  • Patent number: 11991572
    Abstract: Methods and apparatus are provided for UE-triggered handover and early preparation with coexistence of the network-triggered handover. In one novel aspect, the UE is configured early measurement report configuration, receives an early handover command from the serving base station with a handover candidate cell list, monitors handover triggering conditions for each candidate cell on the handover candidate cell list based on a UE-triggered handover configuration and performs the UE-triggered handover to a candidate cell when the corresponding triggering condition is met for the candidate cell. In one embodiment, the UE receives a network-triggered handover command to a target cell, suspends the UE-triggered handover configuration and performs the network-triggered handover to the target cell. The UE discards the UE-triggered handover configuration upon success of the network-triggered handover and resumes the UE-triggered handover configuration upon failure of the network-triggered handover.

  • Patent number: 11148519
    Abstract: A vehicle chassis including a vehicle frame defining an inner space and being operable to switch between a first expanded state and a collapsed state, and a loading device mounted to the inner space and removably connected to the vehicle frame. The loading device defines a first loading surface when the vehicle frame is in the first expanded state, and the loading device defines a second loading surface that is smaller than the first loading surface when the vehicle frame is in the collapsed state.
