Abstract: Disclosed are a method and an apparatus to control a media access control (MAC) layer protocol for device-to-device communications although an identifier (ID) of a target terminal is unknown. The apparatus to control the MAC protocol provided in the present invention comprises: a target terminal determining part selecting primary target terminals using relative distance information of the target terminal intended to be communicated from a main terminal, and determining a final target terminal using relative distance information between the main terminal and the primary target terminals; a transmitting part transmitting a selection alarm message and a relative distance information request message generated by the target terminal determining part to the primary target terminals; and a receiving part receiving a response message to the selection alarm message and the relative distance information to determine the final target terminal from the primary target terminals.

Abstract: The present invention applies a relatively low voltage to a semiconductor photo detector and provides a silicon-substrate-based Ge semiconductor photo detector which has high gain, increase receiving sensitivity, high speed characteristic. A Ge based amplification layer, that is a single Ge layer or Ge/Si supper lattice layer is formed on the silicon substrate. A Ge charge layer is formed on it. A Ge light absorption layer is formed on the charge layer. A polysilicon second contact layer is formed on the light absorption layer. Also, the light absorption layer may be formed as a Ga quantum dot/ quantum line layer.

Abstract: PURPOSE: A device recognition apparatus and a method thereof are provided to reduce time to spend on selecting a device to set up a communication link. CONSTITUTION: A wireless unit (110) produces a main beam and side beams. A transmitting signal processing unit (120) directs the wireless unit to control the direction of the main beam which is to be toward a peripheral in order to set up a communication link. A receiving signal processing unit (130) receives an intensity of each signal corresponding to the main beam and each side beam from each peripheral. A control unit (140) calculates signal differences among the main beam and each side beam based on the intensities of the receiving signals. The control unit selects a peripheral among a plurality of the peripherals in order to set up a communication link based on the calculation.
