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.

Abstract: For example, an Access Point (AP) may be configured to determine a plurality of beamformed sectors for communication with a plurality of wireless communication stations (STAs), wherein a beamformed sector for communication with a STA is based on a beamforming training between the AP and the STA; to determine a grouping sector for communication between the AP and a group of STAs including two or more grouped STAs of the plurality of STAs, wherein the grouping sector covers two or more beamformed sectors corresponding to the two or more grouped STAs; to listen over the grouping sector for a transmission from a grouped STA of the group of STAs; and, based on the transmission from the grouped STA, to communicate a beamformed transmission with the grouped STA via a beamformed sector corresponding to the grouped STA.

Abstract: This disclosure describes systems, methods, and devices related to multi-user uplink channel sounding. A device may determine a channel sounding sequence with one or more access points (APs), wherein the channel sounding sequence comprises a null data packet announcement (NDPA) communicated with at least one of the one or more APs. The device may determine a first group of station devices (STAs) associated with a first basic service set (BSS). The device may cause to send a trigger frame to the first group of STAs to solicit an uplink NDP from each STA of the first group of STAs. The device may identify a first uplink NDP received from a first STA of the first group of STAs. The device may identify a second uplink NDP received from a second STA of a second group of STAs.

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable for multi-band operation in a plurality of frequency bands, each frequency band comprising one or more channels. The AP may select a subset of the frequency bands for which the AP is to request per-band channel availability information from the STA. The AP may transmit a Trigger Frame (TF) for a multi-band bandwidth query report polling (MB-BQRP) to request the per-band channel availability information. The AP may receive an uplink frame that includes a multi-band bandwidth query report (MB-BQR) that indicates the per-band channel availability information. The AP may determine, based on the MB-BQR, for an uplink transmission by the STA: one or more frequency bands of the subset of frequency bands, and one or more corresponding channels.

Abstract: Methods, apparatuses, and computer readable media for a common preamble for wireless local-area networks (WLANs). An apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a portion of a physical layer (PHY) protocol data unit (PPDU), the first portion of the PPDU including a physical universal signal field (U-SIG), the U-SIG comprising a version independent portion and a version dependent portion, the version independent portion including a version identifier field, the version identifier field indicating a standard version of the PPDU. The processing circuitry is further configured to refrain from decoding the version dependent portion when the standard version indicates a standard version of a later generation than a standard version of the AP or STA, and otherwise decode the version dependent portion in accordance with the standard version.

Abstract: The application relates to ultra-low latency data transmission in Wireless Local Area Networks (WLANs). An apparatus used in a non-Access Point Station (non-AP STA), includes processor circuitry configured to cause the non-AP STA to, when there is urgent data that must be transmitted in uplink without waiting for a scheduled slot: generate a Protocol Data Unit (PDU) from the urgent data; and transmit the PDU on a resource unit pre-assigned for urgent transmission, wherein the resource unit is multiplexed for uplink transmission from multiple non-AP STAs.
