    摘要: According to one embodiment, a method for repetitive transmission using a plurality of sub-carriers includes: preparing a symbol to be transmitted using the plurality of sub-carriers within a single time domain unit; repeating the symbol a predetermined number (N) of times; applying a corresponding one of N different cyclic shift values to each of the N repeated symbols to be transmitted using the plurality of sub-carriers within the single time domain unit; performing an IFFT (Inverse Fast Fourier Transform) on each of the N repeated symbols to which the corresponding one of the N different cyclic shift values is applied; and transmitting the N repeated symbols on which the IFFT is performed using the plurality of sub-carriers.
