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.

Abstract: A method for low overhead system information acquisition (LOSIA) is disclosed. The LOSIA method includes several techniques for transmitting common channels in a next generation Radio Access Technology (xRAT). Instead of transmitting system information in a periodic, static, cell-specific, wideband manner, the transmission is triggered by user equipment in an “on demand” manner. The LOSIA method allows the network to control the overhead, bandwidth, and periodicity, as well as other characteristics. The LOSIA method employs several different techniques to trigger the information upon which the network can act, for example, by transmitting different payloads depending on the received trigger.

Abstract: Technology for a user equipment (UE) operable to multiplex uplink control information (UCI) on a physical uplink shared channel (PUSCH) is disclosed. The UE can determine a symbol duration of the PUSCH. The UE can select a UCI transmission rule in accordance with the symbol duration of the PUSCH when a physical uplink control channel (PUCCH) resource carrying UCI overlaps with more than one PUSCH resource in time within a PUCCH group. The UE can multiplex the UCI on a selected PUSCH resource from the more than one PUSCH resource in accordance with the UCI transmission rule.

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 a Next Generation NodeB (gNB) operable to adapt to a downlink waveform type for wireless transmissions is disclosed. The gNB can encode an indicator of a downlink waveform type of a plurality of downlink waveform types for transmission to a user equipment (UE). The gNB can encode 5 a downlink signal for transmission on a downlink physical channel to the UE using the indicated downlink waveform type in a wireless system operating above a 52.6 gigahertz (GHz) carrier frequency.

Abstract: Embodiments of an Evolved Node-B (eNB), User Equipment (UE), and methods for flexible duplex communication are generally described herein. The eNB may transmit a downlink control information (DCI) block to the UE during a group of time-division duplex (TDD) sub-frames. The eNB may further receive an uplink control information (UCI) block from the UE during the group of TDD sub-frames. A first candidate flexible duplex format for the TDD sub-frames may include a downlink control portion and an uplink control portion. A second candidate flexible duplex format for the TDD sub-frames may include a downlink control portion and may exclude uplink control portions.

Abstract: Embodiments of a user equipment (UE) and method for resource allocation and device-to-device (D2D) discovery hopping are generally described herein. In some embodiments, the UE may receive signaling from an enhanced node B (eNB) indicating discovery resources to transmit discovery signals on within an LTE operation zone. The discovery resources may include a discovery zone which may comprise a plurality of physical resource blocks (PRBs) and a plurality of subframes. The UE may transmit a discovery signal for receipt by one or more other UEs for D2D discovery within some of the PRBs of the discovery zone. The PRBs for the transmission of the discovery signal may be determined in accordance with a hopping mode to provide increased frequency diversity within a bandwidth of the discovery zone. The hopping mode may comprise intra-subframe hopping, inter-subframe hopping or joint intra/inter-subframe hopping.

Abstract: In embodiments, a base station may identify a parameter related to a zero power (ZP) resource element (RE) mapping set in a physical resource block (PRB). The ZP RE mapping set may relate to resources that are not to be used to transmit a physical channel transmission. The base station may then transmit, to a user equipment (UE), an indication of the ZP RE mapping set. Other embodiments may be described and/or claimed.
