A method for transmitting a signal using a preset frame structure in a communication system which supports a TDD mode and an FDD mode and supports two or more different communication schemes includes constructing a signal in units of the frames and transmitting the signal, wherein at least one of determination of a ratio of a DL region and a UL region within the frame when the communication system communicates according to the TDD mode allocation of a time region according to the modes of the communication schemes when the communication system communicates according to a heterogeneous mode supporting the two or more communication schemes and setting of a construction scheme of sub-frames within the frame in units of a prescribed number of the frames or super-frames, is performed on the basis of a specific unit comprised of n OFDM symbols corresponding to a multiple of a UL subchannelization unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frame for flexibly supporting heterogeneous modes and TDD/FDD modes, and method for transmitting signals using the same","description":"A frame structure for flexibly supporting heterogeneous modes and TDD/FDD modes and a method for transmitting signals using the same are disclosed.
