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 (PHY) 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: 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: 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.
