Base station, relay station, and method

A resource assigning method performed at a base station connected to a relay station that relays wireless signals from a mobile station, the resource assigning method comprising:

• generating first resource block assignment information of a first wireless section between the base station and the relay station based on a first propagation quality of the first wireless section;
• calculating a ratio between a number of first resource blocks assigned to the first wireless section and a number of second resource blocks to be assigned to a second wireless section between the relay station and the mobile station;
• and
• transmitting the first resource block assignment information and the ratio to the relay station.

A relay station for relaying wireless signals from a mobile station to a base station, the relay station comprising:

• a receiving unit configured to receive data;
• and
• a resource block assigning unit configured to generate resource block assignment information, wherein
• the receiving unit receives, from the base station,
• first resource block assignment information of a first wireless section between the base station and the relay station based on a first propagation quality of the first wireless section, and
• a ratio between a number of first resource blocks assigned to the first wireless section and a number of second resource blocks to be assigned to a second wireless section between the relay station and the mobile station, wherein
• the resource block assigning unit generates second resource block assignment information of the second wireless section based on the first resource block assignment information and the ratio.

An operation method performed by a relay station for relaying wireless signals from a mobile station to a base station, the operation method comprising:

• receiving, from the base station,
• first resource block assignment information of a first wireless section between the base station and the relay station based on a first propagation quality of the first wireless section, and
• a ratio between a number of first resource blocks assigned to the first wireless section and a number of second resource blocks to be assigned to a second wireless section between the relay station and the mobile station;
• and
• generating second resource block assignment information of the second wireless section based on the first resource block assignment information and the ratio.

A relay station for relaying communication from a mobile station to a base station, the relay station comprising:

• a receiving unit configured to receive first resource block assignment information of a first wireless section between the base station and the relay station;
• a ratio determining unit configured to calculate a ratio between a number of first resource blocks assigned to the first wireless section and a number of second resource blocks to be assigned to a second wireless section between the relay station and the mobile station;
• and
• a resource block assigning unit configured to generate second resource block assignment information of the second wireless section based on the first resource block assignment information and the ratio.
