Abstract:
The method for transmitting a signal of an orthogonal frequency division multiplexing type according to an exemplary embodiment of the present invention has a configuration allowing a radio unit (RU) to perform a component adding a compression component and a decompression component before/after a serial interface interlocking between a digital unit (DU) and the radio unit (RU) and a component inserting a cyclic prefix (CP) into a signal so as to secure orthogonality of an orthogonal frequency division multiplexing (OFDM) signal, in a structure in which a base station is physically divided into the DU and the RU.
