Abstract: Described is an apparatus of an Evolved Node-B (eNB). The apparatus comprises a first circuitry, a second circuitry, and a third circuitry. The first circuitry associates a first Beam Reference Signal (BRS) for a first Transmit (Tx) beam having a first beamwidth with one or more second BRSes for one or more respectively corresponding second Tx beams having a second beamwidth. The second circuitry generates a first BRS transmission carrying the first BRS, and generates one or more second BRS transmissions carrying the one or more respectively corresponding second BRSes. The third circuitry provides information regarding the first BRS and the second BRSes to the second circuitry.

Abstract: Apparatus that sends uplink control information (UCI) from user equipment (UE) to a network node, generates elements of the UCI including at least one of hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback for one or more uplink (UL) resources, a scheduling request (SR), a channel state information (CSI) report and a beam related information report in response to a trigger set by the network node. The apparatus encodes the UCI elements for transmission via a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) of the one or more UL resources. The one or more UL resources may be UL slots or UL portions of downlink-uplink (DL-UL) slots received from a network node.

Abstract: Technology for a user equipment (UE) using a self-contained scheduling resource to communicate with an eNodeB within a wireless communication network is disclosed. The UE can select, at the UE, a selected eNodeB transmission (Tx) beam and a selected UE reception (Rx) beam based on a highest power beamforming reference signal (BRS) received power (BRS-RP). The UE can signal a transceiver of the UE to transmit to the eNodeB a scheduling request (SR), using the selected Rx beam, on a scheduling request (SR) resource in a self-contained subframe according to a time and frequency location of the selected eNodeB Tx beam. The UE can process an advanced physical downlink control channel (xPDCCH), received from the eNodeB, for an uplink (UL) grant using the selected UE RX beam.

Abstract: 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.

Abstract: User Equipment (UE) and base station (eNB) apparatus and methodology for adjusting receive beamforming. A beam refinement reference signal (BRRS) is transmitted with the same transmit beam direction on which data is to be transmitted. While receiving the BRRS, the receiver varies its receive beam direction and measures a signal characteristic of reception of the BRRS to determine a refined receive beam direction. The refined receive beam direction is used to receive the data.

Abstract: Devices for and methods of providing low latency 5G FDD communications are generally described. A HARQ ACK/NACK for an xPDSCH is transmitted in the xPUCCH of the same or next subframe as the xPDSCH and xPDCCH. An xPUSCH is generated in the same subframe in response to an xPDCCH and HARQ ACK/NACK response is carried by another xPDCCH or xPHICH in the same or next subframe. The xPDCCH and the xPUCCH are at opposite ends of the same subframe, DL and UL subframe are delayed relative to each other, or at least one of the DL and UL subframe has an additional blank portion, portion with data associated with another UE or portion that contains a reference signal, broadcast signal or control information.

Abstract: Devices for and methods of beam refinement using a beam refinement reference signal (BRRS) are generally described. A UE receives BRRS information indicating a BRRS position of at least one OFDM symbol in a first or last symbol pair in a subframe. The BRRS replaces the xPDCCH, the last two symbols of data (an xPDSCH or xPUSCH), or is TDMed with a GP. The data and BRRS are allocated to the UE or to different UEs. The BRRS information is provided via an indicator in the DCI or higher layer signaling. The UE refines either the current Rx beam or directly refines a candidate Rx beam and uses one or multiple symbols, as indicated by a BRRS format.
