Claim Text:
1. A method for a first type base station to allocate a resource in a wireless communication system including the first and second types base stations, the method comprising: identifying a first frequency assignment (FA) allocated to a neighbor second type terminal based on an uplink transmission signal transmitted from the neighbor second type terminal to a second type base station; determining an available FA based on the first FA, the available FA being not overlapped with the first FA; allocating sub-channels associated with one of available FAs not used by the neighbor second type terminal to a first type terminal; and allocating, if there does not exist any available FA not used by the neighbor second type terminal, the sub-channels associated with an FA, for which a sum of energies of sub-channels is minimum, to the first type terminal, wherein a sub-channel for downlink transmissions of the neighbor second type terminal are allocated in the first FA in which a sub-channel for uplink transmissions of the neighbor second type terminal are allocated, to determine the available FA, if the neighbor second type terminal is located at the first type base station interference area.
