1. A method of operating user equipment (UE) in a wireless communications network, the method comprising:

  • identifying, by the UE, a target cell type associated with a neighboring cell;

    in response to identifying the target cell type associated with the neighboring cell, determining, by the UE, a time-to-trigger parameter, wherein the time-to-trigger parameter is determined by applying a scaling factor associated with the target cell type to a nominal time-to-trigger value, the scaling factor associated with the target cell type is based, at least in part, on a transmission power level of the neighboring cell and a transmission power level of the UE'"'"'s serving cell; and

    executing, by the UE, a mobility procedure with the neighboring cell using the time-to-trigger parameter.
