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 PM 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: 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: Embodiments relate to network management of a wireless network in which inactive cells are selectively activated thereby changing the radio environment of a user equipment. The changed radio environment is assessed to determine a preferred distribution of active cells for that user equipment.

For example, a station may generate a plurality of space-time streams including at least a first space-time stream and a second space-time stream, the first space-time stream including, in a first interval, a first data sequence followed by a first Guard Interval (GI) sequence, the second space-time stream including, in the first interval, a second data sequence followed by a second GI sequence, the first space time stream comprising, in a second interval subsequent to the first interval, a sign-inverted and time-inverted complex conjugate of the second data sequence followed by the first GI sequence, the second stream including, in the second interval, a time-inverted complex conjugate of the first data sequence followed by the second GI sequence; and transmit a SC STBC transmission based on the plurality of space-time streams.
