Abstract
A visible light communication method and terminal are provided for communicating with a visible light coordinator which discriminates between at least one communication area cell that includes at least one light source and a boundary area positioned between the communication area cell and another communication area cell adjacent to the communication cell area, and which provides time division visible light communication. Data of the visible light communication terminal is received from the visible light coordinator using a first time slot in a first communication area cell determined according to a position of the visible light communication terminal. The visible light coordinator is communicated with using a second time slot assigned from the visible light coordinator, when the visible light communication terminal is located in a boundary area of the first communication area cell. The second time slot has not been assigned to the visible light communication terminal.
