  • Publication number: 20160234789
    Abstract: Disclosed are a method and an apparatus for controlling distributed transmission power in device-to-device (D2D) communication. The D2D devices individually control their transmission power for the D2D communication link. In addition, a first terminal calculates the transmission power based on the measured channel gain and interference-plus-noise level. The first terminal determines optimal transmission power based on the calculated transmission power by the first terminal, and transmits a transmission power change message including the optimal transmission power to a second terminal. Next, the second terminal transmits a D2D signal based on the optimal transmission power.

  • Patent number: 9118568
    Abstract: The present invention relates to a automotive partial networking apparatus and method, which operate or terminate only a specific electronic control unit corresponding to a service currently being provided in a vehicle network composed of a plurality of electronic control units. In the automotive partial networking method, a automotive partial networking apparatus receives a partial networking-only Controller Area Network (CAN) frame from outside of the apparatus. A partial network table is searched based on the CAN frame, and then a CAN identification (ID) is searched for. A partial networking-only CAN frame is generated using the CAN ID. Partial networking is performed by transferring the generated partial networking-only CAN frame to at least one electronic control unit corresponding to a vehicle service.
