Abstract:
1. A base station, comprising: circuitry configured to communicate with a mobile terminal via a relay link between the base station and a relay device and an access link between the relay device and the mobile terminal by orthogonal frequency-division multiplexing, and select a predetermined allocation pattern of an uplink of the relay link, a downlink of the relay link, an uplink of the access link, and a downlink of the access link to frequency-time blocks from a plurality of predetermined allocation patterns, the plurality of predetermined allocation patterns including more than four predetermined allocation patterns, wherein information that indicates said selected predetermined allocation pattern is transmitted from said base station to said relay device, and the plurality of predetermined allocation patterns includes at least two types of predetermined allocation patterns: a first type of predetermined allocation pattern where frequency-time blocks of the downlink of the relay link and the downlink of the access link are different in time, and frequency-time blocks of the uplink of the access link and the uplink of the relay link are different in time domain, and a second type of predetermined allocation pattern where frequency-time blocks of the downlink of the relay link and the downlink of the access link are different in frequency, and frequency-time blocks of the uplink of the access link and the uplink of the relay link are different in frequency domain.
