Abstract: Disclosed are a method and apparatus for connecting a terminal and a base station in a multi-hop network. A method of a terminal may comprise: receiving cell selection and reselection criteria information broadcast from a base station; determining candidate base stations among all base stations capable of communicating with the terminal based on the cell selection and reselection criteria information; selecting one connection scheme from a lightening backhaul load (LBL) scheme or a maximum reference signal received power (RSRP) scheme based on a tolerable gap, which is a parameter for determining the candidate base station; selecting one candidate base station from among the candidate base stations as a target base station based on the one connection scheme; and connecting to the target base station.

Abstract: Provided is a high voltage driving device including a housing and a cathode, an anode, and an insulation structure, which are disposed in the housing. Here, the cathode and the anode are spaced apart from each other with the insulation structure therebetween. Also, the insulation structure includes a first solid insulator disposed adjacent to the cathode and a second solid insulator disposed adjacent to the anode. Also, the first solid insulator has first volumetric resistivity less than second volumetric resistivity of the second solid insulator, and the first solid insulator contacts the cathode.
