream (E-ADDTS) Request QoS Action Frame (E-ADDTS Req) received from a station (STA) to initiate QoS setup for a traffic stream. The STA may be a QoS Management STA configured to support the QoS Management features and perform the QoS Management protocol. The AP may encode, for transmission to the STA in response to the E-ADDTS Req, an E-ADDTS Response QoS Action Frame (E-ADDTS Resp) which includes a status code to indicate whether the QoS setup has been accepted. When the QoS setup is accepted, the E-ADDTS Resp includes a QoS setup ID within a QoS setup ID field in the E-ADDTS Resp that uniquely identifies the QoS setup for the traffic stream.

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.

摘要： An access point station (AP) communicates with a plurality of non-AP stations (STAs) within a synchronized transmission opportunity (S-TXOP). The S-TXOP may comprise an S-TXOP trigger followed by a plurality of S-TXOP slots. After transmission of the S-TXOP trigger, the AP may encode, for transmission within an S-TXOP slot, a downlink (DL) multi-user physical layer protocol data unit (DL MU-PPDU). The DL MU-PPDU may include a preamble followed by a data field. To indicate that a previously signaled resource unit (RU) allocation is to be used during the S-TXOP slot, the AP may encode the preamble to include an allocation ID of the previously signaled RU allocation in a signal field (SIG) of the preamble and to include a SIG-2 presence indicator to indicate that a second signal field (SIG-2) is not included in the preamble.

摘要： This disclosure describes systems, methods, and devices related to fast transition Wi-Fi roaming operations. A device may generate, during a first association of the device to a first access point, a request to authenticate the device to a second access point; send, during the first association, the request to authenticate; receive, during the first association, a response indicating that the device is authenticated to the second access point; generate, during the first association, a reassociation request to the second access point; determine that a time between sending the request to authenticate and generating the reassociation request is less than a threshold time; send, based on the determination that the time is less than the threshold time, the reassociation request to the second access point; and receive a reassociation response indicative of a second association of the device to the second access point.

摘要： A multi-link access point (AP) device is configured for multi-link operation to communicate with a plurality of non-AP stations (STAs) over a plurality of corresponding links. A multi-link policy element is encoded for transmission to the non-AP STAs to signal a multi-link policy. The multi-link policy element comprises a common policy sub-element and a plurality of link-specific policy sub-elements. The common policy sub-element is applicable to all links. Each of the link-specific policy sub-elements is applicable to a single link. The link-specific policy sub-elements comprise at least a first link-specific policy sub-element applicable to a first link and a second link-specific policy sub-element applicable to a second link. The common policy sub-element defines a link policy for all links that have been set up between the multi-link AP device and the non-AP STAs. Each link-specific policy element defines a link policy specific to an associated link.
