Abstract: Embodiments of an access point (AP) station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN) (i.e., EHT) are generally described herein. In some embodiments, a comb resource unit (RU) structure may be used to distribute tones of an RU across a wider bandwidth for narrow RU power spectral density (PSD) boosting for longer-range transmission in EHT to meet ETSI and/or FCC limitations.

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: This disclosure describes systems, methods, and devices related to extreme high throughput (EHT) data scrambler. A device may determine an extreme high throughput (EHT) data field of a frame to be scrambled using an EHT data scrambler. The device may determine to initialize the EHT data scrambler using an initialization seed, wherein the initialization seed has a size greater than seven bits. The device may generate scrambled data using the initialization seed. The device may cause to send the frame comprising the scrambled data to a first station device.

Abstract: This disclosure describes systems, methods, and devices related to secure sounding signal. A device may generate two or more sounding signals to be sent using two or more antennas to a receiving device across a plurality of symbol intervals. The device may apply a first masking signal to a first sounding signal of the two or more sounding signals over a first symbol interval of the plurality of the symbol intervals. The device may apply a second masking signal to a second sounding signal over a second symbol interval of the plurality of the symbol intervals. The device may cause to send the two or more sounding signals to receiving device using the two or more antennas.

Abstract: This disclosure describes systems, methods, and devices related to enhanced tone allocation. A device may schedule a number of station devices to be included in a physical layer (PHY) protocol data unit (PPDU) for a multiple-user multiple-input multiple-output (MU-MIMO) transmission. The device may limit a number of resource units (RUs) to be used in the PPDU for the MU-MIMO transmission. The device may use a minimum RU size to be at least 242 tones for the MU-MIMO transmission. The device may cause to send the PPDU to the number of station devices.

Abstract: This disclosure describes systems, methods, and devices related to enhanced constellation shaping. A device may generate payload bits associated with a frame to be sent to a first station device. The device may generate a first output bits having a first length based on the application of a first mask of one or more masks to the payload bits. The device may generate a second output bits having a second length based on the application of a second mask of the one or more masks. The device may compare the first length of the first output bits to the second length of the second output bits. The device may select the first mask or the second mask based on the comparison. The device may convert the payload bits using the selected mask before passing through a shaping encoder to generate shaped bits. The device may cause to send the frame bits and an indication of the selected mask to the first station device.
