1. A frame constituting method of a wireless communication system, the method comprising:
- constituting, by a Base Station (BS), a subframe for a link affected by interference of a neighbor cell over a first frequency band of a frame; and
constituting, by a Base Station (BS), a subframe for a link causing interference to a neighbor cell over a second frequency band of the frame.

Abstract
An apparatus and a method for mitigating interference of a neighbor cell in a multihop relay wireless communication system are provided. The method includes constituting a subframe for a link affected by interference of a neighbor cell over a first frequency band of the frame, and constituting a subframe for a link causing interference to a neighbor cell over a second frequency band of the frame. Therefore, the interference between the neighbor cells can be reduced and the amount of the resources allocated to the links can be freely adjusted.

12. A resource allocating method of a Base Station (BS) in a wireless communication system, the method comprising:
-
confirming a distance between the BS and at least one of a Relay Station (RS) and a Mobile Stations (MSs) by using position information of the RS or the MSs; dividing into a link affected by interference of a neighbor cell and a link causing interference to a neighbor cell according to the distance of the RS and the MSs; allocating the link affected by the interference of the neighbor cell and the link causing the interference to the neighbor cell to different frequency bands; and communicating with the RS or the MS according to the allocated resource information. - View Dependent Claims (13, 14, 15)

16. A communicating method of a Relay Station (RS) in a wireless communication system, the method comprising:
-
confirming and sending position information to a serving Base Station (BS); when resource allocation information is received from the serving BS, confirming a frequency resource allocated to a link to the BS or a Mobile Station (MS) based on the resource allocation information; and communicating with the BS or the MS such that a link affected by interference of a neighbor cell uses a first frequency band and a link causing interference to the neighbor cell uses a second frequency band according to the allocated frequency resource. - View Dependent Claims (17, 18)

19. A communicating method of a Mobile Station (MS) in a wireless communication system, the method comprising:
-
confirming and sending position information to a Base Station (BS); when resource allocation information is received from the BS, confirming a frequency resource allocated to a link to at least one of the BS and a Relay Station (RS) based on the resource allocation information; and communicating with the at least one of the BS and the RS such that a link affected by interference of a neighbor cell uses a first frequency band and a link causing interference to the neighbor cell uses a second frequency band according to the allocated frequency resource. - View Dependent Claims (20, 21)
