A wireless communication method for a plurality of terminals in a wireless communication system, wherein: the wireless communication system uses a frame comprising a plurality of sub-frames being units of a transmission, the sub-frames comprising a plurality of data symbols and guard intervals of a same length between the data symbols, each sub-frame being transmitted every frame period, and one of two types of guard interval lengths being assigned to each sub-frame; the method comprising: receiving placement information which indicates timings of guard intervals of a short and a long guard interval lengths applied in sub-frames for transmitting dedicated data and for small to medium cells and for transmitting broadcast/multicast data and for large cells, respectively, in the frame to which a specified sub-frame belongs, where the placement information is multiplexed to a transmission signal in the specified sub-frame and guard intervals of a fixed first guard interval length are inserted between the data symbols in the specified sub-frame; determining the short and the long guard interval lengths applied in the sub-frames in the frame, based on the placement information; and removing a guard interval of the short and the long guard interval lengths from a reception signal, based on the placement information. the wireless communication system uses a frame comprising a plurality of sub-frames being units of a transmission, the sub-frames comprising a plurality of data symbols and guard intervals of a same length between the data symbols, each sub-frame being transmitted every frame period, and one of two types of guard interval lengths being assigned to each sub-frame; the method comprising: receiving placement information which indicates timings of guard intervals of a short and a long guard interval lengths applied in sub-frames for transmitting dedicated data and for small to medium cells and for transmitting broadcast/multicast data and for large cells, respectively, in the frame to which a specified sub-frame belongs, where the placement information is multiplexed to a transmission signal in the specified sub-frame and guard intervals of a fixed first guard interval length are inserted between the data symbols in the specified sub-frame; determining the short and the long guard interval lengths applied in the sub-frames in the frame, based on the placement information; and removing a guard interval of the short and the long guard interval lengths from a reception signal, based on the placement information. receiving placement information which indicates timings of guard intervals of a short and a long guard interval lengths applied in sub-frames for transmitting dedicated data and for small to medium cells and for transmitting broadcast/multicast data and for large cells, respectively, in the frame to which a specified sub-frame belongs, where the placement information is multiplexed to a transmission signal in the specified sub-frame and guard intervals of a fixed first guard interval length are inserted between the data symbols in the specified sub-frame; determining the short and the long guard interval lengths applied in the sub-frames in the frame, based on the placement information; and removing a guard interval of the short and the long guard interval lengths from a reception signal, based on the placement information.
