    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.

    Abstract: Systems and methods for using clear channel assessment (CCA) on a channel prior to transmitting the channel are disclosed. A wireless transmission system may perform omnidirectional CCA using a CCA power threshold that is calculated based on a number of synchronization signal blocks (SSBs) transmitted by the wireless transmission system per SSB burst or per synchronization signal/physical broadcast channel (SS/PBCH) block measurement timing configuration (SMTC) window, or on a number of transmit (Tx) antennas used. A wireless transmission system may perform directional CCA on one or more Rx beams that correspond to one or more intended Tx beams using CCA power thresholds calculated based on an equivalent isotropic radiated power (EIRP) of the one or more intended Tx beams to determine directional availability of the channel. A wireless transmission system may determine a CCA power threshold based on a scaling between an actual CCA bandwidth and a nominal CCA bandwidth.

    Abstract: A user equipment (UE) is connected to a 5G New Radio (NR) network via a serving cell. The UE performs radio resource management (RRM) measurements on the serving cell, determines whether the UE satisfies power saving criteria for a first, second, or third mobility scenario while in a Radio Resource Control (RRC) idle state or RRC inactive state, wherein, when the UE is in the first or second mobility scenario, the UE performs RRM measurements with longer intervals relative to RRM measurements performed in a non-power-saving mode and wherein, when the UE is in the third scenario, the UE performs RRM measurements for neighbor cells with longer intervals relative to RRM measurements performed in a non-power-saving mode and determines a UE RRM configuration when the UE transitions from any of the power saving scenarios or the non-power-saving mode to any other power saving scenarios or the non-power-saving mode.
