    Abstract: Technology for a user equipment (UE) operable to communicate with an one or more extended transmission reception points (TRPs) is disclosed. The UE can signal a transceiver of the UE to simultaneously broadcast two or more transmission beams to establish a connection with one or more of an extended eNodeB or one or more extended transmission reception points (TRP), wherein each extended TRP is connected to the UE via an extended interface with the extended eNodeB. The UE can decode, at the UE, higher layer signaling received from the one or more extended TRPs to form beam association, beam addition, beam release, beam change, or a combination thereof between the UE and the one or more extended TRPs.

    Abstract: Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) comprises one or more baseband processors to decode one or more channel state information reference signals (CSI-RS) received from an evolved Node B (eNB) using open loop full-dimension multiple input, multiple output (FD-MIMO), and to generate feedback to the eNB responsive to the one or more CSI-RS signals, and a memory to store a Class A codebook from which the feedback is generated, wherein the feedback includes an i1 codebook index of the Class A codebook and a channel quality indicator (CQI) determined based at least in part on i2 codebook index cycling across one or more physical resource blocks (PRBs). In some embodiments, Class B feedback using a Class B codebook by be utilized.

    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: 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 establish that Downlink (DL) transmissions from a second Evolved Node-B (eNB) will interfere in one or more subframes with Uplink (UL) transmissions from the UE to a first eNB. The second circuitry may be operable to modulate a UL transmission power based upon the established interference condition.

    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.

    Abstract: Technology for decreasing latency for contention based scheduling request (SR) is disclosed. A user equipment (UE) can randomly select a physical random access channel (PRACH) preamble index for a PRACH transmission. The UE can multiplex the PRACH preamble index together with a SR message containing a cell radio network temporary identifier (C-RNTI) and a buffer status report (BSR) for the PRACH transmission. The UE can process, for transmission, to an enhanced node B (eNB), the PRACH preamble index multiplexed with the SR message in a subframe #(n) of the PRACH transmission, wherein n is a subframe number.
