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: 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. The S-TXOP slots may be configured for communication of synchronous data. For communication of small time-critical (TC) packets within the S-TXOP with one or more of the STAs, the AP may configure the S-TXOP for asynchronous ultra-low latency (ULL) transmissions by providing a low-latency channel access opportunity within the S-TXOP.

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: 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: This disclosure describes systems, methods, and devices related to channel estimation for coordinated access point (AP) transmissions. A device may identify of one or more access points associated with a coordinated basic service set. The device may determine to transmit one or more packets to a station device in coordination with the one or more access points. The device may determine one or more first training fields associated with one or more antennas of the device. The device may cause to send the one or more first training fields to the station device on one or more first communication links between the device and the station device.

Abstract: Methodologies are presented that provide better uplink and downlink data throughput for cell-edge stations (CE STAs) in wireless networks. In downlink, two or more access points (AP) can work in concert to code a signal such that each AP sends a portion of the data during concurrent transmissions. To further enhance the data throughput of a CE STA, each link between the CE STA and one of the APs can have different characteristics or parameters, for example, a different modulation and coding scheme (MCS). The different characteristics or parameters are communicated to the CE STA through one of various signals sent to the CE STA to allow the CE STA to receive the portions of data over the differently configured links.

Abstract: A wireless communication device, system and method. The device includes a memory and processing circuitry coupled to the memory. The processing circuitry has a main baseband processor and a low power baseband processor, and further includes logic to cause the low-power baseband processor to process an orthogonal frequency division multiple access (OFDMA) signal allocated to a predetermined resource unit (RU) of an OFDMA packet as an OOK modulated signal including a sequence of bit values of 1 and 0. The sequence represents a low-power wake up (LP-WU) packet. The OFDMA packet has a plurality of RUs and is addressed to one or more destination OFDMA devices. The low power baseband processor is to decode an OFDMA symbol allocated to the predetermined RU as a bit value of 1, and to decode an absence of an OFDMA symbol from the predetermined RU as a bit value of 0. The logic is further to cause a wake-up of the main baseband processor based on the LP-WU packet. The main baseband processor may process subsequent OFDMA modulated data symbols as OFDMA modulated data symbols after waking up

Abstract: This disclosure describes systems, methods, and devices related to wireless time sensitive networking. A device may identify, using an 802.3 protocol stack, an 802.3 frame received from a second device using a wired Ethernet connection, and extract, using the 802.3 protocol stack, a redundancy tag from the 802.3 frame, the redundancy tag including a sequence number. The device may generate, using an 802.11 protocol stack, an 802.11 frame with a subnetwork access protocol (SNAP) field, the SNAP field including an organizationally unique identifier (OUI) and the sequence number, the OUI including an indication of an Ethertype protocol. The device may send the 802.11 frame using a wireless connection.
