Abstract: This disclosure describes the generation and implementation of Golay sequences and Golay Sequence Sets (GSSs) for channel estimation in wireless networks. In one embodiment, this disclosure describes an extension of the Golay sequences Ga and Gb defined in various legacy standards to GSSs. In various embodiments, the disclosed GSSs can include a number of Golay complementary pairs (e.g., Ga and Gb). In one embodiment, the disclosed Golay complementary pairs can meet various predetermined design rules and can be used to define enhanced directional multi-gigabit (EDMG) short training field (STF) and/or channel estimation field (CEF) fields for multiple-input and multiple-output (MIMO) transmission.

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: 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.
