摘要： 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 is reduced by setting a region of the boundary frequencies permitted to the relay station in accordance with the position of the relay station.

摘要： A relay node (or relay station) operates as an intermediary entity in a transmission between a base station and a mobile station based on its position in a cell and the mobile station's position in the cell. Since the cell is divided into multiple regions and different wireless resources are used in the multiple regions, the relay node employs the relevant wireless resources to be used in the communications based on positions of the relay node and the mobile station. When the relay station and the mobile station are both in the boundary region, it is possible to avoid interference in the relay station by adapting a relay mode that uses a boundary frequency avoiding interference with adjacent cells for both an uplink and a downlink and demultiplexes a relay link and an access link in a time direction for each of the uplink and the downlink Similar adaptations are made when the mobile station and the relay station are in various positions within a center cell region and boundary cell region.
