    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 multiple-input multiple-output (MIMO) channel access. A device may determine one or more time division duplex (TDD) service periods (SPs). The device may determine a directional multi-gigabit (DMG) frame to be sent to a responder device on a channel associated with a MIMO communication. The device may cause to send the DMG frame to the responder device on the channel. The device may establish a MIMO channel access based on sending the DMG frame to the responder device.

    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.

    IPC: H04W4/02

    Abstract: Methods, apparatuses, and computer readable media for report identification and power control for multi-device wireless sensing in a wireless network are disclosed. An apparatus of an access point (AP) is disclosed, where the apparatus comprises processing circuitry configured to encode for transmission to a station (STA) a frame comprising a configuration hold subfield, the hold subfield indicating whether the STA should maintain a transmit configuration unchanged during uplink (UL) sensing. The processing circuitry further configured to encode for transmission a trigger frame (TF) for sensing, the TF for sensing including an identification of the STA, an indication of a resource unit (RU) for the STA to use to transmit an uplink (UL) sensing packet, and TF type subfield, the a TF type subfield indicating the TF for sensing.

    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 (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.
