Abstract: For example, an Access Point (AP) may be configured to determine that a high-priority contention period is to be initiated during a particular contention period. For example, the AP may be configured to determine that the high-priority contention period is to be initiated during the particular contention period based on a reservation signal received from a station (STA) over a wireless medium during the particular contention period. For example, the AP may be configured to allow the AP to contend the wireless medium during the high-priority contention period according to a high-priority contention policy, for example, to obtain a Transmit Opportunity (TxOP) for transmission of downlink (DL) data to one or more STAs.

Abstract: Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).

Abstract: This disclosure describes systems, methods, and devices related to service set compression. A device may determine a wake-up frame comprising one or more fields, wherein the one or more fields indicate an action to be taken on a receiving device. The device may determine an identifier to be indicated in the wake-up frame. The device may determine a size of the identifier. The device may cause to compress the identifier forming a compressed output, wherein the identifier is compressed by applying a cyclic redundancy code (CRC) computation. The device may identify a portion of the compressed output. The device may cause to send the wake-up frame to a receiving device, wherein the wake-up frame comprises the portion of the compressed output based on the size of the identifier.

Abstract: Logic may define one or more wake-up preambles suitable for high data rates for a wake-up radio (WUR) packet. Logic may define wake-up preamble with different counts of symbols. Logic may generate a wake-up preamble as two microsecond pulses of orthogonal frequency-division multiplexing (OFDM) symbols in a four megahertz (MHz) bandwidth. Logic may generate and receive a high data rate (HDR) WUR preamble or a low data rate (LDR) WUR preamble. The HDR preamble may signal a data rate of 250 kilobits per second and the LDR preamble may signal a data rate of 62.5 kilobits per second. The HDR preamble bit count may be twice a bit count of the LDR preamble. The HDR preamble may be 32 bits. The duration of transmission of the HDR may be 64 microseconds and duration of transmission of the LDR may be 128 microseconds.

Abstract: Embodiments of a station (STA) and method of communication are generally described herein. The STA may be included in a first plurality of STAs affiliated with a first multi-link logical entity (MLLE). A plurality of links may be established between the first MLLE and a second MLLE, wherein the second MLLE may be affiliated with a second plurality of STAs. The STA may receive a first subset of a sequence of MAC protocol data units (MPDUs). A second subset of the sequence of MPDUs may be transmitted by another STA of the first plurality of STAs. The STA may transmit a block acknowledgement (BA) frame that includes: a number of BA bitmaps, configurable to values greater than or equal to one; and BA control information for each of the BA bitmaps.

Abstract: Embodiments of a Next Generation Vehicle-to-Everything (NGV) station (STA) and method of communication are generally described herein. The NGV STA may encode a physical layer convergence procedure (PLCP) protocol data unit (PPDU) for transmission in a dedicated short-range communication (DSRC) frequency band allocated for vehicular communication by NGV STAs and legacy STAs. In some cases, the NGV STA may encode the PPDU in accordance with an NGV enhanced physical (PHY) layer protocol, and includes usage of a mid-amble, space-time block coding (STBC), or low-density parity check (LDPC) coding. In other cases, the NGV STA may encode the PPDU in accordance with a legacy PHY layer protocol that is compatible with the legacy STAs, and excludes usage of the mid-amble, the STBC, and the LDCP coding.

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. In a null data packet (NDP) based ranging procedure between a responding STA and an initiating STA that is unassociated with the responding STA, the responding STA may: transmit a broadcast frame that indicates one or more ranging parameters; receive, from the initiating STA, an NDP announcement (NDPA) frame that indicates transmission of a first NDP from the initiating STA; detect the first NDP from the initiating STA; transmit a second NDP for transmission to the initiating STA; and transmit, to the initiating STA, a location measurement report (LMR) that indicates: a reception time of the first NDP at the responding STA, and a transmission time of the second NDP at the responding STA.
