Abstract: An apparatus of a user equipment (UE) includes processing circuitry, where to configure the UE for conditional handover between a source base station (SBS) and a target base station (TBS) in a wireless network, the processing circuitry is to decode measurement configuration information from the SBS. The measurement configuration information indicating a measurement event and a first threshold associated with the measurement event to trigger measurement reporting. A measurement report is encoded for transmission to the SBS, the measurement report triggered based on the first threshold. RRC signaling is received from the SBS. The RRC signaling includes a conditional handover command indicating a second threshold for the measurement event, the second threshold being higher than the first threshold. A handover from the SBS to the TBS is performed based on the conditional handover command after detecting that the measurement event satisfies the second threshold.

Abstract: A user equipment (UE) may assess a radio link quality of a plurality of frames for communication, via the interface to the RF circuitry, with a radio access network (RAN) node. When the radio link quality of a frame, of the plurality of frames, is below an out-of-sync (OOS) threshold, the UE may indicate that the frame is OOS. When the radio link quality of a frame, of the plurality of frames, is above an in-sync (IS) threshold that the frame is IS. Additionally, or alternatively, the UE may process information, received from the RAN node indicating a partial subframe, of a subframe, to be used to transmit uplink control information (UCI) to the RAN node. The UE ma also perform UCI mapping for using of the partial subframe to transmit UCI via a physical uplink control channel (PUSCH), and proceed by using the partial subframe to communicate the UCI to the RAN node.

Abstract: Beamforming measurement techniques based on PSS/SSS are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode a configuration message from a source serving cell, the configuration message indicating signal selection criteria for cell measurement reporting. A synchronization signal (SS) burst set associated with one or more transmission/reception points (TRPs) within a neighboring cell is decoded, the SS burst set including a plurality of SS blocks. A cell beamforming measurement signal associated with the neighboring cell is generated, based on signal measurements of the SS blocks and the signal selection criteria. A radio resource management (RRM) measurement report message is encoded for transmission to the serving cell, the measurement report message including the cell beamforming measurement signal. A handover command message for initiating a handover to the neighboring cell is decoded, the handover command based on the cell beamforming measurement signal.

Abstract: An apparatus of a user equipment (UE) can include processing circuitry configured to encode capability information for transmission within a serving cell of an evolved Node-B (eNB), the capability information indicating the UE supports per UE network controlled small gap (NCSG) operation. A request message is encoded to request a per UE NCSG on a first frequency associated with the serving cell. Configuration information received in response to the request message can be decoded, the configuration information including a NCSG configuration for the NCSG on the first frequency. Measurements can be performed on a second frequency during a measurement gap, the measurement gap configured based on the NCSG configuration. A network message is decoded in response to the capability information, the network message including an indication of the request message for requesting the per UE NCSG on the first frequency.
