Abstract:
1. A method for allocating downlink frequency resources in a communication system including a base station that communicates in a cell that includes A sectors and uses a multicarrier scheme, the method comprising: allocating, by the base station, a first downlink frequency resource to a first sector during a first time period from a first timing point of a downlink frame; allocating, by the base station, a second downlink frequency resource to the first sector during a second time period from a second timing point of the downlink frame; and allocating, by the base station, a third downlink frequency resource to the first sector during a third time period from a third timing point of the downlink frame, wherein the first sector is one sector of the A sectors, the first downlink frequency resource is different from first downlink frequency resources allocated in each of sectors among the A sectors except the first sector during the first time period from the first timing point, wherein, when frequency resources, capable of usage in the communication system, are divided into A groups, the second downlink frequency resource is a first group as an arbitrary group among the A groups, and the first group is different from groups allocated in each of sectors among the A sectors except the first sector during the second time period from the second timing point, wherein the third downlink frequency resource is used to transmit dynamic channel allocation information, the third downlink frequency resource is identical to third downlink frequency resources allocated in each of sectors among the A sectors except the first sector during the third time period from the third timing point, and the dynamic channel allocation information is different from dynamic channel allocation information of sectors among the A sectors except the first sector, and wherein each of the first timing point, the second timing point, and the third timing point are not identical to each other, each of the first time period, the second time period, and the third time period may or may not be identical to each other, and A is an integer greater than or equal to 2.
