    Abstract: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB), small-cell access point (AP), and methods for dynamic millimeter wave pencil cell communication are generally described herein. The UE may receive access point reference signals (APRS) from one or more small-cell access points (AP), and may transmit APRS signal quality measurements to a macro-cell Evolved Node-B (eNB). The UE may receive, from the macro-cell eNB, a message that indicates candidate pencil cells for which the UE is to determine signal quality measurements, the candidate pencil cells supported by the small-cell APs. The UE may receive beam reference signals (BRS) for the candidate pencil cells and may refrain from reception of BRS for pencil cells not included in the message. In some cases, beam-widths of the APRSs may be larger than beam-widths of the BRSs.

    Abstract: Technology for a user equipment (UE) operable for wideband coverage enhancement is disclosed. The UE can decode downlink control information (DCI) received in a physical downlink control channel (PDCCH). The UE can identify a transport 5 block size (TBS) scaling factor from the DCI. The UE can identify a repetition number from the DCI, wherein the repetition number configures the UE to receive or transmit one or more of data and control channel information that is repeated, in the time domain, a selected number of times based on the repetition number. The UE can encode one or more of data or control information, for transmission to a next generation node B (gNB), based 10 on the TBS scaling factor and the repetition number.

    Abstract: Embodiments of beamformed physical downlink control channel (B-PDCCH) are generally described herein. A user equipment (UE) decodes an indication of a transmission mode for a beamformed physical downlink control channel (B-PDCCH) received from a network entity. The UE decodes one or more symbol blocks corresponding to a downlink (DL) control region of a subframe, wherein the DL control region includes one or more control clusters, and wherein one discrete Fourier transform (DFT) spreading window is applied in each of the one or more control clusters. The UE determines a B-PDCCH search space according to the indicated transmission mode, wherein the B-PDCCH search space is a set of B-PDCCH candidate locations. The UE performs blind decoding of one or more B-PDCCHs based on the determined B-PDCCH search space, to obtain downlink control information transmitted from one or more evolved NodeBs (eNBs) to the UE via the one or more B-PDCCHs.

    Abstract: Described is an apparatus of an Evolved Node-B (eNB) comprising a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to generate a reference signal transmission for an eNB Transmitting (Tx) beam corresponding with at least a first eNB antenna port having a first polarization and a second eNB antenna port having a second polarization. The second circuitry may be operable to process one or more reporting transmissions carrying at least one of a first signal reception indication for a first UE antenna port and a second signal reception indication for a second UE antenna port. The third circuitry may be operable to determine a transmission hypothesis based upon the one or more reporting transmissions.

    Abstract: Disclosed herein are apparatuses, systems, and methods for reference signal design for initial acquisition, by receiving a first primary synchronization signal (PSS) and a first secondary synchronization signal (SSS) from a first transmit (Tx) beam, in first contiguous orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A UE can receive at least a second PSS and a second SSS from a second Tx beam in contiguous OFDM symbols of the downlink subframe. A UE can then detect beamforming reference signals (BRSs) corresponding to the first Tx beam and the second Tx beam, based on identification of physical cell ID information and timing information processed from the first PSS, the second PSS, the first SSS, and the second SSS. The UE can select the first Tx beam or the second Tx beam that was received with the highest power, based on the BRSs. Other embodiments are described.

    Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K x a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

The UE can select one or more uplink (UL) partial subframe configurations based on one or more prospective lengths of a listen before talk (LBT) period, wherein each prospective length of the LBT period provides a prospective starting time. The UE can encode data for each of the one or more UL partial subframe configurations to form one or more UL partial subframe configuration encodings. The UE can identify an actual LBT period. The UE can select one of the one or more UL partial subframe configuration encodings for UL transmission of the data on the unlicensed carrier based on the actual LBT period and a corresponding prospective starting time.

    Abstract: Embodiments described herein include devices, methods, and instructions for managing beam interpolation in massive multiple-input multiple-output (MIMO) communications. In one example embodiment, an evolved node B is configured to transmit to a UE using massive MIMO by transmitting multiple beamformed reference signals on multiple transmission beams each associated with a different plurality of antennas. The eNB receives beam interpolation information back from the UE, and then generates a data transmission that is sent to the UE using an interpolated transmission beam from a first and second transmission beam.
