  • Transmission power control method and device for cognitive radio device
    Patent number: 9215661
    Abstract: A method and an apparatus for controlling transmit power of a CR device are provided. The method includes acquiring CR environment information regarding a licensed user or an unlicensed user occupying an adjacent channel or an adjacent cell of the CR device; determining a transmit power value of the CR device using the CR environment information; and generating transmit power control information including the transmit power value. The method and apparatus guarantee reliable communication of the CR device and minimize interference with the licensed user.
    Type: Grant

  • PORTABLE VIDEO COMMUNICATION DEVICE HAVING CAMERA, AND METHOD OF PERFORMING VIDEO COMMUNICATION USING THE SAME
    Publication number: 20130278729
    Abstract: A video communication device includes a first camera and a second camera that are positioned at different positions to form a symmetrical relationship about a reference point at a periphery of a video display screen. The video communication device performs video communication based on images that are acquired from the first camera and the second camera, and performs a communication mode change according to a request for a communication mode change.
