Abstract: Briefly, in accordance with one or more embodiments, user equipment (UE) comprising circuitry to connect to a network via a serving cell; and indicate to the network a measurement gap capability of the UE. The measurement gap capability includes information if the UE supports a carrier aggregation (CA) specific measurement gap and if the UE has two or more radio-frequency (RF) chains. The UE then receives a CA specific measurement gap configuration from the network for the two or more RF chains.

Abstract: Techniques to configure a UE for a multi-connectivity handover with a source base station (SBS) and a target base station (TBS) include encoding UE capability information for transmission to the SBS, the UE capability information indicating tire UE supports multi-connectivity handover. A measurement report is encoded for transmission to the SBS, the measurement report triggered based on a measurement event configured by the SBS. RRC signaling is received from the SBS and includes a handover command for a multi-connectivity handover from the SBS to the TBS. The handover command is in response to the measurement report and the UE capability information. First UL data and second UL data are encoded for transmission during the multi-connectivity handover. The first UL data is encoded for transmission to the SBS and the second UL data is encoded for transmission to the TBS during the multi-connectivity handover.

Abstract: Techniques discussed herein can facilitate configuration by a network of one or more measurement gaps based at least in part on UE (User Equipment) assistance. One example embodiment employable by a UE (User Equipment) comprises a memory interface; and processing circuitry configured to: generate UE capability information that comprises, for each measurement scenario of one or more measurement scenarios, an indication of whether the UE is capable of non-gap measurement in connection with that measurement scenario, wherein each measurement scenario applies to one or more associated serving frequencies and one or more associated measurement objects; and process configuration signaling that comprises, for each measurement scenario of the one or more measurement scenarios, an associated indication of whether an associated measurement gap is configured for that measurement scenario.

Abstract: 5G methods and architectures to determine active SCells and their bandwidth parts (BWP) used in carrier aggregation (CA) are disclosed in which activating a BWP for an active SCell is performed initially according to a default value provided in initial radio resource control (RRC) messaging. After initialization, SCells and the SCell BWPs used by the user equipment (UE) are activated by RRC messaging, downlink control information (DCI) or dedicated medium access control (MAC) control elements (MAC CEs) with the initial BWP used for an activated SCell being a default value provided during initialization.

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 secondary node (SN) in evolved universal mobile telecommunications system terrestrial radio access network new radio-dual connectivity (EN-DC) with a master node (MN) can directly provide measurement configuration and receive measurement reports from a UE and/or coordinate measurement configuration and reporting with the MN. For example, only one measurement object configuration is allowed for a frequency, but both MN and SN can provide measurement reporting configurations on the same measurement object. The UE can send measurement reports for the same measurement object to both MN and SN or the node that configured the reporting criteria configuration. In another embodiment, only one node provides the reporting configuration but configures the UE to provide reporting to one node or both MN and SN.
