    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.

    Abstract: An apparatus and system for decreasing packet error rate (PER) in a station (STA) are described. The STA determines that an Extremely High Throughput (EHT) physical layer protocol data unit (PPDU) is to be constructed for transmission and that Low-Density Parity-Check (LDPC) encoding is to be used to encode a data field of the EHT PPDU. In response, the STA constructs the EHT PPDU in accordance with a construction constraint of the data field of the EHT PPDU when a LDPC codeword (CW) size 648 is to be used for the data field of the EHT PPDU. The construction constraint includes using bit level interleaving or preventing use of LDPC CW size 648 for a modulation coding scheme (MCS) that is larger than 256 quadrature amplitude modulation (QAM) or 64 QAM or for all QAMs.

    Abstract: Techniques are disclosed for determining customized frequency rotation values for a number of wireless channel configurations. The channel configurations may define various parameters of a wireless channel in accordance with a communication protocol, such as the channel bandwidth, the number of sub-channels, and which of the sub-channels may be punctured. The frequency rotation values may be obtained by determining the Peak to Average Power Ratio (PAPR) values for different combinations of frequency rotation values that are applied to the sub-channels of the wireless channel on a per-configuration basis. Thus, for each configuration, the lowest maximum PAPR or other suitable threshold value may be used to identify the frequency rotation values for that particular configuration. The frequency rotation values may then be applied at run time based upon the current wireless channel configuration for data transmissions via the wireless channel.

    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.
