Abstract: Embodiments of dynamic multiplexing are described, including the transmission of preemption indication (PI) to indicate preemption of time-frequency resources. In some embodiments, a next Generation NodeB (gNB) is configured to transmit PIs in signaling to preempt an enhanced Mobile Broadband (eMBB) communications transmission with an ultra-reliable and low latency communications (URLCC) transmission. In some embodiments, a user equipment (UE) is configured to monitor a region of time-frequency resources, within a bandwidth part (BWP), for a PI. The PI indicates to the UE a portion of time-frequency resources that omit transmissions intended for the UE. In some embodiments, the gNB transmits the PI to the UE within preemption indication downlink control information (PI-DCI) in a physical downlink control channel (PDCCH) in a control resource set (CORESET). In some embodiments, the BWP is defined according to a frequency domain location, a bandwidth, and a subcarrier spacing for a given numerology.

Abstract: A device of a New Radio (NR) User Equipment (UE), a system, a method and a machine-readable medium. The device includes a radio frequency (RF) interface, and a processing circuitry coupled to the RF interface, the processing circuitry to: decode a message from a NR Node B (gNodeB), the message corresponding to a unicast message or to a broadcast message and being received through a Universal Mobile Telecommunications System (UMTS) interface (Uu interface), the message further including reference time information; and determine a reference time from the reference time information, the reference time to be used by higher layers of the UE.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Abstract: Embodiments of a Machine Type Communication User Equipment (MTC UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The MTC UE may determine a system timing based on reception of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The MTC UE may receive, from the gNB, radio resource control (RRC) signaling that indicates one or more parameters of a configurable resynchronization signal (RSS). The RSS may be for resynchronization, by the MTC UE, after the MTC UE awakens from a power save mode. The parameters of the RSS in the RRC signaling may depend on a target coverage of the MTC UE. The MTC UE may determine an updated system timing based on reception of the RSS.

Abstract: Embodiments of a User Equipment (UE) and methods for device-to-device (D2D) communication are generally described herein. In some embodiments, the UE may transmit a scheduling assignment (SA) control message that indicates time transmission intervals (TTIs) to be used for a D2D transmission of a data payload by the UE to a receiving UE during an SA cycle. The UE may transmit the data payload during the TTIs indicated in the SA control message. The TTIs used for the transmission of the data payload may be included in a group of D2D TTIs reserved for D2D transmissions. In some embodiments, a time resource pattern for transmission (T-RPT) may indicate a sequence of TTI indexes for the TTIs used for the transmission of the data payload.

Abstract: Cellular (e.g., LTE or UMTS) and global navigation satellite system (GNSS) based technologies can provide ubiquitous and seamless synchronization solution for LTE-based vehicle to everything (V2X) or Proximity Services synchronization (ProSe) services. For example, by using joint GNSS timing references and LTE cellular network timing references for V2X or ProSe system synchronization benefits of using GNSS technologies to improve synchronization procedure for LTE based V2X or ProSe services can be enabled, including: (1) accurate and stable timing, (2) availability of a global and stable timing reference and (3) ability to propagate GNSS timing by user equipment having sufficient GNSS signal quality.
