Provided is a technique for efficiently using a channel bandwidth in a wireless communication system provided with a function for dividing a frequency channel into a plurality of segments and performing relay using the segments that differ from relay section to relay section. In a second method, an upstream direction of a first relay section 41 is DL, and two segments are used here. An upstream direction of a second relay section 42 is UL, and two segments are used. That is, 2/3 of an area is used in a frequency-axis direction, and 1/2 of the area is used in a time direction similarly to as in a first method. A data-area ratio DA2 for the second method becomes (1/2) × (2/3) = 1/3. A data-area ratio DA1 for the first method is 1/6. Thus, a throughput for the second method is twice a throughput for the first method. |
