An apparatus and method for allocations segments in a broadband wireless communication system is provided. Sector pairs are generated with respect to all sectors existing in different cells and the generated sector pairs are sorted according to priority based on a proximity. A sector pair having a top priority among unselected sector pairs is selected. Segments are allocated to all sectors of a cell including each sector of the selected sector pair. Accordingly, segments can be allocated to sectors while minimizing downlink throughput deterioration caused by segment duplication.

Apparatus and method for allocating segments in broadband wireless communication system

An apparatus and a method for allocating IDcells in a wireless communication system are provided, in which an initial IDcell allocation is performed by allocating entire sectors to elements of an N&#xd7;M IDcell matrix, a sector pair with the highest proximity is selected for each IDcell in the initial allocation, an IDcell with a sector pair having the highest of the proximities of the selected sector pairs is determined as a target IDcell, one sector of the sector pair with the highest proximity for the target IDcell is selected as a target sector, a predetermined number of sectors are selected for each of the other IDcells except for the target IDcell, from among sectors to which the each of the other IDcells is allocated, and the IDcell of the target sector is swapped with the IDcell of a sector satisfying a first condition among the selected sectors.
