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) in accordance with an enhanced PHY layer protocol. The PPDU may be encoded for transmission in a dedicated short-range communication (DSRC) frequency band. The NGV STA may encode the PPDU to include a preamble, one or more data portions, and one or more midambles. The one or more midambles may occur within the PPDU after the preamble and after at least one of the data portions. The NGV STA may encode a preamble that includes an NGV SIG-A field that indicates: whether the PPDU includes the one or more midambles, and a periodicity of the one or more midambles.

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The STA may determine a portion of a channel occupied by an incumbent device. The STA may refrain from communication in a first subset of resource units (RUs) that overlap the portion of the channel occupied by the incumbent device. The STA may determine a combined RU that comprises two or more RUs of a second subset of RUs that do not overlap the portion of the channel occupied by the incumbent device. The STA may encode a physical layer convergence procedure protocol data unit (PPDU) for transmission in the combined RU. The PPDU may be encoded in accordance with joint coding across the RUs of the combined RU.

Abstract: For example, an apparatus may be configured to cause an Access Point (AP) Multi-Link Device (MLD) to, during an ongoing communication between a first AP of the AP MLD and a first non-AP wireless communication station (STA) over a first wireless communication channel, communicate a suspend request by a second AP of the AP MLD over a second wireless communication channel, the suspend request configured to request suspension of the ongoing communication between the first AP of the AP MLD and the first non-AP STA; to suspend the ongoing communication between the first AP of the MLD and the first non-AP STA over the first wireless communication channel for a suspension period; and to communicate a frame by the first AP over the first wireless communication channel during the suspension period, the frame communicated between the first AP and a second non-AP STA.

Abstract: This disclosure describes systems, methods, and devices related to wake up receiver (WUR) frequency division multiple access (FDMA) transmission. A device may cause to send a wake up receiver (WUR) beacon frame on a WUR beacon operating channel to one or more station devices. The device may determine a first wake-up frame to be sent on a first WUR operating channel, wherein the first WUR operating channel is associated with one or more frequency division multiple access (FDMA) channels used for transmitting one or more wake-up frames to the one or more station devices. The device may determine to apply padding to the first wake-up frame based on a field included in a header of the first wake-up frame. The device may cause to send the first wake-up frame to a first station device of the one or more station devices.

Abstract: This disclosure describes systems, methods, and devices related to wake-up radio (WUR) advertisement channels. A device may include a wake-up receiver (WURx) and a primary connectivity radio. The device may determine a wake-up radio (WUR) discovery subchannel for WUR advertisement. The WUR discovery subchannel may be associated with a channel of a frequency band. The device may generate a WUR discovery frame comprising a WUR advertisement. The device may transmit, by the WURx, the WUR discovery frame to a second device using the WUR discovery subchannel. The device may identify a response from the second device indicating an acknowledgment of the WUR discovery frame.
