Abstract: Methods, apparatuses, and computer readable media for an access point (AP), where an apparatus of an AP comprises processing circuitry configured to: decode a first defer signal frame, determine the first defer signal frame is from a station (STA) associated with the AP, and encode, for transmission, in a subsequent contention period a second defer signal frame. The processing is further configured to: determine the first defer signal is from the STA associated with the AP based on one of: a basic service set (BSS) subfield in a physical (PHY) portion of the first signal frame, a transmitter address in a media access control (MAC) portion of the first defer signal frame, a receiver address in the MAC portion of the first defer signal frame, or a service field of the first signal field.

Abstract: This disclosure describes systems, methods, and devices related to scheduling asynchronous transmissions by other access point (AP) devices in a multi-AP environment. A method may include a coordinating AP identifying a first time for a first coordinated AP device to send a first physical layer (PHY) protocol data unit (PPDU) using a first frequency segment; identifying a second time different than the first time for a second coordinated device to send a second PPDU using a second frequency segment; generating one or more frames comprising indications that the first AP device is to send the first PPDU using the first frequency segment and that the second AP device is to send the second PPUD using the second frequency segment; and causing to send the one or more frames to the first coordinated AP device and the second coordinated AP device.

Abstract: An apparatus may be configured to perform communication over a millimeterWave (mmWave) channel assisted by communication over a sub 10 Gigahertz (GHz) (sub-10 GHz) channel. For example, a wireless communication device may be configured to identify a link block event including a blocking of an mmWave wireless communication link between an mmWave wireless communication station (STA) of the wireless communication device and an other wireless communication device. For example, the wireless communication device may be configured to, based on the link block event, communicate with the other wireless communication device over a sub-10 GHz wireless communication link between a sub-10 GHz STA of the wireless communication device and the other wireless communication device.

Abstract: 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.

Abstract: This disclosure describes systems, methods, and devices related to enhanced retransmission. A device may establish one or more links with a station device (STA) multi-link device (MLD). The device may generate a frame to be sent to the STA MLD. The device may sense that a first link of the one or more links is busy. The device may cause to send the frame on a second link. The device may cause to send a duplicate of the frame on the first link at a first time.

Abstract: 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.

Abstract: 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).

An apparatus of a responding station (RSTA) is disclosed, where the apparatus comprises processing circuitry configured to perform ranging with a initiating stations (ISTAs) and maintain a separate sounding dialogue token for each of the ISTAs and transmit a corresponding sounding dialogue token for a ISTA in a trigger frame for ranging and sounding or a null data packet announcement (NDPA) frame, and in a responding to initiating location measurement report. Apparatuses of RSTAs and ISTAS are disclosed that perform power control management during non-trigger-based ranging.

Abstract: This disclosure describes systems, methods, and devices related to uplink (UL) null data packet (NDP) format for passive location. A device may cause to send a trigger frame that solicits poll response to one or more anchor stations involved in a passive ranging measurement. The device may identify one or more polling response frames received from the one or more anchor stations. The device may cause to send a trigger frame that solicits uplink null data packet (NDP) to the one or more anchor stations, wherein the uplink NDP comprises an indication of a high efficiency (HE) single user (SU) frame type. The device may identify one or more uplink NDPs received from the one or more anchor stations
