Abstract: Technology for a Next Generation NodeB (gNB) operable to communicate over an anchor channel for Unlicensed Internet of Things (U-IoT) is disclosed. The gNB can encode control information for periodic transmission on a set frequency of an anchor channel for U-IoT in an adaptive frequency hopping system. The anchor channel can include a clear channel assessment (CCA) period, an extended CCA (eCCA) period when a failure occurs during the CCA period, a tuning period for radio frequency (RF) retuning with frequency hopping, and a control information communication period for communication of the control information.

Abstract: Embodiments of an Evolved Node-B (eNB), User Equipment (UE) and methods for communication are generally described herein. The eNB may encode an enhanced physical downlink control channel (ePDCCH) for transmission in a sub-frame in first physical resource blocks (PRBs). The ePDCCH may indicate: a transmission of a physical downlink shared channel (PDSCH) in accordance with a wideband coverage enhancement (WCE), and second PRBs to be used for the transmission of the PDSCH. The eNB may encode the PDSCH for transmission. The eNB may configure transceiver circuitry to transmit the PDSCH in a plurality of subframes, wherein transmission of the PDSCH is repeated in each sub-frame of the plurality of sub-frames in the second PRBs as part of the WCE. The ePDCCH may be transmitted in a starting sub-frame of the plurality in the first PRBs.

Abstract: Provided herein are method and apparatus for cross retransmission between Grant-less Uplink transmission (GUL) and Scheduled Uplink transmission (SUL). An embodiment provides an apparatus for a user equipment (UE) comprising baseband circuitry including one or more processors to: encode an uplink (UL) transmission data for transmission to an evolved Node B (eNB) on an un-licensed spectrum; determine a mode of re-transmission for the UL transmission as a scheduled mode in which the re-transmission is based on a re-transmission grant derived from downlink control information (DCI) received from the eNB or a grant-less mode in which the re-transmission is performed without the re-transmission grant from the eNB; and encode the re-transmission of the UL transmission based on the determined mode. Also provided is hybrid automatic repeat request (HARQ) feedback for GUL and SUL. At least some embodiments allow for maximum channel occupancy time (MCOT) sharing.

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 for and methods of beam refinement using a beam refinement reference signal (BRRS) are generally described. A UE receives BRRS information indicating a BRRS position of at least one OFDM symbol in a first or last symbol pair in a subframe. The BRRS replaces the xPD-CCH, the last two symbols of data (an xPDSCH or xPUSCH), or is TDMed with a GP. The data and BRRS are allocated to the UE or to different UEs. The BRRS information is provided via an indicator in the DCI or higher layer signaling. The UE refines either the current Rx beam or directly refines a candidate Rx beam and uses one or multiple symbols, as indicated by a BRRS format.
