Patent ID: 8498662

Claim:
A method to generate power control information in a base station, the method comprising: receiving subcarrier information on subcarriers allocated to a plurality of first terminals that belong to an adjacent base station from the adjacent base station; generating power control information for estimating whether an overlap occurs between the subcarriers allocated to the plurality of first terminals and subcarriers allocated to a second terminal that belongs to the base station, based on the subcarrier information, wherein generating the power control information comprises generating the power control information as a ratio calculated by one of: a total number of subcarriers allocated to the plurality of first terminals divided by a total number of subcarriers that can be used by the base station; a number of subcarriers allocated to the plurality of first terminals that are in common with subcarriers allocated to the second terminal divided by a total number of subcarriers allocated to the second terminal; or a number of subcarriers allocated to the plurality of first terminals that are in common with allocated subcarriers of the base station divided by a total number of the allocated subcarriers of the base station; and transmitting the power control information to a second terminal that belongs to the base station.
