摘要： 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.

摘要： A method and apparatus for allocating resources of a Visible Light Communication (VLC) terminal in a VLC system. The VLC terminal receives a beacon message from a base station, coordinates time synchronization with the base station, searches for an available wavelength channel, constructs available wavelength channel information, and transmits an initial access request using a basic time slot channel and a basic wavelength channel. The base station considers the available wavelength channel information and a current channel allocation condition, allocates an appropriate channel, and transmits channel allocation information to the VLC terminal. The VLC terminal and the base station communicate data with each other using an allocated time slot channel included in the channel allocation information and an allocated wavelength channel included in the channel allocation information.
