    Abstract: A base station belonging to a first cell group (CG) that includes a transceiver configured to connect to a user equipment (UE) and a processor configured to transmit a command to the UE to perform a BWP switch, and monitor a physical uplink control channel (PUCCH) for an acknowledgement or a negative acknowledgement (ACK/NACK) for a predetermined period of time, wherein the predetermined period of time is the sum of a standard-defined period of time between transmission of a radio resource control (RRC) command and receipt of the ACK/NACK, a time to process an RRC command, and a time to perform a BWP switch.

    Abstract: An approach for wireless communications to support reduced capability New Radio (NR) with larger available control resource sets (CORESET) bandwidths. Examples include a frequency-hopping CORESET with a predefined hopping pattern configured by higher layers, such as RRC signaling or MAC Control Element (CE) on a per CORESET per UE or purely per UE basis. Frequency hopping patterns for CORESET transmissions include the use of PRBs for CORESETs that are mirrored with respect to the central frequency of active bandwidth part (BWP), and the use of a random parameter to step through the frequency pattern. The sub-band location of the physical downlink shared channel that is scheduled by the physical downlink control channel may be indicated using the DCI format, or may be based on a last slot for PDCCH transmission.
