Abstract

A base station including an allocation unit for allocating the downlink of the relay link or the access link and the downlink of the direct link to a resource block included in a same resource block group, and allocating the uplink of the relay link or the access link and the uplink of the direct link to a resource block included in a same resource block group.

Claims

1. A base station comprising:

a communication interface 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; and

circuitry configured to

allocate a resource block included in a first resource block group to a downlink of the relay link;

allocate a resource block included in a second resource block group to a downlink of the access link;

allocate a resource block included in a third resource block group to an uplink of the access link; and

allocate a resource block included in a fourth resource block group to an uplink of the relay link, wherein

the first resource block group is same in frequency but different in time from the second resource block group, and is same in time but different in frequency from the third resource block group, and

the fourth resource block group is same in time but different in frequency from the second resource block group, and is same in frequency but different in time from the third resource block group.

2. A base station comprising:

a communication interface 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; and

circuitry configured to

allocate a resource block included in a first resource block group to a downlink of the relay link;

allocate a resource block included in a second resource block group to a downlink of the access link;

allocate a resource block included in a third resource block group to an uplink of the access link; and

allocate a resource block included in a fourth resource block group to an uplink of the relay link, wherein

the first resource block group is same in frequency but different in time from the second resource block group, and is same in time but different in frequency from the fourth resource block group, and

the third resource block group is same in time but different in frequency from the second resource block group, and is same in frequency but different in time from the fourth resource block group.

3. A base station comprising:

a communication interface 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; and

circuitry configured to

allocate a resource block included in a first resource block group to a downlink of the relay link;

allocate a resource block included in a second resource block group to a downlink of the access link;

allocate a resource block included in a third resource block group to an uplink of the access link; and

allocate a resource block included in a fourth resource block group to an uplink of the relay link, wherein

the first resource block group is same in frequency but different in time from the fourth resource block group, and is same in time but different in frequency from the third resource block group, and

the second resource block group is same in time but different in frequency from the fourth resource block group, and is same in frequency but different in time from the third resource block group.

4. A base station comprising:

a communication interface 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; and

circuitry configured to

allocate a resource block included in a first resource block group to a downlink of the relay link;

allocate a resource block included in a second resource block group to a downlink of the access link;

allocate a resource block included in a third resource block group to an uplink of the access link; and

allocate a resource block included in a fourth resource block group to an uplink of the relay link, wherein

the first resource block group is same in frequency but different in time from the third resource block group, and is same in time but different in frequency from the fourth resource block group, and

the second resource block group is same in time but different in frequency from the third resource block group, and is same in frequency but different in time from the fourth resource block group.

5. A base station comprising:

a communication interface 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; and

circuitry configured to

allocate a resource block included in a first resource block group to a downlink of the relay link;

allocate a resource block included in a second resource block group to a downlink of the access link;

allocate a resource block included in a third resource block group to an uplink of the access link; and

allocate a resource block included in a fourth resource block group to an uplink of the relay link, wherein

the first resource block group is same in frequency but different in time from the third resource block group, and is same in time but different in frequency from the second resource block group, and

the fourth resource block group is same in time but different in frequency from the third resource block group, and is same in frequency but different in time from the second resource block group.

6. A base station comprising:

a communication interface 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; and

circuitry configured to

allocate a resource block included in a first resource block group to a downlink of the relay link;

allocate a resource block included in a second resource block group to a downlink of the access link;

allocate a resource block included in a third resource block group to an uplink of the access link; and

allocate a resource block included in a fourth resource block group to an uplink of the relay link, wherein

the first resource block group is same in frequency but different in time from the fourth resource block group, and is same in time but different in frequency from the second resource block group, and

the third resource block group is same in time but different in frequency from the fourth resource block group, and is same in frequency but different in time from the second resource block group.

7. A base station comprising:

a communication interface 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; and

circuitry configured to

allocate a resource block included in a first resource block group to a downlink of the relay link;

allocate a resource block included in a second resource block group to a downlink of the access link;
