    • An apparatus and a method for processing bandwidth request in a multi-hop relay broadband wireless access communication system are provided to enable a relay station to report the number of terminals which transmit bandwidth request ranging code to a base station. A relay station extracts receiving signals from a bandwidth request ranging region(301). The relay station performs code demodulation by correlating the ranging code with the extracted data(303). The relay station judges whether the bandwidth request ranging code is received from the code demodulation result(305). The relay station decides the number of terminals which transmit the bandwidth request ranging code(307). The relay station reports the number of the terminals to the base station through a previously allotted feedback channel(309). The relay station verifies whether a resource allotment message responding to the bandwidth request ranging code is received from the base station(311). The base station writes information concerned with the ranging code within the received resource allotment message(313). The relay station transmits the resource allotment message to the terminal(315).

    • A piezoelectric MEMS(Micro Electric Mechanical system) switch and a manufacturing method for the same are provided to form a piezoelectric actuator firstly before an RF signal line for preventing the excessive etching process of the rear surface of the substrate, and for improving the driving efficiency of the actuator. A piezoelectric MEMS(Micro Electric Mechanical system) switch comprises a substrate(101), first and second fixed signal lines, a piezoelectric actuator(130), and a moving signal line(150). The piezoelectric actuator is placed at the same line as the first and second fixed signal lines. One end of the piezoelectric actuator is supported by the substrate to be longitudinally driven. At least one side of the moving signal line is connected to an upper surface of the piezoelectric actuator. One end of the piezoelectric actuator is connected to at least one of the signal lines, and the other end of the actuator is contacted and separated with or from the signal lines. An interval part of the substrate is formed with a first cavity. A second cavity is formed to one side of the first cavity. The moving signal line has first and second supports(151,153), and a contact part(155).

    • A MEMS(Micro Electro Mechanical Systems) switch is provided to prevent stiction from occurring between contact points by turning the switch on and/or off by using electrostatic and piezoelectric forces. A first contact point(120) is positioned in a predetermined first area on an upper surface of a substrate(110). A support layer(130) is suspended at a predetermined distance from the upper surface of the substrate. A second contact point(140) is formed on a lower surface of the support layer. A first actuator(150) moves the support layer in a predetermined direction by using an electrostatic force. A second actuator(160) moves the support layer in a predetermined direction by using a piezoelectric force. If a predetermined first power source is connected to the first actuator, the first actuator moves the support layer toward the substrate so that the second contact point contacts the first contact point.
