  • Publication number: 20250031110
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may compare an external list of ping pong handovers or redirections that is maintained by an access point, and an internal list of ping pong handovers or redirections that is maintained by the UE. The UE may identify a ping pong detection criterion, for a handover or redirection between a first network node and a second network node, based, at least in part, on the external list, the internal list, both the external list and the internal list, or neither of the external list nor the internal list indicating a previous ping pong handover or redirection between the first network node and the second network node. Numerous other aspects are described.

  • Publication number: 20240143970
    Abstract: Some embodiments provide a method of predicting a state of a system that is represented by a partial differential equation. The method comprises training a neural network for an initial state of said system to obtain a set of neural network parameters to provide a spatial representation of said system at an initial time. The method further comprises modifying said parameters for intermediate times between said initial time and a prediction time such that each modified set of parameters is used to provide a respective spatial representation of said system at each corresponding intermediate time using said neural network. The method further comprises modifying said set of parameters to provide a prediction set of parameters that is used to provide a predicted spatial representation of said system at said prediction time using said neural network.

  • Publication number: 20240007910
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station according to a first radio access technology (RAT) in a first frequency range. The UE may perform measurements on a set of candidate cells of a second RAT or a second frequency range based on a determination for the UE to operate according to the second RAT or the second frequency range. The UE may perform a mobility procedure to establish a connection with a first cell of the set of candidate cells based on a determination that a first value of a first measurement parameter for the first cell satisfies a first threshold, and further based on a comparison of a different, second value of a second measurement parameter for the first cell to a second threshold.

  • Publication number: 20230370916
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), a neighbor cell list including entries for at least a first set of neighbor cells and a second set of neighbor cells, the first set of neighbor cells and the second set of neighbor cells associated with a second RAT. The UE may determine that the first set of neighbor cells is associated with a first network operator and that the second set of neighbor cells is associated with a second network operator.

  • Publication number: 20230346644
    Abstract: A medicine bottle for separately containing, preparing, and delivering solid and liquid medicine includes a bottle body, a first sealing separator, a second sealing separator, a sliding penetration rod, and a protective structure. The first sealing separator and the second sealing separator are separately sealed and arranged inside the bottle body to separate a compartment of the bottle body into upper, middle, and lower chambers. The sliding penetration rod is arranged inside the upper chamber of the bottle body as a cylinder in clearance fit with an inner wall of the bottle body, forming piston-like connection allowing for relative sliding. The sliding penetration rod has a through hole inside and a length greater than a sum of lengths of the upper and lower chambers of the bottle body. The protective structure is cup-shaped and fastened upside-down on a top of the bottle body to protect the sliding penetration rod.
