  • Patent number: 12224902
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit assistance information to a base station to request an update or a modification to one or more communication parameters configured at the UE. Such communication parameters may include a quantity of uplink multiple-input multiple-output (MIMO) layers, a quantity of downlink MIMO layers, a minimum scheduling offset, a maximum quantity of component carriers, or a maximum aggregated bandwidth for a secondary cell group (SCG). In some implementations, the UE may transmit the assistance information requesting the update or modification to one or more of such communication parameters based on detecting that the UE satisfies one or more triggering conditions or thresholds.

  • Publication number: 20250048203
    Abstract: The UE may store target cell information to a database based on performing a handover to the target cell and detecting the ping-pong handover based on a number of handover instances in the database of the target cell to which the UE has performed the handover being greater than or equal to a threshold number of the handover instances within a period of time. The UE may receive, from a base station a list of ping-pong cell candidates and configure the number of handover instances of the target cell and/or the period of time based on the list of ping-pong cell candidates. The UE may avoid or reduce the handover to the identified ping-pong cell based on the detected ping-pong handover by applying an offset to the measurement of the target cell.
