The invention discloses a method and an apparatus of bandwidth resource allocation in a mobile communication system. The methods is used for dividing sector bandwidth resource into private bandwidth resource for only users in its own sector and a public bandwidth resource. The 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 bandwidth resource in the public bandwidth resource which has been allocated to users, located at a central area, of its own sector for use can be multiplexed by other sectors. The method of bandwidth resource allocation in a mobile communication system according to the present invention utilizes the resource of the adjacent cells efficiently, and resolves the interference among cells due to the bandwidth resource borrowing/multiplexing.
