  • Patent number: 10772018
    Abstract: To configure a UE for handover between a source evolved Node-B (eNB) and a target eNB using aerial communications in a cellular network, the UE processing circuitry is to decode measurement configuration information from the source eNB. The measurement configuration information includes a plurality of height thresholds associated with aerial height of the UE. A measurement report is encoded for transmission to the source eNB. The measurement report includes the aerial height of the UE and the measurement report generation triggered based on one or more triggering events associated with the plurality of height thresholds. RRC signaling from the source eNB is decoded, the RRC signaling including a handover command. The handover command is based on a handover decision by the source eNB using the measurement report. A handover from the source eNB to the target eNB is performed based on the handover command.

  • Patent number: 10749587
    Abstract: A new radio (NR) capable user equipment (UE) to determine whether to skip cellular measurements using s-Measure configuration based on measurements of a synchronization signal (SS) block (SSB) and/or Channel State Information Reference Signal (CSI-RS) using an s-Measure configuration. For example, an s-Measure configuration can include a reference signal received power (RSRP) value and an indicator whether to apply the value to an NR SS block or a CSI-RS. If the value meets or exceeds the measurement for the indicated signal measurement, the s-Measure is satisfied. For example, in an embodiment, the network configures a single s-Measure configuration (e.g., either an NR SS s-Measure configuration or a CSI-RS s-Measure configuration), which when satisfied the UE does not perform further measurements.
