  • Patent number: 12574782
    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: 12414006
    Abstract: Systems and methods provide flow control for uplink traffic in an integrated access and backhaul network. A first relay node determines that its uplink buffer has reached an occupancy level higher than a pre-determined level. In response, the first relay node transmits, to a second relay node associated with the first relay node, a message indicating a buffer occupancy status of the uplink buffer of the first relay node.

  • Patent number: 12262262
    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.

    Abstract: Techniques to configure a UE for time-division multiplexing (TDM)-based 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 indicates the UE supports the TDM-based 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 from the SBS is decoded, which includes a handover command in response to the measurement report. The handover command indicates a TDM pattern for multi-connectivity with the SBS and the TBS during the handover. UL data is encoded for transmission to the SBS. Transmission of the UL data to the SBS is time-division multiplexed with communications between the UE and the TBS during the handover based on the TDM pattern.
