<P>PROBLEM TO BE SOLVED: To appropriately solve the problem of interference of an adjacent cell in introduction of relay techniques while applying an inter-cell interference coordination. <P>SOLUTION: By deciding positions of frequencies used via a relay station by a system in advance for assignment of boundary frequencies, frequencies of a central frequency more likely to be affected by the relay station are also mapped by avoiding a signal thereof. Alternatively, an adjacent cell whose central frequency is affected changes depending on a position of the relay station and thus, locations set to be highly likely to interfere with the central frequency of the adjacent cell are reduced by setting a region of the boundary frequencies permitted to the relay station in accordance with the position of the relay station. <P>COPYRIGHT: (C)2011,JPO&INPIT |
