  • Publication number: 20240147288
    Abstract: This disclosure describes systems, methods, and devices related to measurement gaps. A user equipment (UE) device may identify a configuration message, received from a 5G network device prior to switching from an active bandwidth part (BWP), for a pre-configured measurement gap during which the UE device is to perform an both gapless and gap-based frequency measurements, the configuration message indicating that the pre-configured measurement gap requires activation; identify an activation of the pre-configured measurement gap; and measure a reference signal during the pre-configured measurement gap.

  • Patent number: 11950146
    Abstract: Techniques to configure a user equipment (UE) for 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. The measurement report is triggered based on a measurement event configured by the SBS. Radio resource control (RRC) signaling from the SBS is decoded, 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 first protocol stack associated with the SBS and a second protocol stack associated with the TBS are configured at the UE. A packet data convergence protocol (PDCP) protocol data unit (PDU) received at the UE during the handover is processed using the first protocol stack or the second protocol stack.

  • Publication number: 20240098539
    Abstract: In a fifth-generation (5G) new radio (NR) network, a generation node B (gNB) determines parameters for a Network Controlled Small Gap (NCSG) to reduce and/or eliminate interruptions at a user equipment (UE) for use when the UE is transitioning to a new target frequency for measurements or when the UE is switching or transiting between bandwidth parts (BWPs). The NCSG may be configured to align with one or more fundamental parameters of a legacy measurement gap (MG) pattern to reduce the interruptions.

  • Patent number: 11805456
    Abstract: A UE may decode a radio-resource control (RRC) reconfiguration message comprising a conditional handover (CHO) configuration (CHO-Config) which may identify a CHO configuration for at least one target candidate cell. The CHO configuration may include two or more CHO triggering events for an entry condition. The UE may monitor measurement quantities of the target candidate cell for the entry condition to determine if any of the CHO triggering events are met, start a first count-down timer when the entry condition of a first of the CHO triggering events is met and start a second count-down timer when the entry condition of a second of the CHO triggering events is met. The UE may apply the CHO configuration to the target candidate cell when both of the two CHO triggering events remain fulfilled upon expiration of the both timers.
