Abstract: Techniques for improving CSI (Channel State Information) in connection with FD (Full Dimension)-MIMO (Multiple Input Multiple Output) are discussed. A first set of techniques can employ hierarchical cell common class B CSI-RS for improved beam selection. A second set of techniques can provide improved CSI feedback based on eigenvalue(s) and co-phase associated with a precoder. Various embodiments can employ either or both of the first set of techniques and/or the second set of techniques.

Abstract: Embodiments of enabling a secondary cell in a massive MIMO system are generally described herein. An example apparatus of UE may include memory and processing circuitry to configure a MIMO transceiver to establish primary cell transmit and receive channels for communication with an eNodeB, and to receive a secondary cell addition signal that includes a preamble index for a secondary cell. The processing circuitry further configures the MIMO transceiver to receive beam reference signals (BRS), and select one of the BRS from the eNodeB as a secondary cell transmit channel for the secondary cell based on detected BRS receive power. The processing circuitry further configures the MIMO transceiver to provide information for the selected BRS, and provide xPRACH transmissions that include a transmit index to the eNodeB. The processing circuitry further configures the MIMO transceiver to receive selection of one of the xPRACH transmissions as a secondary cell receive channel.

Abstract: Technology for a wideband coverage enhancement (WCE) user equipment (UE) and a next generation node B (gNB) operable for communication in a MulteFire cell is disclosed. The WCE UE can identify selected resource blocks containing an enhanced physical downlink control channel (ePDCCH), wherein the selected resource blocks are identified using a master information block (MIB). The WCE UE can decode an ePDCCH transmission from the gNB. The WCE UE can identify a system information block MulteFire (SIB-MF) scheduled via the ePDCCH to allow the SIB-MF to be decoded.

Abstract: Technology for a next generation node B (gNB) operable for frequency hopping in MulteFire communications is disclosed. The gNB can perform a clear channel assessment (CCA) for a selected hopping frequency. The gNB can identify a next hopping frequency in a set of hopping frequencies when an energy detection of the CCA is greater than a selected threshold. The gNB can encode data for a downlink transmission at a selected dwell time of a determined hopping frequency in the set of hopping frequencies when an energy detection of the CCA is less than a selected threshold.

Abstract: Machines or networked devices such as internet of things (IoT) devices operate to generate an unlicensed IoT (U-IoT) communication or enhanced Machine Type Communication (eMTC) based on frequency hopping operations on different channels. An anchor channel can be configured to carry system information and paging messages for the U-IoT/eMTC communication on the different channels. The system information and paging messages can include essential system information such as a system information block MulteFire (SIB-MF) message. Physical channels can be configured to enable component carriers anchored to a long term evolution (LTE) licensed band, and entirely comprise unlicensed carrier components that are unanchored to any LTE component carrier in a standalone configuration to enable transmission of the U-IoT communication in standalone communications in an unlicensed band.

Abstract: Devices for and methods of synchronous beam refinement using a beam refinement reference signal (BRRS) are generally described. In one example embodiment, a UE receives BRRS information indicating switching of a Tx beam. The UE then uses this information to switch an associated Rx beam. In some embodiments, timing information is used to match the switching times. In some embodiments, DCI and CSI-RS operations are used to determine switching for the synchronous beam refinement.
