Claim:
A method of bandwidth resource allocation in a mobile communication system, the method comprising: dividing, performed by at least one base station in the mobile communication system, a sector bandwidth resource into a private bandwidth resource for only users in its own sector and a public bandwidth resource, wherein bandwidth resource in the public bandwidth resource which is not allocated to users in its own sector for use can be lent to other sectors, and wherein bandwidth resource in the public bandwidth resource which has been allocated to users located at a central area in its own sector for use can be multiplexed by other sectors, wherein a first sector uses bandwidth resource which is an intersection of idle public bandwidth resource owed by other sectors in the same cell in which the first sector is located with borrowable and multiplexable public bandwidth resource owed by a cell adjacent to the first sector, when the bandwidth resource allocated to the first sector by the system cannot satisfy requirements of users, and other sectors in the same cell in which the first sector is located have an idle public bandwidth resource.
