Abstract: Systems, devices, and techniques for indicating the number of repetitions for a downlink control information (DCI) message are described. A described technique includes transmitting an indication of a repetition number for a downlink control information (DCI) message having a predetermined format for transmit power control (TPC) of an uplink channel by a user equipment (UE); and transmitting, to the UE via a machine-type communications physical downlink control channel (MPDCCH), repetitions of the DCI message in accordance with the predetermined format and in accordance with the repetition number. The predetermined format can based on a DCI format 3 or 3A for bandwidth-reduced low-complexity or coverage enhanced (BL/CE) UEs.

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.
