A method for a base station to allocate resources for supporting a plurality of wireless communication modes in a wireless system according to the present invention comprises the steps of: allocating, using frequency-division multiplexing, a first zone composed of orthogonal frequency division multiplexing (OFDM) symbols and a second zone composed of generalized frequency division multiplexing (GFDM) symbols on time and frequency domains; and allocating a predetermined number of guard subcarriers to the boundary between the first zone and the second zone, wherein the predetermined number is determined on the basis of the number of sub-symbols of the GFDM symbols of the second zone.
