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 PHY 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: For example, an Enhanced Directional Multi-Gigabit (EDMG) initiator station (STA) of a Beam Refinement Protocol (BRP) Transmit (TX) Sector Sweep (SS) (TXSS) may be configured to, during an initiator BRP TXSS, transmit one or more initiator EDMG BRP-TX packets to an EDMG responder STA; during a responder BRP TXSS following the initiator BRP TXSS, to receive one or more responder EDMG BRP-TX packets from the EDMG responder STA; and to transmit to the EDMG responder STA a BRP frame including feedback based on measurements on the one or more responder EDMG BRP-TX packets.

Abstract: In a radio-access network utilizing beam-formed communications, beam direction for uplink or downlink communications is determined based on learned beam directions applicable to a current location of user equipment (UE) in lieu of a sector scan when prior transmission performance measures are available for the current location. A beam-finding map that associates a plurality of locations with corresponding beam directions previously determined to be operative to direct transmission from those locations to a recipient device is used.

Abstract: Sector sweeps are described for establishing two-way data communications with directional antennas. Some examples receive a sequence of base station transmit sector sweep signals from a base station (BS) at the UE, each signal being transmitted to a different transmit sector from a multiple antenna array of the BS, select a best transmitted signal at the UE from among the received signals, send a sequence of UE transmit sector sweep signals to the base station from the UE, each signal being transmitted to a different transmit sector from a multiple antenna array of the UE, send an identification of the selected best base station transmit sector sweep signal to the base station, receive an identification of a selected best UE transmit sector sweep signal from the base station, and send data to the BS using the identified best UE transmit sector.

Abstract: This disclosure describes systems, methods, and devices related to transmit power control (TPC). A device may identify a link measurement request frame from a first station device. The device may determine, for each transmit chain of the first station device, a TPC action to be performed by the first device. The device may cause to send a link measurement report frame comprising a value indicative of the TPC action for each transmit chain. The device may identify an acknowledgement from the first station device.
