Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a PPDU including a training field. For example, an Enhanced Directional Multi-Gigabit (DMG) (EDMG) wireless communication station may be configured to determine one or more Orthogonal Frequency Division Multiplexing (OFDM) Training (TRN) sequences in a frequency domain based on a count of one or more 2.16 Gigahertz (GHz) channels in a channel bandwidth for transmission of an EDMG PPDU including a TRN field; generate one or more OFDM TRN waveforms in a time domain based on the one or more OFDM TRN sequences, respectively, and based on an OFDM TRN mapping matrix, which is based on a count of the one or more transmit chains; and transmit an OFDM mode transmission of the EDMG PPDU over the channel bandwidth, the OFDM mode transmission comprising transmission of the TRN field based on the one or more OFDM TRN waveforms.

Abstract: This disclosure describes systems, methods, and devices related to a distributed relay. The distributed relay may utilize beamforming and/or a specific physical arrangement of transmit and receive antennas to ensure a high isolation between antennas. The distributed relay may further facilitate the concurrent operation of two different intermediate frequency (IF) chains to support communications between a network entity and user device, receiving and transmitting data on each of the two IF chains independently of one another.

Abstract: This disclosure describes methods, apparatus, and systems related to media access control (MAC) range extension. A device may cause to append a training field to each of one or more beacon frames. The device may cause to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval. The device may determine an extended schedule element to be sent to the one or more responder devices, the extended schedule element including one or more directional antenna sectors to be used by the device during a second interval. The device may identify a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device.

Abstract: This disclosure describes systems, methods, and devices related to using enhanced acknowledgment and power save. A device may determine a multi-user (MU) multiple-input multiple-output (MIMO) frame associated with a MU-MIMO group. The device may determine a first portion of the MU-MIMO frame associated with the first station device of the MU-MIMO group, wherein the first portion comprises a first indication of a first time offset associated with the first station device. The device may determine a second portion of the MU-MIMO frame associated with the second station device of the MU-MIMO group, wherein the second portion comprises a second indication of a second time offset associated with the second station device. The device may cause to send the MU-MIMO frame to the MU-MIMO group. The device may identify a first acknowledgment from the first station device based on the first time offset.

Abstract: Communication signals using a first and a second frequency band in a wireless network is described herein. The first frequency band may be associated with a first beamwidth while the second frequency band may be associated with a second beamwidth. An apparatus may include receiver circuitry arranged to receive first signals in a first frequency band associated with a first beamwidth and second signals in a second frequency band associated with a second beamwidth, the first signals comprising a frame synchronization parameter and the second signals comprising frame alignment signals. The apparatus may further include processor circuitry coupled to the receiver circuitry, the processor circuitry arranged to activate or deactivate the receiver circuitry to receive the frame alignment signals based on the frame synchronization parameter.
