WIRELESS RELAY STATION DEVICE, WIRELESS BASE STATION DEVICE, AND RELAY FREQUENCY ALLOCATION METHOD

摘要

In order to increase throughput in an access link and to optimally control wireless link capacity in a backhaul link in a wireless communication system using relay transmission technology, the disclosed relay frequency allocation method has: a step for determining whether or not to apply carrier aggregation in a backhaul link from a wireless base station device to a mobile terminal device under the aforementioned wireless base station device, and/or an access link from a wireless relay station device to a mobile terminal device under the aforementioned wireless relay station device; a step for allocating a frequency band that transmits a downlink signal in the aforementioned backhaul link and/or the aforementioned access link when applying carrier aggregation; and a step for transmitting the downlink signal in the aforementioned backhaul link and/or the aforementioned access link using the allocated frequency band.
