    Abstract: For example, an Enhanced Directional Multi-Gigabit (DMG) (EDMG) wireless communication station (STA) may be configured to scramble, according to a first scrambling sequence, a plurality of EDMG Header B bits of an EDMG Header B field of an EDMG Multi-User (MU) Physical Layer (PHY) Protocol Data Unit (PPDU) into a plurality of scrambled header bits; generate a Low-Density Parity-Check (LDPC) codeword based on the plurality of scrambled header bits; determine a data block based on the LDPC codeword; generate one or more scrambled data blocks based on the data block by scrambling the data block according to a second scrambling sequence; and transmit a wireless transmission of the EDMG Header B based on the one or more scrambled data blocks.

    Abstract: For example, an EDMG STA may be configured to generate a plurality of spatial streams of an EDMG PPDU; map the plurality of spatial streams to a respective plurality of pairs of space-time streams according to an STBC scheme by mapping a first data sequence of a spatial stream to a first symbol in an odd numbered space-time stream, mapping a second data sequence of the spatial stream to a second symbol in the odd numbered space-time stream, mapping a sign inverted complex conjugate of the second data sequence to a first symbol in an even numbered space-time stream, and mapping a complex conjugate of the first data sequence to a second symbol in the even numbered space-time stream; and transmit a transmission comprising the plurality of pairs of space-time streams over a channel bandwidth in a frequency band above 45 Gigahertz (GHz).

    Abstract: This disclosure describes methods, apparatus, and systems related to a modulation and coding scheme (MCS) system. The device may determine a wireless communications channel with a first device in accordance with a wireless communications standard. The device may generate a header in accordance with a communication standard, the header including, at least in part, a modulation and coding scheme (MCS) index value. The device may determine a code rate associated with the MCS index value based at least in part on the wireless communications channel. The device may cause to send the header to the first device over the wireless communications channel based at least in part on the MCS index value.

    Abstract: This disclosure describes methods, devices, and systems related to interleaving and deinterleaving symbols used in single carrier modulation and coding schemes. A device is disclosed comprising at least one memory storing computer-executable instructions, and at least one processor configured to access the at least one memory. The at least one processor is further configured to execute the computer-executable instructions to: receive a source data bit string from the at least one memory, scramble the source data bit string, parse the scrambled source data bit string into a plurality of segments, assign a portion of the plurality of segments to a Single Carrier-Block (SC-BLK), and encode the portion of the plurality of segments into a code word, wherein the code word comprises a plurality of bit groups, and each bit group comprises one or more bits. The at least one processor is further configured to determine a number of modulation symbols based at least in part on group size; map each of the plurality of bit groups to a corresponding modulation symbol; group the modulation symbols into an interleaved symbol block associated with the SC-BLK; group the plurality of modulation symbols in the interleaved symbol block into a second code word that corresponds to the first code word; and transmit a packet comprising the interleaved symbol block.
