Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a Physical Layer Protocol Data Unit (PPDU). For example, an Enhanced Directional Multi-Gigabit (DMG) (EDMG) station (STA) may be configured to encode a Physical Layer (PHY) Service Data Unit (PSDU) of at least one user in an EDMG PM Protocol Data Unit (PPDU) according to an EDMG Low-Density Parity-Check (LDPC) encoding scheme, which is based at least on a count of one or more spatial streams for transmission to the user; and transmit the EDMG PPDU in a transmission over a channel bandwidth in a frequency band above 45 Gigahertz (GHz).

Abstract: For example, an EDMG STA may be configured to receive an A-MPDU for the EDMG STA in an EDMG MU PPDU from an EDMG MU-MIMO initiator station; to determine, according to an ordered acknowledgement scheme, a Block Acknowledgement (BA) period in which the EDMG STA is to be awake to allow transmission of a BA from the EDMG STA to the EDMG MU-MIMO initiator STA; to allow the EDMG STA to be in a power save mode during a first power save period from a time of an End of Frame (EOF) field in the A-MPDU for the EDMG STA until a beginning of the BA period; to transmit the BA to the EDMG MU-MIMO initiator; and to allow the EDMG STA to be in the power save mode during a second power save period after transmission of the BA.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating an Enhanced Directional Multi-Gigabit (DMG) (EDMG) Physical Layer Protocol Data Unit (PPDU). For example, an EDMG wireless communication station (STA) may be configured to communicate an EDMG PPDU including a Channel Estimation Field (CEF) and/or a pilot sequence, which may be configured for an OFDM mode.

Abstract: For example, a first Enhanced Directional Multi-Gigabit (DMG) (EDMG) station (STA) may be configured to exchange first and second Beam Refinement Protocol (BRP) setup frames with a second EDMG STA to initiate a BRP Transmit Sector Sweep (TXSS) over an aggregated channel bandwidth including an aggregation of a primary channel and a secondary channel in a frequency band above 45 GHz; during the BRP TXSS, transmit a plurality of BRP frames to the second EDMG STA over the primary channel and the secondary channel according to an EDMG control mode; determine a transmit beamforming configuration over the aggregated channel bandwidth based on BRP feedback from the second EDMG STA; and transmit an EDMG Physical Layer (PHY) Protocol Data Unit (PPDU) to the second EDMG STA over the aggregated channel bandwidth based on the transmit beamforming configuration.

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: 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 (LDDC) 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.
