Abstract:
A method for transmitting control information by a base station in a communication system using a plurality of serving cells comprises transmitting is provided. The method includes a terminal, an identifier of a second serving cell identifying where control information regarding a first serving cell is transmitted, transmitting, to the terminal, a predetermined value of a carrier identifier used in the second serving cell, and transmitting the control information regarding the first serving cell including the carrier identifier having the predetermined value through the second serving cell.
Abstract:
A method and apparatus for generating a visible signal to enable a user to confirm the amount of data transmission in Visible Light Communication (VLC) are provided. The apparatus previously acquires amount information of data which is to transmit or receive, and acquires the ratio of the amount of data transmitted to a receiving-side VLC device from a transmitting VLC device or the amount of data transmitted from the transmitting-side VLC device received by the receiving VLC device to the total amount of data. The apparatus determines a visible light output pattern corresponding to the data ratio and generates visible light of the determined output pattern.
Abstract:
A method for aligning among visible light communication devices comprises the following steps: generating a visible light signal and transmitting same to a corresponding device; determining whether the visible light signal that is output via the screen of the device is identifiable; correcting the color of the visible light signal that is output on the screen if the visible light signal is not identifiable; and using the visible light signal that is corrected to perform alignment for visible light communicating with the corresponding device.

Abstract:
A wireless charging apparatus and method are provided. The method includes transmitting a power supplying device search signal by a wireless power receiving device; recognizing a plurality of power supplying devices by receiving power supplying device search response signals; sending a power supply request to a first power supplying device among the plurality of power supplying devices; sending a power supply request to a second power supplying device upon receiving a charging rejection signal from the first power supplying device; and performing wireless charging by receiving power from the second power supplying device upon receiving a charging permission signal from the second power supplying device.
Abstract:
An apparatus for transmitting information using a visible light includes at leastthree light emitting devices, each being installed based on a predetermined interval and direction, and a data transmitting unit to transmit data by controlling the at least three light emitting devices.
