    Abstract: An apparatus of a transmitter may include, for example, a Golay builder to build modulated Golay sequences for at least a non-EDMG Short Training Field (L-STF), and a non-EDMG Channel Estimation Field (L-CEF) of a PPDU; a scrambler to generate scrambled bits by scrambling bits of a non-EDMG header (L-header) and a data field of the PPDU; an encoder to encode the scrambled bits into encoded bits according to a low-density parity-check (LDPC) code; a constellation mapper to map the encoded bits into a stream of constellation points according to a constellation scheme; a spreader to spread the stream of constellation points according to a Golay sequence; and a transmit chain mapper to map a bit stream output from the Golay builder and the spreader to a plurality of transmit chains by applying a spatial expansion with relative cyclic shift over the plurality of transmit chains.

    Abstract: For example, an EDMG STA may generate an LDPC coded bit stream for a user based on data bits for the user in an EDMG PPDU, the LDPC coded bit stream for the user including a concatenation of a plurality of LDPC codewords, a count of the plurality of LDPC codewords is based at least on a codeword length for the user and on a code rate for the user; generate encoded and padded bits for the user by concatenating the LDPC coded bit stream with a plurality of coded pad zero bits, a count of the coded pad zero bits is based at least on a count of one or more spatial streams for the user and on the count of the plurality of LDPC codewords for the user; and distribute the encoded and padded bits for the user to the one or more spatial streams for the user.

    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 systems, methods, and devices related to enhanced multiple-input multiple-output (MIMO) beam refinement protocol (BRP) transmit sector sweep (TXSS). A device may establish a first communication link using a first antenna transmit chain of one or more transmit chains of the initiator, wherein the one or more antenna transmit chains further comprise a second antenna transmit chain. The device may initiate a MIMO BRP TXSS over the one or more antenna transmit chains. The device may map a single space-time stream over the one or more antenna transmit chains. The device may cause to send, to a responder device, an enhanced directional multi-gigabit (EDMG) frame using spatial expansion based on the mapping of the single space-time stream. The device may identify a feedback frame from the responder device. The device may determine one or more antenna weight vectors (AWVs) to use in a MIMO phase of the MIMO beamforming training based on the feedback frame.

    Abstract: Apparatus, computer readable media, and methods for enhanced beamforming training in a wireless local area network are disclosed. An apparatus of a access point or station is disclosed. The apparatus including processing circuitry where the processing circuitry is configured to encode an EBRP packet comprising a first portion comprising an indication of a first number of transmit antenna training settings (N-TX), and an indication of a second number of receive training subfields per N-TX settings (N-RX), and a second portion comprising a third number of training subfields. The third number may be less than or equal to N-TX times N-RX. The processing circuitry may be configured to cause the first portion of the EBRP packet to be transmitted and cause the second portion to be transmitted, where two or more of the third number of training subfields are to be transmitted simultaneously using different antennas and orthogonal sequences.
