<p>A frame flexible to a different mode and TDD(Time Division Duplication)/FDD(Frequency Division Duplication) support, and a signal transmission method using the same are provided to smoothly move to single mode frame configuration as well as supporting the different mode. A signal is formed by a frame unit and is transmitted. When a communication system performs communication in a TDD mode, a ratio between a downlink area and an uplink area in a frame is determined. When the communication system performs the communication in a different mode supporting more than two communication modes, a time section of each communication mode is allocated in the frame. A mode for forming a sub frame in the frame with the frame or super frame units is determined.</p> |
