<P>PROBLEM TO BE SOLVED: To prevent interference during relay of a relay station while applying an inter-cell interference coordination. <P>SOLUTION: A base station adaptively selects a relay method for dividing a time slot with time and frequency so that a relay link and an access link of a relay station do not interfere with one another, and an uplink and a downlink do not interfere with each other, based on three items such as whether each of the relay station and a mobile station exists in a center region or a peripheral region, and whether the relay station can perform transmission and reception operations at the same time by being multiplexed in the frequency direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
