    Abstract: Some aspects include an apparatus, method, and computer program product for beamforming to perform received signal strength indicator (RSSI) measurements in a 5G wireless communications system. This beamforming may apply to RSSI measurements in an unlicensed spectrum. In some aspects, user equipment (UE) may use beam sweeping to analyze multiple received beams and to determine an RSSI measurement. When using beam sweeping, network nodes may use scheduling and/or measurement restrictions to avoid data collisions. These restrictions may apply to multiple active serving cells. In some aspects, a UE may use beam selection to determine an RSSI measurement. For example, the UE may select one or more beams from a serving component carrier (CC). In some aspects, a network node may indicate to the UE which beams to use for the RSSI measurement. In some aspects, the UE may use a frequency domain resource to perform the RSSI measurement.

    Abstract: Apparatuses, systems, and methods for hybrid measurement gap operation. A network-side device may provide a hybrid measurement gap (MG) configuration to a wireless device, the hybrid measurement gap (MG) configuration scheduling measurement operation of the wireless device in accordance with hybrid measurement gap patterns. The wireless device may receive the hybrid measurement gap (MG) configuration, and thus perform measurement operation based on the hybrid measurement gap patterns as scheduled.

    Abstract: A user equipment (UE) is configured to change a transmission configuration indicator (TCI) state. The receives, from the base station, a network flag indicating a transmission configuration indicator (TCI) state change configuration for the network, determines a time span for continuing to use a current TCI state prior to switching to a new TCI state based on the network flag and switches to the new TCI state after the time span.

    Abstract: Apparatuses, systems, and methods for enhancement in NTN mobility. A cellular base station may serve as a source base station of a handover procedure from the source base station to a target non-terrestrial network (NTN) base station. The cellular base station may configure a parameter associated with the target NTN base station in a handover command, the parameter being related to NTN mobility, and send the handover command to a wireless device for use by the wireless device during the handover procedure. The wireless device may receive the handover command from the cellular base station, and perform the handover procedure using the parameter associated with the target NTN base station.

    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: 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.
