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 tone mapping for a high-efficiency (HE) trigger-based (TB) null data packet (NDP) feedback physical layer protocol data unit (PPDU). A device may identify a frame received from a second device. The device may determine, based on the frame, a resource unit allocated to the device, wherein the resource unit is associated with a 20 MHz sub-channel of a bandwidth. The device may determine, based on the resource unit and the bandwidth, tones associated with a HE short training field (HE-STF) of a HE TB NDP feedback PPDU. The device may send the HE TB NDP feedback PPDU to the second device in the 20 MHz sub-channel, wherein the HE TB NDP feedback PPDU includes the tones.

Abstract: Embodiments of an AP and wake up radio (WUR) non-AP station (STA) are generally described herein. The AP may transmit a WUR packet to wake up a wireless local area network (WLAN) radio of the WUR non-AP STA. A non-WUR portion of the WUR packet may include legacy fields and a BPSK mark to spoof high throughput (HT) devices receiving the WUR packet. The AP may transmit the BPSK mark in a channel that includes a lower guard band, a transmission bandwidth, and an upper guard band. The AP may encode the BPSK mark in accordance with: on-off keying (OOK) modulation in a center portion of the transmission bandwidth; and orthogonal frequency division multiplexing (OFDM) in a remaining portion of the transmission bandwidth that excludes the center portion.
