    Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for configuring the operation of a use equipment (UE) for and after exiting a conditional handover. Some embodiments are directed to a user equipment (UE). The UE includes processor circuitry and radio front circuitry. The processor circuitry can be configured to receive, using the radio front end circuitry and from a source device associated with a source cell, a conditional handover command for a conditional handover to a target cell. The processor circuitry can be further configured to determine, based on the received conditional handover command, a condition for exiting the conditional handover. The processor circuitry can be further configured to in response to the condition being met, exit the conditional handover.

    Abstract: Techniques to configure a user equipment (UE) for radio link failure (RLF) handling during a multi-connectivity handover with a source base station (SBS) and a target base station (TBS) include encoding a measurement report for transmission to the SBS via a first communication link. The measurement report is triggered based on a measurement event configured by the SBS. RRC signaling is received from the SBS, the RRC signaling including a handover command in response to the measurement report. The handover command includes an indication for multi-connectivity support by the SBS and the TBS during the handover. A random access channel (RACH) procedure with the TBS is performed using a second communication link between the UE and the TBS. Radio link monitoring (RLM) on the first communication link and the second communication link is performed during the handover.

    Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for performing multiple signal quality measurements in a 5G network, the processing circuitry is to encode configuration signaling for transmission to a base station. The configuration signaling indicates the UE supports multiple measurement gap (MG) patterns in parallel. RRC signaling responsive to the configuration signaling is decoded. The RRC signaling comprising configuration information to configure the UE for multiple measurement gaps in parallel and provides SMTC for synchronization signal transmissions within the multiple measurement gaps. A plurality of SSBs is decoded using periodicity and duration information of the synchronization signal transmissions included in the SMTC, the plurality of SSBs received during the multiple measurement gaps. Multiple signal quality measurements are encoded for transmission to the base station, the multiple signal quality measurements based on the plurality of SSBs.

    Abstract: Devices, methods, user equipment (UE), core network devices, base stations, and storage media are provided for per-component carrier (CC) and network controlled small gap (ncsg) measurement gap configuration. In one embodiment, processing circuitry of a UE decodes an RRCConnectionReconfiguration communication from a base station, the RRCConnectionReconfiguration communication comprising a measure gap configuration (MeasGapConfig) information element, the MeasGapConfig information element comprising a gap offset field (gapOffset) indicating one or more gap offset gap patterns, the one or more gap offset gap patterns (gp) comprising at least a first network-controlled small-gap (ncsg) gap pattern (gp-ncsg). Information from this communication is used to set up a measurement gap configuration indicated by the MeasGapConfig information element in accordance with the gapOffset. Other embodiments involve other information for various combinations of per-CC and ncsg gap configurations.
