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: Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a first Downlink Control Information (DCI) format 0A transmission indicating a Grant-less Uplink (GUL) activation. The first circuitry may also be operable to process a second DCI format 0A transmission indicating a GUL release. The second circuitry may be operable to generate one or more Uplink (UL) transmissions for an unlicensed spectrum of the wireless network after the GUL activation and before the GUL release.

Abstract: In embodiments, a base station may be able to identify whether a user equipment (UE) is to operate within the cellular network in accordance with a wideband (WB) protocol or a narrowband (NB) protocol. Based on this identification, the base station may further be able to identify a number of resource blocks (RBs) that include subcarriers occupied by enhanced narrowband control channel elements (eNCCEs). Finally, the base station may be able to transmit the eNCCEs on the subcarriers. Other embodiments may be described and/or 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: 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: The disclosure describes design of a synchronization signal (SS) block for an unlicensed carrier, and listen before talk (LBT) strategies for initial access. An apparatus of a radio access network (RAN) is disclosed. The apparatus includes baseband circuitry that includes one or more processors and a radio frequency (RF) interface. The one or more processors are to generate, for user equipment (UE) operating on a licensed assisted access (LAA) secondary cell (SCell), a data sequence associated with an SS block. The SS block includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), but does not include a physical broadcast channel (PBCH). The RF interface is to receive the data sequence from the one or more processors.

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.

Abstract: Embodiments of an Evolved Node-B (eNB), User Equipment (UE) and methods for communication are generally described herein. The eNB may receive, from a UE, uplink control information (UCI) that indicates a hybrid automatic repeat request identifier (HARQ ID) for a grant-less uplink (GUL) transmission by the UE during a first sub-frame. The eNB may select, from candidate HARQ IDs, a HARQ ID for a scheduled uplink (SUL) transmission by another UE in a second sub-frame after the first sub-frame. The eNB may, if the GUL transmission is successfully decoded, include the HARQ ID for the GUL transmission in the candidate HARQ IDs for the GUL transmission. The eNB may, if the GUL transmission is not successfully decoded, exclude the HARQ ID for the GUL transmission from the candidate HARQ IDs for the GUL transmission.
