  • Patent number: 11350400
    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.

  • Publication number: 20220124529
    Abstract: Embodiments of a Next Generation Node-B (gNB), User Equipment (UE) and methods of communication are generally described herein. A Master gNB (MgNB) may be arranged to operate in accordance with a New Radio (NR)-NR Dual Connectivity (NR-NR DC) arrangement with a Secondary gNB (SgNB). If the UE does not support per-frequency (per-FR) measurement gaps, the MgNB may configure a per-UE measurement gap for the UE for measurement of signals in a first frequency range and in a second frequency range. If the UE supports the per-FR measurement gaps, the MgNB may configure a first measurement gap in the first frequency range, and the SgNB may configure a second measurement gap in the second frequency range.

    Abstract: Embodiments of a generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may receive, from the UE, a first measurement report that indicates a first signal quality measurement based on new radio synchronization signals (NR-SS). The gNB may determine, based on reception of the first measurement report, a transmission direction for transmission of channel state information reference signals (CSI-RS) for a second RRM measurement at the UE based on the CSI-RS. The gNB may receive, from the UE, a second measurement report that indicates a second signal quality measurement based on the CSI-RS. The gNB may determine, based at least partly on the first and second signal quality measurements, whether to initiate a handover of the UE from a serving cell to a neighbor cell.
