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.

Apparatus, system and method of communicating an EDMG PPDU

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.

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.

This disclosure describes systems, methods, and devices related to scheduled multi-user multiple-input multiple-output (MU-MIMO) acknowledgement. A device may determine a block acknowledgment schedule associated with one or more destination devices. The device may cause to send a multi-user multiple-input multiple-output (MU-MIMO) frame including the block acknowledgment schedule. The device may identify one or more acknowledgment frames received from at least one of the one or more destination devices based on the block acknowledgment schedule.

Signaling for scheduled multi-user multiple-input multiple-output acknowledgement

Techniques are disclosed for implementing am Intelligent Distributed Relay (IDR). The IDR may advantageously use the best qualities of both amplify-and-forward and decode-and-forward solutions. The advantageously leverages the use of a digital signal processing (DSP) circuitry, which may decode the data and control information. The control information may be used to control IDR behavior (e.g., in the uplink and/or downlink directions) and to enhance its characteristics.

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 (LDPC) 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.

Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.

Channel quality information feedback techniques

For example, an EDMG initiator STA of an asymmetric beamforming training may be configured to, during a Beacon Transmission Interval (BTI) in a Beacon Interval (BI), transmit a beacon via a sector of the EDMG initiator STA, the beacon including allocation information to allocate a beamforming training allocation for asymmetric beamforming training of the sector during a Data Transfer Interval (DTI) in the BI after the BTI, the beacon including one or more Receive Training (TRN-R) subfields for the asymmetric beamforming training of the sector; during the beamforming training allocation, to listen on the sector for one or more Sector Sweep (SSW) frames from one or more EDMG responder STAs; and, during the beamforming training allocation, to transmit via the sector a sector acknowledgement (ACK) frame including information based on the one or more SSW frames.

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.
