Apparatus and method for transmitting data signals in wireless communication system

A method for operating a radio node in a wireless communication system, the method comprising:

• transmitting identification information of a band designated for a terminal;
• and
• transmitting a data signal generated based on resource allocation information on the band and an orthogonal frequency division multiple access (OFDMA) scheme.

An apparatus for a terminal in a wireless communication system, the apparatus comprising:

• a receiving unit configured to receive identification information of a band designated for the terminal, and receive a data signal generated based on resource allocation information on the band and an orthogonal frequency division multiple access (OFDMA) scheme;
• and
• a controller configured to demodulate and decode the data signal based on the resource allocation information.
