Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating an Enhanced Directional Multi-Gigabit (DMG) (EDMG) Orthogonal Frequency-Division Multiplexing (OFDM) Physical layer (PHY) Protocol Data Unit (PPDU). For example, an EDMG station (STA) may be configured to generate an EDMG OFDM PPDU including at least a non-EDMG header (L-Header), an EDMG header, and a data field, the EDMG header including a spoofing error length indicator field configured to indicate whether or not a spoofing error of the EDMG OFDM PPDU is less than one OFDM symbol duration; and to transmit the EDMG OFDM PPDU over a channel bandwidth in a frequency band above 45 Gigahertz (GHz).

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 PHY 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, 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 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: 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 generate a Physical Layer (PRY) PPDU; generate one or more PPDU waveforms corresponding to one or more respective transmit chains for digital beamforming transmission of the PPDU; and transmit the PPDU via the one or more transmit chains over a channel bandwidth of at least 2.16 Gigahertz (GHz) in a frequency band above 45 GHz.

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.
