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.

Abstract: Methods, apparatuses, and computer readable media for report identification and power control for multi-device wireless sensing in a wireless network are disclosed. An apparatus of an access point (AP) is disclosed, where the apparatus comprises processing circuitry configured to encode for transmission to a station (STA) a frame comprising a configuration hold subfield, the hold subfield indicating whether the STA should maintain a transmit configuration unchanged during uplink (UL) sensing. The processing circuitry further configured to encode for transmission a trigger frame (TF) for sensing, the TF for sensing including an identification of the STA, an indication of a resource unit (RU) for the STA to use to transmit an uplink (UL) sensing packet, and TF type subfield, the a TF type subfield indicating the TF for sensing.

Abstract: Embodiments of a WLAN sensing frame exchange protocol are generally described herein. In some embodiments, a wireless communication device is configured to perform a WLAN sensing protocol within a basic service set (BSS) comprising one or more stations (STAs) (STA1 and STA2) including an access point station (AP STA). The WLAN sensing protocol comprises a discovery phase, a negotiation phase, a measurement phase, and a reporting phase. To perform the WLAN sensing protocol, the wireless communication device is configured to operate as either a sensing initiator or a sensing responder, and to operate as a sensing transmitter and/or a sensing receiver. Some 60 GHz embodiments relate to WLAN sensing in a PBSS or IBSS with DMG STAs.

Abstract: This disclosure describes systems, methods, and devices related to link switch parameters. A device may generate a frame to be sent to a second device on a first link. The device may generate announcement information associated with the frame to notify other STAs about a data transmission of the frame. The device may cause to send on the first link the frame to the second device. The device may cause to send the announcement information with the data transmission of the frame.

Abstract: For example, a wireless communication device may be configured to disable a per-antenna Cyclic Shift Diversity (CSD) insertion for a Long Training Field (LTF) of a Physical Layer (PHY) Protocol Data Unit (PPDU), for example, based on a determination that the PPDU is to be configured for a predefined type of channel-sounding-based measurement. For example, the per-antenna CSD insertion may include insertion of a CSD between a plurality of transmit chains of the wireless communication device. For example, the wireless communication device may be configured to transmit the LTF of the PPDU via the plurality of transmit chains with the per-antenna CSD insertion disabled.

Abstract: Systems, methods, and devices related to an EHT multi-AP group are described. The coordinated APs of the EHT group are synchronized to the coordinator AP using a periodic or non-periodic frame. Each coordinated AP then synchronizes STAs associated with the coordinated AP. In response to an MPDU, either triggered by a trigger frame from the coordinator AP or initiated by the STA, an ACK frame or NDP response is sent by each AP receiving the MPDU. The response to the MPDU is dependent on whether frame aggregation is used, as well as whether the trigger frame triggers transmission of MPDUs from multiple STAs.

Abstract: For example, an Enhanced Directional Multi-Gigabit (EDMG) initiator station (STA) of a Beam Refinement Protocol (BRP) Transmit (TX) Sector Sweep (SS) (TXSS) may be configured to, during an initiator BRP TXSS, transmit one or more initiator EDMG BRP-TX packets to an EDMG responder STA; during a responder BRP TXSS following the initiator BRP TXSS, to receive one or more responder EDMG BRP-TX packets from the EDMG responder STA; and to transmit to the EDMG responder STA a BRP frame including feedback based on measurements on the one or more responder EDMG BRP-TX packets.
