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: Techniques related to physical uplink control channel procedures are described. Briefly, in accordance with one embodiment, an Uplink Control Information (UCI) payload size is determined based at least in part on configuration information and Downlink Control Information (DCI). A Fifth Generation (5G) Physical Uplink Control Channel (xPUCCH) format is then determined based at least in part on the determined UCI payload size. Other embodiments are also disclosed and claimed.

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: 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: An apparatus of a user equipment (UE) may include a memory and one or more processors operatively coupled to the memory. The processors may process a scheduling trigger to provide channel state information (CSI) and beam information using extra-large physical uplink shared channel (xPUSCH). The processing device may also generate a reporting message comprising CSI and beam information. The processing device may then encode xPUSCH data to include the reporting message.

Abstract: Technology for a user equipment (UE) operable to report channel quality indication (CQI) information to a Next Generation NodeB (gNB) in a wideband coverage enhancement (WCE) for MulteFire system is disclosed. The UE can decode a coding rate scaling factor received from the gNB in the WCE for MulteFire system. The UE can measure a channel between the gNB and the UE. The UE can calculate a modulation and coding rate based on the channel measurement between the gNB and the UE. The UE can scale the modulation and coding rate using the coding rate scaling factor to form a scaled modulation and coding rate. The UE can select a CQI index that corresponds to the scaled modulation and coding rate. The UE can encode the CQI index for transmission to the gNB in a channel state information (CSI) report.

Abstract: Devices and methods of simultaneous data reception and measurement are generally described. A UE transmits to an eNB antenna capacity and receives a Beamformed Reference Signal (BRS) configuration in response. Beamformed signals from the eNB include a BRS subframe in accordance with the BRS configuration. The BRS subframe has a BRS whose structure depends on the UE antenna capacity. If the UE has a single antenna panels, neither an EPDCCH nor a PDSCH for the UE is in the BRS frame. If the UE has a single antenna panels and multiple ports or multiple antenna panels, the BRS may contain an EPDCCH or PDSCH for the UE as different ports or antenna panels may be assigned different functionality. The UE measures BRS Received Power (BRS-RP) of the BRS, transmits a BRS report based on the BRS-RP and selects an optimal beam based on BRS-RPs from BRSs of the beams.
