Method of multiplexing multiple access region

A method of multiplexing one or more multiple access regions in a wireless access system, the method comprising:

• multiplexing the one or more multiple access regions so that a first base station and a second base station use a same multiple access scheme in a predetermined resource region allocated to each of the first base station and the second base station, wherein the first base station and the second base station are among a plurality of a base stations which collectively and concurrently use a plurality of different multiple access schemes under a multi-cell environment;
• and
• transmitting multiplexing information acquired when multiplexing the one or more multiple access regions to a mobile station included in a cell region of the plurality of base stations,
• wherein the one or more multiple access schemes include a single carrier frequency division multiple access (SC-FDMA) scheme and an orthogonal frequency division multiple access (OFDMA) scheme, and
• wherein the multiplexing the one or more multiple access regions includes distributing the one or more multiple access regions in accordance with the SC-FDMA scheme and the OFDMA scheme, and
• wherein the predetermined resource region is one of a plurality of resource regions divided according to frequency band.
